The Japanese yen slipped as traders positioned for Sunday’s snap election, with markets expecting Prime Minister Sanae Takaichi to extend her hold on power and keep a reflationary policy mix in place.
According to MUFG Bank analysts, Japan’s political backdrop is adding “downward pressure on the yen,” while Polymarket pricing cited by Benzinga shows near-certainty that Takaichi remains prime minister.
Election expectations and market odds
Benzinga reports that Polymarket traders assign a 99% probability that Takaichi is prime minister after the vote.
In the governing parties market, the Liberal Democratic Party stands at 99%, while the Japan Innovation Party is at 22%.
Those probabilities imply what Benzinga calls a “Supermajority” scenario, suggesting the LDP may not need a coalition partner.
That would give Takaichi a “clear runway” to pursue her agenda without extensive legislative negotiations.
Currency and bond market signals
MUFG Bank’s Lin Li, Michael Wan, and Lloyd Chan said USD/JPY is “drifting back toward 160 after its brief correction to 152.”
They warned that local reports of Takaichi’s coalition securing a lower-house majority could raise expectations for government spending.
MUFG cautioned that such expectations “may fuel upward pressure on USD/JPY and long-end JGB yields,” citing concerns over fiscal discipline if markets anticipate larger stimulus.
Policy continuity, defense build-up
Benzinga says traders expect continuity in an aggressive policy stance, including massive fiscal stimulus, a slower path to Bank of Japan rate hikes, and a tougher security posture.
The yen has been “trading heavy,” with USD/JPY near the 157 level heading into the vote.
On the security front, Benzinga notes the Cabinet has already signed off on a record ¥9.04 trillion ($58 billion) defense budget for FY2026, putting procurement plans in focus.
US names tied to defense include Lockheed Martin, RTX, and Northrop Grumman, while Japanese groups include Mitsubishi Heavy Industries, Kawasaki Heavy Industries, and Mitsubishi Electric.
Political backdrop and international ties
Benzinga also reports that US President Donald Trump endorsed Takaichi on Truth Social and plans to host her at the White House on March 19.
The endorsement is a rare intervention by a US leader in a G7 ally’s election.
Some analysts cited by Benzinga warn of a potential “triple dip” if markets decide the government’s “Sanaenomics” stimulus threatens fiscal sustainability.
In that scenario, stocks and bonds could fall together while the yen breaks past 160 against the dollar.
Sunday’s result will shape expectations for fiscal policy, the path of Bank of Japan tightening, and defense outlays.
For now, MUFG’s view of a softer yen and the risk of higher long-end JGB yields underscores how political outcomes are feeding directly into currency and rates pricing.
