Seven mistakes in analyzing data from Russia — and how to avoid them

In analyzing data from Russia, researchers must be aware of seven common mistakes. First, treating official figures as market prices is problematic when the state can set these prices. Textbooks often rely on headline figures like inflation and GDP, making them prime targets for manipulation. For example, in 2026, Rosstat's revision of the inflation basket omitted certain clothing fabrics and tracked medicines by generic names, allowing cheaper alternatives to be recorded without quality adjustment.

This distortion affects GDP calculations, as private consumption accounts for a significant portion of GDP. Oil output figures have also been hidden from public release, but prices and grades still appear weekly through closed CDU TEK bulletins or through inferred volumes based on tax rates and coefficients set by the state. It is crucial to identify which parts of the figure are set by the state and how they impact the number.

Secondly, analysts should not repeat another organization's numbers without understanding their warnings or mistakes. The IMF takes a Rosstat figure, makes minor adjustments, and publishes a derived indicator. Researchers then use the IMF's number as raw material, apply standard methods, and produce a "neutral" estimate that is widely cited.

This can be problematic because the data has been shaped for the Kremlin. Real GDP, for instance, is calculated by deflating individual components using specific price indices, which come from Rosstat itself. This creates a circular argument where the inflation figure and the nominal total are both disputed. Therefore, it is essential to trace every number back to its original source and include the source's limitations alongside the figure, rather than in a footnote.

Thirdly, analysts must not ignore decrees that alter the meaning of official indicators. The central bank's key rate is no longer solely used for pricing credit or controlling inflation. In July 2026, the Bank of Russia cut the rate to 14.00 percent, the fifth cut of the year, while simultaneously raising its inflation forecast from 4.5-5.5 percent to 6-7 percent.

These changes render the rate's purpose less about pricing credit and more about inflation control. Another example is the mandated share of gasoline sold on the exchange, which was once 10 percent but has been raised to 15 percent in 2023 and then reduced to 10 percent again in July 2026. This seemingly modest reduction is a result of Resolution No. 1003 of 10 August 2026, which allows up to 8 percent to be counted through confirmed off-exchange deliveries to farms, Russian Railways, builders, or anyone collecting the fuel themselves.

Leaving the headline number unchanged while altering the small print can mislead readers. It is vital to know which official decisions have changed the indicator being used.
