Japanese Yen dips as US inflation surprise lifts Dollar, hawkish BoJ anchors JPY

• US inflation accelerates to 3.8% in April, above market expectations, supporting the US Dollar.
• Markets scale back Fed rate cut expectations following the stronger CPI report.
• The Japanese Yen remains supported by intervention risks and BoJ rate hike expectations.

USD/JPY trades around 157.65 on Tuesday at the time of writing, up 0.30% on the day. The pair benefits from renewed strength in the US Dollar (USD) after stronger-than-expected inflation data from the United States (US), while the Japanese Yen (JPY) limits gains amid persistent intervention concerns from Japanese authorities.

The Bureau of Labor Statistics (BLS) reported that inflation, as measured by the Consumer Price Index (CPI), accelerated to 3.8% YoY in April from 3.3% previously, above market expectations of 3.7%. On a monthly basis, the CPI rose 0.6%, in line with forecasts. Core inflation, which excludes volatile food and energy prices, increased to 2.8% YoY from 2.6% previously, also exceeding the 2.7% consensus.

The report also noted that energy prices rose 3.8% in April, accounting for more than 40% of the monthly increase in the overall index. Shelter and food costs also continued to rise, reinforcing concerns about persistent inflationary pressures in the US.

Meanwhile, weekly ADP data showed that US private employers added an average of 33K jobs per week over the four weeks ending April 25, signaling a modest improvement in labor market momentum.

Following the release, the US Dollar Index (DXY) advances toward 98.30, while US Treasury yields move higher. Investors now assess that the Federal Reserve (Fed) may need to keep interest rates elevated for longer in order to contain inflationary pressures. According to the CME FedWatch tool, the chance of a rate hike by the December meeting increased to 29.6% after the CPI release, up from 21.5% in the previous day.

The US Dollar is also benefiting from safe-haven demand. Geopolitical tensions in the Middle East remain elevated after US President Donald Trump stated that the US-Iran ceasefire was “on massive life support,” reviving concerns over a possible resumption of military operations.

On the Japanese side, the JPY remains supported by intervention speculation. US Treasury Secretary Scott Bessent recently confirmed that the United States and Japan had taken certain joint actions to address excessive volatility in currency markets. Investors therefore remain cautious about the risk of another intervention should USD/JPY approach the 160.00 area again.

Expectations of monetary tightening from the Bank of Japan (BoJ) are also supporting the Japanese currency. The Summary of Opinions from the central bank’s April meeting showed that some members believe another rate hike could come soon, while markets continue to price in an additional increase in Japanese interest rates in the coming months.
