The European Central Bank published an article summarizing research that links asymmetric monetary transmission to firms facing multiple financing constraints. The authors argue that when several borrowing limits bind at the same time, policy tightening has a stronger effect on firm borrowing and capital expenditure than an equally sized easing, because borrowing must adjust to the most rate-sensitive binding constraint when rates rise, but is capped by the least responsive binding constraint when rates fall. The article notes that these are the authors’ views and draws on a recent ECB Working Paper. Using merged Compustat and Refinitiv DealScan data, the research finds that about 65% of United States non-financial corporates face two or more tight financing constraints, suggesting this channel is widespread. Firms with multiple tight constraints were found to reduce external financing more sharply after monetary tightening than they increase it after comparable easing, while firms with one or no tight constraints responded more symmetrically. In the calibrated New Keynesian model, aggregate investment falls by twice as much after a contractionary monetary shock as it rises after an equally sized expansionary shock, and a 0.5-point increase in the interest-rate elasticity of the most sensitive constraint increases the asymmetry in aggregate investment responses by about 20%.

European Central Bank article finds multiple financing constraints amplify monetary tightening effects on investment
An ECB-published research article argues that multiple binding financing constraints make monetary tightening hit firm borrowing and investment more strongly than comparable easing supports them. The underlying data suggest about 65% of US non-financial corporates face at least two tight constraints. In the model, aggregate investment declines by twice as much after tightening as it rises after an equally sized easing shock.
