Updated text on core inflation at 15:20 in response to the publication of CNB data on its development.
The CSO confirmed that annual consumer price inflation stabilised at 2.7% in March after slowing slightly in February from 2.8% in January. This reflects a more moderate 0.1% month-on-month growth after stronger New Year increases of 1.3% in January and 0.2% in February.
On a seasonally adjusted basis, this looks like a month-on-month rate of consumer inflation growth of around 0.16%, close to the CNB's inflation target for the second month in a row. I estimate that the main drivers of March's monthly consumer inflation growth were food prices, imputed rent and food services, which have also been among the top five drivers over the past three months. This in turn was corrected by fuel and energy prices.
The CBN posted year-on-year core inflation growth at an unchanged 2.5% in March, a whisker off my initial estimate of 2.46%. However, this rounding suggests month-on-month core inflation growth of around 0.25-0.3% on a seasonally adjusted basis. This remains driven by imputed rents , but also by core services (both around 0.4% m/m) vs. tradable core still around zero. Thus, I see higher core services price momentuminFebruary and March than in the second half of last year. That's probably not entirely surprising when you look at the approximately 8% annualized revenue growth.
Although both headline (2.7% y/y) and core consumer inflation were only 0.1% points ahead of the CBN's forecast, the still strong growth in core services prices is likely to be one of the key factors for the Board's May decision. Especially if the data charge in early May does not turn more dovish.
