In brief
Saudi Arabia is coming under increasing pressure to become a direct participant in the widening Iran-US-Israel conflict, with Iranian strikes on Saudi territory, joint US-Saudi strikes on Iran-aligned groups in Iraq, and an escalating confrontation with the Houthis in Yemen.
Renewed Houthi attacks and a maritime embargo threaten Red Sea shipping lanes and are already pushing up war-risk insurance costs, with wider implications for fuel prices, freight costs and supply chains. Businesses and investors with exposure to Saudi Arabia or the wider Gulf should assess their exposure to Red Sea transit risk and to Saudi energy and critical infrastructure.
Saudi Arabia has not been a direct participant in the widening conflict between Iran, the United States (US) and Israel, a position that is becoming increasingly difficult to sustain for several key players in the region.
Before the outbreak of hostilities, Riyadh explicitly stated that it would not permit Saudi territory or airspace to be used for attacks against Iran. Nevertheless, Iran launched attacks towards Saudi territory on 28 February 2026, including Riyadh and the Eastern Province, prompting Saudi Arabia to warn that it would take all necessary measures to defend itself, including the option of responding to the aggression.
However, Reuters reported in May that Saudi fighter aircraft struck Iran-backed militia targets in Iraq during the conflict. Then, on 28 July, US Central Command (CENTCOM) announced that US and Saudi forces had jointly conducted strikes against Iran-aligned groups in Iraq who were accused of targeting US forces and Saudi energy infrastructure.
These strikes see the geography of the ongoing conflict start to expand, with Iran's confrontation with the US now becoming increasingly intertwined with Saudi Arabia's conflict with the Houthis in Yemen, dating back to the Kingdom’s intervention in the Yemeni civil war circa 2015.
In turn, this escalation places renewed pressure on Red Sea shipping lanes along the Yemeni coast. The ongoing issues continue to draw in many regional players.
Back to Yemen
Large-scale fighting between Saudi Arabia and the Houthis was substantially reduced following a 2022 UN-mediated truce, which halted offensive military operations inside Yemen and across its borders. One of the results of the truce is that Saudi Arabia remains a principal supporter of Yemen's internationally recognised government, while simultaneously having spent several years attempting to negotiate a durable detente with the Houthi authorities controlling much of northern Yemen.
However, this arrangement is now rapidly deteriorating.
On 13 July, the Houthis fired missiles towards Saudi Arabia following an attack on Sana'a International Airport which they blamed on Riyadh. Then, on 20 July, the Houthis announced a maritime embargo against Saudi Arabia and their vessels traversing the Red Sea. Saudi, in response, said that threats to commercial vessels transiting Bab el-Mandeb, a chokepoint between Yemen, Djibouti and Eritrea, would be dealt with "swiftly and firmly".
By 25 July, Saudi and American forces were again conducting strikes against Houthi targets, while the Houthis claimed missile and drone attacks against Saudi Aramco facilities at Yanbu and Jizan.
More recently, on 6 August, Houthi attacks on Saudi-backed Yemeni government forces in Marib and Hadramout reportedly killed at least 30 soldiers. Saudi authorities also reported that Houthi shelling in Najran, inside Saudi Arabia, injured 11 civilians.
From Hormuz to the Red Sea
For international businesses, the more immediate issue may be what this escalation means at sea. As discussed previously in our articles Shipping under siege: Houthi escalation drives insurance costs, disrupts trade and Shipping under fire (again) Houthi attacks have already demonstrated how relatively inexpensive drones and missiles can impose significant costs on international shipping without physically closing a maritime chokepoint.
Saudi Arabia has relied heavily on its East–West pipeline to move crude oil? from production facilities in the east of the country to Yanbu on the Red Sea, allowing exports to bypass the Strait of Hormuz. Saudi Aramco reported that the pipeline reached its maximum capacity of approximately seven million barrels per day during the first quarter of 2026 as disruption around Hormuz intensified, but now the oil diverted away from one vulnerable maritime chokepoint is emerging beside another.
The International Maritime Organization has consequently urged ship operators to reassess the risks of Red Sea transit, warning that renewed attacks threaten seafarers, commercial navigation and global supply chains.
As previously examined in Shipping under siege, missiles do not necessarily have to hit a vessel to make a shipping route commercially unattractive: insurance can do that first.
Lloyd's List reported in late July that war-risk premiums for Strait of Hormuz transits had surged back into double digits for some owners as insurers reassessed their exposure to the wider Gulf and Red Sea conflict. War-risk insurance costs for voyages in the southern Red Sea have also risen sharply following renewed Houthi attacks.
Our assessment
For most consumers, the consequences are unlikely to appear as an obvious "Red Sea surcharge". They are more likely to emerge gradually through fuel prices, freight costs, delivery times and eventually the price of goods transported through affected supply chains.
For businesses, the implications are more immediate. Companies trading with Saudi Arabia or the wider Gulf should consider not only whether their cargo physically transits the Red Sea, but whether vessels, counterparties or insurers have exposure to Saudi ports or other entities potentially falling within Houthi targeting criteria.
Investors and businesses operating inside Saudi Arabia should also consider the renewed risk to energy and other critical infrastructure, as The Houthis demonstrated during the earlier phase of the Yemen conflict that attacks do not need to cause prolonged physical damage to generate substantial economic effects.
For Saudi Arabia, all of this presents an uncomfortable strategic choice. Renewed military action may be necessary to protect its border, energy infrastructure and Yemeni allies, but a major confrontation would risk reopening a war Riyadh has spent several years trying to leave behind.
It could also fundamentally alter Saudi Arabia's position in future Yemen negotiations. Riyadh had increasingly been able to present itself as both a party to the conflict and capable of negotiating with the Houthis but renewed direct hostilities make that balancing act substantially harder and increase the likelihood that Yemen's effectively frozen civil war once again becomes an active regional battlefield.
