The US monetary providers business is on heightened alert for potential cyberattacks amid the unfolding US warfare in Iran, with corporations stepping up monitoring for threats that always rise in periods of geopolitical battle, stated executives and analysts.
The assassination of Iranian Supreme Chief Ali Khamenei final weekend in an air strike has sparked a conflagration within the Center East that has roiled markets globally and stoked issues over the potential for Iran-linked cyberattacks on US monetary providers operations.
Cybersecurity has lengthy been a high precedence for the monetary providers business, which operates essential US infrastructure, together with funds, clearing and settlement techniques, in addition to buying and selling platforms and Treasury markets, making it a high goal of cyberattacks, in accordance with business information.

One other high banking business official stated lenders are very involved concerning the threat of cyberattacks, which they see as doubtless.
US intelligence sees low-level cyberattacks as possible
According to a US intelligence assessment, Iran-aligned “hacktivists” could conduct low-level cyberattacks against US networks, such as distributed denial-of-service attacks (DDoS), whereby hostile actors overwhelm a targeted server with a flood of internet traffic.
Credit rating agency Morningstar DBRS said on Tuesday the most significant risks to global banks and asset managers were likely to be indirect, including sustained higher oil prices and shocks to borrowers, but warned that cyber risks could also rise.
“Iran could increase its cyberattacks against Western entities, including banks,” the credit rating agency said.
US investment bank Lazard’s geopolitical advisory team also this week flagged cyber risks, noting that Iran has demonstrated a willingness to deploy cyber capabilities against commercial targets, including financial systems.
According to a 2025 report by the Financial Services Information Sharing and Analysis Center (FS-ISAC), an industry consortium, the financial services sector was the top target of DDoS attacks in 2024, with the Hamas-Israel and Russia-Ukraine wars fueling a surge in hacktivism.
While the industry has not in recent memory suffered a major disruption due to a hostile attack, smaller-scale DDOS attacks as well as ransomware attacks have disrupted pockets of the market. A 2023 ransomware attack on the US broker-dealer unit of Industrial and Commercial Bank of China disrupted the settlement of some US Treasury trades.
“In light of the ongoing military action in the Middle East, we are coordinating with relevant parties to ensure our ecosystem has continuous access to the latest intelligence and guidance to protect the global financial system,” a spokesperson for FS-ISAC said in an email.
