USD/BRL

On Wednesday, June 16, 2026, an event is taking place in the foreign exchange market that most ordinary people will not even notice. But those who trade currencies know: today, large FX options are expiring. Billions of dollars, euros, yen, pesos, yuan, and reais may be exercised, not exercised, or rolled over. And depending on what happens, exchange rates could shift by tenths of a percent—or more.

This is not just a technical detail. It is a key market moment. Because options are both insurance and speculation at the same time. When they expire, the market loses support or resistance levels. Prices can move sharply. Traders holding positions may be forced to close them.

And today, on Wednesday, large options expire across several currency pairs. Let’s start with USD/JPY. The largest option is worth $1.09 billion with a strike at 158.00. Almost a billion dollars! What does this mean? The trader who bought this option has the right to buy or sell dollars at 158 yen per dollar. If the market is above 158, the option is in the money. If below, it is worthless.

In addition, options expire for $749.6 million at 157.25 and $691.1 million at 158.50. There are also USD/CNY options worth $1.8 billion at a strike of 6.7928. USD/BRL options worth $767.5 million at 5.1100. EUR/USD options worth nearly 1 billion euros at 1.1450. AUD/USD options worth 933.3 million AUD at 0.6650. USD/MXN options worth $629.5 million at 17.24.

All of these expire today. And they may affect markets.

But that’s only today. On June 18 (tomorrow), even larger options expire: EUR/USD options worth 8.73 billion euros at 1.1500! Yes, nearly 9 billion euros. No joke. And USD/JPY options worth $1.79 billion at 155.00. And USD/CAD options worth $884 million at 1.3735.

These are truly large...

Tuesday’s New York cut. For most people, it’s simply the close of the U.S. trading session. For FX traders, it’s a moment of truth. Options contracts worth billions of dollars are set to expire, and these expiries often exert an almost gravitational pull on spot exchange rates, drawing them toward specific levels. Market makers hedging their positions will do everything possible to keep prices near major strikes. Once the options expire, however, those anchors disappear—and the market may make a sharp move. Let’s look at the key currency pairs and where the traps are set today.

EUR/USD: Nearly €2 Billion at 1.1850

The main magnet for the euro today sits at 1.1850, where options totaling €1.82 billion are due to expire. This is not just a large expiry—it is a gravitational anomaly. The spot rate could be pulled toward this level during the final hours before the New York cut.

Additional anchors include €1.51 billion at 1.1750 and €1.27 billion at 1.1700. Together, these levels create a web of attraction within which the pair may fluctuate. Market makers will actively manage their positions to minimize payouts on expiring contracts. If EUR/USD trades below 1.1850, they may buy euros and push the price higher; if it trades above, they may sell and pull it back toward the strike. This is classic options-related gravity, making sharp moves before expiry less likely.

Notably, an even larger expiry is scheduled for Wednesday: €2.47 billion at 1.1710. This suggests that even after Tuesday’s cut, the market will not gain complete freedom—the next anchor is already waiting.

USD/JPY: 160.00 Is the Red Line

For dollar-yen, the primary magnet is 160.00, where $1.59 billion in options expire. The 160 level is the same red line that triggered large-scale foreign exchange intervention by the...
