 We use the introduction of covered bonds in Norway in 2007 together with administrative and supervisory data at the bank- and loan-level to investigate the effect of asset encumbrance on the composition of bank balance sheets and bank risk. We show that covered bonds - despite being collateralized with mortgages - leads to a shift in bank lending from mortgages to corporate loans. The marginal corporate borrower is young and low-rated, suggesting that overall credit risk increases. At the same time, we find that total balance sheet liquidity increases. Overall, the beneficial effects of increased liquidity on bank risk outweighs any negative effects of increased credit risk, ultimately reducing risk premia on total and unsecured funding. The effects are driven by banks with low initial liquidity and high risk-adjusted returns on firm lending.

Collateralized Loan Obligations (CLOs) are non-bank entities securitizing high-yield loans and trading these on secondary markets. They are decisive for the functioning of the leveraged loan market and therefore refinancing opportunities of firms. We assess how CLOs change their trading behavior when public attention to climate change rises. We find that CLOs increase exposure to high emission loans at lower prices. CLOs with experience in trading brown loans and younger CLOs with a stable liability structure drive the effects. We conclude that CLOs take on the role of arbitrageurs when public attention to climate change is pronounced.

This paper demonstrates how spillovers between firms can exacerbate the effect of targeted asset purchase programs on the economy. Targeted asset purchases are an important tool of the European Central Bank to contain a resurgence of the sovereign debt crisis in times of rising interest rates. Firms linked to banks affected by targeted purchases reduce investment and there are negative spillovers on the investments of firms operating within the same agglomeration. The result is important for two reasons: First, it provides evidence on how targeted purchases can slow down economic growth. Second, it shows the importance to consider spillovers when assessing crisis measures by central banks, because spillovers can cover up direct effects.

Do targeted asset purchases alter business dynamics of small and medium sized enterprises (SMEs) and their plants? In July 2022, the European Central Bank (ECB) established the Transmission Protection Instrument (TPI), which allows for targeted asset purchases to prevent a resurgence of the sovereign debt crisis during times of rising interest rates. To investigate unintended consequences of such crisis tools, we assess a similar program, conducted by the ECB between 2010 and 2012. We find that plants linked to banks exposed to the targeted asset purchases are approximately 20% less likely to exit. We observe heterogeneous effects depending on the capitalization of banks and productivity of firms.

We construct a novel dataset to measure banks’ complexity and relate it to banks’ riskiness. The sample covers stock listed Euro area banks from 2007 to 2014. Bank stability is significantly affected by complexity, whereas the direction of the effect differs across complexity measures.
