Zusammenfassung: 
We address the problem of regulating the size of banks' macroprudential capital buffers by using market-based estimates of systemic risk and by developing a modeling mechanism through which capital buffers can be allocated efficiently across systemic banks. First, a Distance-to-Default type measure relates a bank's default risk to its capital requirements. Second, a correlation structure in the default dependencies between banks is estimated from co-movements in the single-name CDS spreads of the underlying banks. Third, risk minimization and equalization approaches are adopted to allocate the capital requirements in line with a policy balancing the social costs and benefits of higher capital requirements. The model is applied to the European banking sector.
