In a low-volatility environment, the FX options market presents an insightful perspective on where traders anticipate possible instability. Elevated FX volatility risk premiums surrounding specific expiries serve as indicators of perceived threats to market tranquillity — even when the current spot prices may appear relatively calm. For instance, following Friday’s U.S. jobs report, market participants have largely discounted the implications for one-week expiries, as dealers proactively repositioned their premiums to alternate dates amidst escalating concerns regarding a potential government shutdown. 

Despite an already subdued level of implied volatility, any additional decline could entice buyers interested in capitalising on improved reward-to-risk dynamics. A prolonged government shutdown could impede the release of critical economic data — including the Non-Farm Payrolls (NFP) report — thereby amplifying uncertainty in the markets. This increased uncertainty raises the attractiveness of long volatility positions, as traders seek to hedge against the possibilities of extended disruptions in economic activity and data dissemination.

Particularly notable is the USD/JPY one-week implied volatility, which has shown resilience against the backdrop of the broader decline in the dollar. This resilience reflects the heightened event risk associated with the upcoming LDP leadership election taking place on October 4. The two leading candidates in this election are perceived to have starkly different policy views, which could significantly influence Bank of Japan (BoJ) rate expectations and consequently affect the direction of the Japanese Yen (JPY). This situation helps maintain the related volatility premium at elevated levels.

Moreover, during the Friday to Monday timeframe, one-week expiry USD/JPY implied volatility surged from 7.8 to 9.8, indicating a notable increase in traders' uncertainty about the future price movements of this currency pair. Additionally, benchmark one-month implied volatility received extra support from events leading up to that Monday, reflecting traders' positioning in anticipation of two critical central bank occurrences — the Federal Reserve's policy decision set for October 29, and the Bank of Japan's statement to be released on October 30. This backdrop of significant upcoming events further underscores the heightened volatility landscape in the FX options market.
