Binance suffers a record $6.3 billion hack in world’s biggest crypto heist

Hackers just stole $6.3 billion from Binance, which runs the world's biggest cryptocurrency exchange, in the largest crypto heist in history. The massive theft has put a harsh spotlight on how cryptocurrency platforms insure their digital assets against cyberattacks and theft. According to Insurance Journal, underwriting such risks remains a niche business offered largely by specialist insurers in the Lloyd's market and in Bermuda.

Unlike traditional insurance, these policies are tailored to blockchain technology, covering risks like the loss of private keys and wallet breaches. Most standard crime insurance policies do not cover cryptocurrency losses because they were originally designed for physical property like cash and precious metals.

Traditional cyber liability policies also exclude the direct loss of digital funds unless specific endorsements are added. When an exchange suffers a breach, losses are covered through insurance payouts, corporate capital, and emergency reserves. Binance established the Secure Asset Fund for Users in July 2018 as an emergency reserve, which holds roughly $1 billion in bitcoin as of 2026.

However, policies often include strict exclusions for value fluctuations, fraud, and negligent key management. Jacqueline Quintal, who serves as Marsh's financial institutions and digital asset industry leader, explained that firms must understand exactly what is covered before disaster strikes. "Digital asset firms and, increasingly, their institutional clients need to understand precisely what is covered, where exclusions and sublimits apply, and which risks are retained," she told Reuters.

For anyone holding digital assets or managing business online, the takeaway is simple: check your own policies and never assume standard insurance protects digital holdings.
