Sri Lanka has the most expensive cigarettes in the world when measured against purchasing power parity, according to World Health Organisation data cited in a new Oxford Economics assessment.

The finding appears in a report that the Daily Mirror described on Monday, and it arrives attached to an argument: the assessment uses Sri Lanka’s position to question whether the WHO’s global tobacco tax benchmark is a sound measure of policy success.

The argument against the benchmark

The WHO sets a 75% tobacco tax incidence target — that is, taxes should make up at least three-quarters of a cigarette’s retail price. The Oxford Economics assessment argues that hitting a specific tax incidence rate does not necessarily translate into lower smoking prevalence, and that national economic realities rather than a uniform global target should guide tobacco taxation policy.

The report states there is little meaningful relationship between the proportion of taxes in cigarette retail prices and overall smoking rates, and that countries with higher tax incidence rates do not necessarily record lower levels of smoking.

It draws support from the WHO’s own material. The assessment cites a WHO document concluding that the share of taxes in the retail price of cigarettes is not, in itself, an important indicator of tobacco control success, and which emphasises that the retail price — rather than the proportion of it attributable to tax — plays the larger role in influencing smokers’ consumption decisions. The WHO’s Technical Manual on tobacco taxation likewise acknowledges that tax share alone is insufficient to guarantee the success of demand-reduction policies.

On that reading, the assessment argues, a country’s progress should be judged by the relationship between taxation, retail prices and smoking behaviour, rather than by whether it has reached a predetermined tax share.

What the filing does not establish

Readers should treat the headline claim carefully, because the report as described supplies none of the figures that would let anyone check it.

Context

Tobacco pricing in Sri Lanka has been shaped by successive tax increases, and cigarettes remain among the more heavily taxed consumer goods. This desk has reported repeatedly on the enforcement consequences, including Customs destroying smuggled cigarettes worth Rs 677 million last week — a trade whose economics follow directly from a high domestic retail price.

That connection is the one point on which the assessment’s framing and Sri Lanka’s recent record clearly agree: a high retail price changes behaviour, including the behaviour of smugglers.
