There's little to excite markets before week's U.S. Labor Day holiday, which should keep pressure on very short-dated expiry options for .

EUR/USD consolidates by huge strike expiries in the mid/lower 1.11's. Benchmark 1-month expiry implied volatility increased from 5.3 to 6.65 since Aug. 16, but reverts sub 6.5 since. Benchmark 1-month expiry risk reversals reached their highest EUR call over put premium since 2020 at 0.4 on Monday, before slipping to 0.2.
USD/JPY is said to be long of JPY calls via various knock-out type option positions, which has taken the 1-month risk reversal premium back to 2.1 from 2.5. That's still high and highlights the perceived risk of more USD/JPY losses.
GBP/USD 1-month implied volatility holds 7.3 from a mid-August low at 5.9, but although erasing their long-standing downside strike premium, benchmark 1-month expiry risk reversals weren't able to generate any topside strike premium.
AUD/USD 1-month expiry implied volatility is in the middle of its July-August 7.5-11.4 range and more vulnerable to weakness as spot gains falter above 0.6800. Risk reversals lower but retain a long standing downside versus upside strike FX volatility risk premium.
