For more than 2 months, Treasury Inflation-Indexed Notes maturing within 2 years have been selling at prices that apparently mean their yields are negative (e.g. see here and here). This isn’t the first time people have apparently paid a government to hold their money, but I can’t think of a previous case where yields reached -1 percent.
What can cause such a perverse situation? An expectation that the CPI would overstate inflation by as much as 1 percent would mean appearances are misleading and investors do expect to make money on those notes. I could make a case for that by focusing on the way that the CPI’s reliance on rents to measure housing costs hides the effects of dropping home prices. But most evidence about people’s inflation expectations (e.g. the University of Michigan Inflation Expectation report) say they expect more inflation than what can be inferred from the Treasury Inflation-Indexed Notes about expected CPI change.
So I’m inclined to conclude that we’re seeing investors paying abnormally large amounts in order to get liquidity, and probably plan to redeploy those assets somewhere else within a few months. If we see a big financial crisis soon, that strategy may pay off. But having people prepare for financial crises tends to reduce their magnitude, so I’m skeptical and am short t-bond futures.
