The FX option expiries for 11 September include EUR/USD at the 1.1700 level, which may act as a magnet for price action ahead of the European Central Bank meeting and the US Consumer Price Index report. These are key events for the markets, indicating limited movement before their release.
Additionally, there is a USD/JPY expiry at the 147.50 level, near the current 100-hour moving average of 147.51. However, this is unlikely to impact price action significantly, as the pair continues to range. The US inflation data later in the day is expected to be the primary influence on market behaviour.
Market Focus and Expectations
We see the option expiry in EUR/USD at 1.1700 could act as a magnet for price this morning. However, the real focus is on the US CPI and ECB announcements later today, which will set the tone for the coming weeks. Markets are currently pricing in a 70% chance that the Federal Reserve will hold rates steady at their next meeting, a probability that will shift dramatically after the inflation data is released.
The US CPI report for August is expected to show headline inflation cooling to 3.1% year-over-year, down from 3.4% in July. A number in line with or below this forecast would likely reinforce the view that the Fed’s tightening cycle is over, putting downward pressure on the dollar. Conversely, any upside surprise would reignite bets on another rate hike before year-end and cause significant market volatility.
For USD/JPY, the 147.50 expiry level is of little importance compared to the influence of US interest rate expectations. Looking back to the 2023-2024 period, we saw heavy official warnings and intervention fears in this same price zone, but the dynamic has since evolved. With the Bank of Japan still maintaining a broadly accommodative policy, the path for the pair will be determined by whether US inflation data can push Treasury yields lower.
Implied Volatility and Market Reactions
Given the dual high-impact events, implied volatility in the FX options market has risen, with one-week volatility for EUR/USD jumping to over 8.5% this morning. This suggests traders are bracing for a decisive move out of the recent ranges. We should therefore be cautious of choppy price action around the 10am New York cut, as the larger market players position themselves for the main events later in the day.
