Israeli Escalation in South Lebanon Threatens Trump-Iran Agreement Stability

The recent intensification of conflict between Israel and Hezbollah in southern Lebanon signals a possible acceleration toward the collapse of a potential agreement between U.S. President Donald Trump and Iran, despite American efforts to separate the two negotiation tracks.

Israeli forces advanced deeper into Lebanese territory, crossing the Litani River and launching extensive military operations that expanded into two new areas.

This Israeli incursion reached the Shuqayf Heights (Al-Bufur) and Wadi Al-Salouqi regions in southern Lebanon as part of the campaign against Hezbollah, which is backed by Iran, despite a ceasefire that has been in place for over six weeks.

The escalation in fighting followed shortly after Washington hosted Israeli-Lebanese talks on Friday, diminishing expectations that the United States and Iran would soon announce an extension of their ceasefire agreement.

Conflict Impact on Iran

The confrontation between Israel and Lebanon represents the most significant consequence of the war for Iran. Clashes between Hezbollah and the Israeli army resumed on March 2, when Hezbollah began launching rockets and drones across the border into Israel to support its ally, Iran.

Both sides agreed to a ceasefire in mid-April but continued exchanging fire, each accusing the other of violating the agreement.

According to the Lebanese Ministry of Health, Israeli attacks on Lebanon since March 2 have resulted in 3,412 deaths and 10,269 injuries as of Sunday.

On Friday, President Trump stated he would soon decide on a proposed extension of the "de-escalation" agreement with Iran announced in early April, providing negotiators time to seek a permanent resolution to the conflict and address the core dispute over Iran's nuclear program and the reopening of the Strait of Hormuz.

Israel is expected to play a key role in any such agreement, while Iran has repeatedly emphasized the necessity of including Hezbollah and has demanded strict incorporation of Lebanon in any potential U.S.-Iran deal.

Concerns Over the Strait of Hormuz

Separately, concerns are rising regarding mines in the Strait of Hormuz, a critical shipping route for oil and gas supplies, according to a memo by analyst Tony Sycamore from IG.

Sycamore noted that these mines "could slow the process of reopening the strait, meaning relief to the oil market will come more slowly even after it reopens," adding that "even if an agreement is reached, it will not lead to an immediate flow of supplies."

Axios reported on Friday that Iran laid additional mines in the Strait of Hormuz earlier last week, shortly after U.S. Secretary of Defense Pete Hegseth warned that attempts to plant more mines would violate the ceasefire.

Approximately one-fifth of global oil and gas flows pass through the Strait of Hormuz, which Tehran effectively closed following U.S. and Israeli strikes on Iran at the end of February.

Concerns over supply disruptions overshadowed weak economic data from China earlier in the week, which showed a slowdown in manufacturing activity.

The escalation between Hezbollah and Israel has heightened fears that the world's second-largest economy could lose momentum due to shrinking exports and cost pressures.

Oil prices rose by more than 2% in early trading on Monday, with U.S. crude futures increasing by $2.17, or 2.48%, to $89.53 per barrel as of 23:12 GMT on Sunday. Brent crude futures also climbed $1.93, or 2.12%, reaching $93.05 per barrel.
