Headline inflation in Sri Lanka has surged to levels above the central bank's 5 percent target, driven primarily by rising global energy prices and supply-side shocks, with the monetary authority warning that elevated inflation is likely to persist through the near term.

Sri Lanka's inflation has accelerated markedly in recent months, reaching levels above the Central Bank's target of 5 percent, according to the institution's August 2026 Monetary Policy Report. The headline inflation, which averaged around 2 percent in the first quarter of 2026, has climbed substantially since then. The second quarter saw the Colombo Consumer Price Index reach an average of 5.9 percent, marking an end to an eight-quarter period where inflation had remained below target.

The acceleration is largely attributed to supply-side pressures rather than demand-driven factors. The central bank identified geopolitical tensions in West Asia since late February as a primary cause, pointing to immediate pass-through effects from higher global energy prices into domestic fuel and electricity costs, with spillover impacts across other sectors. Energy and transport inflation rose sharply in the second quarter following upward adjustments to fuel, electricity, and liquefied petroleum gas prices. Food inflation has also been pressured upward by volatile commodity prices and increased transportation costs.

Looking ahead, the central bank projects that headline inflation will remain elevated and above the 5 percent target in the near term before moderating toward the target as supply-side shocks ease and monetary policy tightening takes effect. However, this forecast assumes that West Asian tensions will ease and their economic impact will diminish. The bank acknowledged that risks to the inflation outlook remain tilted toward the upside, citing uncertainty in global commodity markets and potential adverse weather conditions associated with El Niño. The central bank responded to elevated inflation by tightening monetary policy in May 2026, ending an accommodative stance that had been in place since mid-2023.
