Monetary Savings Versus Real Savings

Every quarter the national accounts publish a figure for how much the country saved, and every quarter it is discussed as though it were a measure of thrift. It is not. It is a residual: money income, minus tax, minus money spent. Whatever is left over is called saving. The number is arithmetically sound and it answers a question almost nobody is asking.

The question people think it answers is whether the country is putting something aside for the future. That is a question about goods, not about dollars, and the two can move in opposite directions for years at a time.

What the accounts actually measure

The framework behind the figure treats one person's spending as another person's income. Add up all the spending and you have the national income. It follows that anything raising the amount of money spent raises measured income, and anything raising measured income raises the residual we have agreed to call saving.

Notice what that means. If the money supply grows, money incomes grow, and the savings figure can rise without one extra loaf, bolt or bushel existing anywhere. The measurement has no way of telling the difference, because it never looks at goods at all.

What saving actually is

Consider a fisherman who catches enough each day to feed himself and no more. He can never stop fishing, so he can never build a better boat, so he will be catching fish by hand for the rest of his life. Now suppose he dries and stores a portion of every catch. After some months he has a surplus, and the surplus is what lets him spend the winter building a boat instead of fishing.

The dried fish are the savings. Not a number, not a claim, not a balance. Food that exists, was produced, and was deliberately not eaten. What they buy is time: the months during which somebody can work on something that will not feed anyone until it is finished.

An economy is that fisherman many millions of times over, and the boat takes years rather than a winter. Between the raw material and the finished good sit stages, and at every stage there are people who must eat today while producing something that will not be usable until later. The goods that feed them were produced earlier by somebody else and set aside. That set-aside stock is the real thing the word saving refers to.

Money is the claim, not the thing

None of this is an argument against money. Without it the fisherman would have to find a boatbuilder who happened to want dried fish, and in that world there are no boats worth having. Money is what lets the surplus of one trade support work in another.

But money earned by producing something is a claim on goods that already exist, and money created by expanding credit is a claim on the same goods with nothing behind it. When it is spent, goods move in one direction and nothing moves in the other. The claim is honoured. It is honoured out of the same stock that was meant to feed the people at the earlier stages.

Which is why the two figures come apart

An expansion of credit raises money incomes across the board. Measured saving goes up. At the same moment, the stock of goods available to support production at the early stages is being drawn down by spending that no production stands behind. The published number rises while the thing it is supposed to represent falls.

This is not a subtle statistical quibble. It is the difference between a country that is building its next decade of productive capacity and one that is quietly eating it, while both report the same encouraging figure.

Why it matters

If saving were really a matter of money balances, poverty would have been solved long ago by the simplest policy imaginable. That it has not been is the strongest available evidence that the accounts are measuring the shadow rather than the object.

The practical conclusion is narrow and firm. When the savings rate is cited as proof that an economy is provisioning for the future, the right question is not how many dollars were left over. It is what was produced and not consumed, and who is being fed by it while they work.
