Iran’s economy is drawing renewed attention as the United States prepares to announce a new round of sanctions aimed not only at Tehran but also at countries and companies that continue doing business with Iran.
U.S. Treasury Secretary Scott Bessent is scheduled to detail the measures at a news conference Monday, August 24, after President Donald Trump described the campaign as an “economic D-Day” and threatened what officials called an unprecedented effort to isolate Iran financially. The exact scope of the sanctions had not been publicly disclosed before the announcement.

Iranian officials have responded with threats of retaliation, including warnings that Tehran could halt oil shipments through the Strait of Hormuz if neighboring countries join the U.S. pressure campaign. That has pushed Iran’s economy into the center of a broader dispute involving energy markets, shipping and the risk of further regional escalation.
What is happening now
The immediate issue is a planned expansion of U.S. economic pressure. Iran has already faced extensive American sanctions for decades. The new measures are expected to focus heavily on so-called secondary sanctions: penalties on foreign banks, companies or governments that help Iran trade, move money or sell oil.
Primary sanctions generally restrict U.S. citizens and businesses from dealing with a targeted country. Secondary sanctions go further by threatening non-U.S. entities with losing access to the American financial system if they continue certain transactions with the sanctioned country.
U.S. officials have not yet released the complete package, so it remains uncertain which countries, banks, shipping companies or energy businesses will be targeted. China is a particularly important question because it has remained a major buyer of Iranian oil and a significant economic partner for Tehran. Analysts have warned that aggressive action against Chinese firms could create a new confrontation between Washington and Beijing.

Iranian officials, meanwhile, have said that any neighboring country joining the American sanctions effort could be treated as an enemy. The country’s security leadership has also threatened to prevent oil from moving through the Strait of Hormuz if regional governments cooperate with Washington.
Why the Strait of Hormuz matters
The Strait of Hormuz is a narrow waterway between Iran and Oman that connects the Persian Gulf with the Gulf of Oman and the wider Indian Ocean. It is one of the world’s most important energy corridors.
Before the current conflict, roughly one-fifth of global oil and gas trade moved through the strait, according to reporting cited by The Associated Press. Any sustained disruption could reduce available supplies, raise shipping and insurance costs, and put upward pressure on energy prices.

Traffic has already fallen sharply during the conflict. CNN reported that shipping levels were running at about 20% of the prewar average, although some Iraqi oil tankers were later allowed to pass after requests from Baghdad. Other reporting has indicated that Iran has permitted selected shipments involving countries such as Iraq, Pakistan and China, suggesting that access has not been uniformly blocked. ([transcripts.cnn.com](https://transcripts.cnn.com/show/cnr/date/2026-08-23/segment/21?utm_source=openai))
That distinction matters. A threat to close the strait is not the same as a confirmed full closure. The economic consequences would depend on how long any restrictions lasted, whether tankers could pass under military escort, how much oil could be rerouted, and whether other governments joined the confrontation.
How vulnerable is Iran’s economy?
Iran’s economy was under substantial pressure even before the latest sanctions proposals. International restrictions have limited its access to global banking, reduced investment and complicated the sale of its most important export: oil.
Oil revenue is central to Iran’s government finances and foreign-exchange supply. When exports are restricted, the government has fewer dollars and other hard currencies available to pay for imports, stabilize the currency and support public spending. Restrictions can also make it more difficult for Iranian companies to obtain equipment, insurance and financing.
Iran has nevertheless developed ways to operate under sanctions. It has relied on informal financial networks, intermediary companies, discounted oil sales and trade relationships with countries willing to maintain commercial ties. That experience is one reason analysts caution that even severe new measures may not produce an immediate political result.
The Associated Press reported that Iranian families are already struggling with the cost of basic goods as sanctions, war-related damage and restrictions on oil exports compound existing economic problems. The report also noted uncertainty over whether intensified pressure would lead quickly to military or political concessions from Iran.

What sanctions could mean for ordinary Iranians
Sanctions are formally directed at governments, banks, companies and sectors, but their effects often reach households.
- Prices: A weaker currency can make imported food, medicine, machinery and consumer goods more expensive.
- Jobs and wages: Businesses that lose access to financing or export markets may reduce production, delay wages or cut workers.
- Medicine and supplies: Humanitarian exemptions may exist on paper, but banking restrictions and fear of enforcement can make suppliers reluctant to transact.
- Energy access: Iran is a major oil producer, but sanctions and infrastructure damage can still contribute to fuel shortages or uneven distribution.
- Public services: Reduced government revenue can constrain spending on health care, subsidies, transportation and other services.
Sanctions do not affect every person equally. People with access to foreign currency, private networks or politically connected businesses may be better positioned than wage earners, rural households and small businesses that depend on formal markets.
Why the policy is controversial
The administration’s stated goal is to use economic pressure to force Iran to accept U.S. demands, including limits on its nuclear program and greater access through the Strait of Hormuz. Officials have also said the campaign is intended to reduce Iran’s ability to finance military operations and regional partners. ([criticalthreats.org](https://www.criticalthreats.org/analysis/iran-update-special-report-august-20-2026?utm_source=openai))
Supporters of the approach argue that sanctions can impose costs without requiring a larger military campaign. They also contend that targeting Iran’s trading partners could close loopholes that have allowed Tehran to continue selling oil and accessing foreign currency.
Critics counter that Iran has lived under sanctions since the 1979 Islamic Revolution and has repeatedly adapted. They argue that broad economic pressure can hurt civilians more quickly than it changes government behavior, while also encouraging Iran to deepen ties with China, Russia and other non-Western partners.
There is also a risk of unintended economic consequences. If sanctions sharply reduce oil shipments or trigger a confrontation around Hormuz, higher energy prices could affect consumers well beyond the Middle East. The size and duration of that effect would depend on the policy’s details and on how Iran and other governments respond.
What remains uncertain
Several key facts were still unresolved ahead of Monday’s Treasury announcement:
- Which foreign governments or companies will face penalties?
- Will the United States target Chinese banks or energy firms involved in Iranian trade?
- Will sanctions include waivers, wind-down periods or humanitarian exceptions?
- How will Washington enforce the measures against oil shipments using intermediaries?
- Will Iran restrict commercial traffic through Hormuz, and if so, for how long?
- Will other countries cooperate with the U.S. campaign or attempt to bypass it?
Those details will determine whether the new policy is largely symbolic or represents a major change in Iran’s ability to earn and move money.
What happens next
The next immediate step is the U.S. Treasury briefing scheduled for Monday, August 24. Markets, shipping companies and foreign governments are likely to focus on whether the measures target Iran alone or extend to its most important trading partners.
Iran’s response will also be closely watched. A formal warning is not proof that Tehran has decided to close Hormuz, but any action affecting tanker traffic could quickly become an international economic issue. Governments in the Gulf will face pressure to balance their economic ties with Iran, their security relationships with the United States and the risk of retaliation.
For Iranian households, the most significant effects may be less dramatic but more persistent: higher prices, weaker purchasing power, shortages of imported goods and greater uncertainty for businesses. Whether the pressure changes Iran’s policy remains unproven. What is confirmed is that economic measures have become a central front in the U.S.-Iran conflict, with consequences that could extend from Iranian markets to global energy supplies.
