As we approach the end of June, a well-known phenomenon among FX traders is once again coming into focus: when currencies have diverged significantly over the course of a month or quarter, we often see a technical correction into the final trading session, with partial pullbacks in the pairs that had previously moved the most.
This end-of-month or quarter pattern is not random. It is the predictable result of recurring institutional flows. Recently, the US dollar has notably weakened against most major currencies. As a result, we could anticipate a modest bounce in the dollar to close out the month and start the new week, as various participants are likely to adjust their positions accordingly.
Performance of FX futures contracts from Sunday, June 1 to Friday, June 27:
Swiss Franc +3.71%
Euro +3.61%
British Pound +1.95%
New Zealand Dollar +1.58%
Australian Dollar +1.50%
Canadian Dollar +0.67%
Japanese Yen +0.16%
Performance of FX futures contracts from Tuesday, April 1 to Friday, June 27:
Swiss Franc +10.73%
Euro +8.40%
New Zealand Dollar +6.90%
British Pound +6.26%
Canadian Dollar +5.23%
Australian Dollar +4.80%
Japanese Yen +3.68%
These figures illustrate a broad-based decline in the dollar during June and over the entire second quarter. Historically, such imbalances open the door to late-stage adjustments, with currencies that have risen sharply often seeing modest technical pullbacks. This is a setup closely monitored by FX traders, who view it as a high-probability opportunity based on a pattern that is rare, but remarkably consistent.
FX rebalancing: mechanics and market players
At the heart of these adjustments lies one key concept: rebalancing. This is the process by which institutional players, pension funds, insurers, central banks, passive managers, bond funds, corporates adjust their FX exposures to stay in line with the targets defined in their mandates.
Every month, the value of their assets (equities, bonds, alternatives) and currency holdings fluctuate. If a currency appreciates sharply, its weight in the portfolio may become too high. Conversely, if a currency weakens, exposure might fall below target. Rebalancing involves buying or selling FX to return to those target allocations.
This process is recurring, predictable, and usually concentrated in a narrow window, the final hours of the trading month, just before the London 4pm fix. Quarter-ends tend to be even more pronounced, as many investors revisit long-term strategic allocations at that time.
Many of these adjustments are driven by systematic models using fixed thresholds, which adds to the consistency and timing of these flows.
Ideal setup: low volatility, high impact
June 2025 ends in a particularly calm environment: equity markets are stable or even rising, and the VIX is trading near its yearly lows, signs of a quiet and balanced market that favors more technical trading. This context is favorable for strategies aiming to take advantage of rebalancing effects, as in the absence of new announcements or unexpected events, these adjustments are likely to have a tangible impact on prices.
Conversely, in a more volatile market environment, such adjustments could be drowned out by larger flows (such as a flight to quality), thus having a reduced or even negligible impact.
FX options: another layer of flows
Another important factor on Monday, June 30: a large number of FX options expire at 10am New York (3pm London). These expiries cover several major pairs, with significant notional amounts concentrated near current spot levels.
According to what is currently being whispered on trading desk chat rooms, we expect the following large expiries:
When spot approaches these strikes, option holders or sellers may intervene to "pin" prices, based on their delta exposure. This behavior can amplify technical price movements in the hours before expiration.
When these heavy expirations align with month/quarter end rebalancing flows in a quiet, low-volatility market, it creates a strong potential cocktail for tactical moves, conducive to a dollar rebound into the fix.
How to trade the pattern effectively
Here’s a simplified roadmap to navigate this recurring pattern:
In short...
Quarter/month end FX rebalancing is one of the few market events where anticipated institutional flows can create repeatable, high-probability trading opportunities. These flows stem from real portfolio needs and systematic re-hedging, and are often amplified by option expiries and technical positioning.
This setup provides a great educational case study for any trader seeking to better understand hidden FX dynamics. There’s no secret indicator or crystal ball here, just a solid grasp of structural flows and timing.
From a personal standpoint, after over 20 years trading currencies, this strategy remains one of my favorites: simple, effective, and highly instructive. I encourage you to study it closely, and observe its behavior during upcoming month-end windows.

How to trade the pattern effectively
Here’s a simplified roadmap to navigate this recurring pattern:
- Identify monthly or quarterly extremes: look for the currencies that gained or lost the most over the period;
- Assess the market environment: a low VIX, no major data or central bank events, meaningful trends, and significant options expiries are ideal conditions;
- Use liquid and transparent instruments: Sep 2025 FX futures (standard, e-mini or micro) are currently the most suitable products for active positioning
- Set realistic expectations: aim for a 0.5% to 1.0% pullback, not a full-blown trend reversal
- Manage risk properly: as with any strategy, always use a stop-loss. This is quantitative trading, not fortune-telling. If the USD continues to weaken despite the setup, be ready to exit swiftly.
In short...
Quarter/month end FX rebalancing is one of the few market events where anticipated institutional flows can create repeatable, high-probability trading opportunities. These flows stem from real portfolio needs and systematic re-hedging, and are often amplified by option expiries and technical positioning.
This setup provides a great educational case study for any trader seeking to better understand hidden FX dynamics. There’s no secret indicator or crystal ball here, just a solid grasp of structural flows and timing.
