Sri Lanka's central bank caught markets off-guard by raising its benchmark policy rate by an outsized 100 basis points on Tuesday (May 26, 2026), as policymakers looked to stem inflation and sharp pressure on the currency from soaring energy prices. According to reports from The Hindu, the Central Bank of Sri Lanka (CBSL) raised the overnight policy rate to 8.75% from 7.75%, blaming higher inflation and a depreciating rupee due to the U.S.-Israeli war with Iran. The rate hike significantly exceeded market expectations, with seven out of a dozen economists and analysts polled by The Hindu forecasting only a 25-basis-point or slightly greater change to the rate, citing the deepening impact on foreign reserves from the conflict. As reported by NDTV Profit, Governor P Nandalal Weerasinghe said the aggressive tightening was aimed at stabilising inflation and supporting the currency, while also warning that additional measures could follow if economic risks intensify.

As reported by The Hindu, Sri Lanka, fully reliant on imported fuel, has been battered by the Iran war-driven energy shock that has forced a 40% fuel price hike, rationing, and even public holidays on Wednesdays. According to investingLive Asia-Pacific FX news wrap, the rate hike represents the starkest illustration yet of how the Hormuz closure is being transmitted into emerging market policy rates far from the strait itself. The decision comes as the island nation faces mounting pressure from soaring fuel import costs triggered by the Middle East crisis, which has pushed the Sri Lankan rupee down nearly 9% since March and accelerated inflation.
Inflation has jumped dramatically from 2.2% in March to 5.4% last month, with headline inflation likely to remain above the target of 5% in the period ahead before easing and stabilising around it, according to the CBSL statement reported by The Hindu. The central bank noted that similar to several regional peer currencies, Sri Lanka rupee experienced notable depreciation pressures in recent weeks, with the currency depreciating 8.7% since early March, although conditions have since eased to some extent. According to NDTV Profit, the combination of rising fuel costs linked to the Iran conflict has weakened Sri Lanka's currency, accelerated inflation and forced the central bank into aggressive monetary tightening. The move marks a major shift in policy after last year's rate cuts intended to support growth, with analysts now expecting economic expansion to slow as borrowing costs rise and consumer demand weakens.
The CBSL last changed rates in May 2025 when it reduced them by 25 basis points to boost growth. According to The Hindu, backed by a $2.9 billion programme from the International Monetary Fund, the island is clawing its way out of a deep financial crisis in 2022 caused by a severe shortfall of dollars. The country, still recovering from its 2022 financial crisis, is also awaiting the release of a $700 million IMF tranche expected to support its reserves and broader recovery efforts. The IMF Executive Board will meet on Wednesday (May 27, 2026) to decide whether Sri Lanka will receive this tranche, which would help to top up its reserves, which have now decreased by 3.8% to $6.7 billion as fuel import expenses surged.
