Potential US-Iran rapprochement would reshape Middle Eastern power balance, reducing Iranian isolation and potentially constraining US unilateral leverage. Success would strengthen Trump's negotiating credibility but could concern regional allies (Israel, Saudi Arabia, UAE) dependent on US containment strategy.
Similar to 2015 JCPOA negotiations, which initially boosted markets on de-escalation hopes but faced implementation challenges and eventual US withdrawal under Trump's first term, creating skepticism about durability.

Lower oil prices could reduce energy costs and inflation pressures for households, but geopolitical uncertainty and potential Fed rate hikes may increase borrowing costs and reduce purchasing power.
Federal Reserve may reconsider interest rate trajectory depending on inflation persistence; potential sanctions relief could affect trade policy; defense spending priorities may shift if Middle East tensions ease.
