Key facts
- Underwriters are expected to ask crypto clients about their exposure to Binance and to weaknesses identified in the attack, the insiders and experts said.
- Binance's report said hackers used a bogus job interview and software hidden in an advertisement to compromise two engineers' computers.
- No available crypto insurance could cover a $6.3 billion loss, and Lloyd's policies have generally excluded state-backed attacks since 2023, Marcos Alvarez said.
- Insurers are not expected to broadly retreat from crypto or reduce coverage availability, Marsh's Jacqueline Quintal said.
- Grand View Research projects the global crypto insurance market at $192.7 billion by 2033, up from $13.8 billion in 2026.
Insurers are expected to ask crypto companies more questions about their security when they seek new coverage or renew policies, following the $6.3 billion theft from Binance on Thursday, November 5, 2026, industry insiders and experts told Reuters. Underwriters are not expected to broadly retreat from the sector or reduce the availability of coverage, but they are expected to examine whether clients are exposed to Binance and to any weakness identified in the attack.
According to a Binance report published the week of November 2, hackers used a bogus job interview and software hidden in an advertisement to compromise the computers of two Binance software engineers, then used a third computer to drain $6.3 billion worth of crypto. The multi-stage campaign began in June and set off a series of security breaches. The FBI has blamed a North Korea-linked group; Pyongyang has denied allegations involving state-linked cyber units.
"Insurers will be asking questions specific to Binance. Their first question will be very simple: what is your exposure to them and do you have any money with them?" said David Rogers, managing director of financial institutions at Gallagher.
Jacqueline Quintal, financial institutions and digital asset industry leader at Marsh, said she did not anticipate material changes in insurance capacity, pricing or coverage, but expected insurers to ask clients more questions, including whether they could be exposed to a similar attack. Peter Hardy, a London-based insurance lawyer at Reed Smith, said that if the investigation shows a specific weakness or flaw in Binance's security, other insurers can expect a requirement for that flaw to be resolved.
The scale of the loss exceeds what any available crypto policy could cover, the experts said, and policies have generally required exclusions for state-backed cyberattacks at Lloyd's since 2023. Marcos Alvarez, managing director of global financial institution ratings at Morningstar DBRS, said the Binance loss exceeds the capacity of any available policy. "If an attack is attributed to a state, insurers may dispute or deny claims. The effectiveness of these exclusions in a major, geopolitically driven loss remains untested," he said.
Alan Lyons, co-chair of the Insurance, Reinsurance & Dispute Resolution Group at Herrick, said a loss of this size prompts underwriters to re-examine their whole crypto book, reassessing aggregate exposure, wordings and sub-limits across the portfolio, and said the predictable response is tighter wordings and clearer exclusions. Grand View Research projects the global crypto insurance market will grow to $192.7 billion by 2033 from $13.8 billion in 2026.
Crypto exchanges quickly moved to bolster defenses and push for greater information sharing after the attack, Reuters reported.
