Although my book-in-progress is called The Economic Consequences of the Pandemic, a lot of it will deal with changes that were already underway, and have only been accelerated by the pandemic. This was also true of Keynes’ Economic Consequences of the Peace. The economic order destroyed by the Great War was already breaking down, as was discussed for example, in Dangerfield’s Strange Death of Liberal England.

Amid all the strange, alarming and exciting things that have happened lately, the fact that real long-term (30-year) interest rates have fallen below zero has been largely overlooked. Yet this is the end of capitalism, at least as it has traditionally been understood. Interest is the pure form of return to capital, excluding any return to monopoly power, corporate control, managerial skills or compensation for risk.

If there is no real return to capital, then then there is no capitalism. In case it isn’t obvious, I’ll make the point in subsequent posts that there is no reason to expect the system that replaces capitalism (I’ll call it plutocracy for the moment) to be an improvement.

But first let’s look at the real 30-year bond rate. The US Treasury is currently offering an inflation-protected 30 year bond at a rate of -0.3 per cent. That is, if you buy the bond at say, age 35, you can get your money back, less a 10 per cent reduction in real value, when you are 65. This rate has fallen from 2 per cent, when the bond was introduced in 2010, and started declining sharply in late 2018, before the pandemic, and while the Federal funds rate was rising.

In thinking about the future of the economic system, interest rates on 30-year bonds are much more significant than the ‘cash’ rates set by central banks, such as the Federal Funds rate, which have been at or near zero ever since the GFC, or the short-term market rates they influence. These rates aren’t critical in evaluating long-term investments.

The central idea of capitalism is, as the name implies, that of capital. Capital is accumulated through saving, then invested in machines, buildings and other capital assets to be used by workers in producing goods and services. Part of the value of those goods and services is paid out as wages, and the rest is returned to capital, as interest on loans and bonds or as profits for shareholders. Some of the return to capital is saved and reinvested, allowing growth to continue indefinitely. Workers, on this account, can become capitalists too, by saving and investing some of their wages. At a minimum, they should be able to save enough, while working, to finance a decent standard of living in retirement.

But what happens if there is no return to capital? The collapse of interest rates on government means that’s already true for anyone who wants a secure investment. And the situation isn’t any different for the two remaining AAA-rated corporate borrowers, Microsoft and Johnson and Johnson. Microsoft is currently offering a rate of 2.5 per cent on 30-year bonds, and has exchanged lots of outstanding debt for new bonds at that rate (paying a 40 per cent premium for higher-interest bonds). That’s a real return of 0.5 per cent if you assume that the Fed sticks to its current 2 per cent target and hits it on average. (There’s a lot more room for inflation to surprise on the upside, in my view). If you allow a 15 per cent risk that Microsoft will go bankrupt some time before 2050, the expected real return falls to zero.

To complete the picture of returns to capital, we need to look at stock markets and corporate profits. That’ll be the subject of another post.

As with most really neat sayings, the original (with billions, instead of trillions) is misattributed, in this case to the late Senator Everett Dirksen, a conservative Republican who nonetheless helped to write the 1964 Civil Rights Act. The saying can be traced back to an unsigned New York Times article in 1938, which said ““Well, now, about this new budget. It’s a billion here and a billion there, and by and by it begins to mount up into money”. This in turn improved on earlier versions going back at least to 1917
US GDP today (Over $20 trillion) is around 250 times as high, in dollar terms, as it was in 1938, so replacing billions with trillions isn’t much of a stretch.

With that in mind, what should we think about the $2.4 trillion pandemic relief package, and the likelihood of huge demands for public expenditure stretching well into the future? And how much of this analysis is applicable to the world as a whole, where large scale government responses have been the norm rather than the exception.

The simplest way to finance a public expenditure program is to “print money”, or, more usually in a modern economy, to create monetary reserves that can be used to buy government bonds or other financial assets (so-called “quantitative easing”). That in turn means the government can spend, or lend, money without a net increase in the debt owed to the public (or to overseas bondholders). The magnitude can be measured by the monetary base.

The scope to expand the monetary base is limited, but more than enough to cover the immediate needs of the pandemic response. The response to the GFC led to an expansions of the monetary base from $1 trillion to $4 trillion between 2009 and 2015, after which it was wound back by about $1 trillion. It’s grown by nearly $2 trillion (about 10 per cent of GDP) in response to the pandemic, and more is likely to come

The ultimate constraint on money creation is inflation. That hasn’t been a problem lately and (as I’ll argue in more detail later) the world is in need of a fair bit of inflation, probably at an annual rate of about 4 per cent for the foreseeable future. It’s unclear how much expansion of the monetary base would generate this outcome, while avoiding the risk of a resurgence of inflation like that of the 1970s. But looking at the scale of the response that’s going to be needed for a meaningful Green New Deal (I’d estimate at least 5 per cent of GDP every year for the next decade at least), the amount that can be financed through money creation will be nowhere near enough. Substantial reductions in private consumption and investment will be needed to make room for the required public expenditure, and that can only be achieved through a combination of taxation and debt. More on this, and on global response soon, I hope.
