Tail-Risk Hedging
Systematic positioning for low-probability, high-impact scenarios — typically via deep-OTM options, gold, USD, and Treasuries.
Definition
Tail-risk hedging accepts a small consistent cost (premium decay) in exchange for large convex payoffs in crisis scenarios. The classic 'crisis offset' portfolio includes deep-OTM SPX puts, USD upside calls, long gold, and long-duration Treasuries — though the last has worked less reliably since 2022.
Tail hedging is hardest to size: too little provides no real protection; too much bleeds returns.
