Oil traders faced one of the most volatile sessions in history when Brent crude swung 38.6% intraday, with prices surging to a 28.9% high before plunging 9.7%. While the dollar-value swings grabbed headlines, percentage-based volatility tells a different story. The ICE Brent Futures data reveals that Monday's session ranks among the wildest in percentage terms, though not the craziest ever.

Historical context matters: throughout the 1990s, crude typically traded under $20 per barrel, while the 21st century average hovers around $60. This inflation-adjusted baseline means dollar-value swings naturally appear more dramatic today. The early pandemic days, particularly April 22, 2020, still hold the crown for relative volatility, occurring just two days after WTI futures briefly turned negative. That session saw extreme price movements that dwarfed Monday's percentage swings.

For veteran traders who weathered the 1980s and 1990s markets, Monday's session might feel anticlimactic. The article suggests that without modern trading aids like energy drinks and power naps, those earlier sessions demanded different survival strategies. While dollar-value records fall regularly in today's higher-priced market, the true measure of trading madness remains the percentage swings that defined the pandemic's early chaos.
