US-Iran Negotiations Hit Impasse as Trump Rejects Hormuz Proposal, Oil Volatility Persists

The fragile US-Iran ceasefire is showing cracks as President Donald Trump on Friday rejected Tehran's latest diplomatic proposal, declaring he is "not satisfied" with Iran's terms while maintaining a naval blockade that has choked off 20% of global oil and liquefied natural gas supplies for nearly two months.

Iran delivered a new proposal to the United States via Pakistani mediators on Friday, according to Iran's state-run Islamic Republic News Agency (IRNA). However, Trump told reporters the proposal contained demands "I cannot agree with," adding that phone negotiations are continuing but "they're not getting there."

Strait of Hormuz Remains Closed as Diplomatic Deadlock Deepens

The Strait of Hormuz—a critical maritime chokepoint through which approximately one-fifth of the world's oil flowed before the crisis began—lies at the heart of the current impasse. Both nations have signaled they are waiting for the other to move first before easing restrictions on maritime traffic.

"Good luck blockading a country with those borders," Iran's Parliament Speaker Mohammad Bagher Ghalibaf posted on X, referring to Iran's extensive land boundaries. Iranian officials insist the US blockade must be lifted before substantive talks can resume and Hormuz can reopen.

Trump's position remains firm: the blockade will continue as leverage to force Tehran back to the negotiating table. "The blockade of Iranian ports is depriving the Islamic Republic of much-needed oil revenue," Trump said Thursday, claiming the pressure would compel Iran to accept US terms.

Iran's new supreme leader, Mojtaba Khamenei, cast further doubt on prospects for a deal Thursday, vowing in a rare statement not to surrender the country's nuclear or missile technologies while signaling Tehran would maintain control of Hormuz.

Oil Markets Whipsaw Between $110-116 as Traders Price Geopolitical Risk

Brent crude traded around $111 per barrel on Friday, down 3% from the prior session but still holding above $110 for the second consecutive week. The benchmark briefly touched $116.10 on Thursday before retreating on speculation that diplomatic talks might yield progress.

Oil prices have surged more than 73% year-over-year, with the supply shock from the Hormuz closure reshaping global energy markets. Analysts at Angle360 forecast Brent will trade between $115-135 per barrel in May, while WTI crude is projected to range from $105-125, depending on whether the Strait reopens.

The prolonged closure has pushed European currencies and commodity-linked pairs into volatile territory. EUR/USD has shown increased correlation to crude prices as the eurozone grapples with stagflation risks tied to elevated energy costs. The Norwegian krone (NOK) and Canadian dollar (CAD)—both oil exporters—have rallied alongside Brent, while import-dependent currencies like the Japanese yen (JPY) face pressure from surging energy import bills.

Forex Implications: Safe Havens Rally, Dollar Mixed

The geopolitical uncertainty is driving forex traders into safe-haven assets. Gold (XAU/USD) continues to trade near multi-year highs above $5,000 per ounce, while the Swiss franc (CHF) has strengthened against most major currencies.

The US dollar ($DXY) remains caught in a tug-of-war: geopolitical risk supports the greenback as a safe haven, but weaker-than-expected US economic data—including Thursday's ISM Manufacturing print of 52.7 versus 53.0 expected—has tempered bullish momentum.

Emerging market currencies tied to oil imports, including the Turkish lira (TRY) and Indian rupee (INR), face significant headwinds. India's banking sector data released May 1 showed deposit growth steady at 12.2%, but analysts warn sustained high oil prices could erode purchasing power and pressure the rupee lower.

War Powers Act Deadline Looms, Congress Demands Answers

The diplomatic stalemate coincides with a critical milestone: the conflict is approaching the 60-day threshold under the US War Powers Act, which requires Congressional authorization for continued military action beyond that window.

US Defense Secretary Pete Hegseth faced intense questioning from lawmakers Thursday, with Democrats arguing the Pentagon has underestimated the war's cost. One senator suggested the $25 billion figure provided by the Defense Department is "probably less than half, maybe less than a quarter, of the total cost."

The administration maintains that a ceasefire reached three weeks ago has "terminated" hostilities, though critics note the naval blockade and ongoing reconnaissance operations constitute continued engagement.

US Pitches "Maritime Freedom Construct" to Allies

In a diplomatic push outlined in a State Department cable Tuesday, the US is urging allies to join a new international coalition called the "Maritime Freedom Construct" to secure passage through the Strait of Hormuz.

The proposed coalition would share intelligence, coordinate diplomacy, and help enforce sanctions. However, key allies including France and the United Kingdom have signaled they would only participate after a sustainable ceasefire is in place.

New Zealand, which received the US proposal this week, echoed that position, stating it would support a coalition only if hostilities genuinely cease.

What Traders Should Watch

Forex and commodity traders should monitor several key developments over the next 7-10 days:

• War Powers Act deadline: Congressional action (or inaction) could signal whether the conflict escalates or enters a new phase of negotiations.
• Oil price levels: A sustained break above $120 per barrel would likely accelerate EUR/USD downside and boost CAD, NOK. Conversely, a breakthrough in talks could trigger a sharp oil selloff.
• Iranian currency weakness: Signs of economic strain in Iran have emerged, with the rial hitting fresh lows. A collapse in Iran's currency could force Tehran back to the table.
• US economic data: Next Friday's Non-Farm Payrolls (NFP) report will be critical. A weak jobs print could undermine dollar strength even as geopolitical risk supports safe-haven flows.
• Central bank responses: Watch for commentary from the Federal Reserve, European Central Bank, and Bank of England on how prolonged energy shocks are influencing cpi" title="Understanding inflation and CPI in forex">inflation and rate path expectations.

Technical Levels to Watch

Brent Crude: Support at $108 (prior consolidation zone), resistance at $116-120 (April highs). A breakout above $120 would target $125-130.

EUR/USD: Watch the 1.0500 support level. A breakdown below 1.0450 could accelerate losses toward 1.0350. For further insights, see our EUR/USD analysis.

XAU/USD (Gold): Holding above $5,000 psychological support. A close above $5,150 would open the door to new all-time highs. Learn more about trading gold during geopolitical crises in our risk management guide.

USD/CAD: Resistance at 1.3400 (downtrend line). If oil rallies, watch for a break below 1.3200 toward 1.3000. See our USD/CAD forecast for detailed analysis.

Bottom Line

The US-Iran negotiation deadlock is entering a critical phase, with the War Powers Act deadline, persistent Hormuz closure, and volatile oil prices creating a high-risk environment for forex traders. While Trump maintains his hardline blockade strategy, the economic cost—both in defense spending and energy market disruption—is mounting.

Until concrete signs of a breakthrough emerge, expect heightened volatility in oil-linked currencies, continued safe-haven demand, and elevated implied volatility across major pairs. Traders should use tight stop losses and consider reduced position sizing given the binary nature of geopolitical risk.
