I think his old employers and the other bankers told everyone to short their stock back in late Feb as well.
The PRC is totally dedicated to being an export nation. The last thing they want is a strong currency. The USA has a bond market and eventhough the Fed can buy some, it is dwarfed by the size of this market and the world debt market in general. Notice the 10-year creeping up to 3.85%. If this continues, it will decimate the US housing market and it will slow the govt spending severly. Nt sure about this, but I dont think a senior/world currency has ever managed to go into hyperinflation.
