For Britain, a Brexit could me a currency crisis for the pound, a massive increase in the country’s trade deficit, and big ballooning of the country’s debt, not to mention a likely recession.
Across, though, if Britain were to leave the EU, it is unlikely it would be Brexigeddon for U.S. economy. The U.K. is the third largest generator of revenue for the S&P 500 among our trading partners, according to data provider FactSet. But it’s still pretty small. U.K. sales make up just 2.9% of the overall revenue of the S&P 500. Still, some Fortune 500 companies may not feel so proper if Britain leaves the EU.
