Dollar hits 8-week high against yen as Fed meets

London

The yen, which gains in times of crisis because Japan is the world's largest creditor nation and benefits from speculation about repatriation of Japanese money from overseas, also slid to a 21-month low against the euro.

Another safe haven, the Swiss franc, hit a multi-year low against the euro and analysts said this trend would remain as long as the US continues to favour a diplomatic solution to the North Korean crisis.
