How FOMC week affects options expiration and premiums
· 6 min read
FOMC week options are priced around a known event, so the contracts that expire soon after the announcement usually carry extra implied volatility that can fall once the statement is out. The closer your expiration is to the announcement, the more of the contract’s price depends on that single moment. Contracts that expire the same day are the most exposed, and contracts that expire weeks later are affected much less. Check the Fed calendar for the meeting dates and plan the week around them before you pick an expiration.
FOMC week options and the scheduled event
The Federal Reserve publishes its meeting schedule well in advance, so the announcement is not a surprise in timing, only in content. On decision days the statement is typically released at 2:00pm Eastern, and the press conference typically begins around 2:30pm Eastern. Check the Fed calendar for the meeting and statement time before you trade, because schedules and formats can change.
That gap between the two events matters for options. The statement can move prices in seconds, and the press conference can move them again, sometimes in a different direction. Option prices have to account for both windows, which is one reason the market treats the whole afternoon differently from a normal session.
Implied volatility around the FOMC
Implied volatility is the market’s pricing of how much the underlying might move, built into each option’s premium. When a known event sits inside a contract’s lifetime, sellers tend to ask for more and buyers tend to pay more, so implied volatility is typically bid up in the days leading into the announcement. This is the IV build.
After the event, the uncertainty is resolved. The question of what the Fed will say is replaced by what the Fed said. Implied volatility can then fall quickly, often described as an IV crush, even when the underlying moves. A buyer of an option can be right about direction and still see the premium shrink if the drop in implied volatility outweighs the price move. A seller faces the mirror image, where the premium collected was inflated going in, but a large move can still produce a loss bigger than the premium.
None of this is a rule that applies every time. How much implied volatility builds, and how much it falls, depends on the underlying, the expiration, and what else is happening in the market. Treat it as a tendency to understand rather than a pattern to count on.
Options before Fed meeting day: same-day expirations
An option that expires on decision day has very little time left, so almost all of its remaining value is tied to where the underlying sits at the close. The announcement lands in the middle of that short window. A contract near the money can swing from most of its value to almost none within minutes, and a contract far from the money can suddenly become relevant.
This is why same-day expirations are the most exposed to the event. There is no time to wait for a position to recover after a sharp move, and the bid-ask spread can widen right around the release, which makes entering and exiting more expensive. The speed also compresses the time you have to think. If you decide to hold a same-day contract through 2:00pm, decide the maximum amount you can lose before the clock starts, not after.
Weekly vs monthly expirations in an FOMC week
Weekly contracts that expire later in the same week contain the announcement and some days of aftermath. Their prices include the event premium, and they keep some time value after it passes, so a decline in implied volatility affects them but does not end the contract. Contracts that expire on a Friday after a Wednesday decision, for example, still have a couple of sessions in which the market digests the result.
Monthly expirations, and anything further out, spread the event across a much longer life. One announcement is a small part of the total time, so the effect of the IV build and decay on the premium is typically smaller. The tradeoff is that longer-dated contracts cost more in absolute terms and respond more slowly to a quick move. Which one fits depends on whether you want exposure to the event itself or exposure to the direction over a longer period. Those are different goals, and mixing them up is a common source of confusion.
Check the contract specifications and your broker’s rules for expiration times, settlement style, and exercise handling, since these differ by product.
Sizing and being flat as legitimate choices
Position size is the control you have over an event you cannot predict. Smaller size means a surprise move or a drop in implied volatility is survivable. Some traders reduce size into the announcement, some hold their normal size with a defined maximum loss, and some close positions before 2:00pm and re-enter once the first reaction settles. All three are legitimate. Being flat through the event is not a failure to participate, and it can be the most sensible position when the setup is unclear.
Defined-risk structures such as vertical spreads cap the loss, though the premium and the effect of implied volatility on each leg still need to be understood before the event, not during it. Trading involves risk of loss, and an event week can produce larger and faster swings than a normal week.
ILLUSTRATIVE example with round numbers, not a real trade or a recommendation. Suppose an at-the-money option on a hypothetical stock is quoted at $2.00 the day before an announcement, with $1.50 of that coming from the normal expected movement and $0.50 coming from extra event premium. If the stock ends the next day unchanged, the event premium can disappear and the option may be worth about $1.50 or less, even though price did not move against the holder. If the stock moves enough, the gain in intrinsic value can outweigh the lost event premium. The numbers are invented to show the mechanism.
Building a plan before the announcement
A simple plan has four parts. First, note the date and the 2:00pm Eastern statement time from the Fed calendar. Second, choose the expiration on purpose, knowing how much of the premium is event premium. Third, set the size so the worst case is acceptable. Fourth, decide in advance whether you will hold through 2:00pm, exit before it, or wait until the press conference is over. Writing these down reduces the urge to improvise while prices are moving.

Summary
An FOMC announcement is a scheduled event, and options that expire soon after it typically carry extra implied volatility that can fall afterward. Same-day contracts are the most exposed, weekly contracts hold part of the effect, and monthly contracts dilute it. Choosing the expiration deliberately, sizing for the worst case, and staying flat are all reasonable ways to handle the week.
