AKIPRESS.COM - Japan's top economic officials are scrambling to respond to the financial market turmoil unleashed by the U.S. presidential election, reports CNN.

The country's finance ministry and central bank were holding an emergency meeting Wednesday afternoon after wild trading in Japan's stock market and currency.

The benchmark Nikkei index plummeted more than 900 points – a drop of 5.4% – as Donald Trump took the lead in key battleground states in the U.S.

The Japanese yen, a currency that's seen as a safe haven in times of uncertainty, surged more than 2% against the dollar.

A strengthening yen is bad news for many Japanese companies and the economy. It hurts exporters by making goods produced in Japan more expensive overseas. And as imports get cheaper, it makes it much harder for Japan to tackle deflation, which has plagued the world's third biggest economy for decades.

The yen is still below the highs against the dollar it reached in the aftermath of Britain's vote in June to leave the European Union. But the emergency meeting suggests Japanese officials are worried it could climb further.
