The credit cycle is the rhythmic pattern of credit availability and credit quality that characterizes all lending markets over time. Like the business cycle, the credit cycle moves through phases — expansion, peak, contraction, and recovery — with each phase characterized by distinctive conditions in credit availability, pricing, documentation, default rates, and recovery values. Understanding where we are in the cycle is one of the most practically important skills for any credit market participant.
During credit expansion, economic growth is strong, corporate earnings are rising, and confidence is high. Lenders compete aggressively for business: leverage multiples rise, spreads compress, documentation standards loosen (cov-lite becomes more prevalent), and underwriting assumptions become increasingly optimistic. Capital flows freely to borrowers who might have struggled to access credit earlier in the cycle. The expansion phase is where most credit losses are underwritten, even though they are not yet visible.
At the cycle peak — often not recognizable in real time — leverage is at maximum, loan structures at their most borrower-friendly, and underwriting assumptions at their most optimistic. Delinquencies and defaults remain low, creating a false sense of security. Rating agencies, investors, and lenders may all be operating with assumptions calibrated to the peak rather than the cycle average. The seeds of future losses have been sown but haven't yet germinated.
Contraction begins when the economic environment shifts: growth slows or reverses, earnings disappoint, credit markets tighten, and lenders begin to pull back. Spreads widen, leverage multiples fall, documentation tightens, and weaker borrowers find credit access constrained or priced out. Default rates begin rising as over-leveraged borrowers from the expansion phase struggle to service debt. Recoveries on defaulted loans fall as distressed assets flood the market simultaneously.
Recovery follows as the economy stabilizes, distressed assets are resolved, weak borrowers are restructured or liquidated, and credit markets re-open to well-credentialed borrowers. Spreads are wide, creating value for investors with capital to deploy. Standards remain tight initially but gradually loosen as competition for new business returns — setting the stage for the next expansion.
The credit cycle's duration varies significantly — expansions can last a decade or more (as in 2010–2020), while contractions can be sharp and short (2020) or extended (2008–2010). Credit investors must calibrate their approach to the cycle phase: building in stress buffers during expansions, deploying capital opportunistically during contractions, and avoiding chasing tightening spreads without considering late-cycle risks.
