What's Driving the Move
Today's FX agenda is not dominated by macro data or central bank decisions, but by the mechanics of options expiry — an underappreciated yet consistent pattern in currency markets.
When a large volume of options contracts approaches expiry at the same strike level, a fairly predictable dynamic emerges: market makers and dealers — typically large international banks — sit on the other side of these contracts and must continuously neutralize their delta and gamma exposure. The closer spot trades to the strike price, the more aggressively they must buy or sell the underlying currency. The result, well-documented in the literature and by analysts such as Giuseppe Dellamotta at InvestingLive, is what is known as price pinning: the market is "pulled" toward the strike price and held there until expiry.
For EUR/USD, the situation is particularly interesting today. The three strikes — 1.1725, 1.1680, and 1.1650 — are spread across just 75 pips, meaning spot is simultaneously within the gravitational field of multiple expiries. Analysts at Refinitiv Eikon and Reuters Markets note that such tightly clustered expiries can compress the effective trading range and make intraday breakouts unreliable until the cut passes.
The AUD/USD expiry at 0.7130 with AUD 874 million is particularly worth noting. AUD has traded in a relatively tight band in recent days, and an expiry of this size will likely function as a gravitational anchor. If spot is within 30–50 pips of 0.7130 heading into 10:00 ET, there is a high probability that price action converges there.
For USD/CAD, the situation is more complex: two expiries 270 pips apart (1.4020 and 1.3755) do not represent pinning, but rather a market with diverging views on direction. Here, volume is likely to concentrate around whichever strike spot is closest to heading into the cut.
The broader market backdrop is risk-on. BTC is trading around $79,300 (as of August 25, 2026, per system data), indicating that capital markets are generally in a risk-seeking mode. The DXY dollar index is a key variable here — a strong dollar will pull EUR/USD away from the upper strikes, while dollar weakness could anchor the pair closer to 1.1725.
Key Figures
Currency Overview — Today's Expiry Map
EUR/USD
The three strikes at 1.1725 (€729M), 1.1680 (€800M), and 1.1650 (€632M) total €2.16 billion. The densest cluster around 1.1680 makes it the "magnetically strongest" strike. If spot trades between 1.1655 and 1.1705 heading into the cut, traders should expect compressed volatility and limited trending opportunities. A level break after the cut — particularly above 1.1730 or below 1.1635 — could, however, produce a brief volatility spike as dealer hedging unwinds.
AUD/USD
0.7130 with AUD 874 million is today's dominant single strike by volume. AUD/USD has been supported by commodity strength and Chinese stimulus signals, but the options wall here may limit near-term upside. If 0.7130 is broken decisively after the cut, it opens the door for a faster move.
USD/CAD
The two strikes at 1.4020 and 1.3755 tell an interesting story about market uncertainty around CAD direction. This is not pinning — it is a polarized market. Oil prices (WTI and Brent) and Bank of Canada signals will be the actual drivers here; the options expiry merely provides context for intraday ranges.
USD/JPY
159.00 with US$345M is moderate, but JPY volatility could be amplified by any comments from Bank of Japan officials. The Bank of Japan has kept its policy under review since its historic rate-hiking cycle, and the market is on alert. 159.00 is a psychologically significant level.
USD/CHF
0.8020 with US$309M is the smallest expiry today, but CHF traditionally functions as a safe haven — if the risk environment shifts abruptly heading into the New York open, this level could be activated faster than its size would suggest.
Technical Picture
EUR/USD is currently in a medium-term uptrend after breaking above the 1.15 resistance level earlier this summer. RSI on the daily chart was last reported around 58–62, placing it squarely in "bullish momentum" territory without being overbought. The nearest support is 1.1635 (coinciding with the 10-day EMA and the bottom of the options cluster), while resistance sits at 1.1750 — just above today's uppermost strike.
AUD/USD has technical support at 0.7090 (former resistance, now support), while 0.7130 represents a potentially dual function: technical resistance and today's largest options strike. The convergence of these two levels further reinforces the gravitational effect.
USD/JPY is technically sensitive around 159.00 — the level has repeatedly served as support/resistance throughout 2025–2026. Options market volume is moderate here, but the technical significance of the level makes it worth monitoring.
For USD/CAD, the two strikes point to a market in a holding pattern — not waiting on options expiry, but on the next catalyst. The technical trend is flat to mildly USD-bullish, with support around 1.3720 and resistance at 1.4080.
"When market makers hedge gamma aggressively into an expiry, they are not buying and selling because they believe in a direction — they are price-agnostic. That is precisely why price gets pinned." — Giuseppe Dellamotta, InvestingLive
What to Watch
Today (August 25):
- 10:00 ET (16:00 CET): New York Cut — expiry of all options listed above. Monitor EUR/USD, AUD/USD, and USD/CAD in the first 15 minutes after the cut for a volatility flare-up
- EUR/USD levels to watch: Support 1.1635 / Resistance 1.1750. Breaks in either direction are meaningful
- AUD/USD: Keep an eye on 0.7130. If the pair closes above this level on the daily chart after the cut, bullish momentum is confirmed
This week:
- Jackson Hole aftermath: Fed speeches and any policy signals from last weekend's symposium will continue to shape DXY and thus the EUR/USD trajectory
- PCE deflator (Friday, August 29): The Fed's preferred inflation gauge. An upside surprise = stronger dollar, which would test support at all of today's EUR/USD strikes in reverse
- Next major FX options expiry: Roll to the monthly expiry at end of August — typically the most significant, with far higher notional volume
- Bank of Japan: Any speaking engagements or meeting minutes could trigger JPY volatility around the 159.00 level
- Oil prices: A direct driver for CAD — OPEC+ signals and EIA inventory data are critical context for USD/CAD direction between the two strikes
