比特币交易员正悄悄地为冲击做准备。进入 9 月 15-16 日 FOMC 会议之前的期权市场显示出明显的看跌偏斜(put skew),这意味着 25-delta 看跌期权的隐含波动率高于同等看涨期权。当保护成本高于参与成本时,市场正在向你传递信号。

这一差距虽然并不剧烈,但却是有意的。根据该时期的持仓数据,9 月 25 日到期的 25-delta 看跌期权偏斜比同类看涨期权高出约 1.44 个百分点。

当在相同 delta 下看跌期权的隐含波动率高于看涨期权时,做市商正在对非对称需求进行定价:在距离现货价格同等行权价距离的情况下,更多的买家想要下行保护,而非上行风险敞口。

在这种情况下,比特币在进入 9 月中旬时交易价格接近 $80,000,更广泛的期权曲面反映的是谨慎情绪,而非彻底的恐慌。根据 Deribit 的 DVOL 指数追踪,9 月 16 日短期合约的整体隐含波动率维持在 38.9% 左右。这是一个适中的读数,不像在真正的清算螺旋期间看到的那种高企的恐惧指标。

未平仓合约讲述了一个类似的双面故事。看涨期权仍占据主导地位,约占总未平仓合约的 61%,而看跌期权占 39%。看跌偏斜的存在并非因为空头接管了账本,而是因为一部分交易员愿意专门为短期合约的保险支付溢价。

在以看涨期权为主的整体持仓背景下,短期到期合约的看跌溢价升高,指向的是事件驱动的对冲,而非向看跌情绪的广泛结构性转变。

2026 年早些时候,在 7 月 FOMC 窗口期前后,情况明显不同。在那段时期,短期看跌对冲被平仓,使 25-delta 偏斜收缩至 4% 左右。9 月的读数代表了相对于夏季基准的防御性头寸的实质性提升,表明市场的风险感知在间隔的几个月中发生了变化。

数据中的这种双重性——看涨的整体持仓与升高的短期看跌溢价并存——为任何试图预测 FOMC 后价格走势的人创造了一个复杂的信号。它并没有明确表明市场预期会出现抛售。它表明市场希望在保持上行风险敞口完整的同时,为可能的抛售做好准备。

交易员付费构建的这种非对称性(看跌期权的 IV 高于看涨期权),本质上锁定了一种情景,即下行波动的速度和幅度可能比同等程度的上行波动更快、更陡峭。这就是下行凸性在实践中的真正含义:在事件前后的短时间内,期权市场的定价使得看跌走势比看涨走势更具加速效应。
