Introduction

The three-month Gulf conflict has finally seen a potential turning point. US President Trump signed an interim agreement aimed at ending the war with Iran and reopening the Hormuz Strait, completing the document electronically, making the agreement take effect significantly earlier. The White House sees this as a pragmatic move to avoid further regional conflict escalation and stabilize global energy supply; however, it has stirred controversy domestically, especially within Republican circles, with many believing it essentially hands a "victory signal" to Tehran.

Based on currently disclosed information, this is not a final agreement to resolve all contradictions but more of a "buffer arrangement" to buy time for subsequent political negotiations. It tries first to solve the most urgent and dangerous issues—ceasefire, navigation safety, oil transport resumption, and sanction adjustments—while leaving more complex topics like nuclear issues, missile problems, and what economic benefits Iran may receive for later 60-day consultations. This arrangement shows diplomatic flexibility on the surface but also means the crisis is not truly over; it has merely shifted from military confrontation to a more delicate political game.

I. Agreement Takes Effect Early: Crisis Management Prioritized Over Resolution

According to US officials and Iranian state media, the two sides signed the interim peace agreement electronically on Wednesday evening. US officials further stated that the relevant memorandum of understanding has taken effect, but whether the Hormuz Strait is fully reopened remains to be confirmed. For global markets, this detail is critical: the Hormuz Strait is not only a key chokepoint for Middle East energy exports but also a barometer for global oil prices and shipping safety.

The draft agreement shows the strait will reopen quickly, and oil sanctions on Iran will immediately be lifted. In other words, the core logic is clear: restore navigation and energy flows first, then use that as a foundation to advance more complex political negotiations. This approach is not uncommon in international crisis management; for realist diplomacy, preventing the situation from spiraling out of control is often more urgent than solving all disputes at once.

Trump previously stated the agreement was originally scheduled for signing on June 19 to allow time for clearing mines in the strait. But the accelerated signing indicates the White House judged the situation had reached a point where "hitting the brakes" was necessary. With the conflict lasting three months, energy supply from the Gulf region significantly reduced, and global economic pressure mounting, the US government apparently feared the regional war could escalate into broader international financial and trade turmoil.

II. From Military Conflict to Economic Risk: Why Trump Chose to Stop

Speaking at the G7 summit in France, Trump said the military escalation "could have triggered a global depression." This remark reveals the important context for his policy shift: for the US, the cost of continuing to escalate conflict began to exceed the strategic benefits from maintaining military pressure.

On one hand, the Gulf region is critical for world energy supply. If the Hormuz Strait remains closed for long, oil prices will surge, affecting transportation costs, manufacturing costs, and financial market expectations. On the other hand, domestic US economy and electoral politics also put pressure on the president. An overseas war with no clear win can undermine governance credibility and intensify domestic anti-war sentiment.

Thus, from a strategic perspective, Trump signing the interim agreement is not purely a concession but more of a response to real pressure. He tries to exchange limited compromise for greater systemic stability, preventing the Middle East situation from further spilling over into the global economic system. For him, preventing market disorder and controlling energy risk may be more aligned with current interests than maintaining a hardline stance.

III. Controversy Over the Agreement: Conflicting Victory Narratives and Political Divisions

Although the agreement eased tensions, it did not gain unanimous support in the US. Some Republicans criticized it as handing Tehran a "victory." In their view, Iran not only obtained oil sanctions relief but may also receive a $300 billion development fund arrangement, while the US prepares to release some frozen Iranian assets. These moves will certainly be interpreted by opponents as a US retreat.

Trump is aware of this criticism, so he repeatedly emphasized that the agreement would not use US government funds, and the fund would only benefit if Iran "behaves well." He also warned that if Iranian leaders do not comply, the US military would relaunch strikes. This phrasing shows the White House aims to use a "carrot and stick" approach to send a détente signal while retaining coercive deterrence.

But the problem is that the interim agreement itself is built on high uncertainty. It requires all parties to stop the most dangerous confrontation in the short term but does not fundamentally resolve each other's core security concerns. For hardliners, such an arrangement is too lenient; for moderates, it is the necessary cost of avoiding war. The existence of divergence means that the implementation process may be more difficult than the signing.

IV. Most Thorny Issues Postponed: Nuclear Issues, Missile Questions, and the 60-Day Window

The most notable feature of the current agreement is that it leaves many contentious issues for negotiation within the next 60 days, including Iran's highly enriched uranium stockpile, nuclear program prospects, ballistic missile projects, and possible further economic arrangement. Trump himself acknowledged that the 60 days are not a "hard" deadline, as long as Iran "behaves well."

This shows that the two sides are essentially establishing a phased political framework rather than signing a comprehensive peace treaty. For the US, nuclear and missile issues remain core security concerns; for Iran, lifting sanctions and rebuilding the economy are practical needs. Neither side can meet all of each other's demands in a short time, so freezing the conflict first and then negotiating substance becomes the only feasible path.

Notably, Trump publicly defended the agreement for not covering Iran's ballistic missile program, saying Iran "must have some because other countries have some." This attitude is significantly more pragmatic and transactional compared to earlier hardline positions. Rubio had argued that Iran's missile and drone capabilities could provide protection for developing nuclear weapons, while Trump tries to leave such issues for subsequent talks to avoid the agreement collapsing at the outset due to too many topics.

V. Reopening of the Hormuz Strait: The Most Sensitive Real Variable for Global Markets

Among all consequences, the market is most sensitive to whether the Hormuz Strait actually resumes traffic. This affects not only crude oil exports but also insurance rates, shipping costs, route stability, and international energy price trends. Even if the agreement is nominally in effect, if clearing, mine removal, security deployment, and navigation mechanisms are not simultaneously completed, market expectations will remain fragile.

Trump stressed that reopening the strait will shift market focus to shipping companies. This assessment is accurate. For shipping companies, energy traders, and insurance institutions, what truly matters is not just "whether there is an agreement" but "whether the agreement can be stably implemented." If the ceasefire is shaky, mine threats not fully eliminated, or local attacks still possible, the risk premium in capital markets will not quickly retreat.

In other words, the agreement brings not immediate security but limited predictability. It allows global markets to temporarily extricate themselves from extreme fears of "full-blown war," but risk does not disappear. In the coming weeks, markets will continue to watch whether Iran fulfills the agreement, whether the US eases sanctions, whether the strait returns to normal traffic, and whether both sides will use the negotiating window to advance deeper strategic exchanges.

Conclusion

Trump's signing of the interim agreement to reopen the Hormuz Strait marks a new phase in this three-month Middle East crisis: military conflict temporarily suppressed, diplomatic game formally taken over, and global economic pressure becoming an important force for compromise. The significance of the agreement is that it avoided the worst-case scenario; but its limitations are equally obvious—most fundamental contradictions are still deferred. The success or failure of the next 60-day negotiations will determine whether this agreement is a step toward lasting peace or a brief ceasefire before the next round of confrontation.

For the US, this is a crisis de-escalation operation with strong realist overtones; for Iran, it is a strategic breather exchanging détente for space; and for global markets and shipping systems, it is more like an ongoing risk management experiment. Whether the agreement can ultimately translate into stable order depends not only on the text itself but on whether both sides are truly willing to find a sustainable balance among security, sanctions, and regional influence.
