Sahm Rule

The Sahm Rule is the unemployment-based recession indicator discussed in EP39 风满楼下集：全球衰退慢慢逼近，严防死守步步为营！漫聊下半年美股、美债、汇率. The host explains it as a rule where a three-month moving average unemployment rate rising materially above its prior twelve-month low has historically signaled that a recession has already started.

Key Claims

• The episode treats the rule as a serious warning, not a precise market-timing signal.
• The speakers note a possible distortion in this cycle: a larger labor supply can raise unemployment without the same meaning as broad demand destruction.
• The rule matters because it can shift how markets interpret Federal Reserve cuts and U.S. Recession Risk.

Connections

• U.S. Recession Risk — macro question the indicator supports.
• Federal Reserve and Monetary Policy Lag — policy timing can look late if the labor-market signal has already triggered.
• Investment Risk Management — indicator use should lead to risk controls rather than all-or-nothing predictions.
