LONDON (Reuters) - The Japanese yen raced to its highest level in more than 16 months and the Swiss franc surged on Friday as the growing threat of a trade war prompted investors to take shelter in perceived low-yielding currencies.
With short positions in the yen at near record highs, according to weekly positioning data, thanks to years of using the Japanese yen as a funding currency to buy high yielders, markets braced for some unwinding of those bets.
"Trade wars, the spike in dollar funding costs and a tricky quarter end means that currency markets can become a bit messy going into next week," said Marc Ostwald, a global strategist at ADM Investor Services International in London.
The dollar fell to as low as 104.635 yen on Friday, the greenback's lowest level since November 2016. The dollar was last down 0.5 percent at 104.80 yen
