Bank liquidity shortages during the global financial crisis of 2007–2009 led to the introduction of liquidity regulations, the impact of which has attracted the attention of academics and policymakers. In this paper, we investigate the impact of liquidity regulation on bank lending. As a setting, we use the Netherlands, where a Liquidity Balance Rule (LBR) was introduced in 2003. The LBR was imposed on Dutch banks only and did not apply to other banks operating elsewhere within the Eurozone. Using this differential regulatory treatment to overcome identification concerns and a difference-in-differences approach, we find that the LBR increased the volume of lending by Dutch banks relative to other banks located in the Eurozone. Increased equity, an inflow of retail deposits and subsequent increase in balance sheet size allowed Dutch banks to increase lending despite having to meet the LBR requirements. The LBR also affected the loan composition of Dutch banks (with corporate and retail lending increasing more than mortgage lending) and the maturity profile of loan portfolios. Our results have relevance for policymakers tasked with monitoring the impact of liquidity regulations on banks and the real economy.

Banks play a central role in the financial system and benefit the real economy by managing risk, and providing finance to households, small and medium-sized enterprises, large corporates and governments. However, their complexity, opacity and interconnectedness can elevate bank-level and systemic risks, posing dangers to the financial system and real economy. This was evident during the global financial crisis where taxpayer funded bailouts were used to rescue ailing banks, which in turn led to an overhaul of regulation and supervision. Consequently, safeguarding bank stability and addressing systemic risks via well designed regulations is essential for ensuring economic resilience and societal well-being. This study uses a quasi-natural experimental research design in the form of the Dutch Liquidity Balance Rule (LBR) to evaluate the impacts of liquidity regulation on bank-level stability and systemic risk. Our findings show that following the introduction of liquidity regulation, the stability of Dutch banks increases significantly relative to counterparts in neighbouring countries unaffected by the regulation. The observed reduction in risk stems from improved capitalization and reduced leverage, which contribute to greater financial stability. Systemic risk also decreases. Our findings have relevance beyond our research setting for policymakers tasked with implementing and monitoring the impacts of similar forms of liquidity regulation (such as bank liquidity coverage ratios) post global financial crisis.
