Overview
Risk-on sentiment (rising stocks) often favors higher-yield currencies and commodity currencies. Risk-off (falling stocks) favors safe haven currencies like JPY and CHF. Watch indices like S&P 500 and Nikkei for clues.
Key Indices
S&P 500 reflects US risk sentiment—up often means risk-on, favoring AUD, CAD. Nikkei ties to USD/JPY; Japanese investors repatriate when Nikkei falls. DAX and FTSE matter for EUR and GBP.
Risk On Risk Off
When S&P 500 rises, commodity currencies and higher-yield FX tend to strengthen. When S&P 500 falls, JPY and CHF strengthen as carry trades unwind. VIX above 20 often signals risk-off.
Sector Clues
Sector rotation can hint at flows. Financials up may support USD (rate expectations). Commodity sectors up support AUD, CAD. Defensives up can signal risk-off.
Limitations
Equities and forex can diverge. USD can rise during risk-off (flight to dollar) or risk-on (strong economy). Use equities as context, not a sole signal.
