Inflation in the eastern euro area: reasons and risks

10 January 2024

By Matteo Falagiarda

Since 2021 inflation in euro area countries in central and eastern Europe (EACEE) has significantly outpaced that of the euro area as a whole.^[1] The differentials have narrowed in recent months but remain high for core inflation, which excludes energy and food prices (Chart 1). If large cumulated inflation differentials persist in a monetary union like the euro area, they can lead to competitiveness losses. This, in turn, could stoke country-specific macroeconomic vulnerabilities, such as deteriorating current accounts, higher external debt, downward demand pressures and rising unemployment. So understanding the sources of high inflation is important to deal with the associated risks.

Strong impact of global shocks

Part of the reason for the relatively high initial inflation in EACEE countries is their vulnerability to recent adverse global shocks: disruptions in global supply chains, supply-demand imbalances after the COVID-19 pandemic as well as the ramifications of the Russian invasion of Ukraine. These shocks hit all European economies. But their impact was stronger in EACEE countries, in part due to certain structural features of these economies (Chart 2).

First, EACEE countries typically display a higher energy intensity of production than the euro area average, mainly owing to larger energy-intensive sectors (i.e. manufacturing and transport) and fewer energy-efficient appliances and buildings. Second, the share of energy and food in their consumption baskets is higher than the euro area average, which we often see in economies with lower average incomes. Third, most of these economies depended heavily on Russian energy prior to the outbreak of the war, making them more vulnerable to energy supply disruptions. Fourth, these countries are deeply integrated in global value chains (GVC), implying a larger impact of global supply bottlenecks.^[2]

Persistent domestic price pressures

While external shocks were an important driver of initial inflation differentials, domestic factors also play a prominent role (Chart 3). How much pipeline pressures (those emerging at the early stages of the production and distribution chain) ultimately pass through to consumer goods partly depends on how much firms absorb them by reducing profit margins. While euro area firms have recently expanded unit profits, recouping past real profit losses and building buffers amidst high uncertainty, the unit profit increase was larger in the EACEE region. This has an effect on domestic price pressures. The larger increase in unit profits in EACEE countries possibly reflects the stronger pipeline pressures, the more pronounced impact of global supply bottlenecks, or a lower degree of competition among firms, especially in the smaller countries of the region.

Labour market conditions have also remained tight in all EACEE countries, with historically low unemployment rates and persistent labour shortages resulting in robust wage growth in excess of productivity growth. This exerted upward pressure on inflation, albeit with limited risk of a price-wage spiral. Shortages in labour supply are apparent from less favourable developments in the labour force and working age population in these countries compared to the euro area overall. These trends are due to migration outflows of highly skilled young people and a rapid population ageing.

Stronger domestic price pressures in EACEE countries may have also reflected that higher inflation temporarily reduced real interest rates. As the pick-up in inflation started earlier and was stronger than in the rest of the euro area, borrowers in these countries have temporarily experienced a decline in the real value of their outstanding debt. In addition, to the extent that a continuation of relatively high inflation has been expected, ex-ante real financing costs could have been relatively low. Both factors, combined with resilient labour markets, may have contributed to stronger (albeit now moderating) domestic demand and credit dynamics.^[3]

Analysis confirms that the bulk of the initial increase in inflation in EACEE countries reflected global external shocks (Chart 4). The estimates indicate that external shocks played a strong role in boosting inflation above the euro area aggregate. At the same time, the model shows that domestic price pressures have increasingly contributed to the widening of inflation differentials vis-à-vis the euro area. While external sources of inflation eased since the end of 2022, domestic factors are estimated to have continued to exert significant upward pressures on inflation in the most recent period as well.

Conclusions

The recent drop in energy prices and the unwinding of global supply bottlenecks have already begun to narrow headline inflation differentials of EACEE countries vis-à-vis the euro area. However, domestic price pressures, in part resulting from a stronger pass-through of external shocks amidst tight labour markets, are keeping underlying inflation in these countries persistently higher than the euro area average. At the same time, high cumulated inflation increased the relative price level, eroding price competitiveness, as reflected by the strong appreciation of the real effective exchange rates, implying that these countries might be confronted with rising external vulnerabilities and the related consequences.

These developments point to the need for policy action. As the single monetary policy cannot address such country specific developments, national fiscal and structural policies are best suited to mitigating potential risks. The precise policy response will depend on country-specific features. In the near term, a tighter fiscal policy stance could help to dampen inflationary pressures stemming from domestic demand. In addition, structural policies could support the competitiveness of these economies, their potential growth and resilience to future shocks, for example by fostering investment in innovation and human capital as well as strengthening adjustment flexibility.
