The Japanese yen strengthened toward 156 per dollar on Friday, reaching its highest level in five weeks before paring its advance. The move came as a global selloff in technology and artificial intelligence stocks increased demand for safe-haven assets.

The equity downturn intensified during the week after Meta Platforms’ plans to increase capital expenditure renewed concerns about how technology companies would finance the expansion of AI infrastructure. Investors’ concerns over potentially higher borrowing requirements contributed to pressure on technology shares and supported demand for defensive currencies.

The yen’s initial advance reflected its appeal during periods of market uncertainty. However, the subsequent pullback showed that the currency’s gains remained sensitive to changing market conditions.

Japanese Inflation Strengthens Bank of Japan Policy Expectations

Japan’s latest inflation figures provided an additional source of support for the yen. Both headline and core consumer inflation increased by 2.1% year-on-year in September, reaching their highest levels in nine months.

The data pointed to continued price pressures as a weaker yen and elevated energy prices increased import costs. With underlying inflation returning above the Bank of Japan’s 2% target, expectations for another interest rate increase this year have strengthened.

The central bank is widely expected to leave interest rates unchanged at its upcoming meeting. Such a decision would not necessarily rule out further tightening, with December emerging as a potential window for another rate increase.

For currency markets, the timing and likelihood of additional monetary tightening remain important considerations. A more restrictive policy outlook could support the yen by narrowing the interest-rate disadvantage against the US dollar, although the currency’s direction will also depend on broader financial conditions.

USD/JPY Remains Sensitive to Market and Policy Signals

The USD/JPY exchange rate rose to 156.8950 on October 23, 2026, gaining 0.08% from the previous session. Despite the yen’s recent monthly appreciation, the currency remains weaker over the longer term, with USD/JPY reflecting a 2.67% increase in the dollar’s value against the yen over the past 12 months.

Historical data cited in the market report places the exchange rate’s record high at 358.44 in January 1971. The latest movement therefore represents a short-term recovery within a longer-term period of yen weakness.

The combination of safe-haven flows and inflation-driven policy expectations has created competing influences on the currency. Market participants will need to assess whether these factors can sustain the yen’s recovery beyond its recent gains.

What Investors Should Watch Next

Attention will center on the Bank of Japan’s upcoming policy decision and any signals regarding a possible December rate increase. Further inflation data will help determine whether price pressures remain sufficiently persistent to justify tighter monetary policy.

Global technology-sector performance and broader risk sentiment will also remain relevant. Continued market volatility could support safe-haven demand, while a stabilization in equities may reduce that support. The yen’s near-term direction will depend on how these market forces interact with expectations for Japan’s interest-rate path.
