U.S. Economic Double-Dip Is Coming
The most important cause of this is the lagged effect of the stagnant (slightly contracting) money supply numbers during the latest year. For some time, this was masked by a decline in money demand (a decline in money demand has a similar effect as an increase in money supply), but now that pessimism is increasing the decline in money demand has halted and perhaps started to reverse.
The expectation of significant tax increases in January 2011 as the Bush tax cuts expire is another key factor behind the weakening economy.
The fact that Treasury yields continue to drop despite the horrible fiscal situation of the U.S. government is a sign that money demand is increasing as many investors perceive them to be as safe as money.
