The last people we should ask about government finances

Posted on

In my opinion, if we want to understand government finances, the last people we should ask are businesspeople and the City of London.

That might sound surprising to those not familiar with a heterodox viewpoint. Businesspeople deal with money all day, whilst the City supposedly exists to understand finance. But there are very good reasons why neither provides a sound basis for understanding government finances.

The microeconomic problem

The first problem is that businesspeople almost invariably think in microeconomic terms. For a business, spending is constrained by the money it can obtain. It can spend its income, use existing cash or borrow. What it cannot do is simply create the money it needs to make a payment. The same is true of households.

That is not true of a government that issues its own currency. The UK government is not a household, and it is not a business. It is the issuer of the currency that households and businesses use. That difference is fundamental.

The government can create pounds. Ordinary businesses cannot.

Commercial banks are the exception because they create new money when they make loans, but that privilege exists because the state licenses and regulates them. Any other business trying to manufacture its own pounds is likely to find its owner spending some time inside a prison wall.

So, when businesspeople apply their experience to government and say, “You cannot spend what you haven't got”, they are applying the wrong model. The government does not have to get pounds from taxpayers before it can spend pounds.

Logically, the opposite has to also be true. Money has to be created before anyone can use it to pay tax. That payment would not be possible if government money creation did not come first.

The double-entry problem

This should be obvious to anyone familiar with double-entry bookkeeping. Every financial asset has a corresponding liability. Every debit has a credit. One person's financial asset is necessarily matched by someone else's financial liability. Government finances cannot, therefore, be understood by looking at the government's accounts in isolation. The government's financial position has to be considered alongside that of the rest of the economy.

That means a government deficit necessarily creates a financial surplus elsewhere. If the government spends more into the economy than it takes back in tax, somebody else must end up with the resulting financial asset. That is not an opinion. It follows from accounting. Businesspeople, however, rarely seem to appreciate this, or, if they do, routinely forget it when discussing government finances.

The status quo problem

The City of London has an additional problem. The existing understanding of our financial system suits it very well. The City likes the idea that governments depend upon financial markets because that supposed dependency gives financial markets enormous political power. It allows them to claim that governments must maintain “market confidence”, satisfy bond traders and design economic policy around the wishes of financiers.

Why would the City want to challenge a story that gives it so much influence? That makes them far from objective commentators when the media question them.

The money creation problem

There is another problem, however. The City, like much of business, talks about money as though it were a commodity that exists independently of the economy. It does not. Money has to be created.

In the modern UK economy, new money is created in two principal ways. Commercial banks create money under licence from the Bank of England when they make loans, and the Bank of England creates money when it makes payments on behalf of the government. These are the only sources of the sterling money that the economy uses.

The sequencing matters. Until money has been created, it cannot be spent. It cannot be taxed. It cannot be saved. It cannot be deposited. It cannot be used to buy government bonds. The money has to exist first.

The money is not a thing problem

This brings me to the biggest misunderstanding of all, and the most significant issue that business and the City do not appear to understand.

Money is not a thing. People talk about money as though piles of notes and coins somehow move around the economy whenever payments are made, but that is not what happens. Money is a record. A banknote records a promise. A coin is a token representing one. A bank balance is an entry in a ledger.

An entry in a ledger is profoundly different from a physical object. A chair can exist by itself. A financial asset cannot. If there is a debit, there must be a credit. If someone has a financial asset, someone else must have a corresponding liability.

Money can therefore only be understood as part of the system of assets, liabilities, income and expenditure of which it forms a part. Trying to understand money in isolation from those relationships is meaningless. But that seems to be exactly what business and City commentators on government finance and money seek to do.

And that is precisely why relying on them to explain government finance is so dangerous.

Businesspeople tend to apply microeconomic reasoning to macroeconomic problems. Their opinions are often wrong and, in most cases, diametrically opposed to reality as a result.

Meanwhile, the City has a powerful vested interest in maintaining the myth that government depends upon it. That makes it an unreliable storyteller. 

And both routinely talk about money as though it were a thing rather than a relationship recorded through double-entry bookkeeping.

That combination is a recipe for wholly inappropriate comment on economic management on a disastrous scale.

If we want to understand government finance, we have to start somewhere else. We have to start by understanding how money actually works.
