While such comments are broadly consistent with previous communication, the emphasis on FX comes at a time when exchange rate volatility is increasingly feeding into domestic inflation dynamics.A key shift highlighted by Ueda is the changing behaviour of firms. As companies become more willing to raise wages and pass on higher costs, fluctuations in the yen are having a more direct and amplified impact on prices. This suggests that FX is no longer just influencing import costs at the margin, but is increasingly shaping underlying inflation through expectations and pricing behaviour.Ueda also noted that currency movements can affect inflation expectations, reinforcing the idea that exchange rates are becoming embedded in the Bank of Japan’s policy framework. The central bank will assess how FX developments influence the likelihood of achieving its growth and inflation forecasts, as well as the balance of risks around its 2% target.Importantly, the governor stopped short of issuing any direct warning about excessive currency moves or signalling concern about specific levels, meaning the remarks do not constitute formal verbal intervention. However, the tone suggests a subtle shift toward greater sensitivity to yen weakness, particularly given its inflationary implications.Ueda added that long-term interest rates are moving in line with market expectations for growth, inflation and policy, and indicated that a gradual and appropriate pace of short-term rate hikes should help maintain stability across the yield curve.For markets, the takeaway is nuanced. While not an explicit attempt to influence the currency, the comments reinforce that FX is now firmly part of the BoJ’s reaction function. That alone can have a stabilising effect on the yen, particularly in an environment where investors are testing central bank tolerance for currency-driven inflation pressures.
