A surprise recession could strike after an unexpected jump in the unemployment rate, economist says

• An unexpected rise in the unemployment rate suggests a surprise recession could hit the US economy, according to David Rosenberg.
• The unemployment rate is now 0.5 percentage points above its cycle low to 3.9%, which Rosenberg says is a worrying sign.
• "It messes up the soft landing narrative because once it rises this much from the lows, the recession nobody ever sees coming arrives," he said.

Economist David Rosenberg is growing increasingly concerned that a surprise recession could hit the US economy.
