Binance Introduces Stock Put Options Requiring Full USDC Collateral From Sellers

WHY IT MATTERS

A put option is a contract that gives the buyer the right to sell an asset at a set price. The person who sells (or "writes") that put option takes on the obligation to buy the asset if the buyer exercises the contract. Normally, in traditional stock markets, the seller only needs to set aside a fraction of the money they might owe — this is called "margin." Think of it like a security deposit rather than paying the full amount upfront. Binance is doing things differently by requiring sellers to lock up the entire amount they could owe, using USDC (a stablecoin designed to maintain a 1:1 value with the US dollar). This is like requiring a renter to pay the full lease upfront instead of just a deposit. It reduces the risk that a seller cannot pay what they owe, but it also means sellers need much more capital to participate.
