Bank of Japan Raises Interest Rate to 31-Year High of 1.25%: What It Means for Global Markets and Indian Stocks

The Bank of Japan (BOJ) raised its policy interest rate by 25 basis points from 1 per cent to 1.25 per cent on Friday, September 18, taking borrowing costs to their highest level in 31 years. The decision was widely expected as the central bank seeks to prevent inflation from moving above its 2 per cent target.

The decision was approved by a 7-2 vote at the BOJ’s two-day policy meeting. Board members Toichiro Asada and Ayano Sato dissented. The BOJ reiterated that it would continue raising rates if its economic and price outlook develops as expected. At 1.25 per cent, the policy rate has moved into the lower end of the BOJ’s estimated neutral-rate range.

BOJ Governor Kazuo Ueda is scheduled to address the media at 3:30 p.m. on Friday. Investors will closely monitor his comments for clues about the timing and pace of further interest rate increases.

The rate hike comes as Japan continues to face inflationary pressure, with rising energy costs and a weaker yen adding to the cost burden. The move also marks another step away from the BOJ’s long-standing ultra-loose monetary policy.

The latest increase is significant for global markets because the BOJ, U.S. Federal Reserve and European Central Bank have all raised borrowing costs in the same month. This marks a notable shift in global monetary policy after years during which Japan remained an outlier with exceptionally low interest rates.

Despite the rate increase, the Japanese yen initially weakened against the U.S. dollar. The yen fell 0.5 per cent to 156.75 per U.S. dollar immediately after the announcement, although it remained stronger than its July levels following coordinated currency intervention by Japan and the U.S. The yen had previously touched a roughly 40-year low of 163.99 on July 23.

The muted yen reaction reflected the fact that the rate hike had already been largely priced into financial markets. The two dissenting votes also reduced expectations of aggressive monetary tightening, according to Market commentary.

Higher Japanese interest rates can affect global capital flows as Japanese investors and institutions may reassess their investments in overseas assets as domestic returns improve. Higher rates could also reduce the attractiveness of yen-funded carry trades, potentially affecting liquidity across global financial markets.

For Indian equities, the immediate market reaction remained limited. At around 9:25 a.m. on Friday, the Sensex was up 177.61 points, or 0.24 per cent, at 74,501.32, while the Nifty 50 gained 46.40 points, or 0.19 per cent, to 23,315.20. Asian markets were also largely positive.

The Indian rupee was also expected to receive some support from easing crude oil prices and potential foreign portfolio inflows linked to the NSE IPO, which may partly offset concerns over tighter global monetary conditions.

There was no broad, direct surge or fall in Indian stocks attributable solely to the BOJ rate hike in early trade. The Nifty 50 and Sensex remained positive, while sectoral movements were influenced by multiple factors, including crude oil prices, global equity trends and domestic flows.

In Japan, the Nikkei 225 rose after the decision despite the rate hike, with the move largely anticipated by investors. The yen’s weakness and the absence of a significantly more aggressive tightening signal helped limit the immediate negative reaction in Japanese equities.

The key market focus now shifts to Governor Ueda’s comments and whether the BOJ signals another rate increase. Investors will particularly watch for indications of further monetary tightening later in 2026, which could influence the yen, global capital flows, carry trades and emerging-market equities, including Indian stocks.
