Yes, the Houthis could very well escalate their Red Sea attacks in direct response to the massive US-Israeli strikes on Iran — and two senior Houthi officials have already announced the group’s decision to resume missile and drone attacks on US and Israeli-flagged ships in the Red Sea and Gulf of Aden. The announcement came on February 28, 2026, the same day Operation Epic Fury killed Iran’s Supreme Leader Ali Khamenei and struck at least nine Iranian cities. After roughly three and a half months of relative calm tied to the October 2025 Gaza ceasefire, the Houthis appear ready to reignite one of the most disruptive shipping crises in modern history.
What remains uncertain is the timing and scale. As of early March 2026, Houthi leader Abdulmalik al-Houthi delivered a speech on March 1 condemning Khamenei’s assassination, but notably did not announce specific military retaliation. The FDD’s Long War Journal characterized the situation plainly: the Houthis have “expressed solidarity with Iran but do not launch retaliatory attacks — yet.” The gap between rhetoric and action is where the real risk lives, and it is that gap that shippers, insurers, military planners, and consumers worldwide are watching with growing anxiety. This article covers the strategic context behind the Houthi threat, the potential shipping and economic fallout, Iran’s broader retaliation posture, what the UN and international community are doing, and what a renewed Red Sea campaign would mean for Yemen itself.

Why Are the Houthis Threatening to Escalate Red Sea Attacks After the Iran Strikes?
The Houthis are an iranian-backed militia that controls much of northern Yemen, and their relationship with Tehran is not merely ideological — it is operational. Iran has long supplied the group with weapons, intelligence, and strategic direction. When the United States and Israel launched Operation Epic Fury on February 28, 2026, targeting IRGC command facilities, air defenses, missile sites, and military airfields across Iran, the Houthis lost their most important patron’s supreme leader. That is not the kind of event a proxy group absorbs quietly. The Houthis had paused their Red Sea shipping attacks beginning around November 11, 2025, roughly coinciding with the Gaza ceasefire reached the previous month.
For about three and a half months, commercial shipping saw a fragile reprieve. But the calculus shifted overnight when the strikes killed Khamenei and members of his family, as confirmed by Iran’s semi-official Fars news agency. The Houthi announcement to resume attacks on the same shipping routes targeted during their 2024-2025 campaign is a direct signal that the ceasefire dividend has expired. It is worth comparing this to the 2024-2025 campaign itself, when Houthi attacks forced the majority of commercial carriers to abandon the Red Sea entirely in favor of the Cape of Good Hope route. That detour adds approximately 3,500 nautical miles and 10 to 14 extra days per voyage. If the Houthis follow through, the shipping industry faces a return to those conditions — or potentially something worse, given the broader regional war now underway.
What Would Renewed Houthi Attacks Mean for Global Shipping Costs?
The financial consequences of a resumed Houthi campaign in the Red Sea would be felt almost immediately. BIMCO, the world’s largest shipping association, has already warned that war risk premiums are likely to increase sharply if attacks resume. These premiums — essentially the insurance surcharge for transiting a conflict zone — could add hundreds of thousands of dollars per voyage. During the 2024-2025 attack wave, some carriers saw premiums spike tenfold, and the cumulative cost was passed directly to consumers through higher prices on everything from electronics to grain. However, the impact depends heavily on whether carriers attempt to resume Red Sea transits or continue routing around the Cape of Good Hope. Many carriers are still security measures — something analysts have speculated could happen by mid-2026 — and the Houthis resume attacks, the resulting insurance chaos and potential vessel damage would be far more disruptive than a continued voluntary diversion. The worst-case scenario is not ships avoiding the Red Sea; it is ships entering the Red Sea and getting hit. The Suez Canal, which connects the Red Sea to the Mediterranean, normally handles roughly 12 to 15 percent of global trade. Every day that traffic is diverted or disrupted ripples through supply chains worldwide. For American consumers, this translates to delayed deliveries and higher retail prices, a pattern already documented during the previous round of Houthi attacks.
Iran’s Broader Retaliation and the Regional Powder Keg
The Houthi threat does not exist in isolation. Iran itself has vowed retaliation for Operation epic fury, and reports indicate missile attacks have already targeted US military facilities in Qatar, Kuwait, the UAE, and Bahrain, as well as strikes on Israel, Jordan, and Saudi Arabia. This is a regional conflict expanding in real time, and the Houthis are one front among several. Defense Secretary Pete Hegseth described Epic Fury as “the most lethal, most complex, and most-precision aerial operation in history.” The US demands issued to Iran — a permanent end to uranium enrichment, strict limits on ballistic missiles, and a complete halt to support for proxy groups including Hamas, Hezbollah, and the Houthis — amount to a call for Iran’s total strategic capitulation.
Tehran is unlikely to comply, which means the cycle of escalation has no obvious off-ramp. For the Houthis specifically, the death of Khamenei creates a complicated internal dynamic. Their patron is gone, but the IRGC infrastructure that has armed and directed them is not entirely destroyed. The question is whether the Houthis act independently out of ideological solidarity, wait for direction from whatever leadership structure emerges in Tehran, or use the chaos to consolidate their own regional position. Each of these scenarios carries different implications for Red Sea security.
What Is the International Community Doing to Address the Houthi Threat?
The UN Security Council adopted Resolution 2812 in 2026, extending reporting requirements on Houthi attacks in the Red Sea for an additional six months. This is a monitoring and accountability measure, not a military response, and it reflects the international community’s limited appetite for direct intervention in Yemen beyond what the US and its allies have already undertaken. The tradeoff here is stark. Military strikes against Houthi positions in Yemen — which the US and UK carried out during the 2024-2025 campaign — degraded some Houthi capabilities but did not stop the attacks. The Houthis operate from deeply embedded positions in mountainous terrain and urban areas, making them exceptionally difficult to neutralize from the air.
A ground campaign would be enormously costly and politically untenable. So the international response largely consists of naval escorts, defensive measures, and diplomatic pressure — none of which have proven sufficient to guarantee safe passage through the Red Sea. Meanwhile, the shipping industry is left to make its own risk calculations. Some carriers may resume limited Red Sea transits with enhanced security measures by mid-2026, but that depends entirely on whether the Houthis follow through on their threat. The gap between a UN resolution and an anti-ship missile is measured in practical security, not legal authority.
The Devastating Consequences for Yemen Itself
One of the most under-discussed aspects of a Houthi escalation is what it would mean for Yemen, a country already devastated by years of civil war and humanitarian crisis. Analysts have explicitly warned that renewed Houthi attacks on Red Sea shipping would have “devastating effects on Yemen” itself, a point that tends to get lost in the focus on global trade disruption. Yemen imports roughly 90 percent of its food and nearly all of its fuel. The ports through which these supplies arrive — particularly Hodeidah, which the Houthis control — are vulnerable to retaliatory strikes and blockade enforcement.
During previous rounds of escalation, aid deliveries were disrupted, fuel prices inside Yemen spiked, and civilian suffering intensified dramatically. The Houthis’ decision to resume attacks is, in a very real sense, a decision to accept further destruction of the country they claim to govern. This is a limitation that rarely enters the strategic conversation. The Houthis frame their attacks as resistance against the US and Israel, but the primary victims of the resulting military response and economic disruption are Yemeni civilians. Any analysis of Red Sea escalation that ignores this dimension is incomplete.
The Gap Between Houthi Rhetoric and Action
As of early March 2026, there is a notable gap between what the Houthis have said and what they have done. Two senior officials announced the resumption of attacks on February 28, and Abdulmalik al-Houthi’s March 1 speech condemned the assassination of Khamenei in forceful terms. But no confirmed retaliatory attacks have been launched. The speech focused primarily on mobilizing demonstrations and media support rather than announcing specific military operations.
This gap could mean several things. The Houthis may be waiting for a coordinated signal from whatever remains of Iran’s command structure. They may be assessing their own military readiness after months of inactivity. Or they may be calculating whether the current US military posture in the region makes an immediate attack suicidal rather than strategic. The uncertainty itself is a weapon — shipping companies and insurers must price in the threat whether or not an attack materializes.
What Comes Next for Red Sea Security
The trajectory of Red Sea security over the coming weeks and months depends on variables that no single analyst can predict with confidence. If the Houthis launch even a handful of successful attacks on commercial vessels, the fragile recovery in Red Sea shipping traffic will collapse overnight, and the Cape of Good Hope route will once again become the default for most carriers. If the Houthis hold off — whether by choice or incapacity — there may be a gradual, cautious return to Suez Canal transits, though war risk premiums will remain elevated for the foreseeable future. The broader question is whether the post-Khamenei landscape in Iran produces more or less proxy warfare.
The US demands for Iran to permanently cut support to Hamas, Hezbollah, and the Houthis are maximalist by any measure. If a successor regime in Tehran doubles down on proxy networks as its primary asymmetric tool, the Houthis may become more aggressive, not less. The Red Sea, in that scenario, remains a flashpoint not just for months but for years. For global commerce, for American consumers, and above all for the people of Yemen, the stakes could not be higher.
Conclusion
The Houthi threat to resume Red Sea attacks is real, specific, and tied directly to the seismic events of February 28, 2026. Operation Epic Fury fundamentally altered the Middle Eastern security landscape by killing Iran’s Supreme Leader and striking military infrastructure across nine cities. The Houthis have responded with a declared intent to resume the shipping attacks that disrupted global trade throughout 2024 and 2025.
While confirmed retaliatory strikes have not yet materialized as of early March, the threat alone is already reshaping insurance markets, shipping decisions, and military planning. What happens next depends on the interplay between Houthi capability, Iranian command continuity, US military posture, and the sheer economic gravity of the Red Sea trade corridor. Shippers, policymakers, and consumers should prepare for a period of elevated risk and uncertainty. The roughly three-and-a-half-month pause in attacks may prove to have been the calm before a far more dangerous storm, and the international community’s tools for preventing that storm remain limited at best.
Frequently Asked Questions
Have the Houthis actually launched new attacks on Red Sea shipping since the Iran strikes?
As of early March 2026, no confirmed retaliatory attacks have been launched despite the Houthis’ announcement on February 28 that they would resume missile and drone strikes on US and Israeli-flagged ships.
Why did the Houthis pause their Red Sea attacks in the first place?
The pause began around November 11, 2025, and was linked to the October 2025 Gaza ceasefire. The Houthis had framed their original campaign as solidarity with Palestinians, so the ceasefire removed their stated justification for attacks.
How much does rerouting around the Cape of Good Hope cost?
The detour adds approximately 3,500 nautical miles and 10 to 14 extra days per voyage. Combined with elevated war risk insurance premiums — which BIMCO warns could increase by hundreds of thousands of dollars per voyage — the total cost per transit rises significantly.
What is UN Security Council Resolution 2812?
Adopted in 2026, Resolution 2812 extends reporting requirements on Houthi attacks in the Red Sea for six months. It is a monitoring measure, not a military authorization.
What did the US demand from Iran after Operation Epic Fury?
The US demanded a permanent end to uranium enrichment, strict limits on ballistic missiles, and a complete halt to Iranian support for proxy groups including Hamas, Hezbollah, and the Houthis.
Could Houthi attacks actually affect prices for American consumers?
Yes. The Red Sea and Suez Canal handle a significant share of global trade. Disruptions during the 2024-2025 Houthi campaign contributed to shipping delays and higher retail prices on imported goods, and a renewed campaign would likely produce similar effects.
