Bitcoin Options Expiry: What It Costs Crypto Futures Traders

At 07:59 UTC on a Friday, a perp chart can look perfectly calm. At 08:00 it can start printing candles that belong to a different day. Sometimes the reason isn't a headline at all — it's a pile of options contracts settling on the same minute.

Most coverage asks up or down? This piece asks the question that lands on your account statement: what does an options-expiry morning cost a futures trader, whichever way the price goes?

The date to circle

Deribit's monthly Bitcoin options expiry is Friday, October 30, 2026 at 08:00 UTC. According to Crypto Briefing, it covers 140,844 BTC of contracts — about 35% of all Bitcoin options open interest on Deribit. At roughly $86,000 per BTC that is a notional of roughly $10.7–11.3 billion.

Two details traders are watching:

• the largest single strike is the $95,000 call, around 24,000 BTC of open interest (about $2.1 billion notional)
• the "max pain" level — the theoretical price where option sellers lose least — sits around $78,000–79,000, with calls outnumbering puts roughly 2 to 1

Max pain is one hypothesis among several about how expiries behave, not a magnet you can rely on. We take no view on direction here.

One clarification: BingX, OKX and MEXC do not offer options. The expiry happens on Deribit. What reaches you is the second-order effect — when large options positions are hedged and settled around one timestamp, the perp market can see sudden swings and thinner order books. The costs below are what that does to a futures account.

Cost #1: the fees you pay for reacting

On a quiet morning you open a position and close it. Around a big expiry, many traders do something else: get stopped out on the first spike, re-enter on the reversal, cut again when it wobbles. Each exit and re-entry is usually a market order — a taker fill.

Here is how the exchanges loweef tracks compare:

Cost #1: the fees you pay for reacting

Exchange	Total rate	Welcome boost	Effective taker
BingX	60%	70%	0.0200%
OKX	50%	60%	0.0250%
MEXC	50%	—	0.0200%

Taker fees are charged on the full position size, not on your margin. As an example, per $10,000 of position:

• every 0.01% of fee = $1
• a round trip (in and out) at a 0.05% taker rate = 0.10% = $10
• three whipsawed round trips in one morning = $30 — on a position you might have opened with $1,000 of margin at 10x

At 10x leverage, $30 in fees is 3% of your margin gone before the trade has made or lost a cent. Volatility doesn't just move the price — it multiplies how often you pay the fee.

What actually helps: a limit order that rests in the book pays the maker rate, which is lower on every exchange in the table — maker vs taker fees, explained →. And on whatever you do pay, a fee payback returns 60% of it on BingX, at the current combined rate. It covers fees only — not losses or liquidations. Run your own numbers in the calculator →

Cost #2: funding around the 08:00 UTC settlement

Perpetual futures charge funding between longs and shorts. On BingX and OKX the default settlement times are 00:00, 08:00 and 16:00 UTC — every eight hours.

Notice what that does with this expiry: 08:00 UTC is both the options settlement and a funding settlement. If you hold a position through that minute, you pay or receive funding at the same moment the market may be at its jumpiest. If traders crowd one side during the swing, the next rate for that side can climb — hold the crowded side through 16:00 and you pay it.

Funding is easy to underestimate because the rates look tiny. What funding actually costs in dollars →

Cost #3: the distance to your liquidation price

None of this is a fee, but it is the most expensive line on an expiry morning. A position at 25x leverage sits roughly 4% from liquidation before fees; at 50x, roughly 2%. A single violent candle can cover that distance and come back before you've refreshed the page.

The exact liquidation price depends on the exchange's maintenance margin rules and your fees, so check it on the order screen before 08:00 UTC — not after.

A pre-expiry checklist (costs only, no calls)

• Know the time in your zone: 08:00 UTC, October 30.
• Check the funding rate and the next settlement time on the contract you hold — 08:00 UTC is a settlement.
• Decide in advance whether you'll use limit orders (maker) or accept taker fees on fast exits.
• Look at your liquidation price with the leverage you actually use.
• Count your round trips afterward — that's where expiry-morning fees hide.

The direction is anyone's guess. The costs aren't.
