Japanese yen steadies after suspected intervention 

The Japanese yen weakened slightly on Thursday after strengthening sharply in recent sessions. The pair rose 0.1% to 156.31 yen after falling as low as 155.38 yen earlier.

The yen’s sharp appreciation, which saw USDJPY slide from nearly 162 yen over the past week, sparked increased speculation that the Japanese government had once again intervened in currency markets.

Broader Asian currencies moved in a tight range, as risk appetite was dented by concerns over China. Comments from U.S. Republican presidential candidate Donald Trump, that Taiwan should pay the U.S. for defense supplies, also weighed on sentiment. 

The Australian dollar was an outlier, with rising 0.1% after data showed the country’s , increasing the chances of an interest rate hike by the Reserve Bank.
