Explain how the "euro crisis" could potentially affect the following:

1.Exports from the United States
2. Supply chains of U.S. manufacturers.
3. U.S. banks

1. U.S exports could suffer as European consumers reduce spending. Although foreign trade is a relatively small part of U.S. gross domestic product, and only a small share of this trade is with Europe, U.S. exports have accounted for over 40% of the growth of GDP since the end of the recession in 2009.
2. Some U.S. manufacturers rely on European companies for components in their manufacturing, and a slowdown of European economies could reduce the amount of available components these firms use in the manufacturing of their products.
3. At the end of 2011, U.S. banks held over $650 billion worth of euro-zone debt, and if the euro crisis resulted in a decline in the value of the euro relative to the dollar, the value of this debt would be reduced.
