随着 7 月接近结束,比特币期权市场的持仓结构出现明显变化。Deribit 数据显示,执行价为 6 万美元的比特币看跌期权,已成为该平台未平仓名义价值最高的合约,反映出交易员在进入 8 月前更重视下行保护。

这类看跌期权通常用于对冲价格回落风险。比特币曾在上月短暂跌破 6 万美元,随后又回升至 6.3 万美元上方。价格反弹并未推动看涨押注继续扩大,反而让防御型仓位升温。

6万美元看跌期权升至首位

截至发稿,6 万美元看跌期权的未平仓名义价值约为 11.7 亿美元。相比之下,前一日仍居前列的 7 万美元和 7.2 万美元看涨期权,持仓已明显回落。

在美联储议息会议前,市场一度集中买入这两个高执行价看涨期权,押注比特币会在利率决定后继续上行,甚至升向 7.2 万美元附近。但这一走势并未出现。

美联储会议后看涨仓位回落

周五 08:00 UTC 到期结算后,相关看涨仓位明显减少。CoinDesk 援引数据称,当次到期涉及的比特币和以太坊期权总规模约为 100 亿美元。

  • 7 万美元看涨期权未平仓名义价值降至 9.43 亿美元
  • 7.2 万美元看涨期权未平仓名义价值降至 8.88 亿美元
  • 6 万美元看跌期权未平仓名义价值约为 11.7 亿美元

这意味着,市场此前围绕美联储会议建立的偏多仓位,在到期后并未延续,资金更倾向于保留对下跌的保护。

历史数据显示8月通常偏弱

除持仓变化外,季节性数据也在强化谨慎情绪。CoinDesk 数据显示,自 2013 年以来,比特币 7 月的中位数回报率为 8.61%,而今年 7 月涨幅约为 8.9%,与历史表现大体一致。

但在历史样本中,正收益的 7 月之后,8 月往往表现偏弱。自 2013 年以来,比特币 8 月的中位数回报率为 -7.51%。这也是当前市场情绪转向谨慎的另一项依据。

中位数更能反映多数月份的典型表现,因为它不会像平均值那样,受到少数极端涨跌月份的明显拉动。对波动较大的比特币而言,这一指标更适合观察季节性特征。

整体来看,期权持仓重心从高执行价看涨合约转向 6 万美元看跌保护,显示市场在 8 月前的预期已由追涨转向防守。
