Will bond yields return to their previous lows?
Core argument: DeLong guesses bond rates will mean-revert by about 0.5 percentage points, plus whatever portion of the recent interest-rate rise is an overreaction to shifts in the fundamental flow-of-funds supply-demand balance.
What are the odds that bond rates are going to return to the 2010s normal? Low. But some mean-reversion is highly likely. How much? My guess is 0.5%-points, plus whatever in the recent interest-rate rise is an overreaction to shifts in the fundamental flow-of-funds supply-demand balance—but I run out of space here before I can even start analyzing that. Emerging market-rich, sovereign wealth fund, and exchange-reserve demand for US Treasuries continues to scale with the wealth of the world, or rather with the wealth of the world’s rich and the wealth and power of the world’s governments. I simply do not see the safe-asset shortage component of secular-stagnation low U.S. Treasury rates as being over.
