The Bank of Japan (BOJ) is closely monitoring movements in the yen, with Governor Kazuo Ueda indicating that currency weakness and its impact on import costs could play a key role in shaping monetary policy decisions in the months ahead, according to Reuters.
The Japanese currency has come under renewed pressure, sliding past the psychologically significant 160 mark against the U.S. dollar—its weakest level since July 2024. The sharp depreciation has heightened concerns among policymakers and prompted verbal intervention warnings from Japan’s top currency official.
Ueda emphasised that while the central bank does not directly target exchange rates, fluctuations in the currency remain a critical factor influencing economic activity and price trends. A weaker yen raises the cost of imports, particularly energy and raw materials, thereby feeding into domestic inflation—an issue that has gained prominence in Japan’s evolving economic landscape, Reuters said.
The BOJ chief noted that the pass-through of currency movements into inflation has become more pronounced than in the past. This is largely due to a shift in corporate behaviour, with firms increasingly willing to raise prices and wages after decades of deflationary pressures.
This changing dynamic requires added importance to exchange rate trends when assessing the likelihood of achieving the central bank’s growth and inflation forecasts. Policymakers are therefore expected to carefully evaluate how sustained yen weakness could influence the broader economic outlook and price stability.
In March, the BOJ kept its short-term interest rate unchanged at 0.75% but maintained a tightening bias. The central bank also flagged risks from rising oil prices, driven in part by ongoing geopolitical tensions in the Middle East, which could further stoke inflationary pressures.
Investor concerns that the BOJ may be lagging in addressing inflation risks are already showing in the bond market. Japanese government bond yields moved higher last week amid speculation that the central bank may need to act more decisively.
Ueda also signalled that long-term interest rates would remain stable if adjustments to the short-term policy rate are carried out at an appropriate pace. However, he cautioned that failure to act in time could lead to an overshoot in inflation, which in turn might trigger a sharper-than-desired rise in long-term yields, Reuters reported.
Overall, the BOJ appears to be navigating a delicate balance—supporting economic recovery while remaining alert to inflation risks exacerbated by currency weakness. With the yen under pressure and global uncertainties persisting, the path of Japan’s monetary policy is likely to remain closely tied to developments in foreign exchange markets.
