As reviewed in this timeline from BBC news, the 2007-2008 global financial crisis began with the sub-prime mortgage collapse in the United States, but economic turmoil quickly spread to Europe and beyond as banks that had invested in mortgage-backed securities suffered serious losses. Similarly, the debt problems of Greece, Ireland, and Portugal since 2009 led to a decline in the value of the euro and have thrown the entire 17-country eurozone into crisis.
On Thursday stocks plunged on Wall Street; the Dow fell over 500 points in the biggest single day loss since 2008. Interestingly, most analysts attributed the selloff not primarily to concerns about the American economy, but to fears about the solvency of Italy and Spain–the third and fourth largest eurozone economies behind Germany and France. The threat of a “contagion” effect is highlighted in this explainer from CNN:
“…Anxieties over Italy’s economic future have led many to wonder what its default might mean for Europe and beyond, with the dreaded word ‘contagion’ on many lips. [Former IMF executive board member Domenico] Lombardi believes the current situation is serious. ‘If you affect Italy, you can really weaken the euro significantly,’ he says, describing it as the ‘weakest link’ among Europe’s big economies. Worse, he says, the European Union, the IMF and the European rescue fund do not have enough money to bail it out as they did smaller European economies — sparking a potential domino effect. So far the crisis has been limited to Greece, Ireland and Portugal, he said. ‘But of course if the crisis was to hit Italy, it would spread also to France, to the rest of the euro area, and of course you would have contagion to the U.S. through the banking system.’ The huge public debt held by the United States also would make it more vulnerable to speculators, he added.”
How Standard and Poor’s decision (announced late Friday) to downgrade the U.S. credit rating will affect the global economy is the subject of great speculation this weekend. Officials from the G-7 and G-20 groups of major economies are holding conference calls this weekend to plan for further turmoil in the financial markets.
Is there anything individual countries can do, in a globalized world, to limit the damage they may suffer from a possible global contagion, or are they and their citizens at the mercy of the world economy? Could protectionist trade practices and other tools of economic nationalism safeguard the U.S. or would this only make problems worse?
