The EU debt crisis and us

"Sovereign debt panic" finally struck last week, causing severe one-day drops in stock markets from New York to London to Toronto on Thursday. The epicentre of the crisis is Greece, in danger of defaulting on its debt payments to worldwide holders of its government bonds, or sovereign debt. The world is awash in potentially unsustainable debt, and the U.S. looms largest. President Barack Obama just tabled a budget that projects a doubling in America's national debt, to $28 trillion (U.S.), by decade's end. That's twice the size of the U.S. economy. Yet it's the EU who is threatening the wealth of all of us. If Greece defaults on its debts, and it's followed by Spain and Portugal and possibly Ireland and Italy as well, then the collapse of Lehman Brothers in 2008 will seem like a mere blip. It isn't so much the risk of default by these countries themselves that is spooking the markets at the moment, but the possibility that a still-skittish financial system will succumb to
another fear-driven contagion.
Normally Greece would simply devalue the drachma, or allow the markets to do it for them, and that adjustment would rebalance the economy and eventually make it more competitive, while also raising the value of foreign liabilities and making the people poorer. But that can't happen, because Greece is part of the monetary union, and the euro is held up by Germany's strength. There's talk of Greece leaving the euro, or being kicked out, but that would just make matters worse: outside the euro Greece would go into a downward spiral, dramatically increasing the value of its euro-denominated debts and creating hyper-inflation. While it's hard to imagine any of these countries' governments defaulting on their debts, restoring their budget balances is going to hold back their economic growth for a long time and lead to higher long-term government interest rates around the world.
