Bernake still has his printing press in high gear. The dollar was down today. Many other central banks are also printing billions. The US debt is so high it can never be repaid without deflating the dollar. So why do people buy US Treasuries (the 30 year bond interest rate is down 4 basis points today)? You are guaranteed a loss if you buy the 30 year bond. Does anyone know what is going on in this crazy world?
