Macroprudential policy in Europe aligns with the objective of limiting systemic risk, namely the risk of widespread disruption to the provision of financial services that is caused by an impairment of all or parts of the financial system and that can cause serious negative consequences for the real economy.

We provide empirical evidence to support the calibration of a limit on household indebtedness levels, in the form of a cap on the debt-service-to-income (DSTI) ratio, in order to reduce the probability of borrower defaults in Romania. The analysis establishes two findings that are new to the literature. First, we show that the relationship between DSTI and probability of default is non-linear, with probability of default responding to increases in DSTI only after a certain threshold. Second, we establish that consumer loan defaults occur at lower levels of DSTI compared to mortgages. Our results support the recent regulation adopted by the National Bank of Romania, limiting the household DSTI at origination to 40 percent for new mortgages and consumer loans. Our counterfactual analysis indicates that had the limit been in place for all the loans in our sample, the probability of default (PD) would have been lower by 23 percent.
This paper assesses the effectiveness of lending restriction measures, such as loan-to-value and debt-service-to-income ratios, in affecting developments in house prices and credit. We use data on 99 lending standard restrictions implemented in 28 EU countries over 1990–2018. The results suggest that lending restriction measures are generally effective in curbing house prices and credit. However, the impact is delayed and reaches its peak only after three years. In addition, the impact is asymmetric, with tightening measures having weaker association with target variables compared to loosening measures. The association is stronger in countries outside of euro area and for legally-binding measures and measures involving sanctions. The results have practical implications for macroprudential authorities.

This paper discusses findings of the Detailed Assessment of Observance of the Basel Core Principles (BCP) for Effective Banking Supervision in Romania. The supervisory approach of the National Bank of Romania (NBR) has been changing toward a more risk based approach since the previous BCP assessment, but more needs to be done. Further development of the NBR’s supervisory approach will make supervision more effective and in line with the requirements of the 2012 BCP. The NBR may need to devote more supervisory attention to banks’ risk models and building up further expertise in specialized areas such as information technology and market risk. In the area of corrective actions and sanctions, the NBR should review its framework to ensure it is protected from undue legal challenges.
