An analyst cited by Bank of America (BofA) argues that the present confrontation involving Iran is unlikely to extend for long, in large part because ordnance and weapons inventories will limit how long high-tempo operations can be sustained.
Evelyn Farkas, executive director at the McCain Institute, "sees the conflict lasting a matter of weeks as concerns from Congress and regional allies put pressure on rapid resolution," BofA noted in its commentary.
Farkas and BofA analysts highlighted recent steps to increase production of munitions and military equipment, but cautioned that such measures may not be sufficient to keep pace with current rates of engagement if fighting continues. As BofA wrote, "Weapons stockpiles are a key pacing item... stockpiles could be strained if the conflict lasts more than several weeks at current rates." The implication is that even with production ramp-ups, available inventories could become the primary constraint on operational tempo.
Beyond the immediate operational timeline, the dispute may affect U.S. defense spending dynamics. BofA analysts noted that, despite partisan divisions in Washington, the crisis raises the probability of Congress approving supplemental military funding. Such extras could partially narrow the distance toward President Donald Trump’s stated $1.5 trillion defense spending objective, though the analysts emphasized that federal budget negotiations remain unsettled.
On the FY27 defense outlook, BofA said the most recent indications contemplated a roughly $1.1 trillion base budget plus $350 billion via reconciliation - a reconciliation package that analysts characterized as likely to be politically unviable. In that context, supplemental appropriations could serve to close part of the shortfall if lawmakers choose to provide additional funds.
The conflict's geopolitical effects would not be limited to the United States and Iran. Farkas suggested that both Russia and China could experience strategic downsides tied to their ties with Iran. At the same time, disruptions to energy markets may create winners and losers: Russia, as a major oil exporter, could see benefits from market dislocations, whereas China - which has historically relied on Iranian crude - could face headwinds.
Despite targeted Iranian strikes on civilian infrastructure in Gulf states, the broader regional spillover risk was judged by Farkas to be relatively low. She assessed that widespread destabilization across the region was not the most likely outcome under current conditions.
Looking further ahead, BofA analysts considered how a longer-term shift in regional power might play out. A balance of power moving away from Iran and toward Israel and Gulf partners could permit greater U.S. disengagement from the region and place a larger share of defense responsibilities on Arab states, requiring higher domestic defense spending from those governments.
On prospective outcomes, the base-case scenario described by those cited involves a diplomatic resolution. Farkas outlined what she viewed as the most probable end state: a new agreement between the United States and Iran intended to remove Tehran’s ability to develop nuclear weapons and certain offensive capabilities, accompanied by ongoing international monitoring.
The analysts also noted a downside scenario in which hardline security forces inside Iran refuse to negotiate with the U.S. and Israel, potentially prolonging hostilities and preventing a negotiated settlement.
