During the Asian and European sessions on Friday, spot gold experienced slight upward fluctuations, maintaining the rebound from Thursday and currently trading around $4520.

A turning point has emerged in the Middle East geopolitical situation. Informed U.S. officials revealed that American and Iranian negotiators have reached a provisional consensus on extending the ceasefire and resuming talks on nuclear issues, finalizing a 60-day memorandum of understanding.

According to these informed U.S. officials, the agreement would extend the three-month ceasefire period by an additional 60 days, with the core agenda clearly focused on arrangements for shipping in the Strait of Hormuz and negotiations regarding Iran's nuclear program.

However, this agreement still requires final approval from U.S. President Donald Trump, and a clear timeline for this approval has not yet been established.

The agreement also specifies reciprocal concessions: the United States will gradually lift its maritime blockade on Iranian ports and ease energy sanctions, allowing Iran to increase its crude oil exports.

Paradoxically, as news of the agreement spread, the U.S. Treasury Department simultaneously intensified sanctions on entities within the Iranian military involved in crude oil sales, continuing a strategy of maximum pressure and adding uncertainty to the implementation of the agreement.

Furthermore, Iran's Revolutionary Guards accused U.S. forces of violating the ceasefire agreement by launching missiles at Bandar Abbas airport, warning that "further violations will face a severe response" and emphasizing their control over the strait.

The power struggle continues, highlighting the fragility of the ceasefire framework. U.S. Vice President Vance confirmed the existence of the provisional agreement on Thursday evening but admitted that "there is no clear timeline for whether or when the President will sign it," revealing that both sides are still negotiating over specific wording details.

Iran has not officially confirmed the agreement's contents. At the time of the agreement's disclosure, signs of strain were already appearing in the U.S.-Iran ceasefire framework. In the preceding 24 hours, Kuwait successfully intercepted a ballistic missile launched by Iran, and U.S. Central Command confirmed this signal of escalating conflict, underscoring the fragility of the geopolitical situation.

The Strait of Hormuz: Core of the Agreement and Current Shipping Status. As the "lifeline" for global energy transportation, arrangements for navigation through the Strait of Hormuz form a core clause of the agreement.

According to the memorandum, Iran is prohibited from imposing tolls in the strait and must clear all naval mines from the shipping lanes within 30 days to ensure "unrestricted" navigation.

Positive changes in strait transit have already emerged. A notice from the Iranian Islamic Revolutionary Guard Corps Navy on May 28 local time indicated that in the past 24 hours, 26 commercial ships and oil tankers had passed through the strait's safe passage after obtaining permission and coordination.

However, Iran continues to emphasize that navigation through the Strait of Hormuz requires permission and coordination. Last night, several vessels attempting to enter the Persian Gulf illegally were intercepted or forced to turn back.

Institutional Outlook and Core Negotiations: Nuclear Issue Remains Key Sticking Point. Regarding the prospects of a U.S.-Iran agreement, Castle Securities maintains a relatively optimistic view. The firm's strategist, Frank Flight, pointed out that two major signals indicate a high likelihood of an agreement being reached. First, Iran's internet connectivity has recovered to 86% of its pre-conflict level, suggesting an expectation of de-escalation. Second, there has been an increase in public appearances by senior Iranian military officials recently, reflecting a reduced risk of escalating tensions.

Flight emphasized that investors may be underestimating the potential for a market rebound triggered by the "timely" reopening of the strait.

Nuclear Issue Negotiations: Disposal of Highly Enriched Uranium and Third-Party Custody Disputes. The nuclear issue remains the core challenge for subsequent negotiations. Data from the International Atomic Energy Agency shows Iran currently holds 440.9 kilograms of highly enriched uranium with 60% enrichment, just one step away from the 90% weapons-grade standard.

The provisional agreement aims to first establish a framework for disposing of this highly enriched uranium, leaving specific details for later refinement. However, disagreements persist between the two sides regarding the disposal of stockpiles and constraints on enrichment activities.

Iran has not yet committed to abandoning its uranium stockpiles. Analysis suggests it may propose having China and Russia act as third-party custodians, but Trump has explicitly stated he "will not accept this proposal."

External Interference: Lebanese Situation Increases Negotiation Complexity. Additionally, Iran has demanded that the agreement include a clause requiring "Israel to cease military operations in Lebanon." Israeli airstrikes on the southern suburbs of Beirut and the port of Sidon on Thursday, resulting in 14 deaths, have further complicated the negotiations, becoming another uncertain factor in the agreement's advancement.

Summary and Technical Analysis: Market expectations are currently leaning towards an agreement being close, prompting a rebound in gold prices. However, the final signing depends on whether the agreement is sufficiently favorable to the United States; otherwise, a situation may persist where a deal seems imminent but remains unattainable. Technically, although spot gold has rebounded significantly and even moved above the 5-day moving average, it remains in a downtrend. The price is still constrained by the mid-line resistance of the descending channel, making it likely that gold will continue its correction in tandem with the U.S.-Iran agreement, which is not easily finalized. However, once the agreement is signed, the market could experience a significant reversal. Thursday's substantial rebound in gold prices was a preview of this potential.

As of 15:45 Beijing time, spot gold is quoted at $4525 per ounce.
