US Dollar Slips as US-Iran-Oman Deal to Reopen Strait of Hormuz Nears

The Hormuz Interim Agreement: Terms, Status, and Parties

As of August 5–6, 2026, the United States, Iran, and Oman are in the final stages of an interim agreement to reopen the Strait of Hormuz. Washington aimed for a formal announcement on Wednesday, August 5, though President Trump said it could come Wednesday or Thursday .

Key terms of the emerging deal:

• 60-day temporary arrangement to restore shipping through the Strait of Hormuz, with an option for extension .
• Ships would enter the Persian Gulf through an Iranian-controlled northern lane and exit via an Omani-controlled southern lane, with both nations managing navigation, security, and service fees in their respective sectors .
• The agreement would restore the ceasefire between the US and Iran that collapsed last month, and help de-escalate the broader Middle East conflict .
• The deal is explicitly not a permanent settlement; it is designed to buy time for further negotiations on Iran's nuclear program and other issues .

Parties involved: The US and Iran are the principals, with Oman acting as the key mediator. Qatar has also been involved in parallel mediation efforts .

Caveats and Risks

The deal faces real headwinds. Iranian state media, citing an informed source, said the agreement "will be delayed as long as the United States continues to threaten Iran" . Iran's foreign minister has insisted the waterway will "never return to its pre-war status," signaling that reopening terms may not be unconditional . A 14-point Memorandum of Understanding between Washington and Tehran collapsed as recently as last month, underscoring the fragility of the negotiating track .

Broader Market Implications

The Hormuz reopening hopes were the single biggest macro driver of the week, with effects cascading across asset classes:

• Oil prices collapsed: WTI crude fell 6.21% to $75.35 per barrel and Brent dropped 5.74% to $78.96 on the day of Bessent's comments, extending a multi-day slide . Danske Bank strategists attributed the rout directly to the Hormuz deal reports, noting Bessent's remarks "pushed Brent crude below $80/barrel" .
• Equities surged to records: US and European equities hit all-time highs, and Asian markets rebounded sharply, led by technology shares and optimism from lower oil input costs .
• Risk flows dominated: The dollar weakened broadly as capital rotated out of safe havens into riskier assets .
• Volatility remained elevated: Despite equity records, volatility measures firmed as hedging built ahead of data-heavy week, reflecting uncertainty over whether the deal would hold .

Bottom line: The Hormuz reopening hopes have lifted risk assets and crushed oil prices while exerting fresh downward pressure on the dollar. But the deal's temporary 60-day structure and Iran's public caveats mean the market is pricing a fragile optimism — not a durable resolution.
