PANews reported on December 31 that, according to an SEC announcement, the U.S. Securities and Exchange Commission (SEC) has initiated review proceedings regarding Cboe Exchange's proposed amendment to Rule 5.4(a). The proposal suggests adjusting the minimum price fluctuation unit for Mini Bitcoin US ETF (MBTX) options to $0.01 for contracts priced below $3 and $0.05 for contracts priced at $3 or higher. This adjustment aims to improve market liquidity and align with competing IBIT options. The SEC will solicit public comments before making a final decision on whether to approve the proposal.
