In this paper, we develop a new capital adequacy buffer model (CABM) which is sensitive to dynamic economic circumstances. The model, which measures additional bank capital required to compensate for fluctuating credit risk, is a novel combination of the Merton structural model which measures...

This paper provides evidence for regulatory arbitrage within the class of assetbacked securities (ABS) based on individual asset holding data of German banks. I find that those banks operating with tight regulatory constraints pick the securities with the highest yield and lowest collateral...

We propose an algorithm to model contagion in the interbank market via what we term the credit quality channel. In existing models on contagion via interbank credit, external shocks to banks often spread to other banks only in case of a default. In contrast, shocks are transmitted via asset...

In September 2009, G20 representatives called for introducing a minimum leverage ratio as an instrument of financial regulation. It is supposed to assure a certain degree of core capital for banks, independent of the controversial procedures used to assess risk. This paper discusses the...

Business cycles imply liquidity risks for banks. This paper explores how these risks influence bank lending over the cycle. With forward-looking banks, lending cycles, credit booms and busts, or suppressed and highly fragile bank systems can emerge, depending on the magnitude of liquidity risks....

How does asset encumbrance affect the fragility of intermediaries subject to rollover risk? We offer a model in which a bank issues covered bonds backed by a pool of assets that is bankruptcy remote and replenished following losses. Encumbering assets allows a bank to raise cheap secured debt...

We develop an operational model of information contagion and show how it may be integrated into a mainstream, top-down, stress-testing framework to quantify systemic risk. The key transmission mechanism is a two-way interaction between the beliefs of secondary market investors and the...

We analyze the determinants of real estate and credit bubbles using a unique borrower-lender matched dataset on mortgage loans in Spain. The dataset contain real estate credit and price conditions (loan principal and spread, and the appraisal and market price) at the mortgage level, matched with...

Model-based capital regulation is considered to be one of the key innovations of Basel II. The objective of this innovation was to make capital charges more sensitive to risk. Using data from the German credit register, and employing a difference-indifference identification strategy, we...
