Yen Nears 160 Mark Against Dollar Again, What Signals Is BOJ Governor Kazuo Ueda Sending?

The Bank of Japan’s interest rate decision passed with a 6-3 vote, marking the most divided outcome since Kazuo Ueda became Governor and the widest internal split within the BoJ since 2016; all three dissenting members proposed raising interest rates to 1.0%.

The spike in oil prices caused by the U.S.-Iran conflict has become a key anchoring factor for interest rate adjustments by global central banks. In its quarterly outlook report, the BoJ significantly raised its median core CPI forecast for fiscal 2026 to 2.8% from the 1.9% projected in January, while slashing its real GDP growth forecast for fiscal 2026 from 1.0% to 0.5%.

On the data front, Japan’s core CPI rose 1.8% year-on-year in March, accelerating for the first time in five months. The core-core CPI, which excludes food and energy, rose 2.4% year-on-year, remaining above the central bank’s 2% target. The services producer price index rose 1.25% month-on-month—the largest single-month increase in nearly 36 years—indicating that inflation is shifting from energy imports to the domestic service sector.

Kazuo Ueda will explain the rationale for keeping interest rates unchanged at a press conference this afternoon. The market maintains a highly cautious historical reference regarding him: in April 2024, after also holding rates steady, Ueda’s remarks on the yen were interpreted as dovish, leading to a plunge in the currency and subsequent government intervention days later.

In this resolution, Ueda delivered a sufficiently hawkish signal to soothe the market while preserving room for a rate hike in June.

Ueda stated that the BoJ will continue to raise interest rates based on economic conditions, warning that upside risks to prices have outweighed downside risks to the economy; furthermore, he noted that overall financial conditions remain accommodative.

From the perspective of exchange rate trends, USD/JPY has gained more than 2% cumulatively since the onset of the conflict in the Middle East, remaining firmly locked within the 158 to 160 range.

Expectations of intervention by Japanese authorities have deterred yen shorts from crossing the line, while the Finance Minister warned today of 'taking decisive action against future foreign exchange fluctuations.' This is expected to keep the yen relatively firm in the near term and over the next several days.

At the same time, fundamental pressures such as high oil prices and a deteriorating trade balance are contributing to gradual yen weakness, providing sustained downward momentum. Kei Fujimoto, an economist at Sumitomo Mitsui Trust Asset Management, previously pointed out that the current yen weakness is driven more by economic fundamentals than simple speculative factors; thus, the marginal effect of currency intervention may be limited.

Commerzbank analyst Volkmar Baur stated that if the Bank of Japan keeps interest rates unchanged and fails to release a clear signal for a June hike, 'intervention warnings from the Ministry of Finance alone may no longer be of much help,' and USD/JPY could potentially break through the 160 mark.

Institutional forecasts show that PineBridge Investments expects the Bank of Japan to raise interest rates once more within the next one to two quarters, gradually pushing the policy rate toward a neutral level of 1%. Additionally, a weakening outlook for the US dollar may provide passive support for the yen toward the end of the year.

In the short term, the June rate hike window remains the market's primary focus. At the same time, the conflict between slowing economic growth and soaring inflation expectations dictates that for every hawkish signal Kazuo Ueda releases, he must simultaneously leave some leeway for the economic growth outlook.
