From 2001-07, he argues, the dollar underwent a long, steady decline against the euro, tacitly encouraged by U.S. monetary authorities. In response to the dollar’s decline, investors diverted capital into inflation hedges, notably real estate, leading to the subprime bubble. By mid-2007, the real-estate bubble had burst. In response, the Fed reduced short-term interest rates rapidly, which lowered the dollar further. The subprime crisis was severe, but with looser money, the economy appeared to stabilize in the second quarter of 2008.
Then, in summer 2008, the Fed committed what Mr. Mundell calls one of the worst mistakes in its history: In the middle of the subprime crunch””exacerbated by mark-to-market accounting rules that forced financial companies to cover short-term losses””the central bank paused in lowering the federal funds rate. In response, the dollar soared 30% against the euro in a matter of weeks. Dollar scarcity broke the economy’s back, causing a serious economic contraction and crippling financial crisis.
In March 2009, the Fed woke up and enacted QE1, lowering the dollar against the euro, and signs of recovery soon appeared. But in November 2009, QE1 ended and the dollar soared against the euro once again, pushing the U.S. economy back toward recession.
My favorite line is this piece:
“His economic predictions carry great weight because, unlike most economists of his generation, he is often right.”
