The Importance of Expiry Levels

The USD/CHF expiry is at the 0.8000 level. This could provide some resistance to price changes, but with recent downward movement in the pair, momentum remains inclined towards further decreases. The month-end dynamics could counterbalance these expiries.

Overall, expiries might influence European morning trade marginally. As the month end nears, flows related to the dollar will gain prominence. For detailed guidance on using this data, additional resources are available to explore.

The current levels highlighted—particularly those in EUR/USD—suggest that option-related flows might create temporary pauses or bumps in otherwise directional price action. Those 1.1700 and 1.1750 strikes, while not technically aligned, aren’t by any means random. They reflect where positioning is dense and where premiums lie vulnerable to quick reversion. It’s not about trend, but about magnets that pull spot temptingly close when liquidity thins near fixings.

We’ve seen it before: when dates and levels collide like this, activity slows just enough to stifle momentum. Such pauses aren’t structural signals; they’re short-lived tensions between open interest and real money flows. Though the levels themselves might not act as resistance or support in the usual charting sense, they can shape the way intraday ranges form—especially into the 4 pm London fix or during early trade in Europe.

The Role of Dollar-Based Flows

Looking at yen trades, the 143.85 strike serves more as a proximity flag than a turning point. Last week’s lows flirted with this area, making it psychologically charged even without a technical confluence. Expiry dynamics here may not overpower pricing imbalance driven by the broader dollar narrative, but they can divert traders just long enough to stall progress or amplify whipsaws, particularly in illiquid hours or during demand surges.

Meanwhile, the Swiss franc pairing, with strikes congregating around 0.8000, lines up cleanly with recent directional bias. The trend downwards had already been gathering strength; option interest here could add friction, but it shouldn’t reverse movement unless something external tilts the table. It’s one of those readings where expiry keeps the edge busy but won’t make or break a move by itself.

As we move into the early trading week and approach the month’s close, the influence of dollar-based order flows becomes more material. We typically witness increased activity from real-money accounts during this time—not speculative, but position-driven. It leads to a higher chance of friction around dollar pairings. These flows mix with the pressure of resting options, occasionally giving traders a cleaner line into next month’s pricing.

So what does this mean as we plan our sessions? Maintain the lens on expiry clusters, not as definitive turning points, but as pressure zones. Map intraday strategies around areas of congestion where strikes align with upcoming fix times, particularly in thinner trading sessions before US markets digest fresh impulses. If a spot rate drifts toward a high-volume expiry, the likelihood of a sticky behaviour near that level goes up—enough to recalibrate tight stop placements or reconsider short-range scalp entries.

Option-related pins might not matter when macro trends are strong, but at the turn of the month—with frequent rebalancing—they deserve extra attention. We see patterns emerge during these windows, especially when risk-adjusted order books force large players to cover ahead of fixes. That’s how range builds turn into false breaks, or how momentum stalls with no headline catalyst—expiries sneak in, unannounced, and quietly absorb price action near well-flagged numbers.

Keep in mind that these options are set to expire not just today but tomorrow as well, meaning today’s pricing behaviour may bleed directly into early Tuesday trade. That’s often when expiry hedges unwind and leave traces just ahead of the next reset. Not all levels are created equal, and some may draw more volume as hedging litters the early part of the session. Hence, we watch and re-watch those expiry zones—but we don’t anchor bias to them. They act more like rip currents just below the surface: visible if you look close, and strong only if you’re already caught in one.

Trading into a week that ends a month requires adjusting to shifts driven by rebalancing orders collapsing into option-driven gravity. That’s the rhythm to watch for—a few hours of slippage magnified by short-dated protection unwinding faster than expected. We’ve already seen how a build-up of option volume into week-closing windows can change intraday rhythm. Now we ride that same tide, expecting a little more stickiness as expiry pressure comes into focus.
