Israel-Iran conflict may last only as long as their missiles hold out

Israel and Iran are engaged in a missile exchange, with Israel reportedly degrading Iran's missile capabilities through preemptive strikes and air superiority; however, the cost of missile defense, estimated at $285 million per night, raises concerns about the sustainability of Israel's defense, potentially impacting ceasefire considerations as interceptor stocks dwindle, and analysts note that while Israel has had a high interception rate, some Iranian missiles have still struck key targets, including an oil refinery and areas near intelligence headquarters.

Analysis

The ongoing missile exchange between Israel and Iran highlights significant military and economic considerations. Israeli intelligence estimated Iran initially possessed around 2,000 missiles capable of reaching Israel, a stockpile diminished by preemptive Israeli strikes. Since the conflict began, Iran has launched approximately 400 missiles, with Israeli counter-strikes eliminating 120 Iranian missile launchers. Israel claims to have achieved air superiority over Tehran, contributing to a reported decrease in the intensity of Iranian barrages, from over 150 missiles on the first night to just 10 on Tuesday. Despite an Israeli interception success rate exceeding 90% for the 400 missiles fired by Iran, with only 35 making impact, critical targets such as a major oil refinery near Haifa have been hit, taking it offline, and missiles have landed near Israeli intelligence and military headquarters. The financial burden of Israel's defense is substantial, costing an estimated 1 billion shekels (approximately $285 million) per night, primarily due to reliance on expensive systems like the Arrow, whose interceptors cost $3 million each. This financial strain, coupled with dwindling interceptor stockpiles, raises concerns about the sustainability of Israel's defense, which, without resupply, might only be maintainable for another 10-12 days at the current tempo, potentially forcing a rationing of defensive munitions and influencing ceasefire considerations. While Israel is actively targeting Iran's missile production facilities, which could impede Iran's ability to reconstitute its forces long-term, more than half of Iran's current arsenal is believed to remain intact, with an unknown quantity potentially hidden.

Key Decisions for Investors

• Investors should closely monitor the escalating defense expenditures by Israel, estimated at $285 million per night, and the reported limited runway of 10-12 days for its current missile defense capacity without resupply, as this fiscal strain and potential for depleted munitions could significantly impact regional stability and Israeli economic outlook.
• The successful Iranian strike taking a major Israeli oil refinery offline highlights the vulnerability of critical energy infrastructure; therefore, assess portfolio exposure to oil price volatility and companies reliant on secure energy supply chains in the Middle East.
• Given Israel's targeting of Iranian missile production facilities and Iran's diminishing launch intensity, consider the medium-term implications for defense contractors, particularly those specializing in advanced missile defense systems and offensive capabilities, as the conflict's trajectory will dictate future procurement and development needs.
