The financial fragility of Estonian households: Evidence from stress tests on the HFCS microdata

This paper analyses the financial fragility of the Estonian household sector using microdata from the Household Finance and Consumption Survey (HFCS). We use a stress-testing framework where the probability of default is evaluated on the basis of the financial margin (i.e. the ability to service debt from current income) and the availability of financial buffers. The HFCS data from household interviews are complemented with information from administrative registers. This lets us evaluate and compare measures of financial vulnerability that draw on data from different sources. We derive a set of indicators to identify households that are financially distressed and analyse the sensitivity of financial sector loan losses to adverse shocks. The stress-test elasticities are assessed separately for three standardised negative macroeconomic shocks: a rise in interest rates, an increase in the unemployment rate, and a fall in real estate prices. In addition, we evaluate the impact of a simultaneous shock mimicking the dynamics of these three variables during the Great Recession. It is found that: (1) despite there being a lot of households with financial difficulties, the risks for banks from the household sector are limited; (2) financial fragility is strongly negatively related to income; (3) the loan default rate of households is most sensitive to shocks to the unemployment rate and the interest rate, while the loan losses of banks are affected most by real estate price shocks; and (4) compared with the survey data, the information collected from administrative sources points to higher household default rates and larger bank losses.
