Iran-US Conflict Escalates: Hormuz, Red Sea and Oil Market Outlook

Global tensions entered a critical phase in mid-July 2026. On the one hand, a glimmer of diplomatic hope emerged through the offer of a ceasefire between Iran and the United States. However, on the other hand, military escalation continued without any signs of abating, even spreading to vital global shipping lanes.

Diplomacy Amidst the Flames: A Ceasefire Proposal

A senior Iranian official revealed that mediators had proposed a 10-day ceasefire. The goal was to restore the memorandum of understanding (MoU) between Iran and the United States reached last month. Iranian Foreign Ministry spokesman Esmaeil Baghaei confirmed that Tehran had accepted the proposal.

Critical Note: This peace offer coincided with the United States’ tenth consecutive nighttime attack on Iran. Therefore, the public should question whether this proposal represents good faith or simply a strategy to seek respite amidst domestic pressures stemming from the energy crisis.

US Strategic Petroleum Reserves Plunge to Their Lowest Level Since 1983

Data from the US Department of Energy shows that crude oil reserves in the Strategic Petroleum Reserve (SPR) fell by approximately 5.1 million barrels in the past week, to 311.4 million barrels, the lowest level since March 1983. Since the US and Israel launched military operations against Iran in late February, SPR reserves have plummeted cumulatively to 104.04 million barrels as of 17 July.

Why this matters: The SPR was designed to serve as the US national energy safety net in the face of sudden supply crises. The drastic drop to its lowest level in more than four decades demonstrates the immense pressure the Iran conflict is placing on US energy stability and indicates that the government is ‘burning through’ its strategic reserves to cushion domestic oil price volatility caused by the war. This is a warning sign: if the conflict drags on while the SPR continues to deplete, the US will lose its future energy policy cushion, just as instability in the Middle East is escalating.

Houthi Blockade of Saudi Arabia: A New Threat to Red Sea Oil Exports

The Iran-backed Houthi group in Yemen has announced a maritime blockade against Saudi Arabia, threatening millions of barrels of Saudi crude oil exports passing through the Red Sea. The Houthis claim this measure is retaliation for Saudi Arabia’s blockade of the Yemeni capital, Sanaa. Houthi spokesman Yahya Saree announced in a video on social media that the ban on Saudi vessels is effective immediately.

Saudi-Houthi tensions have been escalating since Saudi forces attacked Sana'a airport last week, which the Houthis then retaliated against with attacks on airports in southern Saudi Arabia, the most serious escalation since the 2022 ceasefire.

Multi-layered impacts to watch out for: This blockade adds a new layer of risk to global oil supplies, amidst maritime traffic in the Strait of Hormuz, a route through which around a fifth of the world’s oil supply passes, which has been almost completely paralysed by the US-Iran exchange of fire. With two crucial points in the world's energy routes (Hormuz and the Red Sea) simultaneously disrupted, the world faces the risk of a double supply shock that could potentially drive global oil prices sharply higher in the short term. This also indicates that the Iran-US conflict has now evolved into a multi-front regional conflict involving proxies across various regions, rather than a purely bilateral confrontation. .

Tenth US Nighttime Strike on Iran, IRGC Strikes US Bases in Bahrain and Kuwait

US Central Command (CENTCOM) confirmed that at 4:00 PM EDT on Monday, 20July, the US military launched its tenth consecutive nighttime strike against Iran, claiming it further crippled its ability to attack commercial shipping in the Strait of Hormuz. Iran’s Mehr news agency reported an explosion in Isfahan Province, central Iran.

In retaliation, Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed to have launched attacks on US military targets in Bahrain and Kuwait, targeting a drone maintenance hangar at Bahrain’s Sakhir Air Base, a naval equipment depot at Port Salman, and Camp Arifjan in Kuwait.

Claims of damage from both sides, both the US claim of ‘crippling Iran's capabilities’ and the IRGC’s claim of ‘significant damage’, need to be independently verified, as both sides have a propaganda interest in exaggerating the effectiveness of their respective attacks for domestic legitimacy. Ten consecutive nights of attacks, plus direct retaliatory attacks on US bases in two Gulf states, show that this conflict has gone far beyond the scale of ‘limited operations’ and is now involving countries hosting US bases (Bahrain, Kuwait) in the risk of direct involvement; something that could potentially expand the conflict front to the entire Gulf region.

Strategic Conclusion

Based on the USOIL (WTI) technical chart, the price is showing strong recovery momentum after bouncing off the psychological support area around 67.00 and the long-term trend line, following the outbreak of the US-Iran conflict in late February. Currently, the price movement is testing the crucial resistance area and Support-Become-Resistance (Sb'R) around 82.00-84.00, where this area also coincides with the Moving Average indicator. If buyers are able to break through and hold above this resistance zone convincingly with volume support, there is ample room for upside towards the next resistance target in the range of 94.00 to the upper limit of 100.00. However, a failed breakout risks triggering a short-term correction that will retest the consolidation area below.

Today’s events depict a world moving in two opposite directions simultaneously: diplomatic efforts through the Iran-US ceasefire offer, but simultaneously a military escalation spreading from the Strait of Hormuz to the Red Sea, from Bahrain to Kuwait. Coupled with the economic pressures of the US strategic oil reserves plummeting to a 40-year low, the world is facing a combination of mutually reinforcing geopolitical and economic risks. The big question is no longer whether there will be further impacts on energy prices and global market stability, but rather how quickly and severely those impacts will be felt.
