Oil prices remain well below recent peaks even as the Strait of Hormuz closure drags on without resolution. Brent crude traded near $88 a barrel Tuesday, up from $83 at last week's close, but still 13 percent below the $100 level hit last month and 20 percent below May's $110 peak.

The $5 rebound follows a 7 percent decline last week after Washington signaled potential talks with Tehran to reopen the chokepoint. Those negotiations stalled over the weekend. Iran now demands U.S. compliance with unspecified conditions before reopening. President Trump told Axios on Sunday the administration would pursue economic pressure rather than immediate military strikes.

Markets initially took comfort from two factors: ongoing Iran-Oman talks about a temporary shipping corridor and receding near-term military escalation risk. Modupe Adegbembo, economist at Jefferies, told CNBC on Monday that traders believe some form of agreement remains achievable. But she warned the optimism has an expiration date. "If the situation persists without resolution by the end of this week or into next week, oil prices would likely not continue to move in such a benign manner," she said.

Kieran Tompkins, senior climate and commodities economist at Capital Economics, quantified the market's current calculation. The $88 price reflects investors balancing two scenarios: quick reopening versus prolonged closure. If the deadlock extends, traders will assign higher probability to extended disruption and push front-month futures higher.

Tompkins identified a structural inflection point: when OECD inventory drawdowns exhaust the market's absorption capacity. At that stage, demand destruction via price spike becomes necessary to match constrained supply. He estimates this tipping point arrives around early Q4 if the strait remains closed and inventories deplete rapidly.

Historical precedent suggests such a scenario could drive prices to $120 to $140 per barrel—a 35 percent to 60 percent move from current levels. Current pricing suggests the market is not fully pricing this tail risk. The 20 percent discount from May's highs and 12 percent discount from last month's surge indicate continued confidence in near-term resolution despite deteriorating diplomatic signals.
