October 31: Sri Lanka’s Colombo-based headline inflation increased to 8.3% in October from 8.0% in September, according to the Central Bank of Sri Lanka’s October 30 update. Core inflation also rose, while non-food items accounted for most of the month-on-month increase in the index. The figures describe the Colombo Consumer Price Index, not the separate national price index.
Key highlights
- CCPI headline inflation reached 8.3% year on year.
- Food inflation was 8.8%; non-food inflation was 8.0%.
- Core inflation increased to 5.6% from 5.4%.
- The overall index rose 0.35% from September to October.

What changed in October
The central bank said food inflation edged up from 8.7% to 8.8%, while non-food inflation increased from 7.7% to 8.0%. Non-food items contributed 0.33 percentage point of the monthly index increase, largely through restaurants and hotels; food contributed 0.02 point.
The Department of Census and Statistics’ current CCPI page records an October index level of 209.9 on the 2021=100 base. Its release is dated October 30. The index level and the inflation rate are different measures: one describes the basket relative to its base period, while the other describes the change over a specified interval.
At a glance
| Measure | September 2026 | October 2026 |
|---|---|---|
| Headline CCPI inflation, annual | 8.0% | 8.3% |
| Food inflation, annual | 8.7% | 8.8% |
| Non-food inflation, annual | 7.7% | 8.0% |
| Core inflation, annual | 5.4% | 5.6% |
Annual and monthly inflation answer different questions
The 8.3% figure compares prices with October a year earlier. The 0.35% figure compares the index with September this year. They are not conflicting estimates and should not be added together. A household reading the release needs to know which time comparison a headline is using.
Our calculation: the headline annual rate rose 0.3 percentage point, from 8.0% to 8.3%. Core inflation rose 0.2 point. Non-food’s 0.33-point contribution represents approximately 94% of the reported 0.35-point monthly increase, calculated as 0.33 divided by 0.35. That share is approximate because the published contributions are rounded.
It does not mean that 94% of household spending went to non-food items, or that non-food prices rose by 94%. A contribution measures how a component affects the aggregate change; an expenditure share describes the basket’s composition. Confusing the two would substantially misstate the release.
Why core inflation and coverage matter
Core measures exclude specified volatile components to help assess underlying price pressure. An increase in the core measure alongside headline inflation makes it useful to examine a wider range of categories, rather than looking only at one food item. It does not establish that every item in the core basket became more expensive.
The CCPI is a Colombo-based measure. Readers should avoid presenting it as the National Consumer Price Index or assuming it captures every household’s experience across Sri Lanka. A household buying a different mix of goods and services can face a different change in its own expenditure.
Inflation also describes a rate of change, not a judgment that prices are affordable. Even a future decline in the annual rate would normally mean prices are rising more slowly, unless the rate itself becomes negative. It would not automatically reverse earlier increases in the price level.
What the central bank expects next
The CBSL said its September policy-round projections envisaged high-single-digit headline inflation through the first quarter of 2027, followed by an easing towards the 5% target. It explicitly made that outlook conditional, including on a gradual dissipation of Middle East tensions and their spillovers.
That is a forecast with assumptions, not a guaranteed path. The next tests will be subsequent monthly releases, the balance of food and non-food contributions and whether core pressure moderates. The October inflation statement does not itself announce a new interest-rate decision, and the figures should not be presented as evidence that one has already been taken.
