With or without the eurozone, U.S. interest rates would still be trading very close to historic lows.
We are in total disagreement on this matter. New purchases of treasuries at this level are mostly defensive in nature. Now we have the credit rating downgrade? There's no confidence the U.S. government is making the right moves to fix our economy. The rub here is even if things start to improve with our economy liquidity needs to be aggressively withdrawn from the system before inflation rears its nasty head.
The only thing the U.S. treasury market has going for it is its liquidity.
