Iran Standoff Becomes This Week's Pivotal Trading Event

For six months the market ran a simple playbook around Iran headlines: Trump threatens, tensions spike, then he backs off and risk assets recover. That dip-buying pattern, nicknamed the 'TACO' trade on Wall Street, has driven positioning through most of the year.

September broke the pattern. The de-escalation that traders priced in didn't materialize on schedule, leaving portfolios exposed to a geopolitical event that no longer resolves on the old timeline.

For CFD and FX traders, this raises the stakes on any Iran-related headline this week — volatility spikes may not fade as quickly as they have in prior months, changing how stop-losses and hedges should be sized around the event.
