Are bond markets pricing in debt sustainability risks?
Core argument: U.S. bond markets show no signs of a Greek-style solvency crisis, with breakeven inflation rates and credit default swap prices both remaining stable despite fiscal concerns.
There is very little evidence that fears of a Greek-style crisis are driving interest rates now. For example, if markets were really worried about U.S. solvency and the potential for the government to inflate the debt away, this should be reflected in measures that track inflation. But there has been, in fact, very little change in the “breakeven” inflation rate, a measure of long-term inflation expectations. Another indicator is the price of credit default swaps — insurance against a possible US default. These also haven’t moved much.
