At 9:47 AM Eastern on a Friday in June, the EUR/USD order book thins. Market makers pull quotes, widen spreads, and prepare for the 10:00 AM New York cut — the daily window when standardized FX options expire against a single reference fixing. On 8 June, the wires will publish a list of strikes and notional amounts, usually expressed in billions of dollars per currency pair. Beginners read those lists and assume the numbers predict direction. The numbers do not predict direction. They describe a gravitational field around specific price levels, and that field carries a measurable cost in spread — a cost most retail traders never count.
What Is the 10am New York Cut and Why Does 8 June Matter?
The 10am New York cut is a convention. It is the time of day at which the largest pool of standardized over-the-counter FX options are written to expire. Spot trades against the prevailing rate at that fixing window, and any in-the-money option holder either exercises into spot or lets the contract die.
8 June matters only because it is a date on which expiries are scheduled. There is no calendar magic. The first Friday of any month, end-of-month rolls, and quarter-ends concentrate larger notional sizes because corporate hedgers and institutional desks align their hedging tenors to those points. A Wednesday mid-month — which 8 June can fall on in some years — tends to see a thinner book. The relevance of any particular date is purely a function of what notional is sitting at what strike on that day's tape.
A beginner should treat 8 June as a label. The mechanics described in this article apply to every 10am NY cut on every business day of the calendar.
Where Do the Published Expiry Levels Actually Come From?
The lists circulated each morning by financial wires originate from option dealing desks at the largest interbank market makers. These desks know their own book — the strikes, notional sizes, and expiry dates of every option they have written or bought. They share approximations of that book with brokers and news vendors, who aggregate the data and publish a summary.
The published figures are not regulatory disclosures. They are not exhaustive. A 1.5 billion EUR strike at 1.0800 reflects the visible portion of the dealer-side book; bilateral trades between corporates and a single bank may never enter the wire. The figures are also rounded — a number printed as "EUR 1.2 bn" might be 1.18 or 1.24.
For a beginner, the operational point is this: the list is an indicator of where dealer attention sits, not a measurement of total open interest. Two primary documents from the post-2001 electronic-trading era frame this. Interbank-platform records show one snapshot of the book; corporate hedging mandates filed in regulatory disclosures show another. The two rarely reconcile cleanly, and reconstructing the difference is part of what desk traders do.
How Does a Notional Figure Translate Into Spot Pressure?
The notional of an option is the face value of the currency it controls. A 1 billion EUR option struck at 1.0800 references 1 billion euros against 1.08 billion US dollars. If the option is at-the-money near expiry, the dealer holding it is delta-hedging — buying or selling spot continuously to neutralize directional exposure as the option's sensitivity to spot moves toward 1 or 0.
The pressure on spot comes from this delta-hedging activity. As 10am approaches and an option's strike sits close to the prevailing spot rate, dealers must trade spot in increasing size to keep their book flat. If the strike is above current spot and the option is a vanilla call, dealers are typically short delta and buying spot as expiry approaches. If below, selling. The aggregate of these flows is what creates the "pull" toward the strike.
The arithmetic for a beginner: notional × delta × hedge frequency = spot flow per minute. A 1 billion notional, with delta drifting from 0.40 to 0.60 over the final hour, generates roughly 200 million in residual hedging — distributed across the order book over sixty minutes.
Why Do Spot Rates Get "Pinned" Near Big Strikes?
Pinning is the observable phenomenon where spot drifts toward and then sits near a heavy strike in the minutes before expiry. The mechanism is mechanical, not behavioral. Dealers short gamma at a strike sell when spot moves above it and buy when spot moves below — the reverse of momentum trading. That action damps movement around the strike.
The pin is strongest when three conditions hold. First, the strike is close to current spot. Second, the notional is large relative to typical hour-by-hour volume in the pair. Third, dealers are net short the option, meaning they are gamma-negative and forced to hedge against direction. When dealers are net long the option, the same notional produces the opposite effect — spot becomes more volatile near the strike rather than less.
The retail trader rarely knows which side the dealer book is on. The published expiry list reports the strike and the notional but not the direction of dealer exposure. Treating every large strike as a pin candidate is the most common beginner mistake.
What Happens to the Bid-Ask Spread in the 15 Minutes Before 10am?
Spreads widen. This is the cost the article was written to expose. From 9:45 AM Eastern onward, electronic market-maker algorithms detect the elevated risk of a fixing-driven price spike and increase their quoted spread to compensate.
Pre-2001, when forex spot dealing was conducted by voice on a manual market, spreads in major pairs sat at 3 to 5 pips outside the cut window and could blow out to 8 or 10 pips in the final minutes before a fixing. Post-2001, with the rise of electronic communication networks, baseline spreads compressed to 0.1 to 0.5 pips on raw ECN feeds — but the relative widening at the cut remained. A 0.1 pip EUR/USD spread can move to 0.4 or 0.6 pips at 9:55 AM. That is a fourfold to sixfold cost increase concentrated in fifteen minutes.
IC Markets Raw, Pepperstone Razor, FXCM Active Trader, and Tickmill Pro all quote spread-plus-commission models on ECN feeds. The commission is fixed; the spread is what widens. A round-trip cost that runs 0.6 pips off-cut becomes 1.4 pips through the cut on the same pair.
Can a Beginner With 100 USD Realistically Trade Around an Expiry?
No. The arithmetic forbids it. A 100 USD account at 1:30 leverage controls 3,000 USD of notional, or about 0.03 of a standard lot. One pip on 0.03 lots is 0.30 USD. A 1.4 pip round-trip cost in the cut window is 0.42 USD, or 0.42% of the account, on a single trade.
That is the visible cost. The invisible cost is what beginners miss: slippage on the fixing print itself. When spot prints the 10am fix, it can gap one to three pips relative to the bid offered fifteen seconds earlier. On 0.03 lots, that is another 0.30 to 0.90 USD lost. Total: between 0.7% and 1.3% per round trip, before any directional view pays off.
A trader needs an edge of more than 1.3% per trade just to break even on the cost of doing business in this window. Beginner retail rarely has it.
What Is the All-In Cost of Holding a Position Through the Cut for One Year?
This is the math teardown. We assume a trader with a 5,000 USD account, who places one round-trip EUR/USD trade through the 10am NY cut every business day. There are roughly 252 business days in a year.
Step one — position size. On a 5,000 USD account at 1:30 leverage with a conservative 2% risk per trade, the position is 0.2 standard lots. One pip on 0.2 lots is 2 USD.
Step two — spread cost per trade. Outside the cut, a raw ECN EUR/USD round-trip is approximately 0.6 pips total (0.2 pip spread × 2 sides, plus 0.2 pips of effective commission cost). In the cut window, the same round-trip costs approximately 1.4 pips. At 2 USD per pip, that is 2.80 USD per trade.
Step three — daily slippage. Assume an average 1.5 pip slippage on the fixing print. At 2 USD per pip, that is 3 USD per trade.
Step four — annual visible cost. (2.80 + 3.00) × 252 = 5.80 × 252 = 1,461.60 USD per year.
Step five — opportunity cost. The 5,000 USD account, if held in a one-year US Treasury bill at 4.2% in mid-2026, earns 210 USD. That is foregone.
Step six — all-in annual cost. 1,461.60 + 210 = 1,671.60 USD. As a percentage of the starting balance, 33.4%. The trader must generate 33.4% gross return per year on trade entries alone to break even.
That number does not include platform fees, market data subscriptions, internet redundancy, or the time spent staring at a screen for fifteen minutes a day, 252 times a year — sixty-three hours of unrecovered labor.
Which Expiry Sizes Are Worth Watching and Which Are Noise?
The threshold is conventionally one billion USD-equivalent notional in a single strike. Below that, the published figure is usually too small to overwhelm normal hour-by-hour flow in a major pair. EUR/USD trades roughly 1.0 to 1.3 trillion USD per day; a 500 million notional strike at the cut represents 0.04% of daily volume and rarely moves spot in any detectable way.
Above one billion, the strike begins to register. Above two billion, in a single major pair, the pin behavior becomes statistically observable in tick data. Above three billion, the cut window starts to develop a distinct microstructure — wider spreads, larger fill sizes, and a measurable price reversion after the fixing print.
Cross pairs and minors require different thresholds. USD/MXN, for instance, trades roughly 130 billion per day. A 300 million notional in MXN is proportionally larger than a 2 billion EUR/USD strike. Reading the published lists requires normalizing notional against the pair's typical liquidity, not absolute notional alone.
The published wire summaries rarely do this normalization. The reader has to.
What Would Change Our View on Trading the New York Cut?
We would reverse the conclusion if three conditions held. First, raw ECN spreads at the 10am cut compressed to within 1.2 times their off-cut baseline, rather than the current 4 to 6 times. That would require electronic market makers to price the cut as a low-risk event rather than a high-volatility window — possible only if fixing-print slippage itself fell below 0.5 pips on average.
Second, dealer-side option book direction (gamma exposure) became part of the published wire summary, not just notional and strike. Without knowing which side of the option the dealer holds, the pin direction is unknowable; with it, the cut becomes a tradeable event rather than a probabilistic guess.
Third, account sizes below 5,000 USD became economically viable through fractional pip pricing that scales spread cost proportionally to position size rather than fixing it at a per-lot floor. None of these three conditions hold in 2026. Until they do, the New York cut remains a window for institutional desks and the corporates they hedge for — not for retail accounts attempting to trade the published levels.
FAQ
What time is the 10am New York cut in other time zones?
The 10am New York cut is 3:00 PM London time in winter and 2:00 PM in summer when daylight saving differs by a week between the two cities. In Asia, it is 11:00 PM Singapore or Hong Kong time, and 12:00 AM (midnight) Tokyo time. The cut does not adjust for local holidays in any single jurisdiction — it follows the New York business calendar, so a US public holiday on a Monday means no cut that day even if London and Frankfurt are open.
Do all FX options expire at 10am New York or only some?
Only standardized OTC vanilla options struck against the New York fixing convention. A large portion of dealer-to-dealer flow uses this cut, but exotic options, barrier options, and bilateral structured trades between a corporate and a single bank may use custom fixings — the Tokyo cut, the London 4pm fix, or a bespoke time agreed in the trade confirm. The published wire lists capture only the 10am NY portion of the book.
Why do brokers like IC Markets Raw and Pepperstone Razor widen spreads at the cut?
Their pricing engines source liquidity from interbank market makers and ECN venues whose quoted depth thins in the minutes before the fixing print. Brokers pass through the wider raw spreads they receive rather than absorb the cost. The commission component of the spread-plus-commission model stays fixed; the spread component reflects whatever the upstream venues are quoting.
Is the New York cut still as significant in 2026 as it was in 2001?
Less significant in proportional terms, more significant in absolute. Daily FX option volume has grown substantially since 2001 alongside electronic trading, so a typical strike notional has scaled with the market. But spot liquidity has grown faster, meaning the relative size of a 1 billion strike against daily volume has shrunk. The cut remains a microstructure event; it is no longer the price-discovery moment it was in the manual-market era.
Can I see the published expiry list for free?
Partial summaries appear in financial press wire stories most mornings, typically published around 8:00 AM London time. Full granular lists with all strikes and notional sizes are paid distribution from professional terminals. The free public summaries usually cover only the three or four largest strikes per major pair, which is sufficient context for a beginner trying to understand the mechanics but not enough to actually trade against the book.
What is the difference between the New York cut and the London 4pm fix?
Different conventions, different uses. The 10am NY cut is the standardized expiry time for OTC FX options. The London 4pm fix is a benchmark spot rate used primarily by index funds and corporate treasury for end-of-day valuations and large rebalancing flows. Both create microstructure events around their respective windows, but the participants and motivations differ — option dealers at one, passive flow at the other.
