This tag covers the analysis of business cycle phases: expansion, peak, slowdown, recession and recovery. It helps locate the economy in its temporal dynamic and anticipate coming inflections. Knowing where we stand in the cycle is fundamental to interpreting monetary policy decisions and market moves. Cycles never repeat identically, but their mechanisms remain readable.
Long-term industrial cycles shape the real economy through productive capacity, infrastructure and the deep inertias they generate. Operating across decades, they define potential growth far beyond quarterly fluctuations.
Inventory variations can account for the bulk of quarterly GDP changes while saying little about the underlying trend in final demand. The bullwhip effect propagates these adjustments along the supply chain, amplifying business cycle fluctuations beyond what real demand would justify.
Each business cycle is shaped by a unique institutional, technological and geopolitical context. Monetary regimes, debt structures and value chains alter the mechanisms at work. Historical analogy remains a useful reasoning tool but a flawed predictive grid.
Reading employment resilience as proof that the cycle remains healthy inverts the actual sequence. Hiring and firing costs, skill retention and a cascade of intermediate adjustments — overtime, short-time work, hiring freezes, voluntary departures — mean the labour market is a lagging indicator by construction. Across the last four US recessions, peak job destruction came 6 to 9 months after the official start of the contraction.
Regional cycles do not move in lockstep. Three structural channels — monetary policy, fiscal policy, productive specialization — explain why growth gaps between the US, the euro area, and Asia are widening rather than closing. Why aggregate readings of 'global conditions' increasingly miss what matters.
The output gap between actual and potential GDP structures the cycle's adjustments — but potential itself moves. A closing gap can signal accelerating activity or, just as easily, a downward revision of potential. The distinction matters for monetary and fiscal policy calibration.
