U.S. sanctions and blockade deepen Iran strain

U.S. Treasury chief Scott Bessent has said he will present details of a new sanctions package against Iran at a press conference on Monday. The measures have been described in reporting as the "toughest sanctions in history," signaling an escalation in economic pressure on Tehran. The announcement comes on top of existing restrictions and aims to further constrain Iran’s access to global finance and trade.

While specific instruments of the package have not yet been disclosed, the timing aligns with broader U.S. efforts to intensify pressure following renewed military enforcement around Iran’s energy exports. The pending details have added uncertainty for regional markets and for countries that still purchase Iranian crude.

The United States re-imposed a naval blockade on Iran in mid-July, reported as July 13, targeting the country’s ability to ship crude oil. Reporting indicates that the blockade has reduced Tehran’s capacity to export crude and led to fewer offers of Iranian oil to Chinese buyers, a key outlet for Iranian barrels.

The blockade directly affects Iran’s main source of hard currency, tightening the link between maritime security operations and the broader sanctions regime. Reduced export flexibility constrains Iran’s revenue, amplifying the impact of existing and forthcoming financial penalties.

Interviews and official comments from within Iran describe a sharp deterioration in living conditions as sanctions and the blockade take hold. Rice prices are reported to be about 60% higher and beef about 150% higher than before the war, putting basic protein and staple foods out of reach for many households.

One consumer cited spending 89 million rials, about $65, on a small grocery basket, underscoring the erosion of purchasing power. The International Monetary Fund is cited as expecting inflation to rise nearly 70% by year-end and forecasting that Iran’s economy will shrink by more than 5%, pointing to a severe macroeconomic shock.

Labor market data also show significant stress. A Labor Ministry official said that more than one million jobs had been lost by late May, indicating that sanctions and disrupted trade flows are spilling quickly into employment and household income.

Iran’s Foreign Ministry has condemned the intensified U.S. sanctions as "economic terrorism" and asserted that such measures will not weaken the determination of the Iranian population. Political leaders, including the parliament speaker, have called for planning to manage the sanctions and associated economic pressures.

Military officials have coupled this political stance with explicit warnings. Major General Ali Abdollahi stated that Iran’s armed forces would respond to any new U.S. threats with "crushing, punishing and devastating responses" across land, sea, air, air defence and cyberspace. The rhetoric highlights the risk that economic confrontation could intersect with security tensions in and around the Gulf.
