When an underwriter goes through a smart contract term sheet for the first time, there’s a certain silence. It’s not precisely confusion. The gradual realization that the object in front of them doesn’t behave like a contract at all is more akin to recognition. It acts in a machine-like manner. Furthermore, insurance was never designed to underwrite machines that make their own decisions, despite its actuarial tables and risk models.
The so-called legal loophole for smart contracts resides in that gap. There isn’t a single rule or a statute that is lacking. There is a structural mismatch. Conventional commercial insurance makes the assumption that anyone can read, understand, and debate a contract, including judges, attorneys, and arbitrators. Once implemented on a blockchain, a smart contract simply runs. The payout is triggered if a flight is delayed. Money moves if a shipment doesn’t reach the coded deadline. The phrase “wait, that’s not quite what we meant” does not have a pause button.
Insurance companies have taken notice. According to reports, a number of mid-sized commercial carriers have begun refusing to write policies that are directly linked to algorithmic execution layers in favor of only insuring the human-language agreement that sits next to the code, if one exists at all. It’s not a dramatic retreat, but rather a quiet one. Not a single press release. Only exclusion clauses are added by underwriters, or the business is courteously passed on entirely.
A portion of the hesitancy stems from a question that sounds almost philosophical but has very real financial ramifications: who is responsible when the code follows instructions exactly and ends up doing the wrong thing? A bug is not fraud. In any conventional sense, a defective oracle feed is not negligence. However, insurance is meant to address the issue of who pays when someone loses money. In many situations today, the truth is that no one is completely certain.
Another issue that frequently comes up in discussions with those who actually work in this field is irreversibility. On the majority of blockchains, a smart contract is finished once it is executed. No easy reversal, no clawback. In contrast, a disputed payout can be halted, looked into, and fixed in a traditional claims procedure. Insurance companies base entire departments on this adaptability. It is eliminated by algorithmic agreements by design, which is both what makes them effective and what worries risk officers.
It’s important to remember that none of this indicates that smart contracts are irresponsible or doomed. The technology has already shown promise in more specific applications where the conditions are straightforward and the data feeds are reliable, such as supply-chain triggers, flight-delay payouts, and parametric crop insurance. Those appear to be easily underwritten by insurers. The more ambitious version—contracts that interpret their own terms, resolve their own disputes, and fail to hold a clear party accountable when something goes wrong—is what they are avoiding.
Though slowly, regulators are keeping an eye on this. Enabling laws, like those that a few U.S. states have already passed for blockchain transactions, are thought to eventually close the loophole by making it clear who is accountable for code behavior. Until then, the safest presumption for any company using algorithmic agreements is that they are not protected by the contract that runs the code. The paper version is still important. Perhaps more than before.
