Many of Asia's central banks spent 2025 easing policy. The Reserve Bank of India cut its repo rate by 125 basis points that year, and the Monetary Authority of Singapore loosened its currency settings twice. In 2026 the direction has reversed. Central banks in Indonesia, South Korea, Japan and India have all raised borrowing costs, Singapore has tightened, and the U.S. Federal Reserve has resumed increases.

A common thread is energy. Central bank statements and meeting records from Washington to Jakarta cite conflict in the Middle East and higher oil prices as forces pushing up inflation, while weaker currencies in Korea and Japan have added to imported costs.

Who Moved, and by How Much

Bank Indonesia has moved furthest among the banks reviewed here. It held its BI-Rate at 4.75% from January to April, then raised it a combined 100 basis points in May and June to 5.75%, according to Bisnis Indonesia and Trading Economics. It has held since, but in October it raised its deposit facility rate to 5% and expanded hedging incentives to support the rupiah.

The Bank of Korea raised its base rate to 2.75% on July 16, its first increase since January 2023, and to 3% on Aug. 27, Trading Economics and FocusEconomics reported. In July it cited June inflation of 3.2%, a weaker won, rising home prices and fast household credit growth, according to Trading Economics. It paused on Oct. 22.

The Bank of Japan, which raised its rate to about 0.75% in December 2025, moved to about 1% in June and 1.25% in September, according to MTS Insights' record of decisions. That is its highest level since 1995, The Nation reported.

The Reserve Bank of India raised its repo rate to 5.5% on Oct. 7, its first increase since February 2023, according to HelloBanker and 5paisa. It had cut rates by 125 basis points in 2025, according to brokerage Tradejini.

The Monetary Authority of Singapore, which manages the Singapore dollar rather than an interest rate, increased the slope of its currency band slightly in April and very slightly in July, after easing twice in 2025. It held in October.

The Fed raised its target range to 3.75% to 4% on Sept. 16, its first move up since 2023.

Shared Pressures, Different Responses

The pressures behind these decisions overlap. Fed officials cited Middle East conflict as a driver of higher oil and fuel costs, according to BabyPips' account of the September minutes. Bank Indonesia said the conflict was keeping oil and commodity prices high. The Bank of Japan pointed to crude oil costs, wage pass-through and recent yen weakness as forces lifting its inflation outlook, according to MTS Insights. MAS cited higher energy prices and firmer food costs as sources of imported inflation.

Strong growth has made tightening easier to justify in some places. The Bank of Korea raised its 2026 growth forecast to 3.3% from 2.6% in August on a chip export boom driven by artificial intelligence demand, Trading Economics reported. MAS said Singapore's economy grew 5.4% from a year earlier in the third quarter, led by technology-related sectors.

Yet the tools have diverged. Bank Indonesia has leaned on its deposit rate, currency intervention and hedging discounts rather than further increases, and it is cutting bank reserve requirements to free up lending. The Bank of Korea is pausing to judge the effects of two increases. The RBI projects inflation of 5.2% for the fiscal year, and Governor Sanjay Malhotra said a cut is off the table in the near term, according to 5paisa.

China Stands Apart

The People's Bank of China is the clear outlier. Its one-year and five-year loan prime rates have stayed at record lows of 3% and 3.5% for 17 straight months, according to Trading Economics. Third-quarter growth of 4.5% beat expectations, reducing the urgency for more support, and the yuan has been strengthening, Trading Economics reported.

The tightening has not been limited to Asia and the U.S. Trading Economics data list quarter-point increases for the euro area and Australia, both recorded in September.

For investors, the next tests come quickly. The Fed decides on Oct. 28 and the Bank of Japan on Oct. 30. Bank Indonesia's next decision is scheduled for Nov. 18, according to Trading Economics, and the Bank of Korea's for Nov. 26, according to SBS, with the RBI following on Dec. 2-4. Several of those meetings will show whether this year's increases were a short burst against an energy shock or the start of a longer tightening cycle.
