Two New York Stock Exchange-affiliated exchanges have removed the 25,000 contract position limit on options tied to 11 crypto exchange-traded funds. The changes allow institutions to trade the ETFs as FLEX options, offering customizable terms like non-standard strike prices and expiration dates.

The rule changes, approved by the SEC, bring crypto ETF options closer to how other commodity ETFs are treated. They aim to increase liquidity and trading flexibility. Affected ETFs include BlackRock’s iShares Bitcoin Trust (IBIT), Fidelity's FBTC, and ARKB, among others.
