Key Takeaways
- Piper Sandler believes the Strait of Hormuz will remain largely closed for months, keeping oil supplies tight and pushing crude to new highs this summer.
- The investment bank has little confidence that commercial traffic through the strait will recover to even 50 % of pre‑crisis levels in the near term.
- Although President Trump signaled that an Iran deal is “largely negotiated,” U.S. military actions (self‑defense strikes on Iranian missile sites and mine‑laying vessels) and Iran’s warning that navigation will “have costs” suggest a deal is far from certain.
- Iran’s leadership appears unwilling to compromise, viewing its leverage as strong enough to sustain a prolonged closure.
- The Strait carries about one‑fifth of global seaborne oil; any sustained disruption would sharply affect oil and LNG flows from the Middle East to Asia, Europe, and other regions, with potential ripple effects on the global economy and equity markets.
Piper Sandler’s energy and macro teams released a note warning investors that hopes for an imminent Iran nuclear agreement are premature. The bank argues that, despite optimistic rhetoric from the White House, the Strait of Hormuz will stay largely shut for months, tightening oil supplies and driving prices to fresh summertime peaks. This view comes amid a mixed market reaction: West Texas Intermediate (WTI) futures slipped after Friday’s close but recovered some ground on Tuesday as traders parsed conflicting signals about a possible deal over the long weekend.
The backdrop to Piper Sandler’s skepticism includes a series of U.S. military actions described as “self‑defense strikes” in southern Iran. Those strikes targeted Iranian missile launch sites and vessels that had been placing mines in the Strait of Hormuz. The moves followed President Donald Trump’s Saturday claim that an agreement with Iran had been “largely negotiated,” with details to be announced shortly. However, Iran’s foreign ministry quickly countered that any resumption of navigation through the vital waterway would come at a cost, hinting that Tehran intends to extract concessions before allowing free passage.
Piper Sandler’s analysts express “very little confidence” that commercial traffic through the Strait will rebound to even half of its pre‑crisis level within the next week or month. They cite two main reasons for this pessimism. First, the United States appears reluctant to escalate the conflict further, fearing that a robust Iranian retaliation could destabilize neighboring states and further snarl global supply chains. Second, Iranian leaders seem convinced they hold substantial leverage and are therefore unwilling to accept a compromise that would dilute their strategic position. This combination of U.S. restraint and Iranian intransigence raises the prospect that the Strait’s closure could persist for an extended period.
The Strait of Hormuz is a critical chokepoint for global energy markets. Historically, it has carried roughly one‑fifth of the world’s seaborne oil, as well as significant volumes of liquefied natural gas (LNG) from the Middle East to Asian consumers. Since the recent escalation, tracking data show vessel traffic plummeting to near zero, a stark contrast to the pre‑conflict flow. WTI crude futures, which spiked to nearly $120 a barrel at the outbreak of hostilities, have since retreated to around $94 a barrel. Piper Sandler predicts that if the strait remains blocked, oil could climb back above those wartime highs, delivering a “jolt” to the global economy. Higher energy prices would raise production and transportation costs worldwide, potentially dampening the equity‑market recovery that has been buoyed by lower oil prices since the early‑summer peak.
The note also highlights the broader geopolitical calculus. While the U.S. has avoided pressing a decisive military campaign—recognizing that a full‑scale confrontation could provoke wider regional fallout—it has not ruled out targeted actions aimed at deterring Iranian aggression. Iran, meanwhile, appears to be using its control over the Strait as a bargaining chip, signaling that any return to normal shipping will be contingent on securing favorable terms in any diplomatic settlement.
In sum, Piper Sandler’s outlook casts doubt on the near‑term resolution of the Iran‑U.S. standoff and underscores the Strait of Hormuz’s outsized influence on oil markets. Investors should brace for continued volatility in crude prices, with the potential for new highs if the waterway remains closed through the summer months. The interplay of diplomatic signaling, military posturing, and regional power dynamics will be key determinants of whether the market’s current optimism about an Iran deal proves warranted or premature.
