Did Quantitative Easing Reduce the Borrowing Costs of Firms? The Risk-Taking Channel

This paper examines the effect of the Federal Reserve’s quantitative easing (QE) on the cost of bank loans and documents large heterogeneous effects across different firms. In QE1, the average loan spread is 22.7% lower compared to the non-QE period. This effect falls in QE2 and OT and then rises in QE3 and the tapering period. The rates of riskier loans are restrained more than less risky loans during QEs as banks take more risks by offering lower rates to attract risky borrowers. The Fed MBS purchases have a larger impact in narrowing the borrowing cost difference between riskier and safer loans than the Fed Treasury purchases. Our results are robust to borrower, year-quarter, and bank fixed effects. Overall, our findings support that the risk-taking channel of QE plays a significant role in the corporate bank loan market
