In the US, the 4T on Fed's balance sheet means little. The paper purchased through QE is being held until maturity and then being extinguished. Compare to Europe. Dragi stated recently he will be reinvesting... IOW, the carried debt will NOT retire or extinguished. I pity the Euro currency.
Back to the US
No mis-direction there... you'd BETTER pay attention to (US and elsewhere) interest rates! Unlike the declining and eventually disappeared 4T debt on the feds balance sheet, the deficits created by the Washington morons won't expire or be retired in our lifetime, or our childrens lifetime, and require constant buyers for roll-over. This is why interest rate is crucially important. Alternatively, QE all over again, but with the short AND long term duration being bought. Don't you think that would make for some good times?
The 4T USFed balance sheet is less than 20% of the US deficit. The ECB and JCB do not compare. It's beyond stupid to think Yen is a "safe-haven" play. Still, I pity the Euro currency more.
