Lee Hardman from MUFG analyses how Japan’s election risks are affecting the Japanese Yen. USD/JPY has exceeded the 157.00 level due to expectations that the ruling coalition will enhance its majority. This has resulted in increased Yen selling, although a recent JGB auction saw strong demand, indicating potential support for the bond market.
The latest opinion poll from Japan suggests the ruling coalition is on track to solidify its majority in the Lower House. This strengthens market predictions that Prime Minister Takaichi will continue her reflationist policy agenda, prompting further Yen and JGB selling.
Positive News For JGBs
Despite the currency challenges, JGBs have some positive news. The 30-year JGB auction demonstrated stronger demand, which may counteract the pressures on the Yen to some extent.

We are seeing the Japanese Yen weaken, with USD/JPY now trading above the 157.00 level. This is largely driven by political expectations that Prime Minister Takaichi’s ruling coalition is on track to strengthen its majority in the coming election. This outlook reinforces the case for her “reflationist” policies to continue.
Interest Rate Differential
The fundamental picture supports this yen weakness, as the interest rate differential between the Bank of Japan and the US Federal Reserve remains significant. As of today, the BoJ’s policy rate is just 0.1%, while the US Fed Funds Rate stands at 3.5%, making it unattractive to hold yen. Japan’s latest national core CPI for January 2026 came in at 1.9%, still just shy of the central bank’s 2% target, giving them little reason to tighten policy aggressively.
For derivative traders, this political momentum suggests positioning for further yen depreciation in the near term. We are seeing an uptick in demand for USD/JPY call options, particularly those with strike prices targeting the 158.00 and 160.00 levels. This playbook feels very similar to the profitable short-yen strategies we witnessed during 2023 when the rate differential was the dominant theme.
However, we must note some contradictory signals that could introduce volatility. The strong demand seen in the most recent 30-year Japanese Government Bond auction indicates there is still an appetite for Japanese debt. This could provide pockets of support for the yen and suggests the move higher in USD/JPY may not be a simple one-way trade.
