Eyes on the Strait of Hormuz: Oil Prices Tumble

Summary

Chris Harmse is the consulting economist of Sequoia Capital Management and a senior lecturer at Stadio Higher Education. Image: Supplied Financial markets across the globe await the possibility of the opening of the Strait of Hormuz. CNBC reported that “As of May 8, 2026, the Strait of Hormuz remains effectively closed to most commercial shipping due to an ongoing blockade following the outbreak of conflict between the US/Israel and Iran in late February 2026. While negotiations are ongoing, Iran has stated it will not reopen the waterway without its permission, suggesting a full reopening may not occur until the second half of 2026. This statement from Iran stopped a sharp decrease in the oil price on Friday. Markets were optimistic from last Tuesday to Thursday that the strait may be opened within the coming week. In reaction, the Brent oil price fell sharply from $113 last Monday to as low as $97 on intra-day trade on Thursday (7 May). This optimism saw the prices for precious metals recover quickly, and the Rand exchange rate appreciated strongly. The gold price increased last week by $184 to close Friday at $4,707, whilst the price of platinum shot up by $82 per ounce to $2,052 on Friday. The Rand exchange rate improved by 40 US cents from $16,80 last Monday to close at $16,40 last Friday. At one stage last Wednesday, the Rand traded as low as R16,26/$. This is only 30 cents weaker than the R15,96 the day before the Iran attack by the U.S. and Israel. The JSE share indices followed the same pattern, led by the JSE metal and mining index. The index improved by 6,65% last week. This strong increase pushed the Top 40 index higher by 4,8% last Thursday but given the uncertainty around the opening of the Strait of Hormuz, the index ended the week 2,7% higher. The ALSI followed the same pattern, advancing quickly by 3,5% over the week until Thursday but lost 1,06% on Friday. Fuel Prices Given the sharp increase in the Brent oil price and the sharp depreciation in the Rand/$ exchange rate, the price for petrol was increased by R3,27 per litre and that for diesel by R5,26 per litre last Wednesday. The Minister of Finance, Mr Enoch Godongwana, renewed the lower fuel levy of R3,00 per litre for petrol and increased the lower fuel levy for diesel to R3,93 per litre. Both the price of petrol at R26,63 and diesel at R31,17 reached record prices last Wednesday. Many analysts feared that these prices may even rise again at the beginning of June, especially if the lower fuel levy expires. This will have a severe effect on prices throughout the economy, given the massive downstream effects on food and other input costs in the economy. The MPC of the Reserve Bank has already forecasted that the inflation rate for South Africa is expected to quickly increase from 3,1% in March to 5,0% by the second part of the year. Under such a scenario, a 50-basis point increase in interest rates was envisaged. The strong recovery in the oil price last Thursday and Friday, to levels just above $100 per barrel, and the appreciation of the Rand by 40 cents/$ had changed these fears. By last Friday, the price of diesel had already recovered by R2,48 cents per litre, whilst the price for petrol was still under recovered by 83 cents per litre. It is now expected that this more favourable position may improve over the next three weeks and that motorists may experience lower prices in June, especially for diesel. This coming week, financial markets will still be mostly affected by the events of the ongoing conflict in the Middle East. It was announced on Friday that the US economy added 115,000 jobs in April 2026, according to the latest report from the Bureau of Labor Statistics (BLS). This figure significantly exceeded the market forecast of 62,000. Together with the higher fuel prices in the US and the inflation rate for April that will be announced this Tuesday and is expected to remain at 2,3%, it is now a given that the Federal Reserve will not lower interest rates. The Federal Open Market Committee (FOMC) will meet next week. The US will also release its retail sales for April this coming Thursday. Elsewhere, the UK will announce its economic growth rate (GDP) (preliminary estimation) for Q1 2025 on Thursday. Domestically, STATSSA will release the latest mining production figures for March on Thursday.

Perspectives

Iranian Official

In response to the unprovoked aggression launched by the US and Israel against Iran in late February 2026, the Islamic Republic has exercised its sovereign authority to maintain the closure of the Strait of Hormuz, rejecting any external dictates on its territorial waters. This act of resistance affirms Iran's right to control access through the waterway and conditions any reopening on its own terms, potentially not before the second half of 2026. By upholding this stance, Iran has thwarted market speculation and foreign pressure aimed at undermining its defensive measures.

Israeli

Israel's defensive campaign against Iran's nuclear and proxy network, launched in February 2026, remains essential to counter the regime's existential threat of strangling global energy routes. By maintaining its illegal blockade of the Strait of Hormuz, Tehran continues to weaponize shipping lanes, driving oil prices and exposing the direct costs of unchecked Iranian aggression.

Neutral

Financial markets have reacted to reports of the Strait of Hormuz remaining closed to most commercial shipping as of May 8, 2026, following the outbreak of conflict involving Iran, the US, and Israel in late February 2026. According to CNBC, Iran has indicated that reopening would require its approval and may not occur until the second half of 2026. Oil prices fell from $113 to as low as $97 per barrel midweek before stabilizing, while gold rose $184 to $4,707 per ounce, platinum increased $82 to $2,052 per ounce, and the rand strengthened by 40 US cents to R16.40 against the dollar.

Western

Western and Israeli forces conducted precision strikes against Iranian military targets in late February 2026 to neutralize Tehran's threats and proxy networks, resulting in the effective closure of the Strait of Hormuz to most commercial traffic. Negotiations continue toward a controlled reopening aligned with coalition security objectives, though Iranian obstruction has delayed full transit until at least the second half of 2026. Temporary market optimism over a potential early reopening drove Brent crude down from $113 to $97, while gold, platinum, and the Rand saw corresponding gains.

Pro-Peace

The US/Israel-Iran conflict that erupted in late February 2026 has kept the Strait of Hormuz blockaded, strangling commercial shipping and inflicting mounting civilian hardship through disrupted food, medicine, and fuel supplies across the region. Iran’s insistence on controlled reopening only after negotiations highlights how military escalation continues to exact a human toll, with fleeting market optimism over a possible May reopening proving illusory. Diplomatic channels must be urgently pursued to end the blockade and avert further casualties rather than prolonging a standoff that benefits no one but arms suppliers.

Global South

In the aftermath of the US and Israeli February 2026 strikes on Iran, Tehran’s sovereign decision to maintain the Strait of Hormuz blockade has laid bare neo-colonial efforts to dominate energy routes vital to Global South economies. This assertion of control halted a steep Brent crude decline from $113 to $97 per barrel, lifted gold and platinum prices, and allowed the Rand to recover modestly from R16.80 to R16.40, revealing how Western-initiated conflicts inflict disproportionate costs on non-aligned states. The episode further exposes the impotence of international institutions in restraining such interventions.

DUBAI, United Arab Emirates (AP) — Iran attacked a tanker in the Strait of Hormuz early Tuesday, forcing its crew to abandon the ship, while the United States conducted yet another round of airstrikes targeting the Islamic Republic as they struggle over control of the key waterway.

The 10 consecutive nights of U.S. airstrikes haven’t compelled Tehran to loosen its grip on the strait, through which about a fifth of all crude oil and natural gas traded once passed in peacetime. Even as the U.S. and Iran inch closer to all-out war again, Iran’s interior minister traveled to Pakistan, a key mediator in the conflict, for talks.

However, it remains unclear just what new deal could be reached to end the fighting. The interim deal signed last month that was meant to end the fighting has crumbled. Shipping through the Strait of Hormuz has largely stalled. And as fighting intensifies, both sides have targeted civilian infrastructure relied on by millions of people.

“Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world,” the U.S. State Department said in a new warning to Americans. The escalation has pushed oil prices higher in recent weeks.

Benchmark Brent crude traded Tuesday above $88 a barrel and regular gasoline in the U.S. climbed to an average of $4 a gallon, keeping pressure on Americans’ wallets ahead of midterm elections this fall. Meanwhile, the U.S. military identified two soldiers who were killed in Jordan in attacks that left a third person missing.

Separately, the military confirmed another death in Iraq on Saturday during the “controlled detonation” of a downed Iranian drone. President Donald Trump took to social media on Monday to warn that “Every time Iran kills an American Soldier they will pay for that killing many times over!

” Trump was planning to attend a ceremony on Tuesday evening at Dover Air Force Base, where at least one service member’s remains were due to arrive. US strikes come as ships attacked The U.S. military’s Central Command said Tuesday it targeted “Iranian military command centers, maritime capabilities, missile and drone launch sites and air defense systems.

” It released more footage of bombings that targeted sites in Iran. “American forces remain postured and prepared to hold Iran accountable for unwarranted aggression toward civilian mariners seeking to freely and openly transit the strait,” the command said.

Iranian state media reported that explosions were heard in Fars, Hormozgan, Ilam, Kerman and Sistan and Baluchistan provinces. However, traffic through the strait has slowed to a crawl during the latest violence. Lloyd's List Intelligence said only three ships transited the strait on Sunday.

The British military’s United Kingdom Maritime Trade Operations center said a tanker came under attack early Tuesday in the strait off Oman, forcing the crew to abandon the vessel. Iran’s paramilitary Revolutionary Guard claimed the attack, as well as two other attacks on ships Monday in the waterway.

The route around Oman has been the one the U.S. military has encouraged ships to travel to avoid Iran’s control. The UKMTO separately reported Tuesday that another previously unknown attack on a ship took place early the previous day. Tehran also hit U.

S.-allied countries throughout the Middle East. Jordan military's said Tuesday that Iran targeted it with five drones and three missiles, all of which were shot down. Bahrain sounded its missile alert sirens Tuesday afternoon as another Iranian barrage targeted the island kingdom, which is home to the U.

S. Navy's 5th Fleet. Nearly 100 US injuries since early July The Pentagon’s chief spokesperson said nearly 100 U.S. service members have been injured since the U.S. restarted strikes on July 7, and 96% of them have returned to duty.

“The vast majority of injuries experienced were minor concussions,” Sean Parnell posted Monday on X in response to a New York Times report that the Pentagon has withheld information about troop injuries from Iranian strikes. He denied that the Pentagon was hiding data about injuries.

However, the Defense Casualty Analysis System, the military’s clearinghouse for reporting deaths and injuries in conflict, has not been updated as of Monday night with the latest attacks. Yemen rebels threaten attacks on other Mideast waterway Yemen’s Houthi rebels announced a maritime embargo against Saudi Arabia on Monday.

The Houthis, who are backed by Iran, said they would block shipping between the Red Sea and the Gulf of Aden by targeting the Bab el-Mandeb, a maritime chokepoint like the Strait of Hormuz, in response to an attack on Sanaa International Airport last week that they blamed on Saudi Arabia.

With the Strait of Hormuz blocked, Saudi Arabia has been relying on a pipeline to the Red Sea to get millions of barrels of oil out to market. The Houthis earlier demonstrated their ability to disrupt shipping there when they targeted ships for months over the Israel-Hamas war in Gaza, with over 100 vessels attacked.

Saudi Arabia’s military said it would keep the waterway open. “All Houthi threats against transiting vessels will be dealt with swiftly and firmly, as such threats are a blatant violation of international law and fall under acts of maritime piracy,” said Maj.

Gen, Turki al-Malki, a Saudi military spokesman. A glimmer of hope for diplomacy Pakistan has intensified diplomatic efforts in recent days to resuscitate the interim deal. Iranian Interior Minister Eskandar Momeni arrived in Islamabad on Monday for two days of talks with Prime Minister Shehbaz Sharif and others.

On Sunday, U.S. Secretary of State Marco Rubio told reporters that the U.S. is still open to negotiating with Iran but that “it has to be real.” “If the door opens to diplomacy — if the guys that want to do something productive for Iran win and take control of that system, or take control of the negotiations — that’ll be a very positive development,” Rubio said.

“That’s not where we are tonight, unfortunately.” Iranian authorities on Sunday said at least 50 people have been killed and 517 wounded in the latest rounds of U.S. strikes. Since the war began on Feb. 28, 17 U.S. service members have been killed.

US Secretary of War Pete Hegseth posted social media images showing damage to a maritime control tower at Iran’s Chabahar port following reported US military strikes, accompanied by the caption “Iran does not control the Strait of Hormuz.” India’s Ministry of External Affairs stated that the Shahid Beheshti terminal operated by India at the port sustained no damage.

The ministry reiterated its position that civilian infrastructure should not be targeted during conflicts.

Yemen's Iran-aligned Houthis announced Monday they would impose a maritime blockade on Saudi Arabia, further throttling a global energy market already greatly restricted by Iran's closure of the Strait of Hormuz. This is why it matters and what it means for the Iran war and the global energy crisis.

It is not clear how the Houthis would carry out a maritime blockade of Saudi Arabia, its northern neighbor along the Red Sea coast, or whether it would include a return to attacks on shipping. Yemen sits on the Bab el-Mandeb strait – the southern gateway to the Red Sea – and closing that would open up a new front in the energy crisis and Iran's overarching conflict with the U.

S. With the Strait of Hormuz already disrupted, the Red Sea has become a critical alternative outlet for Gulf oil and other products. A serious disruption would mean both of the Middle East's major oil export routes are shut simultaneously. Iran's partial blockade of the Strait of Hormuz after Israel and the U.

S. attacked it on Feb. 28 disrupted most oil and other exports from the Gulf, raising prices and delivering a global energy shock. Saudi Arabia responded by diverting more than 70% of its normal daily crude exports to the Red Sea port of Yanbu. Ships from Yanbu bound for Europe go north through the Suez Canal.

Those heading to Asia go south through Bab el-Mandeb. Shipments from Yanbu averaged 4 million barrels per day in recent weeks according to data from Kpler and Signal Ocean, up from around 973,000 bpd a year earlier. Total petroleum volumes transiting Bab el-Mandeb amounted to 7.

4 million bpd in June, or about 7% of global oil output, according to Kpler data, up from 4.2 million bpd last year. That has provided a lifeline for the energy market, helping to keep down global oil prices. Saudi Arabia is considering an expansion of its crude oil pipeline to the Red Sea coast, Reuters reported last week.

When the Houthis launched attacks on Red Sea shipping in November 2023, Gulf oil exports were flowing freely. The Houthis have been in a civil war against the Saudi-backed, internationally recognized government for more than a decade and have attacked Gulf neighbors with missiles and drones.

However, a 2022 truce between the country's warring sides largely held until last week, when Yemen's internationally recognized government said it had struck Sanaa airport to stop an Iranian plane landing. The Houthis said Saudi Arabia was responsible and, in response, fired missiles at Abha airport in the kingdom's mountainous southwest.

A senior Houthi official, politburo member Mohammad al-Farah, then warned in an interview on Iran's Press TV website that if the situation kept escalating, Bab el-Mandeb would be closed. The U.S. says Iran has armed, funded and trained the Houthis with help from Hezbollah.

The Houthis deny being an Iranian proxy and say they develop their own weapons. It is not clear how far the group's stance on Bab el-Mandeb and the Red Sea stems from its own strategic priorities or is being made on Iran's behalf. After Israel's genocidal campaign in Gaza, the Houthis began firing at Israel and on shipping in the Red Sea, saying they were doing so in support of Palestinians.

The attacks severely disrupted global shipping, prompting Maersk, Hapag-Lloyd and other major companies to divert around Africa – a far longer, more expensive route. Red Sea traffic has not recovered since, with traffic through the Suez Canal down 52% in 2025 versus 2023 levels and at its lowest in at least 50 years, Suez Canal Authority data shows.

A U.S.-led mission to restore free navigation in the Red Sea involved repeated strikes on Houthi targets and a campaign that shot down hundreds of drones and missiles. But some Houthi attacks continued until last summer, only ending completely with the Gaza cease-fire in October.

Last month, the Houthis said they would ban ships linked to Israel from the Red Sea after Israel renewed military attacks on Iran. However, that threat was never acted on and shipping groups Maersk and Hapag-Lloyd are resuming some Red Sea routes that they had abandoned during the Houthi attacks last year, Maersk said this month.

While Hezbollah and the Iraqi groups joined the war early with rocket and drone fire after the first U.S. and Israeli strikes on Iran, the Houthis had been comparatively quiet. The group's leader Abdul Malik al-Houthi said on March 5: "Our fingers are on the trigger at any moment should developments warrant it.

" Iranian commanders have repeatedly warned that the Houthis could join the war. The Houthis launched a few missile and drone attacks on Israel in late March and early April. Revolutionary Guards Quds Force commander Esmaeil Qaani said on June 1 they could choke off the Red Sea.

That may now have changed with their announcement of the blockade on Monday against Saudi Arabia in retaliation for what they called the kingdom's siege of its ports and airports, including last week's strike.
