USD/JPY Movement Overview
The US dollar slipped against the Japanese yen on Thursday 22 October 2026 as a steep sell-off in artificial intelligence stocks on Wall Street drove investors toward safer assets. The yen surged to 156.80 per dollar, its strongest level since 18 September, as of 04:53 UTC+8 on 23 October 2026.
Key Driver Behind The Move
The decline in US technology stocks was led by jitters over the large amounts of debt companies are issuing to fund AI infrastructure. Meta Platforms, a major AI hyperscaler, indicated a slight rise in its capital spending forecasts and announced a new class of non-voting stock to raise capital for its AI plans.
The dollar, which can be heavily affected by capital spending concerns, was passed over for the traditional safety of the yen. The yen also broke out of its October trading range, forcing short-covering flows.
Market Data And Reaction
US Treasuries rallied as investors sought safety, with the 10-year yield falling nearly 20 bps to around 4.95%, its biggest one-day decline since March 2023. The Nasdaq had its worst day since June. The yen extended gains in Asian trade on Friday, reaching its strongest level in more than a month as the dollar weakened further.
Fears of official intervention by Japanese authorities near the 158 level continue to discourage traders from rebuilding aggressive long-dollar positions.
Broader Market Implications
The dollar’s decline was not uniform. The euro edged lower, with its upside constrained by political and fiscal turmoil in France.
With the US economic calendar light and the Federal Reserve in a blackout period, catalysts for the dollar were limited to oil prices, the bond market and Wall Street. The Fed is widely expected to hold rates steady next week. Deutsche Bank analysts led by Matthew Luzzetti said they expect Chair Kevin Warsh to point to recent inflation data as backing the September view that the Fed will probably need to tighten further over time.
Money markets have fully priced in a Bank of Japan hold, and investors are scrutinising Governor Kazuo Ueda’s updated inflation projections. Swaps markets are increasingly pricing the next BOJ rate increase for early next year.
