Iran has formally denied conducting negotiations with the United States, contradicting President Trump's assertion of productive talks, and triggering a sharp rebound in crude prices as markets reassess supply security.

Brent crude jumped 3.99% to $103.93/bbl while WTI gained 4.56% to $92.14/bbl as traders recognized the collapse of brief hopes for imminent Hormuz reopening. The denial underscores the fragility of negotiated settlements: even rhetoric shifts can swing oil markets 10+ percentage points intraday.

Markets had priced in a 5-day negotiation window as a confidence signal; the denial flipped sentiment immediately. Analysts warn that absent credible compromise frameworks, crude will remain vulnerable to geopolitical shock with each diplomatic statement.
