摘要

This paper investigates whether financial risk can lower rather than raise business lending rates, using U.S. data from 1998 to 2022, including the zero-lower-bound (ZLB) period. Within a loanable-funds framework, the autoregressive distributed lag (ARDL) estimates of steady-state multipliers, cointegration relationships, and asymmetric adjustments reveal a negative risk-rate relationship: heightened financial risk reduces investment more than saving, lowering equilibrium lending rates even as risk premiums rise. These results align with financial-friction and low-rate theories, including credit-rationing, financial-accelerator, and reversal-rate mechanisms. The findings highlight the limits of monetary easing in low-rate environments and call for macroprudential measures that mitigate investment risk and strengthen credit transmission.
