The Dow's 'scary' collapse: 6 theories - The Week 1. Wall Street hates the debt deal The plunge Thursday capped a 10-day slump, says Stephen Gandel at TIME, that started when it became clear that Washington was close to a debt deal. That's because the deal cuts spending precisely when the economy needs government to spend more. And the savings comes largely from gutting programs that help the poor, increasing income inequality. Struggling families spend every dime they get, boosting the economy. The rich have so much already that they put any "extra wealth" into savings, where it does little to stimulate the economy. 2. European debt is frightening investors The European Central Bank is trying to reassure markets, says Graham Bowley at The New York Times, but it "ended up spooking investors." The bank bought up bonds from small European countries as a show of support, but it left out Italy and Spain, "whose mounting troubles have come into the spotlight." Investors took this "as a sign that the recent rescue packages by Europe could soon be overwhelmed by the huge debt burdens in those two countries" — and they panicked 3. Investors are freaked out about a double-dip recession There's no great mystery — the markets are pricing in "the growing risk of a double dip" recession, says Allahpundit at Hot Air. We've just been slammed by a string of devastating economic reports showing that, among other things, the economy has essentially stopped growing, unemployment isn't improving, and manufacturing orders are down. The Obama administration isn't creating jobs, but it's scaring investors with the threat of new taxes and regulations. Add it all up and you get "total fear." 4. Republicans are blocking attempts to help the economy President Obama has no shortage of ideas to put Americans back to work, says Steve Benen at Washington Monthly. But the GOP has been overcome with "madness," and it's blocking every proposal that might actually help. "This is partly due to their radical ideology, partly due to their reflexive opposition to anything the president wants, and perhaps motivated by the belief that economic suffering should be encouraged in the hopes that it will make President Obama easier to defeat next November." 5. It's finally dawning on people just how bleak things are "Whatever weak recovery we might have hoped for," says Ezra Klein at The Washington Post, "is being hindered by global commodity prices, consumer deleveraging, fears of flagging demand in emerging markets, earthquakes in Asia, and much more." So where will the recovery come from? "As one hopeful hypothesis after another is dashed, the markets are beginning to panic." 6. The media is fueling market panic Financial analysts chalked up the sell-off, which wiped out Wall Street's 2011 gains, to investor fear, says Dylan Stableford at Yahoo! Finance. But it's also possible that wall-to-wall coverage of the "historic drop" on broadcast networks and cable news could have fueled the panic. Still, some experts doubt the TV chatter had much impact. "A huge chunk of volume — and hence momentum — is now driven by machines, computers and algorithmic trading," says Dan Gross, economics editor at Yahoo! Finance. "And the computers definitely aren't watching cable news."
