Euro Steadies Against Yen as ECB and BoJ Both Signal September Rate Hikes

The euro traded flat against the Japanese yen on Tuesday, as investors weighed expectations that both the European Central Bank (ECB) and the Bank of Japan (BoJ) are likely to raise interest rates at their respective September meetings.

Why the Euro Is Holding Steady

The EUR/JPY pair remained range-bound, with the shared currency failing to gain momentum despite a broadly softer US dollar. Market participants are cautious ahead of key central bank decisions, with the ECB widely expected to deliver a 25-basis-point hike in September, while the BoJ is also seen tightening policy after recent comments from officials.

The euro’s inability to push higher against the yen reflects a balance of forces: the ECB’s tightening cycle is well telegraphed, but the yen has found support from expectations that the BoJ will adjust its yield curve control or raise rates to counter inflation. This leaves the cross currency in a tight range, with traders looking for fresh catalysts.

ECB and BoJ Divergence Narrowing

The ECB has been on a path of steady rate increases to combat elevated inflation in the eurozone, which remains above the 2% target. As of August 2025, the deposit rate stands at 3.75%, and markets have priced in a further hike in September. However, recent economic data from the eurozone has shown signs of softening, which could prompt the ECB to adopt a more cautious tone.

Meanwhile, the BoJ has been an outlier among major central banks, maintaining ultra-loose policy for years. But with core inflation in Japan now consistently above the BoJ’s 2% target, pressure is mounting for a policy shift. Governor Kazuo Ueda has hinted that the central bank could act if inflation expectations remain anchored, and a move in September is seen as increasingly likely.

Implications for Traders and Investors

For forex traders, the narrowing policy divergence between the ECB and the BoJ reduces the interest rate differential that had favored the euro. This could keep EUR/JPY capped in the near term, with support seen around the 160.00 level and resistance near 163.00. A surprise from either central bank could trigger volatility, but the current market pricing suggests a relatively balanced outcome.

Investors with exposure to Japanese assets or European equities should monitor the upcoming decisions closely, as a hawkish BoJ could strengthen the yen and impact carry trades, while a dovish ECB could weigh on the euro. The September meetings are pivotal for the medium-term direction of the pair.

Conclusion

The euro’s flat performance against the yen underscores the market’s cautious stance ahead of the September central bank meetings. With both the ECB and BoJ expected to raise rates, the focus will be on the accompanying guidance and economic projections. A clearer picture of policy paths will likely determine the next sustained move in EUR/JPY.
