Abstract
Firms may face bottlenecks forcing them to cut activity and adjust prices when monetary tightening financially constrains their business partners. This column focuses on firms producing intermediate goods in the US to show how monetary policy can have ‘ripple effects’ along supply chains through input-output linkages involving financially constrained firms. These transmission channels of monetary policy may be especially relevant in the post-Covid context of higher corporate leverage, significant supply chain disruptions, and inflationary pressures
