Today is the single most important trading day since the US-Iran war began on Feb 28 (Day 87). Three words: Wait for the deal.
Near-term (today): Asia session takes pricing leadership. Nikkei 65,000+ all-time high — front-running the peace trade. US holiday reduces noise. Asia has unprecedented pricing power. Deal signed = Tuesday US opens with full catch-up rally + risk-on surge. No deal = Tuesday US catches down.
Medium-term (this week): Core PCE (Friday) is the week's second-biggest variable. Oil crash = inflation expectations cooling = Fed easing bias opens up. But the Fed needs actual PCE prints to move. Beige Book (Wed) gives first assessment of oil shock impact on the real economy.
Key risk: No deal + talks collapse. Oil violently rebounds ($105+), VIX back above 25, global risk assets return to wartime pricing. Keep 20% cash reserve for tail risks. "Buy the rumor, sell the fact" — if a deal signs, avoid chasing Tuesday's US open.
