The United States has significantly stepped up pressure on Iran, combining tougher economic sanctions with increased military activity around key regional shipping routes, while calling on China and other countries to help isolate Tehran.
The latest developments mark another major escalation in the long-running US-Iran confrontation, with Washington warning of severe economic consequences and Tehran rejecting the campaign as ineffective. At the same time, tensions around the Strait of Hormuz continue to create uncertainty for global shipping and energy markets.
US Treasury Secretary Scott Bessent has pledged what he described as the toughest sanctions in US history against Iran, arguing that economic pressure remains central to Washington’s strategy. Vice President JD Vance similarly described economic pressure as the administration’s most effective instrument for pushing Tehran toward a deal.
Iran, however, has condemned Washington’s approach and dismissed the threatened economic campaign as a form of economic warfare.
China rejects Washington’s call for greater pressure
China has refused to endorse the US strategy, saying sanctions and economic pressure will not resolve the conflict.
Chinese Foreign Ministry spokesperson Lin Jian said Friday that the parties involved should pursue political and diplomatic solutions instead of relying on unilateral economic measures.
Beijing also reiterated its opposition to sanctions that it considers inconsistent with international law or not authorised by the United Nations Security Council.
The response came after Bessent urged China to cooperate with Washington’s campaign. Asked whether the United States would pressure Beijing to join the effort, Bessent said some discussions were better handled privately but nevertheless called on China to support the US approach.
China’s position could complicate Washington’s attempt to build a wider international economic front against Tehran. China remains an important player in global energy markets and has significant economic ties across the Middle East.
Washington expands sanctions against Hezbollah
The US pressure campaign has also widened beyond Iran itself.
Washington announced additional sanctions targeting an alleged financial network connected to Hezbollah, the Lebanese armed group that the United States has long designated as a terrorist organisation.
The Treasury Department said the network allegedly moved large amounts of cash between Lebanon, Turkey, the UAE and Iran through couriers travelling on commercial flights.
According to US officials, the network provided Hezbollah with access to foreign currency outside the formal financial system and helped the group evade sanctions.
The United States also updated its description of Hezbollah to underline what it says are extensive operational, financial and logistical links between the group and Iran’s Islamic Revolutionary Guard Corps’ Quds Force.
The latest measures come as Washington facilitates direct negotiations between Israel and Lebanon. Hezbollah has rejected those talks.
US military activity intensifies around Iran
Economic pressure is being accompanied by increased military activity in and around the region.
US Central Command said American forces had redirected 67 commercial vessels, disabled three and boarded two others as part of efforts to enforce a blockade against Iran.
The announcement illustrates the increasingly complicated security environment facing commercial shipping in the region. The Strait of Hormuz, which connects the Persian Gulf with the Gulf of Oman, remains one of the world’s most important energy corridors.
Any sustained disruption in the waterway could have consequences well beyond the Middle East, potentially affecting crude oil supplies, shipping costs, insurance premiums and consumer prices in major economies.
US forces have also continued operating military aircraft and naval assets in the Arabian Sea as Washington maintains pressure on Iran.
Strait of Hormuz traffic falls sharply
Shipping activity through the Strait of Hormuz has declined amid the worsening security environment.
Preliminary data from ship-tracking company Kpler showed that seven commodity vessels passed through the strategic waterway on Thursday, compared with 14 the previous day.
Four of Thursday’s vessels were entering the Gulf, while three were travelling out.
Notably, no supertankers or liquefied natural gas carriers were recorded passing through the Strait during the period covered by the data.
A large gas carrier carrying propane and butane was nevertheless reported to have exited the waterway through the Iranian route.
The decline in traffic underscores the caution among shipping operators as companies assess security risks and the potential consequences of further escalation.
Oil prices remain elevated
Energy markets have reacted strongly to the continuing uncertainty.
Brent crude futures were down slightly in early Friday trading at around $93.55 a barrel, while US West Texas Intermediate crude was near $86.50.
Despite the modest daily declines, both benchmarks were on track for another weekly increase. Brent had gained more than 7 per cent over the previous five sessions, while WTI had risen more than 8 per cent.
The market’s focus remains firmly on developments around Iran and the Strait of Hormuz.
A prolonged disruption to shipping could put further upward pressure on crude prices, particularly if major oil producers or tanker operators face additional restrictions.
Higher oil prices could also increase transportation and manufacturing costs globally, adding to inflation concerns for economies that depend heavily on imported energy.
Gold heads for another weekly gain
Gold has also benefited from the uncertain geopolitical environment.
Spot gold was trading at approximately $4,514.23 an ounce in early Asian trading on Friday after reaching its highest level since early June during the previous session.
The precious metal had gained about 3.2 per cent since the beginning of the week and was heading towards its third consecutive weekly increase.
A weaker US dollar and efforts by the US Treasury to contain rising long-term bond yields have also supported gold prices.
Other precious metals were similarly stronger on the week. Silver was around $68.03 an ounce, while platinum rose to approximately $1,846.29 and palladium stood near $1,333.11.
USS Abraham Lincoln begins return journey
The USS Abraham Lincoln has begun its long-awaited journey back to San Diego following an extended deployment in the Middle East.
The aircraft carrier and its roughly 5,000 sailors have spent more than nine months deployed during the Iran conflict. The USS George Washington is taking over its regional role.
The deployment included thousands of combat sorties and more than 200 consecutive days at sea.
The prolonged mission placed considerable pressure on the crew. Reports highlighted fatigue, limited port visits, supply delays and disruptions to basic amenities.
The carrier’s return journey is expected to take several weeks, providing its crew with an opportunity to leave behind one of the US Navy’s longest and most demanding deployments.
Iran faces growing economic pressure
For Washington, economic pressure is intended to weaken Tehran’s ability to sustain its military capabilities and ultimately push Iran toward negotiations.
Vance said the administration’s objective was not simply to impose economic costs but to prevent Iran from rebuilding its nuclear capabilities and encourage the country to reach an agreement.
The strategy, however, remains controversial.
Iran has rejected the US campaign and accused Washington of pursuing economic warfare. Tehran has maintained that external pressure will not force it to surrender its strategic interests.
The standoff therefore remains centred on whether economic sanctions can achieve the political objectives set by Washington or instead deepen the confrontation.
US national debt reaches $40 trillion
The geopolitical developments come as the United States faces another major economic milestone.
US national debt has surpassed $40 trillion, reaching the level only months after crossing $39 trillion in March.
The rapid increase has renewed attention on the cost of government spending, interest payments, defence expenditure and social programmes.
The debt milestone is particularly significant as Washington expands defence-related commitments amid conflicts and security tensions across the Middle East.
Rising interest costs could further complicate the government’s fiscal position, particularly if borrowing costs remain elevated.
Gaza conflict adds to regional tensions
The broader Middle East crisis is also being shaped by developments in Gaza.
Hamas has said it remains committed to a 15-point Gaza peace roadmap and expects mediators and the Board of Peace to continue advancing the proposal.
Senior Hamas official Bassem Naim said the group was prepared to continue discussions aimed at restoring stability and improving conditions for Palestinians.
However, Hamas has accused Israel of failing to meet ceasefire obligations, including restrictions on humanitarian assistance, while continuing military operations.
The issue has further complicated diplomatic efforts across the region, as governments attempt to address the conflicts in Gaza, Lebanon and Iran simultaneously.
US senator condemns Israeli minister’s Gaza remarks
US Senator Elissa Slotkin has also criticised Israeli National Security Minister Itamar Ben-Gvir over comments concerning civilians in Gaza.
Slotkin described the remarks as violent and dehumanising and called for Ben-Gvir to be removed from government.
Her criticism adds to growing political debate in the United States over Israel’s conduct in Gaza and the wider consequences of the regional conflicts.
The dispute comes as Washington simultaneously seeks to advance negotiations in the region while maintaining strong support for Israel.
What the latest developments mean for the region
The latest developments point to a conflict that is increasingly affecting diplomacy, trade, energy and financial markets at the same time.
The US decision to intensify sanctions against Iran and Hezbollah indicates that Washington is relying heavily on economic tools alongside military pressure. China’s rejection of that approach, meanwhile, demonstrates that the United States may face difficulties in securing broad international support.
For Gulf countries, the Strait of Hormuz remains particularly important.
Any prolonged disruption could affect oil exports, shipping schedules, insurance costs and regional trade. Businesses operating across the Gulf are therefore likely to continue monitoring developments closely.
For global markets, the combination of elevated oil prices, stronger demand for gold and uncertainty around maritime trade reflects the economic risks associated with the confrontation.
Diplomatic efforts remain critical
Despite the escalation, diplomacy remains central to any long-term solution.
Washington says its economic campaign is designed to pressure Tehran into negotiations, while China is calling for political and diplomatic engagement rather than sanctions.
The continued uncertainty around the Strait of Hormuz also increases the urgency of preventing further escalation.
Whether the latest sanctions produce a diplomatic breakthrough or lead to additional confrontation remains unclear. For now, Iran, the United States and their regional partners remain locked in a high-stakes standoff with consequences that extend far beyond their borders.
Dubai Herald will continue to monitor developments involving the US-Iran conflict, Strait of Hormuz tensions, sanctions, oil markets and wider Middle East diplomacy.
