Speculative Bets on Japanese Yen Turn Bullish, CFTC Data Shows

Speculative investors turned net bullish on the Japanese yen for the first time since February, a significant reversal driven by expectations that the Bank of Japan may accelerate its monetary policy tightening. The latest positioning data reflects a dramatic shift in sentiment for the currency, which has rallied sharply in recent weeks.
A Major Shift in Positioning
Data from the Commodity Futures Trading Commission (CFTC) released late Friday showed that net non-commercial positions in yen futures reached 10,796 long contracts in the week ending September 8. This marks a stark turnaround from the previous week, which saw net short positions of 92,227 contracts, according to a Reuters report.
The swing of more than 100,000 contracts in a single week represents the first overall net long speculative position since February 24. This change indicates that traders are no longer betting on further yen weakness but are now positioned for additional gains.
Drivers of the Yen's Rebound
The shift in futures positioning follows a strong performance for the yen, which hit 152.89 against the U.S. dollar on September 8 — its strongest level since February 17. The rally has been fueled by growing expectations for a more aggressive rate-hike schedule from the Bank of Japan.
AdMarket sentiment has also been bolstered by speculation that Japanese investors could begin to repatriate assets held overseas, a move that would increase demand for the yen. These factors have provided a key catalyst for the currency's recent turnaround.
Context: From Multi-Decade Lows
This renewed optimism comes after a prolonged period of weakness for the Japanese currency. The yen had fallen to a four-decade low of 163.99 per dollar in July amid concerns that the Bank of Japan was lagging behind other major central banks in tightening monetary policy.
Earlier losses had been exacerbated by dovish fiscal policies and eventually prompted intervention from Tokyo and Washington to support the currency. The latest CFTC data confirms that speculative sentiment has now decisively shifted, aligning with the yen's recent recovery.
