Modest US Dollar weakness leaves Japanese Yen little changed

Between 157.00 and 158.00, USD/JPY remains rangebound with no clear directional bias.

Tokyo remains committed to supporting the Yen, Finance Minister Katayama reaffirmed on Monday.

Ahead of Tuesday's US midterm elections, the US Dollar continues to trade on the defensive.

Friday's decision to leave monetary policy unchanged, alongside uncertainty from the Bank of Japan (BoJ) over the timing of its next interest rate rise, has left USD/JPY trading within its established range around 157.00. The Japanese Yen (JPY) remains without direction on Monday, failing to capitalise on modest US Dollar (USD) weakness as markets prepare for the US midterm elections.

Tokyo stands ready to act should currency market moves become disorderly, Japanese Finance Minister Satsuki Katayama reaffirmed earlier on Monday. She also recalled the agreement with the US to curb excessive JPY weakness. Her remarks have nevertheless had little effect on the Yen.

The Bank of Japan held its benchmark interest rates at 1.25% on Friday, in line with widespread expectations. However, Governor Ueda made further rate rises conditional on developments in FX, IA and the Middle East conflict. His press release and the policy decision prompted modest JPY losses, as doubts over a December rate rise undermined speculative support for the currency.

Dollar loses momentum as softer Fed signals meet growing US political uncertainty

Softer policy signals from the Fed, together with growing political uncertainty, explain the US Dollar's recent loss of momentum, according to analysts at MUFG. In a note, MUFG says: “A damaging defeat for the Republicans could put a dampener on US dollar strength, but we don’t expect it to be a game changer on its own,” adding that it “would limit room for further fiscal stimulus and could increase market attention on the potential for less market-friendly policies beyond the current Presidency.”

Turning to market developments, MUFG attributes some of the Dollar's reduced appeal to the fact that “the Fed’s policy update was less hawkish than expected, and AI-related US equities came under renewed selling pressure,” while also noting that “the 2-year US Treasury yield has fallen by almost 40bps from the high at the end of September,”. A further potential influence on the Dollar and wider rate expectations is the Treasury's forthcoming announcement: MUFG says that “market participants will be watching closely this week’s Quarterly Refunding Announcement from the US Treasury,”.

US midterm elections: key questions answered

Halfway through a president's four-year term, the US holds federal elections known as the midterms. All 435 seats in the House of Representatives and about one-third of Senate seats are contested. In many states, voters also elect governors and other state and local officials.

Tuesday, 3 November 2026 is Election Day, in accordance with federal law specifying the Tuesday after November's first Monday. Many states already have early and postal voting under way.

Control of both chambers of Congress during the final two years of President Donald Trump's term will be decided by the elections. The party holding a majority determines the legislative agenda and selects committee leaders. In the Senate, it also controls the confirmation of judges and senior officials.

Presidential elections take place every four years, with the next scheduled for November 2028, so the president is not on the midterm ballot. The midterms are frequently viewed as a referendum on the incumbent president's party, which has historically tended to lose seats in the House.

A modest, temporary US Dollar response is what most analysts anticipate, rather than a sustained trend. Markets widely regard a divided Congress as the most likely outcome and have partly priced it in, while Treasury yields may respond more visibly to the results. Results that increase expectations for fiscal stimulus generally support both yields and the US Dollar; conversely, legislative deadlock restricting additional spending can weigh on both. Funding disputes or debt-ceiling stand-offs may also briefly support the Dollar through safe-haven demand. Across six to twelve months, however, economic growth and Federal Reserve policy carry more weight than the election result.

Historically, US equities have tended to weaken ahead of midterm elections before strengthening afterwards. Since 1950, the S&P 500 has recorded gains 12 months after every midterm vote, a record of 19 out of 19, averaging about 15%. Analysts attribute this pattern to the reduction in uncertainty after the results become clear. Past performance does not guarantee future returns, and some strategists caution that elevated valuations in 2026 could challenge that run.

With legislative deadlock reducing the likelihood of sweeping tax, spending and regulatory changes, markets have frequently responded favourably to divided government. Historically, when a Republican has held the presidency, the S&P 500 has performed well in the years after midterms that divided control of Congress. Funding deadlines, debt-ceiling disputes and congressional investigations remain risks that can increase short-term volatility.
