比特币期权市场的波动预期正在降温。Volmex 的 BVIV 指数周末跌至 35.59%,为 2025 年 9 月以来最低水平,显示市场对未来 30 天大幅波动的押注明显减少。

不过,这并不意味着交易员已经转向乐观。当前看跌期权仍比看涨期权更贵,说明短期虽然缺少明确方向,但防范价格继续下探的需求并未消退。

BVIV跌至35.59%

比特币自 7 月初以来大致维持在 6.2 万至 6.6 万美元区间,现货波动收窄,期权需求也随之减弱。相比之下,BVIV 在今年 2 月曾一度升破 90%,当时比特币从 9 万美元附近快速跌向 6 万美元。

BVIV 衡量的是比特币未来 30 天年化隐含波动率,常被视为加密市场的“恐慌指数”。该指标回落,反映出交易员对短期剧烈波动的预期明显降温。

矿企与企业持续卖期权

FalconX 衍生品业务负责人 Griffin Sears 表示,近期指标下行,主要源于期权市场供需失衡。价格长时间横盘后,交易员对双向大行情的押注减少,买入期权的意愿走弱。

与此同时,市场供给仍然偏高。越来越多的参与者,包括比特币矿企和企业财库,正通过系统化备兑策略持续卖出看涨期权,以现货持仓换取额外收益,这也压低了隐含波动率。

看跌保护溢价仍在

尽管整体波动率预期下降,看跌期权相对看涨期权仍维持较高溢价。这说明市场并不预期比特币马上出现大涨大跌,但对下行风险的防范并没有放松。

部分专业交易员也已从直接押注波动率上升,转向交易不同到期日之间的定价差异,以及看跌保护的额外溢价。市场传递出的信号更接近“低波动,但仍防跌”。

比特币抵押借贷平台 Arch 联合创始人兼首席技术官 Himashu Sahay 认为,隐含波动率下降可能带来虚假的安全感。对使用杠杆的借款人来说,融资看似更便宜,但仓位也可能因此变得更激进,一旦价格突然大幅波动,仍可能触发被动平仓。
