The mood on commodity trading desks undergoes a significant shift by Friday afternoon, as traders transition from focusing on making profits to managing risk. With the inability to adjust or rebalance bets over the weekend, traders must tolerate risk for 48 hours until markets reopen on Sunday evening. However, the rise of perpetual futures contracts in the cryptocurrency market has introduced a new paradigm, enabling traders to hedge their positions and adjust their bets around the clock. This development has significant implications for the traditional 'weekend effect' in short-dated West Texas Intermediate crude options, where implied volatility is typically depressed on Fridays.

The availability of perpetual contracts allows traders to capture profits over the weekend, rather than simply sitting on their positions. While institutional traders have yet to fully embrace this new opportunity, the growth of perpetual futures trading volume and the increasing participation of retail traders are driving a shift towards 24/7 trading.

As the financial infrastructure adapts to support continuous trading, the distinction between weekdays and weekends is becoming increasingly blurred, and the traditional weekend trading habits of Wall Street are being rewritten.
