BNP Paribas expects the yen to stabilise as the BoJ tightens gradually. The call challenges the narrative of persistent pressure from rate differentials. The March BoJ meeting and wage talks are the next test for USD/JPY shorts.
BNP Paribas expects the Japanese yen to stabilise as the Bank of Japan continues tightening policy at a measured pace. The call challenges the prevailing market narrative that the yen will remain under pressure from wide rate differentials between Japan and the US. The bank's research note assumes the BoJ will deliver gradual rate hikes spaced across multiple meetings rather than rushing to normalise policy.
The simple read is that a slower tightening cycle helps the yen find a floor without triggering a sharp unwind of carry trades that have fueled yen weakness. The better market read is more specific: the stabilisation thesis relies on the BoJ raising the overnight call rate in small increments while the Federal Reserve holds rates steady. That combination compresses the two-year yield differential between US Treasuries and Japanese government bonds, reducing the incentive to short the yen.
BNP's note does not cite a price target. It signals that the worst of the yen's depreciation may be over once the market fully prices in the pace of BoJ action. The bank argues that the yen is already undervalued on a purchasing power parity basis. Any reduction in the real yield gap could trigger a repositioning.
The key mechanism is positioning. Hedge funds and asset managers have built large short yen positions through the USD/JPY pair, betting that the BoJ would lag the Fed. If the BoJ delivers a 25-basis-point hike in March and signals another move in the second half of the year, those shorts become vulnerable to a squeeze.
BNP's call aligns with recent COT data showing a slight uptick in long yen contracts among speculative traders. Short positions still dominate. For traders, the gradual tightening path reduces the risk of a sudden policy error that would roil currency markets. A faster BoJ cycle would risk pushing Japanese bond yields too high, hurting domestic banks and pension funds. A slower cycle keeps the yen weak but stabilises it, which is BNP's central scenario. Execution risk lies in the BoJ's communication. If Governor Ueda signals impatience with the pace of wage growth or inflation, the market could read a more aggressive path, sending the yen higher quickly.
USD/JPY traders now face a clear decision point: does the market price a BoJ hike in March and a hold in June, or does it expect more tightening than BNP assumes? The next BoJ meeting on March 19 is the immediate catalyst. If the board delivers no hike and removes language about gradual tightening, BNP's stabilisation thesis weakens. Inflation data for January and February, along with the spring wage negotiations outcome, will be the confirming or disconfirming signals.
A break below USD/JPY 148 would be the first test of the stabilisation idea. A move above 152 would break it, suggesting the market still doubts BoJ resolve. For now, BNP Paribas offers a framework: gradual hikes, steady Fed, and a yen that holds a range rather than trending weaker. The trade is to buy yen on dips against the dollar, not to chase the breakout.
