Data from the US CFTC showed that speculative net positioning in yen futures turned net long for the first time in 7 months, while USD/JPY moved rapidly into the ¥152 range. The move was driven by expectations of Bank of Japan rate hikes and the potential repatriation of overseas assets.
According to materials from the US Commodity Futures Trading Commission (CFTC), non-commercial net positioning in yen futures was net long by 10,796 contracts as of 8 September, reversing from a net short position the previous week. This was the first shift to a net long position since 24 February.
Alongside this change in positioning, leveraged traders nearly halved their bets on a weaker yen, while speculative foreign-exchange traders reduced their bets on a stronger dollar for the sixth consecutive week. USD/JPY fell to ¥152.89 on 8 September.
The yen's strength has been attributed to expectations that the Bank of Japan will accelerate the pace of rate hikes and the potential repatriation of overseas assets by Japanese investors. Attention will now focus on the Bank of Japan's next monetary policy decision and the Federal Reserve's stance, with yen appreciation pressures potentially intensifying depending on the direction of interest-rate differentials.
Over the longer term, the unwinding of yen carry trades and the repatriation of overseas assets could change the structure of the market, although some view the impact of policy decisions by the Ministry of Finance and the Bank of Japan as limited. Future developments are expected to depend on interest-rate trends in Japan and the US and the outcomes of their policy meetings.
