*Readers should refer to the definitions below only after they have read the text which uses them. Wealth preservation is not the same as the preservation of purchasing power. The early paragraphs explain why the preservation of wealth is better measured in units of National Average Earnings, NAE.*

INTRODUCTION

The following definitions are based upon a conclusion reached when doing thought experiments on how to estimate the rate at which prices would need to rise in order to offset the falling value of money.

Money can buy many things including assets of all kinds, debt as an investment such as bonds, property, hiring people (incomes), in fact anything which you may be able to pay for including your mortgage repayments.

If we were to replace the usual basket of goods with such a basket, and defined the rate of inflation accordingly we might bet a more accurate figure.

The problem is that some things are not able to adjust for the falling value so in respect of those items the value of money or the rate of inflation, so defined, would be different from what it may be if all prices are free to adjust. In that case all of the prices, other than those which are affected by increasing production or efficiency, might be rising at about the same pace.

We might also say that if there were no impediment to any price of any good, service, income/earnings, costs, interest rates, or currency price, and all were free to rise at the same rate as a part of offsetting the falling value of money, then National Average Earnings, NAE might be rising at about that kind of rate, albeit undulating relative to that measure over time.

It would not be a perfect measure but it is possible to improve the stability and the manageability of much of the economy by writing contracts as if this was the measure to use.

Here are the concepts to sell to people and the financial services products which go along with that. The overwhelming advantage os using NAE as a benchmark is that so many liabilities in the financial sector and so many revenues all rise at a rate which is linked to that. What people earn is ultimately what they spend after leaving some proportion aside on deposit or in cash for easy access.

Sometimes they save and the savings get lent, sometimes they spend their savings or pass them on to the next generation. Sometimes people import more and that takes spending out of the economy. At other times the import less giving a boost to it.

Sometimes people borrow more and sometimes they borrow less.

On average over the longer term apart from funds needed for immediate access all earnings get spent or they would be accumulating somewhere. No such treasure has been found on planet earth.

LOOKING TO THE FINANCIAL PRODUCTS RESULTING

Most people will want their investments to keep pace with the rising income of others, their pension payments to do the same, and they can relate to repaying the amount of National Average Earnings, NAE, which they have borrowed, out of income, plus interest.

A loan is an investment to one entity - an investment with a claim to a share of the future earnings / income of the borrower.

So it makes a lot of sense to use these NAE units in the construction of contract, or in the calculations needed to find a safe level of repayments. All such repayments are of value. They do not have to rise and fall as nominal rates of interest vary.

Whether or not the investment will provide a positive return in terms of adding units of NAE is up to the rate of interest relative to the rate at which NAE is rising. That comes down to market forces acting in the credit market - always remember that.

With that in mind a considerable amount of research has been done to see if the return on lending would be positive, given free market pricing of interest rates and other prices being free, and given a sustainably growing economy without too much money in circulation or too little plus or minus undulations.

The conclusion reached from several viewpoints is that the return on secured loans would be positive. The key viewpoint is that cheap money leads to abused resources and in some situations to run-away inflation. It has to cost some NAE to restrain the aggregate level of borrowing and the money creation which goes with that. There is a mean rate of marginal interest above the rate of growth of NAE, Average Earnings Growth % p.a.

Too much credit is risky.

If we do not adopt any such index and just aim to repay money, not value, we will always be in a crisis or moving in or out of one because the way that the repayments are calculated is highly unstable in outcome.

And bond values can crash down fast under the influence of a small interest rate increase. There is a report that a 1% rise in USA interest rates would slash $2trillion off asset values which is considerably more than the losses in 2008.

W really need to take out that kind of asset value and cost of repayments instability for otherwise monetary policy or the rate of free market interest (in either scenario) will have too many conflicting pressures to cope with. See the LOW INFLATION TRAP.

**Another key point which needs to be raised is this: if all prices are not free to adjust to all market forces including those which ought to exist relating to the offsetting of prices to the falling value of money, then the prices will be distorted in every such case.**

**Distorted prices lead to re-distribution of wealth, broken businesses and repossessed homes and they provide a great platform for extreme political movements and the fall of good governments.**

----------

*Please be patient and learn this introduction. It will completely change your understanding of savings and lending.*
NAE units can be used to value things which you could sell, but then the value in NAE which you will get when you sell is not certain. It depends upon what people are willing to pay. The question to ask is, "How many years of my income will I get when I sell it?" and then, "How much different is my income than the national average?" You will spend most of your own income in your own nation, just like most other people do, so the answer you get will tell you something important to you.

When you or a lender, values the loan which was made to another person, its value is a call upon the earnings of that other person plus any interest which has been agreed. You may know how many NAE you lent, but can you, or can that lender, be certain about how many NAE that person will repay? That depends upon what is written in the contract and the collateral security that secures it in the event of default.

KEEPING PACE WITH INFLATION IS NOT WHAT IT SEEMS

Before readers can write a contract that gives any certainty about how many NAE will be repaid, it is important to get familiar with the following fictitious example of what happened to an investment which specified that the fund must retain its purchasing power over a 100 year period.

AEG% p.a. is short for Average Earnings Growth (for the nation). It is the rate at which NAE is rising / growing.

Now read this:

Take a savings account of 20 NAE, about half a life time's earnings for an average person - 20 years earnings. Let it attract AEG% p.a. growth, or interest equal to AEG% p.a. After 100 years there will still be 20 NAE in the fund. But if the fund rises 3% p.a. more slowly, at the rate of prices inflation, say, there will be only 1 NAE - a single year's spendable income in the fund.

The true rate of interest, I% p.a. is the marginal rate above AEG% p.a. So is AEG% p.a. = 5% and the nominal, or total rate of interest, is 7%, then the true rate of interest is defined as r% - AEG% = 2%.

If we say that r% is the nominal rate of interest, then it has two parts: AEG% and I%.

r% = AEG% + I%.

Now read this:

I like to explain that I% has a very special meaning in finance and economics which has been missed in the text books.

If I% true interest is then the number of NAE in the fund will increase.

If the fund is lent to a borrower, the number of NAE needed to repay that loan will be quite a lot higher if I% is a positive figure.

But that depends upon how the contract is written. Will I% even be mentioned? Or will it vary as r% varies? How will r% vary?

r% has two components, AEG% and I%. Both of these can vary.

When borrowing using a fixed interest r%, the number of NAE which you will repay depends upon the ever changing value of AEG% p.a.

Let us say that you agree to pay 5% interest and that AEG% = 5%. If that never changes then the number of NAE which you borrowed will be the exact number of NAE which you will repay. The fact that NAE may triple in the meantime from, say 10,000, to 30,000 in the meantime, (in any currency), makes no difference.

Here is an example.

*Source: E C D Ingram Spreadsheet.*

The value of r% is all over the place but AEG% follows it exactly. The payment is made not in the current year but after 12 moths and after the pay increase at AEG%. The total % of AEG is found by adding up the figures in the final column. The total NAE paid is the same as the 1 NAE borrowed.

OLD TEXT

The problem is that one borrower's income never looks like the National Average Income or Earnings (NAE), which is what we have to use to evaluate the cost. Each borrower's income grows or falls in its own way. But there is no way to evaluate that or to use that unknown as a way of projecting / estimating the cost.

One thing to note: This calculation can be applied to ANY form of mortgage or loan repayment. It has advantages over comparing the money or costing relative to the prices index - the so called real cost.

Firstly, it IS what it really costs in terms of national average wealth or NAE more specifically.

Secondly, any up-front costs get the highest weighting as they need to.

Thirdly, money costs can be highly misleading, as can real costs. People have a limited resource called income. They do not have purchasing power only. How that income is deployed tells us what can be afforded for housing and pensions and everything else. The purchasing power may rise, but that happens to everyone. It may fall and that happens to everyone.

When purchasing power falls, it falls for everyone. Wealth falls for everyone. true rates of interest (above AEG% p.a.) may fall, or not, but AEG% p.a. may fall relative to prices. At least anyone keeping pace with AEG% p.a. keeps their share of wealth and the borrowers can afford to repay because market forces will tend to keep true interest rates within the expected range over the medium term.

**THE GENERAL EQUATION FOR LENDING**

Here is an equation that describes pretty well every kind of
lending ever invested. Do not be scared by the equation - it is just easier to explain things this way because every loan has each of the variables shown here as explained next:

P% = C% + D% + I%

Every loan has a current level of payments P% p.a.

Every Loan repays some of the debt, C% p.a.

Every loan has a rate of easement of the cost D% p.a.

Every loan has a rate at which wealth is added to the debt
by the marginal (true) interest rate I% p.a.

The interest rate I% used is not the nominal rate of
interest: it is the marginal rate above the rate of increase of average
incomes growth (AEG% p.a.) or of nominal GDP% growth p.a. Only if the nominal interest rate is higher than (nominal)
GDP% p.a. growth rate or AEG% p.a. does wealth get
added to the debt. Then more income (share of GDP) will be needed to repay than
the income or share of GDP that was borrowed. This is the big thing to watch. But there is another big thing to watch too...

...What makes a lending model unsafe is when there is no
control over the value of D% p.a.

D% p.a. is the rate at which the amount (portion) of your income or national wealth (NAE) needed to repay the debt reduces every year. Remember we are not really talking so much about your income, as the share of GDP or the number of NAE that is owed and how much of that is repaid every year. If your income is rising as fast as average then the value of D% will apply to you. Typically D% may be around 4% p.a. so every year 4% less wealth / NAE should be needed to make the payments, or maybe 12% less every three years.

That is the target used for the new ILS Mortgage model.

The problem for other models like fixed interest mortgages and variable rate mortgages is that they have no real control over D%. D% is then equal to the rate at which incomes are rising - until the interest rate changes. Then it leaps around. Completely unsatisfactory.

To ensure that D% can always be positive the theory on the maths pages shows that the initial income multiple lent must not vary much over an interest rate cycle.

This has a stabilising effect on what can be borrowed and on the price of and affordability of housing.

**HERE ARE THE NEW PRODUCTS**

**1. An ILS Defined Cost Mortgage.**What the ILS Defined Cost Mortgage does is to fix the value of I% pa. This means that the lender has to sell fixed true interest rate 'wealth bonds' as the financing method. That protects the wealth of the bondholder.

This way the value of D% p.a. can also be fixed. There will always be a falling cost for the repayments if D% is positive and if D% p.a. is a fixed rate of 4% p.a. then the outcome will look something like this:

FIG 1 - all figures use an index of average incomes, not individual incomes.

The total amount of wealth repaid is always given by the size of the shaded area which represents a series of columns of income paid each year and added to together to give the area.

After a few years the cost of the defined cost mortgage should become less than the cost of renting a similar property, as shown in FIG 2 below. Rentals tend to follow the dashed line, keeping pace with average incomes and costing a steady 21% (say) of income in this illustration. The Mortgage costs more at first at 30% but falls towards 11% over time as shown.

FIG 2 - ILS Defined Cost Mortgage Payments v Rental Costs

In all of these illustrations the total wealth paid across is given by the shaded area which is like a series of columns of annual payments set side by side. So the total area is the total cost to income / share of GDP.

The problem with most mortgage models is that they do not have control over either I% or D%.

We will see how that affects the shape of the above sketch a little later.

VARIABLE RATE ILS MORTGAGES With the ILS Model, variable interest rates (and so variable I%) can also be offered. In this case no sudden increases in costs should occur even if interest rates rise significantly because interest rates always revert to mean and the initial set-up and the amount lent will usually have been based more with the mean conditions in mind than with current conditions.

The difference between this and the defined cost mortgage is that the steepness of the slope varies and is not a constant.

ILS MODELS CAN ALWAYS COMPETE

Traditional mortgages often over-lend when nominal interest rates are low, and then they inflate property prices. If the interest rate is not fixed then when interest rates rise again there are large numbers of defaults and arrears which have significant social and economic and lending costs.

The ILS Model can be used to rescue lenders and borrowers in such conditions. However, normally, the ILS models are based on maintaining control of the arrears risk: D% must be positive so that the steepness of the slope must always be downwards.

Broadly speaking, it achieves this by using the median rates of interest as the basis when deciding the safe amount to lend. This lowers the risk of arrears and it stabilises mortgage sizes if the model is widely adopted or enforced. If all lenders were to abide by these rules then that in turn would stabilise property values so that smaller deposits will be needed, and property price bubbles will not appear and then threaten the stability of wealth invested in property nor the health of the economy.

PROBLEMS WITH FIXED INTEREST RATES - using the traditional mortgage model It is not healthy for an economy to have people struggling with their mortgage payments during a recession, as can happen with fixed interest mortgages or having their mortgage costs jumping up by many times more than next years' pay rise, as can happen when interest rates rise after a period of low interest rates or booming economic growth.

With fixed interest rates the value of I% varies all the time. If incomes start falling or do not rise as fast as hoped, then the mortgage will cost far more than expected.

Here is what happens when fixed interest rates are used for mortgages during a period of austerity:

FIG 3

The lender starts the repayments using 30% of income as always, but because incomes are not rising the payments get stuck at 30% of income.

FIG 4 - It can be worse if incomes are falling:

**MORE ACCURATELY**

**The Ingram Lending and Savings (ILS) Model for Mortgages**

The above illustrations use straight lines to illustrate declining payment costs. If we use an EXCEL sheet to calculate them and then display this as a bar chart it may look more like this:

FIG 5 - Here a Fixed Interest rate Mortgage (NOT ILS) is illustrated with incomes rising at 10% p.a. which reduces the 'wealth cost' (% of income) by 10% p.a. D% = 10% p.a.

**2. Wealth Bonds.**

A wealth bond is a bond whose value is index-linked either to average incomes or to a measure of GDP that represents average incomes in an acceptable way. The interest coupon would be fixed and would be the fixed value I% in the general equation above.

Defined Cost Mortgages are funded by wealth bonds in which I% is fixed. Such a wealth bond would suit a pension fund or anyone wanting a relatively risk-free place to put their savings.

Currently there are no wealth bonds available to a pension fund or to anyone else, except in Turkey where a mortgage model somewhat similar to the ILS Model is in use for Civil Servants. The problem is that the value of D% = 0%. That is far too low for comfort.

HOW THIS WORKS

A wealth bond repays the same amount of wealth (lifetime's income) as was lent plus the interest coupon.

To raise funds with a wealth bond you will almost certainly have to pay an interest coupon.

If the market rate for wealth bond interest is higher then more wealth (income) will be repaid by an average borrower whose income keeps pace with the index.

LENDER'S LIQUIDITY: If a mortgage is funded by such a bond the lender will have much reduced liquidity / funding problems, with, as just mentioned, virtually no arrears except due to redundancy etc.

REDUNDANCY: If the borrower loses his/her income in the early years this might be insured for long enough to repay enough of the wealth so that after that the repayments might be suspended allowing the interest to roll up for a while. In the last resort, a repossession of sale of the property will protect the investment made in the mortgage.

MORE USES FOR WEALTH BONDS

**2a. House for life no matter what.**Some retiring older people may have repaid 90% of their mortgage and then they retire. Then the lender can slow down the payments to interest only or less. The equity in the home can pass to the lender if necessary, and well, we can discuss what the possibilities are to give them their home for life.

**2b. Lifetime Annuity.**In these circumstances a lender might offer a home for life on a group basis, taking equity in return for life tenancy. The longer lived could be financed by the shorter lived. In other words the home becomes a lifetime annuity.

**2c. Low deposits, safer wealth.**With more stable property values (assuming that lenders stop over-lending when interest rates fall), more can be lent to first time buyers; and this kind of annuity for retiring people (in 2b) also looks more practical because the value of the property at death can be better relied upon.

**MORE ILS MORTGAGE MODELS**

**3.**

**A Hybrid Mortgage.**People do not like trying new things unless they have to save their home or something they hold dear.

An ILS Hybrid Mortgage is the familiar variable rate LP mortgage with an option to switch to the ILS model when interest rates rise.

When the ILS Model clicks in it ensures that the rate of increase in the repayments does not exceed the rate of increase of average incomes (AEG% p.a.). If the suggested regulations on mortgage sizes (maximum wealth lent and minimum repayment level) are enforced to prevent over-lending, or if the lender's own risk manager enforces this, then there will be no problem here for lenders. Then the ILS payments will be able to fall at about the usual 4% p.a. as in FIG 1. The lender may be able to arrange a Defined Cost replacement Mortgage, or if not, the slope of the bars will vary somewhat over time.

In the event that the lender lent too much then the slope of the bar s will be less because too much was lent.

**3a. ILS Rescue Mortgage.**This is the same Hybrid arrangement but unplanned in advance. Because too much was lent under the traditional mortgage model, the rate at which payments can fall relative to AEG% p.a. will be reduced. If possible lenders will shop around for an attractive Defined Cost option. The cost depends upon the market rate set by investors wanting a defined benefit bond, otherwise known as a 'wealth bond' because it protects and adds to wealth in return for protecting the borrower's wealth and funding the mortgage.

*An illustrated example of how an ILS Rescue might have looked in 2008 in the USA is given at the bottom of this page.*

**4. Rent-to-buy options.**This is a useful way of hiding the mortgage from view if interest rates are high and the mortgage has to rise in money value in the early years. As long as the property collateral is good and incomes are rising faster than the debt by a good margin, and as long as the payments are rising faster than the amount of the debt, there is no problem. The debt will be repaid on time. In the meantime, the lender will take ownership of the property which will be rented to the buyer in terms of legal rights. The risk of this failing can be predetermined by the risk manager who decides the maximum safe loan to offer. The risk can be very small even for a sizable loan.

This is ideal for some developing nations. Zero deposits are possible with this model because it starts life as a pure rental.

what is going on. They can be seen on the

**5. Wealth Bonds can come in various forms and have various uses**

A wealth
Bond can be issued by a lender or a private person or a business.

A wealth Bond is basically an AEG-linked Bond or a GDP- linked Bond with interest added. The
indexation can be done as a variable rate of interest that tax free and is equal to the rate
of Average Earnings / Incomes Growth (AEG as defined by the lender or the national authority), or maybe the link could be to GDP. Governments may prefer GDP but sales may be faster for AEG.

**6. RETIREMENT PLANNING**

**Gamma Rated Funds**

For
investment funds for where wealth protection is needed using AAA rated
government bonds or secured mortgage bonds a wealth bond is very attractive.
This is especially so if you are involved in retirement planning and fund
management. For example:

**WAS BETA, NOW GAMMA**

Whereas
sales people and financial planners usually talk of Beta (volatility
relative to the market) we will be able to introduce (shall we say) gamma -
'volatility relative to wealth'.

**A Gamma Rating will be a measure of wealth risk.**A Gamma Rating of 1.0 is much more interesting than a Beta Rating of 1.0 to those that want to invest and at the same time protect their wealth.

"Beta ratings are a measure of stock-market volatility.
Stocks with a beta of 1.0 have exactly the same degree of volatility as the
market they trade in, based on a comparison of fluctuations in the stock and
the market index over a period of time, usually five years."

If a stock market investment’s beta is below 1.0, the stock is
less volatile than the market. High-beta stocks above 1.0 are generally more
volatile than the market. (If a stock has a negative beta, it has an inverse
relationship with the market; it tends to fall when the market goes up, and
vice versa.)

A gamma
rated fund (more volatile than stable wealth with a Gamma Rating of say 1.2
might have 80% or more invested in AEG-linked mortgage bonds and/or
government-issues wealth bonds if the government bonds were AAA rated with the
balance invested in, say equities.

A higher risk,
gamma rated fund, (maybe around 1.8 or even more), would have maybe 20%
invested in wealth bonds and 80% in equities.

A person
wanting to get completely out of risky investments in pre-retirement would go
for a 100% AEG-linked mortgage bond (wealth bond) or a government wealth bond
similarly index-linked - if it was on offer. Financial advisers will readily
suggest this as they have told Edward (the innovator going back to the 1970s although others have claimed to be have made the same invention since) when asked.

A fund that is 100% invested in wealth bonds would be a 1.0 rated on gamma, (no
wealth risk) but with two cautions:

1. No investment is ever quite risk free. For the risk look for the
credit rating and look for a AAA rating.

2. Average incomes are defined by
a third party and may not be quite the average / index that the
person might prefer. Hopefully, we will be able to set up an official measure
for AEG indices that takes account fairly of the various interest groups.

**BUSINESS FINANCE**

Wealth
Bonds can also finance businesses and also get an investor risk rating. The
risk rating is not the same as the Gamma Rating. As just explained, the risk
rating is what it always has been - AAA or less. The Gamma rating is just the
wealth protection rating in the event that the investment itself was entirely
risk-free - beyond AAA.

Wealth Bonds will make business borrowing much safer and more flexible, thus
improving their own risk rating and possibly reducing the cost of financing a
business.

**7. Annuities.**The high cash flow obtainable from mortgage bonds can be matched to annuities and at the same time take out the considerable wealth risk of a fixed interest annuity. Some clients may want a mixture of more than one kind of annuity. Secured AAA rated Index-linked investments for annuities would extend their choice.

**8. Government and Business Debt.**Both governments and businesses may have a range of cash flow needs and so do investors. A market will develop to match the interests of all parties as far as practical.

Some wealth bonds will pay interest only until maturity. Others will repay the
debt as if it was a mortgage over various selected periods so as to tap into
the market at an economic rate for the borrower.

**DEFINITION OF WEALTH**

The wealth that a person may be able to accumulate in
a lifetime is the product of their lifetime's income.There are at least two kinds of inflation:

Prices Inflation

Incomes Inflation

In an economy where incomes all rise on average by 300% over a long time, if the output of the economy has not altered, then it just takes 300% more money to buy everything. Money has been devalued.

If you want to preserve the wealth that you saved you have to preserve the value of your savings with a 300% increase in the money value. If you get less, then you can buy less of the national output. Others can buy more of the national output because you can buy less. Some of your invested wealth (spendable income) has moved from you to others because you lent it too cheaply.

If you want to preserve the wealth that you saved you have to preserve the value of your savings with a 300% increase in the money value. If you get less, then you can buy less of the national output. Others can buy more of the national output because you can buy less. Some of your invested wealth (spendable income) has moved from you to others because you lent it too cheaply.

If the part of that lifetime's income that is invested / lent can be protected from incomes inflation, then that amount of wealth is protected.

It is not enough to protect the savings from inflation
of prices.

**For another example:**

If you lend me 3 years' income and I repay you with
two of my years' income (taking into account all of the interest that I pay to
you as well as the rate at which incomes are rising), you will lose a year's
income. I will spend the three years' income and then I will repay two years'
income and then I will spend another years' income (of yours) that you let me have by
lending to me too cheaply.

Here is a tabulation of that happening:

FIG 9

**-**Average incomes (AEG% p.a.) are rising 3% p.a. faster than the interest rate giving a -3% true rate of interest (the difference). When true rates are negative wealth flows from the lender to the borrower. The figures at the bottom add up the '% of income' (total wealth cost) used every year (final column) and show the total number of years of income spent in repaying the debt as well as the number of years of income borrowed. The two figures, wealth borrowed and wealth repaid, are compared in 'years' of income' at the base of the table.
Remember - the total wealth that each person may be able to spend is the total of their life-time's income plus or minus any income that is lost to them through investments and/or through lending. Any wealth gained or lost in those ways comes from another person or from the community as a whole or from an inheritance maybe. Total National Income does not vanish - it gets spent by someone or saved, and then spent or held (bank deposits) by others in return for an interest rate cost.

Here is another way to say this:

Suppose that everyone got a 5% raise on the same day.
This does not increase national output. It devalues money by 5%. It does not matter that in practice this increase is not instantaneous, nor that it is not the same increase for everyone. The outcome is the same, only changing if the prices and costs of goods and services have had time to alter.

So in terms of wealth we have to keep pace with rising
incomes (AEG% p.a.) to protect wealth (income) that has been saved / invested.

For a defined cost mortgage you define how many years'
income will be repaid based upon an agreed, or an appropriate index of incomes. You define the true rate of interest that will be applied. You also agree that more will be repaid in the early years at say 4% less
every succeeding year. You have no arrears problem. Your collateral security is
good. The investment in the loan is AAA rated. The lender gets wealth
protection.

FIG 10 - Here is an illustration of how a defined cost mortgage may have worked for South Africa 1981 - 2005. The interest rate is defined by the rate of AEG% plus an agreed 3% (true interest):

But compare how the money balance compares to income at the end of every year. The income is rising much faster. Note that the mortgage starts at over 3 times income and by end year 9 it is only twice income. A year's income (wealth) has been repaid already. This can be dressed up as a rent-to-buy contract so as to give the buyer some peace of mind. For more comment see the reply at the end - below.

This is a case where the rent-to-buy format should be used.

The assumption made is that the borrower's income will change alongside the average, which clearly it will not do. But that difference affects the cost-to-wealth of every kind of mortgage with very similar effects: less well paid people ALWAYS feel more stress and vice versa.

Notice that despite the cost of the payments not rising much at all at first after the fourth year jump in interest rates and slowly thereafter (see FIG R2 below) this does not lead to the mortgages increasing above the original amount of 100,000. See Orange year-end balances.

The outcome for the payments is very different. They become unaffordable in year 4 for prime borrowers after a 58% jump from 5,437 p.a. to 8595 p.a., never mind sub-prime. Many prime borrowers had no capacity to increase payments as they had credit cards to repay.

The mortgage is so large at 5.22 years' income that there is little room left for payments depreciation, now set at 0.5% p.a. for the ILS Rescue Model, as shown. The ILS Model normally aims to repay in 25 years, whereas the Americans like to offer 30 year terms. A 30 year term allows more to be lent but it raises the cost of all properties and reduces margins of safety. It increases the total cost-to wealth disproportionately as interest has to be paid on high value debt fro an extra 5 years at the start. The alternative ILS Rescue Model here would be to extend the repayment period which actually gives a lot of relief allowing the downwards slope (payments depreciation to reach 2% p.a.).

This is a case where the rent-to-buy format should be used.

And

The assumption made is that the borrower's income will change alongside the average, which clearly it will not do. But that difference affects the cost-to-wealth of every kind of mortgage with very similar effects: less well paid people ALWAYS feel more stress and vice versa.

When we measure wealth we cannot measure it in terms of one person's income or lifetime's expected income. We can only use national statistics to measure wealth. We can only say what part of the national wealth an individual has earned or has saved and owns.

Does this mean that lenders must always use the national figures to define AEG% p.a. - the index of average incomes growth? They don't have to. But if the rate at which the repayments fall relative to the national index is set high enough it should suit most people.

And it is something that investors in mortgage bonds, wanting to know what wealth they have and what wealth increase to expect, will be able to understand.

**REPLY TO A READER**

Based upon the rate of incomes growth the value of the property should be moving up somewhat similarly over time. A deposit would help as suggested by the reader, of course.

But look - the income starts at about a third of 100, 000 but BY YEAR 9 it reaches 100,000. Properties tend to rise with average incomes so they might be worth three times as much by then.

On the other hand, you don't package high interest rate mortgages this way. You have to do a rent-to-buy model to hide the rising debt.

Furthermore, if you read the earlier pages of this blog you would hope that all lenders are doing things this way and that this and the other measures suggested would end such volatility in the property markets. Because there are a lot of distortions taken out of the economy by the ILS Models and by Wealth Bonds, interest rates may also calm significantly. That is one of the BIG objectives of having these financial products.

The other point made by the same reader was that in America interest rates jumped up by over 4% and property values crashed in 2008...

There is a detailed illustration of how an ILS Rescue Model could have coped with much of that. In fact, based on some projections, despite interest rates leaping up from 3.5% or so to 8% the ILS mortgage debt did not rise above the starting level, (FIG R1 below), yet the payments were made affordable and so property values need not have crashed so much. Sub-prime would have taken its toll but not so much as it did. Here are some of the illustrations of that:

**AMERICAN RESCUE BY ILS HYBRID**

The ILS Hybrid model starts like an ordinary variable rate or adjustable rate mortgage. The ILS model clicks in to rescue the lenders and the borrowers when the 'experts' at the central banks, the regulators, and the lenders all get it entirely wrong like they did in the USA.

WHAT TO AVOID

It is NOT recommended that lenders get it wrong but then they did didn't they? They lent far too much and lowered the entry cost of first year mortgage payments far too low as interest rates reduced. The mathematics of risk management done by Edward on the

**INGRAM SCHOOL**pages says that is not the way to do things. Mortgage sizes and costs should not be greatly influenced by the nominal rate of interest. Property prices would not then over-inflate by much - the estimate is less than 10% even in extremely low interest rate cases.
FULL ILLUSTRATION

MAKING UP THE TEST FIGURES

The figures made up for this illustration show incomes rising at 4.5% p.a. (on an upward trend) while interest rates on 30 year mortgages were fixed for three years at 3.5%. In the fourth year they leap up to 8% which is about 1% above Edward's projected level to rein in inflation in a balanced economy (

**the mid-cycle rate of interest**) and was about the same as the Fed had eventually estimated by trial and error, was needed.
In this illustration, only the first years were deemed to be a problem so economic undulations in incomes growth and interest rates after the early years have not been included in the later years' data. They have been set at long term average rates for a stable economy, based on past data averages.

**FIG R1 below - Here the ILS Model intervenes to rescue the American Banks from arrears due to a rise in interest rates from 3.5% to 8% all in one jump at the end of their third year fixed rate term (this is called an Adjustable Rate Mortgage).**

Notice that despite the cost of the payments not rising much at all at first after the fourth year jump in interest rates and slowly thereafter (see FIG R2 below) this does not lead to the mortgages increasing above the original amount of 100,000. See Orange year-end balances.

**FIG R2 below - Here are the figures used for the ILS Rescue Model.**The year end balances and the income figures and the payment figures appear in FIG R1 above.

**FIG R3 below - These are the same interest rate and AEG figures as seen in FIG 2 above and applied to the traditional US Adjustable Rate Model.**

The outcome for the payments is very different. They become unaffordable in year 4 for prime borrowers after a 58% jump from 5,437 p.a. to 8595 p.a., never mind sub-prime. Many prime borrowers had no capacity to increase payments as they had credit cards to repay.

**FIG R7 below - shows how all of the % of income figures may have compared if rentals had cost 70% of the first year mortgage cost and then risen as fast as average incomes (AEG% p.a.).**Normally, the ILS Model is cheaper after around 12 years, but that is when the mortgage size is set correctly to allow 4% p.a. payments depreciation. If you buy these spreadsheets all of these bar charts are generated automatically and you can insert whatever assumptions you wish. Rental can start at any figure, not only 70% as here, for example.
