The possibility of an early election for the Japanese prime minister has triggered fiscal panic, causing the dollar to hit an 18-month high against the yen.
2026-01-14 15:33:57
On Wednesday (January 14), the USD/JPY pair fluctuated at high levels during the European session, briefly touching an 18-month high of 159.44 before trading around 159.10. This movement highlights how political dynamics influence currency markets through expectations of fiscal direction rather than immediate policy actions. This relationship is primarily correlated but reinforced by market precedent, reflecting investors' growing sensitivity to domestic political uncertainty in Japan.
Reports suggest that Prime Minister Sanae Takaichi may announce a snap election for the House of Representatives on February 8, reigniting market expectations for potential fiscal expansion, a scenario often accompanied by concerns about increased government spending and larger-scale debt issuance.
The yen faced increased pressure due to weak performance at a five-year Japanese government bond auction. Demand at the auction was described as cautious, with investors seeking higher yields and avoiding aggressive positions. According to Akimoto Morimoto, chief trading desk strategist at Mizuho, the bidding reflected anxieties related to the potential dissolution of the House of Representatives, concerns about fiscal expansion, and increased market volatility.
The lackluster response to the bond issuance indicates that investors are cautious about increased government borrowing, especially given the rising uncertainty surrounding fiscal policy. While weak auction demand does not necessarily lead to currency depreciation, it is typically accompanied by negative sentiment towards government assets, reinforcing downward pressure on the yen through perceived risks.
As the USD/JPY pair approaches the psychologically significant 160 level, market participants are increasingly wary of potential intervention by Japanese authorities. DBS analysts point out that while verbal warnings remain the primary defensive tool, the lack of clear guidance on the timing or scale of intervention continues to fuel speculative pressure against the currency.
This dynamic illustrates how uncertainty itself can amplify currency weakness. Without clear signals from policymakers, traders tend to test perceived tolerance levels, especially when market momentum favors further depreciation.
While the yen weakened, the dollar remained relatively stable, fluctuating near its one-month high of 99.27. US December inflation data showed consumer prices rose 0.3% month-on-month, largely in line with expectations, reinforcing market consensus that the Federal Reserve will keep interest rates unchanged at its next meeting in late January.
Federal funds futures currently imply a 98.3% probability that interest rates will remain unchanged, up from 95.6% the previous day. Support for the Federal Reserve's independence from global central bank governors and Wall Street executives has further stabilized sentiment towards the dollar, despite political rhetoric questioning the institution's autonomy.
Analysts emphasize that as long as inflation remains under control, indirect challenges to the Fed's independence are unlikely to trigger significant market turmoil, reflecting the causal relationship between inflation control and policy credibility.
The weekly chart shows that the USD/JPY pair is significantly above the upward-trending 20-week exponential moving average (EMA) at 154.18, highlighting a strong bullish trend.
The 14-week Relative Strength Index (RSI) is at 70.85 (overbought zone), indicating that momentum has been overextended and upside potential may be limited.
With excessive momentum, further gains may slow, and the market may enter a consolidation phase.
If a pullback occurs, it is expected to find support at the 20-week EMA (154.18). As long as the exchange rate remains above this moving average, the trend bias remains positive.

Conclusion : Overall, the yen's depreciation highlights the foreign exchange market's sensitivity to political and fiscal expectations. While no substantial policy shift has yet occurred, speculation surrounding the election, fiscal expansion, and demand in the bond market has collectively weakened market confidence in the currency. Whether this pressure persists will depend less on short-term headlines and more on how clearly the Japanese authorities communicate their fiscal and monetary policy intentions in the coming weeks.
At 15:26 Beijing time, the US dollar was trading at 159.11/12 against the Japanese yen.
