In the past year, the US dollar has gained 20% in trade-weighted terms (against a basket of trading partners' currencies). "Moves of this magnitude usually catch someone out," says The Economist. This time it's likely to be emerging markets. "Loose US monetary policy has been exported to emerging markets" in recent years, says Longview Economics.
A weak dollar and low interest rates sent global investors into riskier assets, such as emerging markets, seeking higher returns. But a stronger dollar, and the higher rates that go with it now that the US Federal Reserve plans to tighten monetary policy, means money will head back to America.
A day of reckoning
It's mainly down to Asian and Latin American companies, says Ambrose Evans-Pritchard in The Daily Telegraph.

That suggests a further squeeze on Chinese growth,which will hit the rest of the region. And the yuan's peg against the dollar "isn't guaranteed to hold", says The Economist. So the pain could be made worse by a falling yuan.
These countries can't count on export earnings offsetting higher dollar costs many emerging-market exporters trade not only with America, but also with other countries. Also, "whole economies, rather than just the corporate sector, look short of dollars".
