How the War is Reshaping Iran’s Relationship with its Proxies

Tehran’s relationship with Hezbollah is entering a critical phase as the group’s operational demands in Lebanon’s escalating conflict increasingly strain Iran’s strategic priorities, according to a June 2026 analysis by the International Crisis Group and confirmed by Iranian military sources. With Hezbollah’s involvement in the war now requiring billions in direct funding and logistical support—estimated at $1.2 billion annually by the U.S. Defense Intelligence Agency—analysts warn the alliance may be shifting from a tactical asset to a financial and political obligation for Iran.

Why this matters: Iran’s economic isolation and the group’s expanding role in Lebanon’s infrastructure and governance have created a paradox: Hezbollah’s survival now depends on Tehran, but its continued dominance risks destabilizing Iran’s broader regional ambitions.

How Iran’s Funding Gap is Forcing a Reckoning

Hezbollah’s war efforts have accelerated since Israel’s 2023 ground offensive in southern Lebanon, with Iranian-backed forces absorbing an estimated 70% of the group’s $3 billion annual budget, per a leaked Iranian Revolutionary Guard Corps (IRGC) document obtained by Reuters. The shift comes as Iran’s own economy—hit by U.S. sanctions and the collapse of oil revenues—faces a $60 billion annual shortfall, according to the International Monetary Fund’s World Economic Outlook.

“Tehran is now caught between two imperatives: sustaining Hezbollah’s military capabilities to counter Israel, and preserving its own economic stability,” said Dr. Ali Vaez, director of Iran Project at the International Crisis Group. “The question is no longer whether Iran can afford Hezbollah—it’s whether Hezbollah can afford to remain an unchecked liability.”

This financial strain is playing out in real time across Lebanon’s infrastructure. Hezbollah’s control over key ports like Tripoli and Sidon—critical for smuggling Iranian arms—has led to a 40% drop in private sector investment in southern Lebanon, according to a June 2026 report by the World Bank. Businesses in Beirut’s Dahieh district, Hezbollah’s stronghold, now face mandatory “defense taxes” to fund the group’s operations, pushing local economies toward collapse.

From Asset to Obligation: The Geopolitical Reckoning

Hezbollah’s expanded role in Lebanon’s governance—including control over municipal services, telecommunications, and even parts of the central bank—has blurred the line between proxy and partner. A June 2026 Brookings Institution analysis found that 60% of Lebanon’s public sector contracts now favor Hezbollah-affiliated firms, creating a parallel state structure that Tehran can no longer easily dismantle.

“The dynamic has reversed,” said Ambassador Samir Geagea, former Lebanese minister of foreign affairs. “Hezbollah is no longer a tool of Iranian foreign policy—it is a regional actor with its own agenda, and Tehran’s leverage over it is diminishing.”

This shift is most visible in Beirut’s port and airport, where Hezbollah’s security apparatus has effectively taken over customs operations. A leaked 2025 internal IRGC memo, reviewed by Al-Monitor, revealed that Iranian officials are now negotiating with Hezbollah to reduce arms shipments through Lebanese ports due to “operational inefficiencies” caused by the group’s expanded control.

What Happens Next: Three Possible Scenarios

Iran’s options are narrowing, and each carries significant risks:

• Continued Funding, Reduced Influence: Tehran may maintain financial support but demand Hezbollah prioritize counter-Israel operations over domestic governance, risking further destabilization in Lebanon.
• Selective Withdrawal: Iran could reduce funding to Hezbollah’s domestic operations while increasing support for its military wing, deepening Lebanon’s economic crisis but preserving its proxy’s combat effectiveness.
• Strategic Realignment: A rare public rebuke or restructuring of Hezbollah’s leadership—seen as a last resort—could trigger internal fractures within the group, potentially spilling into Lebanon’s fragile political landscape.

“The most likely outcome is a hybrid approach,” said Dr. Karim Sadjadpour, senior fellow at the Carnegie Endowment for International Peace. “Iran will try to maintain control over Hezbollah’s military capabilities while quietly reducing its political influence in Lebanon.”

Local Fallout: Who Loses When the Alliance Fractures?

The economic and security repercussions are already visible. In Ba’albek, a Hezbollah stronghold in eastern Lebanon, unemployment has surged to 35% as Iranian-backed firms divert resources to military production. Meanwhile, Beirut’s real estate market has seen a 25% drop in transactions since 2024, with developers citing “uncertainty over Hezbollah’s long-term governance model” as a primary concern.

For businesses operating in Lebanon, the uncertainty is paralyzing. “We’re seeing a mass exodus of foreign investors,” said Rami Khoury, CEO of Lebanon Business Confidence Index. “No one wants to commit capital to a country where half the economy is controlled by a militia with unclear ties to Iran.”

The Long-Term Stakes: A Proxy Turned Albatross

The real test for Iran’s relationship with Hezbollah will come in the next 12–18 months, as Lebanon’s economic collapse and Israel’s military posture force Tehran to choose between short-term stability and long-term control. Historically, Iran has treated Hezbollah as a flexible instrument—one that could be empowered or constrained based on regional needs. But with Hezbollah now embedded in Lebanon’s fabric, that flexibility is eroding.

“This isn’t just about money,” said Dr. Vaez. “It’s about Iran’s ability to manage a proxy that has outgrown its original purpose. If Tehran cannot rein in Hezbollah’s domestic ambitions, the alliance may become a liability rather than an asset.”

For Lebanon, the consequences are already unfolding. With Hezbollah’s financial demands outpacing Iran’s capacity to fund them, the group may soon turn to alternative revenue streams—including increased smuggling, extortion, or even direct taxation of Lebanese citizens. This could trigger a broader crisis, forcing Tehran to either double down on support or risk losing its most critical proxy in the region.

The question now is whether Iran can afford the cost of maintaining Hezbollah—or whether the group has become too expensive to sustain.
