"That commitment by the central bank to demonetise the public debt in the future has to be credible today"

Willem Buiter with a new post in the FT:

"Monetise public debt and deficits

November 22, 2008

The diminished role of monetary policy

The paralysis of financial intermediation today means that monetary policy (cuts in the official policy rates) have become largely ineffective in stimulating demand. Such cuts now appear to have little if any effect on either the marginal cost or the availability of external funds to non-financial enterprises and households. For individual open economies, the exchange rate provides a mechanism for stealing aggregate demand from the neighbours. If most of the neighbours are also in a situation of deficient aggregate demand, this redistribution of global effective demand - which is all that changes in exchange rates accomplish - robs Peter to pay Paul and is not part of a global solution at all.

The continuing importance of liquidity policy

Central banks are doing the right thing by massively expanding their balance sheets to put as much liquidity into the economy as possible. The balance sheets of the Fed and of the Bank of England have doubled since the crisis started and the balance sheet of the Eurosystem has expanded by about 50 percent. This has been accomplished through open market operations of various kinds, through which the central banks have increased their holdings of private securities by expanding the monetary base, mainly by increasing bank reserves with the central bank and other central bank loans.

Central banks will have to continue to do this. The private financial sector has to deleverage massively, but would (with credit markets and wholesale financial markets closed for business) do so in an unnecessarily destructive way if left to its own devices. The household sectors in the US, the UK and a number of other European countries have to deleverage (start saving seriously) on a significant scale. Left to its own devices, the short-run Keynesian aggregate demand fall-out from a necessary reconstruction of household financial wealth could be disastrous. So the public sectorhas to leverage up (borrow) at the same time the household sector is forced to deleverage.

This process of monetisation of private sector financial instruments can continue almost indefinitely. It is restricted only by the total stock of private financial instruments outstanding and by the central bank’s willingness to add private securities with higher and higher degrees of default risk attached to them to its balance sheet.

Read it all. I don't paraphrase Buiter. Here's my comment:

“That commitment by the central bank to demonetise the public debt in the future has to be credible today, lest there be an immediate increase in long-term nominal interest rates when the central bank monetises public debt and deficits, due to higher long-term inflation expectations. That commitment by the government to run sufficiently large primary budget surpluses (budget surpluses excluding interest) has to be credible today, lest there be an immediate increase in sovereign default risk premia as the government increases its borrowing.

“There can be no doubt that, if public spending is not cut, future taxes have to be higher if the government borrows more now and permanent monetary financing is not an option. It is also virtually certain that tax rates will have to be higher. The government will get some help from the positive effect on the main tax bases (income, profits, consumption) of the expansionary fiscal measures, but not enough to prevent the need for future higher tax rates (taxes as fractions of the relevant tax bases).”

I agree with this, since, although I don’t like it, I believe that to combat the fear and aversion to risk ( Which, from my point of view, explains bond spreads, as a flight to safety of such magnitude as we now see entails an even greater flight from any risk ), we are going to have to cut taxes and have a stimulus. The fear from investors is that we will overprint money or default, so we need to assure everyone that we will raise taxes or cut expenses in the future.

However, even if we put this in legislation, like Britain and Japan have talked about, raising the problem of people saving during a downturn to anticipate loss of revenue in the future ( Although, as Peston says, you can lower the VAT with a cutoff date, prodding people to spend now. We can’t ), will anybody believe it. I mean, in the U.S., we haven’t shown a very great desire to confront these types of hard choices recently.

So, I agree we should say this and mean it, but, aren’t we basically stuck? In other words, we have to follow this plan whatever investors believe about us, and deal with the fallout as best we can in the future, because the other options are even more dreadful?
