The IV Ramp Into a Catalyst: How Expected Move Widens Before FOMC
In the days before a big scheduled event, options quietly get more expensive, not because the market is moving, but because it might. The IV ramp is the market pricing uncertainty before it resolves.
Implied volatility reflects the market's expectation of future movement. A known catalyst carries real potential for a large move, so demand for options (to hedge or speculate on the event) rises, bidding up their prices, which is a rise in implied volatility. The closer the event and the bigger its potential impact, the more IV ramps. This isn't the market predicting direction; it's pricing the magnitude of uncertainty the event represents.
What the ramp tells you
The widened expected move quantifies how big a reaction the market is braced for — a useful read on event risk. It also means options are expensive going into the catalyst: you're paying up for that priced-in uncertainty, so a long option needs a move bigger than the expected move just to overcome the inflated premium and the crush that follows. The straddle price is a direct read of the expected move the ramp has built in.
IV doesn't ramp because the market knows what's coming — it ramps because it doesn't. You're buying priced-in uncertainty, and you pay full retail for it right before the event.
Trading around it
The key implication: buying options right before an event means buying expensive, IV-inflated premium that will crush after the catalyst — a poor trade unless the move is large enough to overcome both. For a 0DTE scalper, respect that pre-event premium is rich and the post-event crush is real. NoVo accounts for the volatility environment in its read; understanding the IV ramp tells you why options are pricey into a catalyst and why the timing of an options trade around events matters so much.
