The tax benefit of interest deductibility encourages debt financing, but regulatory constraints create dependency between bank leverage and asset risk. Using a large international sample of banks this paper shows that banks located in high-tax countries have higher leverage and lower average asset risk-weights. This trade-off is stronger when regulation is more stringent and for banks with less capital. Non-financial firms' leverage and asset risk are positively related to tax rates, as further evidence of the regulatorily induced adjustment of portfolio risk. A difference-in-difference analysis provides support for a causal interpretation of these results. Overall, higher tax rates are positively correlated with systemic risk, suggesting that the lower asset risk does not offset the risk-inducing effect of tax rates on bank leverage.
