CFTC data show hedge funds increased net short positions in yen futures and options to about 138,000 contracts in the week to June 30, the most bearish positioning since 2007. The yen fell to its weakest since 1986, slipping below 162 per dollar, fueling renewed expectations of Japanese FX intervention; Japan's finance minister reiterated authorities can intervene at any time and Tokyo deployed record-sized support in late April–May. Markets view a widening US–Japan rate gap as the main driver of yen pressure, and say recent BOJ rate hikes have not reversed the weakness.(金十数据)
