President Donald Trump on Thursday extolled the results of his administration's memorandum of understanding with Iran, touting falling oil prices, rising stock markets, and a renewed commitment that Tehran will never obtain a nuclear weapon.

"Oil is flowing, Iran can never have a nuclear weapon (the world will be safe!), the stock markets are roaring, jobs are at records, and prices are dropping (affordability!)," Trump posted in all-caps on Truth Social.

"Our country is strong, safe, and respected like never before," he added. "'You're welcome!'"

Trump's comments came after the U.S. and Iran signed a preliminary agreement aimed at ending hostilities and opening a 60-day negotiating window toward a broader settlement.

The agreement is expected to focus on Iran's nuclear program, sanctions relief, verification measures, regional security, and commercial shipping through the Strait of Hormuz.

Oil prices fell Thursday after the signing, with markets reacting to expectations that Iranian supply and Persian Gulf shipping routes could begin normalizing.

Barron's reported Brent crude and West Texas Intermediate both dropped, while the national average gasoline price slipped below $4 per gallon.

The Wall Street Journal reported that the signing reduced the geopolitical risk premium in oil markets as traders anticipated a gradual restoration of flows through the Strait of Hormuz.

The agreement, according to multiple reports, includes provisions designed to reopen the critical energy choke point and reduce military escalation in the Gulf.

Other reported terms include a 60-day period for negotiations over Iran's nuclear activities and the future of its enriched uranium stockpile.

Trump has framed the memorandum as proof that his pressure campaign and military posture forced Tehran to accept limits while delivering immediate economic benefits to Americans.

He has also warned that the U.S. could resume military action if Iran violates the framework.

Critics, including some Republicans, have questioned whether the agreement gives Iran too much economic relief too soon.

Reports have described possible sanctions waivers, oil-export relief, and future access to frozen assets or reconstruction funding, though the administration has stressed that any long-term benefits for Tehran would depend on compliance.

The Guardian reported that sanctions relief is tied to progress on nuclear negotiations and that the deal remains fragile, with key disputes unresolved.

The New York Post reported that the 14-point framework begins a 60-day clock for negotiators to address Iran's nuclear ambitions and enforcement terms.

Supporters argue the deal could lower energy prices, stabilize global markets, and prevent a wider Middle East war.

Trump, in his Thursday post, credited the memorandum with boosting confidence at home and abroad, saying the results are already evident in oil flows, markets, jobs, and prices.
