比特幣期權市場在聯準會議息會議前明顯轉向平靜。數據顯示,交易員近一個月持續削減下行保護部位,短期限看跌期權的避險溢價也明顯回落,反映市場普遍預期本週波動有限。

看跌/看漲持倉比回落

Glassnode 數據顯示,以未平倉合約計算的看跌/看漲比,已從 6 月底約 0.76 降至約 0.52。這個指標通常用來觀察市場對下跌保護的需求強弱。數值下降,意味著投資人持有的看跌保護相對減少。

同時,短期限選擇權對下行保護的定價也在回落。衡量看跌保護溢價的 25-delta skew 在一週期限已降至約 4%,而三個月和六個月期限仍維持在 11% 至 12% 區間。

短期波動率維持低位

隱含波動率同樣顯示出類似訊號。一週期限隱含波動率約 34.3%,六個月期限約 40.8%。整條期限結構向遠端抬升,說明市場認為眼前一週相對平靜,更遠期限的不確定性仍在。

  • 一週 25-delta skew 約 4%
  • 三個月至六個月 skew 約為 11% 至 12%
  • 一週隱含波動率約 34.3%

市場押注議息週平穩收場

聯準會利率決議將於週三公佈。目前市場對 7 月升息的定價約只有 15%,這也是短期避險需求降溫的重要背景。以此基準情形來看,選擇權市場對本週波動的低定價有一定依據。

不過,這種部位結構也意味著緩衝空間有限。如果聯準會聲明或經濟預測超出市場預期,目前較薄的保護部位可能會放大價格波動,而不是吸收衝擊。

現貨方面,比特幣上周大部分時間維持在 6.5 萬美元附近。即便美國大型科技股一度出現明顯拋售,加密產業接連出現企業破產與平台收縮消息,比特幣價格整體仍保持相對穩定。
