The US Federal Reserve has announced its long-awaited renewal of quantitative easing (cutely labelled QE2). It’s $600 billion of new money to buy US Treasury notes with an average duration of five years, along with recycling of some money from the mortgage bailouts, also into T-note purchases. That sounds like a lot, but the reaction from Brad DeLong (endorsed by Paul Krugman) has been a big yawn. With the five-year bond rate at just over 1 per cent, the amount the private sector would demand to hold these bonds (that is, the annual interest payment) is about $7 billion, which is rounding error in the context of the current crisis.

I had been thinking that the Fed might take the much riskier (and politically trickier) step of buying corporate bonds. That would seem more likely to promote investment, but would obviously involve a good deal of winner-picking, with the associated potential for (real or perceived) corruption.

But what is really needed here is fiscal stimulus focused on job creation, combined with a long-term plan for fiscal consolidation (that is, higher taxes and/or lower expenditure). Instead, what the US appears likely to get is a permanent tax cut for the rich, partly offset by lots of job-destroying nickel-and-dime cuts in current expenditure. Many of these cuts will prove to be counterproductive or unsustainable in the long run.
