Crude Oil Falls as Strait of Hormuz Flows Pick Up, Monthly Rally of 20% Endures

Hormuz Flows Increase, Cooling Oil’s Feverish Rally

Brent futures fell $1.03 to $88 a barrel on Friday, and U.S. West Texas Intermediate lost $1.50 to $82.09, as signs of increased crude shipments through the Strait of Hormuz eased some of the supply fears that have dominated trading since the U.S.-Israeli war on Iran began on February 28. The strait, through which normally flows about a fifth of the world’s crude and LNG, had been effectively blockaded for months, but a gradual resumption of tanker movements is now chipping away at geopolitical risk premiums.

Despite Friday’s dip, both benchmarks are poised to close July with a roughly 20% monthly gain, underscoring how fragile the balance remains. The Houthi militant group in Yemen, aligned with Iran, declared a naval blockade on Saudi Arabia last week, threatening the Red Sea route—a crucial alternative to Hormuz for Saudi crude exports and global trade. A Saudi-led coalition of 14 countries including Egypt, Pakistan and Turkey has announced plans to bolster maritime security in the Bab El-Mandeb Strait and the Red Sea, aiming to safeguard energy chokepoints.

Market analysts said the increased flows are countering the region’s simmering tensions. Daniel Hynes of ING noted that crude is “edging lower as rising Middle East tension is being offset by signs of increased flows in the Strait of Hormuz.” Priyanka Sachdeva of Phillip Nova added that while tanker traffic has continued through both Hormuz and the Red Sea, higher security risks have driven up freight costs and insurance premiums, embedding a significant risk premium in prices. “While prices eased from recent highs, the broader trend remains constructive,” she said.

Decoding the Geopolitics of Oil’s Dual Chokepoint Crisis

The Hormuz Thaw and Its Limits

The reported increase in tanker traffic through the Strait of Hormuz is the first concrete sign that global crude flows are normalizing despite the ongoing U.S.-Israel military campaign against Iran. The strait has remained open but at reduced capacity since the war’s onset, with shippers citing prohibitively high war-risk insurance and naval threats. The fresh uptick — while not returning to pre-war levels — suggests that either geopolitical tensions are de-escalating behind the scenes or that commercial imperatives are overwhelming caution. However, the situation is extraordinarily fragile: any direct Iranian retaliation or a Houthi strike on a large tanker would shut down the chokepoint again and send prices spiking.

The Houthi Factor and Red Sea Insurance Shock

Even as Hormuz navigates a tentative recovery, a new front has opened in the Red Sea. The Iran-aligned Houthis last week declared a naval blockade on Saudi Arabia, threatening the Bab El-Mandeb Strait and the Suez Canal route that carries nearly 10% of seaborne oil trade. In response, Saudi Arabia is building a 14-nation coalition to secure the Red Sea and the Gulf of Aden. While the coalition’s formation is a signal of intent, its ability to protect shipping against asymmetric drone and missile attacks is unproven. The immediate effect has been a sharp rise in war-risk insurance quotes for Red Sea passages, with underwriters reportedly charging surcharges not seen since the Houthi attacks on Saudi Aramco facilities in 2019. This second front means that even if Hormuz flows stabilize, a substantial geopolitical risk premium will remain baked into prices.

Where This Leaves the Oil Price Trajectory

The Friday dip is a reminder that daily price moves are susceptible to shifting perceptions of physical supply. Yet the 20% monthly gain reflects the underlying anxiety: the market cannot price out the possibility of a major supply outage given the unprecedented multi-theater tensions. As ING’s Hynes and Phillip Nova’s Sachdeva observed, the broader trend is constructive, suggesting dips are likely to be bought. Traders will now watch for consistent Hormuz tanker tracking data and any Houthi attack on commercial vessels. For oil importers, the combination of elevated insurance and the spectre of longer shipping routes around Africa is already adding significant freight costs, a burden that will ultimately filter into consumer fuel prices if the Red Sea situation worsens.

What Traders, Shippers and Importers Must Track Now

For oil traders, shipping companies and energy importers, the following near-term steps are critical:

• Track daily Hormuz transit data from satellite analytics firms such as Kpler and Vortexa; a sustained return toward pre-war volumes would signal a further unwind of the risk premium and could push Brent below $85.
• Scrutinize war-risk insurance quotes for Red Sea passages through Lloyd’s and other marine insurance markets; any sharp escalation in premiums would foreshadow a major supply-chain rerouting and a new leg higher for crude.
• Energy importers in Asia and Europe should begin modelling the cost impact of potential Red Sea diversions around the Cape of Good Hope, adding roughly two weeks to delivery times and significant freight surcharges.
• Watch for any Houthi attack on a large crude carrier; a successful strike would likely trigger an immediate $5–10 spike in Brent and could push the oil market into crisis mode.
• For oil producers reliant on Hormuz, especially Saudi Arabia and Iraq, the Saudi-led coalition’s ability to deter Houthi maritime attacks is a crucial metric; monitor coalition naval deployments and any Houthi retaliatory statements.
