According to PANews, the U.S. Securities and Exchange Commission (SEC) has initiated a review process for a proposed rule change by the Cboe Exchange. The proposal seeks to amend Rule 5.4(a) to adjust the minimum price increment for Mini Bitcoin U.S. ETF Index (MBTX) options. Under the proposed changes, contracts priced below $3 would have a minimum price increment of $0.01, while those priced at $3 or above would have an increment of $0.05. This adjustment aims to enhance market liquidity and align with competing products such as IBIT options. The SEC will gather public comments before making a final decision on whether to approve the proposal.
