ChainCatcher 消息，芝加哥商品交易所（CME）比特币期货市场持续走弱，数据显示 2026 年 3 月日均未平仓合约（OI）已降至 80 亿美元以下，4 月初进一步降至约 72 亿美元，创 2024 年 2 月以来新低，且已连续第五个月下滑，同时 3 月月度交易量降至 1630 亿美元，较 2025 年 1 月峰值近乎腰斩。
市场分析指出，此轮下滑主要源于“基差交易”（basis trade）的大规模平仓，此前机构通过买入现货 ETF 并做空 CME 期货获取价差收益，是推动 CME 持仓增长的核心动力，但随着比特币价格自 12 万美元高位回落至 7 万美元下方，年化基差收益显著压缩。当前约 5% 的基差收益已接近约 4.5% 的无风险利率水平，在叠加资金成本与对手方风险后，套利空间基本消失，促使杠杆资金撤出。
