Taiwan Overnight Interbank Rate Hits 16½-Year High of 0.825%, Returning to Global Financial Crisis Levels

The overnight interbank lending rate reflects short-term funding supply and demand among financial institutions and is an important gauge of central bank monetary policy and market liquidity. Taiwan's financial markets faced higher funding costs in March 2026 as quarter-end demand peaked, fighting in the Middle East intensified and major central banks shifted toward tighter policy.

Central bank data showed Taiwan's overnight interbank lending rate rose as high as 0.827% in March 2026, its highest level in nearly seven months. The rate has also remained above 0.8% for 22 consecutive months. Financial institutions stepped up funding operations for quarter-end settlements in late March, while the widening conflict increased demand for hedging and financing, further tightening short-term liquidity.

The financial industry’s overnight interbank rate reflects the cost of short-term New Taiwan dollar funding between banks and is an important gauge of market liquidity for Taiwan’s central bank. Cash demand from companies and the public rose in February during the Lunar New Year holiday, increasing pressure on banks’ reserves and funding operations and drawing market attention to the rate increase.

The weighted average overnight interbank rate rose to 0.819% in February and touched 0.825% during the month, its highest level in nearly four months. Markets expect short-term funding to remain tight in March because of quarter-end demand and disruptions from international developments. The central bank is expected to maintain a generally tight policy stance while allowing some flexibility, balancing liquidity with interest-rate stability.
