USD/JPY Holds Above 148.50 as BoJ Uncertainty Meets U.S. Policy Risks

The Japanese yen remained under pressure on Tuesday, with USD/JPY defending the 148.50 level after retreating from last week’s two-month peak. The move came as the Bank of Japan (BoJ) released its Summary of Opinions, highlighting uncertainty around the timing of potential interest rate hikes.

Policymakers reiterated that future increases will depend on sustained growth and inflation, leaving markets without a clear timeline. Traders interpreted the remarks as a sign of caution, which has undercut the yen’s appeal even as global risk sentiment improves.

The yen’s weakness is amplified by political uncertainty, with Japan’s ruling Liberal Democratic Party (LDP) leadership election set for October 4. If a dovish candidate emerges victorious, analysts warn the BoJ could delay its next policy tightening.

U.S. Policy and Market Expectations

Dollar moves also reflect shifting expectations for U.S. monetary policy. Following the August inflation report, markets are pricing in an 88% probability of a Federal Reserve rate cut in October and a 65% chance of another in December, according to the CME FedWatch Tool.

Meanwhile, U.S. fiscal uncertainty looms large. President Donald Trump is scheduled to meet congressional leaders on Monday to negotiate government funding. Without a deal, a shutdown could begin October 1, coinciding with new tariffs on trucks, pharmaceuticals, and other imports. Analysts warn the standoff could delay the September nonfarm payrolls report and other key releases, clouding market visibility.

Key U.S. factors shaping USD/JPY:

• 88% chance of Fed cut in October; 65% probability of December cut.
• Potential government shutdown October 1 if no funding agreement.
• New tariffs on select goods set to take effect alongside fiscal risk.

Outlook Hinges on Japan’s Politics

In Tokyo, traders are closely watching upcoming data and political developments. The August Retail Trade report will provide further clues on consumer strength, while the LDP leadership vote remains a pivotal risk event. A leadership shift toward a dovish policy stance could reinforce yen weakness, particularly if paired with ongoing BoJ caution.

Despite short-term volatility, analysts emphasize that the yen’s trajectory will hinge on the balance between U.S. easing expectations and Japan’s gradual policy normalization. For now, USD/JPY appears well supported above 148.50, though further gains could be capped if U.S. fiscal tensions intensify in October.
