As 2009 opened, three weeks before Barack Obama took office, the Dow Jones Industrial Average closed at 9034 on January 2, its highest level since the autumn panic. Yesterday the Dow fell another 4.24% to 6763, for an overall decline of 25% in two months and to its lowest level since 1997. The dismaying message here is that President Obama's policies have become part of the economy's problem.

Americans have welcomed the Obama era in the same spirit of hope the President campaigned on. But after five weeks in office, it's become clear that Mr. Obama's policies are slowing, if not stopping, what would otherwise be the normal process of economic recovery. From punishing business to squandering scarce national public resources, Team Obama is creating more uncertainty and less confidence -- and thus a longer period of recession or subpar growth.

The Democrats who now run Washington don't want to hear this, because they benefit from blaming all bad economic news on President Bush. And Mr. Obama has inherited an unusual recession deepened by credit problems, both of which will take time to climb out of. But it's also true that the economy has fallen far enough, and long enough, that much of the excess that led to recession is being worked off. Already 15 months old, the current recession will soon match the average length -- and average job loss -- of the last three postwar downturns. What goes down will come up -- unless destructive policies interfere with the sources of potential recovery.

And those sources have been forming for some time. The prices of oil and other commodities have fallen by two-thirds since their 2008 summer peak, which has the effect of a major tax cut. The world is awash in liquidity, thanks to monetary ease by the Federal Reserve and other central banks. Monetary policy operates with a lag, but last year's easing will eventually stir economic activity.

Housing prices have fallen 27% from their Case-Shiller peak, or some two-thirds of the way back to their historical trend. While still high, credit spreads are far from their peaks during the panic, and corporate borrowers are again able to tap the credit markets. As equities were signaling with their late 2008 rally and January top, growth should under normal circumstances begin to appear in the second half of this year.
