USD/JPY increased to around 157.45 during the early Asian session on Monday, as the ruling Liberal Democratic Party (LDP) in Japan secured a majority in the snap election. This victory allows Prime Minister Sanae Takaichi to push for more fiscal stimulus, influencing the yen’s value against the US dollar.
The LDP coalition captured 352 out of 465 seats in the House of Representatives, with the LDP holding 316 seats. Takaichi plans to accelerate discussions on reducing the sales tax on food, sparking concerns about funding for her increased spending agenda, adding pressure on the yen.
Intervention Strategies
To counterbalance potential yen losses, Japanese authorities may intervene. Finance Minister Satsuki Katayama is poised to engage with markets if deemed necessary, maintaining communication with US Treasury Secretary Scott Bessent to stabilize the currency pair.
Attention shifts to the delayed US employment report for January, scheduled for release on Wednesday. Economists expect an addition of 70,000 jobs with the unemployment rate remaining at 4.4%.
Factors such as the Bank of Japan’s policy, the differential between Japanese and US bond yields, and risk sentiment impact the yen’s value. The yen is often viewed as a safe-haven currency during market instability.
The election victory for Prime Minister Takaichi’s party has weakened the yen, pushing USD/JPY toward 157.50. Her promises of more fiscal spending, potentially funded by debt, are creating a clear upward path for the currency pair. Traders should see this as the dominant trend for now.
Balancing Risks and Opportunities
However, we must be cautious about getting too bullish on USD/JPY at these levels. The Ministry of Finance has explicitly warned about intervening, and their communication with the US Treasury suggests a coordinated view on stability. Fighting an intervention is a risky strategy, as we saw with the sharp pullbacks in late 2024 when the pair crossed the 155 level.
Looking back, this fiscal push complicates the Bank of Japan’s position after it spent 2025 slowly moving away from its ultra-loose policies. National core inflation averaged 2.6% in Japan last year, which normally argues for a stronger currency. This conflict between government spending and central bank policy will likely lead to significant price swings.
The key catalyst this week is the US employment report, which is due on Wednesday. The market is expecting a very low 70,000 jobs added, a sharp drop from the average monthly gains of over 180,000 we saw in the second half of 2025. A weak report could strengthen the case for US interest rate cuts later this year, putting pressure back on the dollar.
Given the high risk of both a continued rally and a sharp reversal from intervention, derivative traders should consider buying call options on USD/JPY. This strategy allows for participation in any further upside driven by stimulus news. It also strictly defines the maximum loss to the premium paid, which is crucial if the government suddenly steps in to strengthen the yen.
The immediate focus should therefore be on managing risk around Wednesday’s US data release. A number well below the already low 70,000 expectation could trigger a rapid sell-off in the pair. This makes holding unhedged long positions into the announcement a considerable gamble.
