CHF/JPY Shows Strong December Returns: +1.59%, 75% Win-Rate

Monthly Bias Map

Understanding the seasonal patterns of CHF/JPY can provide traders with valuable probabilistic insights. Over a 20-year period, December stands out with an average return of +1.59% and a win-rate of 75%, suggesting a strong upward bias. In contrast, the current month of September has a neutral profile, averaging a -0.27% return with a 50% win-rate. Such patterns are shaped by factors like year-end portfolio rebalancing and tax-related flows, which can influence currency dynamics.

Best and Worst Months

December emerges as the most favorable month for CHF/JPY. The combination of a high average return and a strong win-rate suggests that seasonal factors, such as end-of-year financial reporting and rebalancing, may drive demand for the Swiss Franc. Conversely, July presents the most challenging conditions, with an average return of -0.64% and a win-rate of only 45%. This negative performance could be attributed to mid-year shifts in risk sentiment or macroeconomic adjustments, which often lead to heightened volatility and risk aversion during summer months.

Day-of-Week Tilts

Although not as pronounced as the monthly effects, there are some day-of-week tendencies worth noting. Mondays have a slight positive bias with an average return of +0.028% and a 36% win-rate. However, the overall day-of-week effects show limited predictability, as indicated by the mixed performance of Wednesdays and Tuesdays, which exhibit negative and positive biases respectively, but with win-rates around 31%. Such variability suggests that daily movements may be more influenced by short-term news and events rather than structural seasonality.

Where Seasonality Breaks

It's crucial to recognize that seasonality provides probabilistic priors, not certainties. Macroeconomic shocks, such as central bank interventions or geopolitical events, can disrupt these patterns. Additionally, regime changes, such as shifts in monetary policy or economic cycles, can alter the underlying dynamics that drive seasonal trends. Traders should incorporate other analytical tools and remain vigilant to changes in the broader economic landscape.
