What Recent Rising Conflicts in the Yemeni Civil War Mean for the Region and Global Energy Markets

A sharp escalation began in mid-2026, ending a fragile period of relative calm under a 2022 ceasefire. The escalation happened as Houthi rebels launched missile and drone attacks against Saudi oil infrastructure, while Saudi-backed forces intensified their campaign along the Red Sea coast. This renewed conflict could threaten regional security, international shipping, and global energy stability through the strategic Bab el-Mandeb Strait, showing an uncertain future for the end of the Civil War. 

The War is a long-standing regional conflict that originated from the Arab Spring and the Houthi Movement in the early 2010s, involving military actions by Saudi Arabia. The latest surge in violence follows an offensive by Saudi-backed Yemeni governmental forces to reclaim strategic territory along the Red Sea coast. This campaign was launched after the Houthis, an Iran-backed rebel group, made offensive territorial gains, with the latter taking the coastal city of Mokha. Supported by Saudi airstrikes, government troops successfully recaptured several key positions on [date], including the coastal city of Dhubab, according to reports by the Associated Press. The campaign reflects Saudi Arabia’s growing concerns over Houthi advances and threats to regional maritime security.

In response, the Houthis retaliated with missile and drone attacks against critical Saudi infrastructure, targeting military bases, airports, and energy facilities. Key targets included King Khalid International Airport in Riyadh and a major oil refinery in Rabigh on the Red Sea. While Saudi authorities confirmed casualties and damage across oil facilities, some claims of damage made by the Houthis to particular oil facilities have not yet been confirmed by independent analysis. 

This new escalation, following the fragile 2022 ceasefire, increases global doubts about the safety of the strategic Bab el-Mandeb Strait, a vital choke point connecting the Red Sea with the Gulf of Aden. Statistical data from the U.S. Energy Information Administration illustrates how the conflict influences the global oil market, and average oil flows through the Strait decreased from 8.7 million barrels per day in 2023 to 4.0 million barrels per day in the first eight months of 2024.

This conflict further exposes the limitations of the 2022 United Nations-brokered truce. Although the formal ceasefire expired in October of the same year, it temporarily prevented a return to full-scale warfare. Under the agreement, Saudi Arabia said it would refrain from cross-border attacks and to end its costly military involvement. Meanwhile, the Houthis demanded economic concessions, improved access to ports and airports, and greater political recognition.

However, fundamental disagreements on economic access, political involvement, and military security remain unresolved, and could lead both sides to rearm and fortify their positions if negotiations break down. 

The political diversion has brought global concerns and international enforcement and naval forces to protect shipping routes. The United Nations Operation Prosperity Guardian launched in December 2023, followed by the European Union Operation ASPIDES in February 2024, sharing the common goal of protecting freedom of navigation in nearby waters. 

Recent concerns primarily lie with the Houthis’ attacks on Saudi oil infrastructure, as they would further increase security costs and undermine global confidence in the reliability of Saudi supplies, with the country being one of the largest oil exporters in the world. On October 22, Brent crude futures rose 2.2 percent from $108.82 per barrel to $111.24 per barrel according to Reuters, while war-risk insurance premiums for Saudi-linked tankers calling at Yanbu rose by about 3 percent of a vessel's value by late September.

While Riyadh has sought to mitigate risk by routing crude through its East-West pipeline to the Red Sea port of Yanbu, bypassing the Strait of Hormuz, Houthi capabilities along the Red Sea coast leave even these alternative supply lines exposed. However, attacks on the country’s oil production and refinery facilities can still affect its oil exports during a regional crisis. By doing so, the Houthis may exert much more noticeable pressure beyond Yemeni borders.

Without a permanent political settlement, continued fighting could threaten regional shipping, destabilize energy markets, and deepen the humanitarian and economic consequences of Yemen’s prolonged conflict.
