People love to snark on Chinese economic data as being hopelessly manipulated and unreliable, though for the most part those concerns are overblown. Chinese numbers tend to be directionally correct, even if they may be imprecise.
However, if you’re looking for suspect data, check out the situation in Russia.
Now Russia is going through the same economic turmoil as its fellow BRICs (and more broadly, all emerging markets). Russia’s massive growth before and right after the global economic crisis allowed the country to ignore structural issues that are now proving to be problematic.
But economists are alarmed at the unreliability of the data.
On Aug. 22, Nomura strategists Olgay Buyukkayali and Dmitri Petrov kicked off a multi-volume report on Russia’s weakening economy by noting how poor the official data quality is.
The errors puzzle in the breakdown
Russian growth contains some puzzles. The first is in the expenditures contribution. Q1 growth was 1.6% y-o-y, and statistical discrepancy contributed up to 1.8% on the upside. At this stage the official breakdown of Q2 GDP contributions is not yet available. However, this is not an issue as last quarter’s Rosstat GDP data asked more questions than it answered. If one adds up the contributions of the expenditure components to Q1 GDP, the resulting figure of 0.6% is noticeably lower than 1.6% headline growth. For statistical reasons, the discrepancy is not unusual, but in this particular case it seems that Rosstat cannot figure out where the growth is coming from.
First, the statistical discrepancy is at its historically highest level. Second, despite overall stagnation, household consumption accelerated from 5.8% in Q4 to 6.1% in Q1, although this time with weaker retail sales growth, which intuitively as well as statistically is quite unusual. This creates uncertainty around the official composition of Q1 growth which will hopefully be revised when the Q2 breakdown is released. This could lead to the Q1 and Q2 consumption picture being reassessed (in our view, lower).
Here’s the chart showing a massive statistical discrepancy in Q1.
