期權大單 | 債券期權成交放量,0DTE期權引爭議
uSMART盈立智投 03-08 17:43

一、市場回顧

美股週二收跌。道指下挫逾570點,抹去今年迄今的漲幅並轉爲下跌,納指、標普500指數均跌超1%。美聯儲主席鮑威爾稱可能加快加息步伐、最終利率水平或高於此前預期。市場擔心美聯儲將在更長時間內維持更高利率。

週二美股期權市場總成交量34,892,124張合約,環比增加約5%。其中,看漲期權佔比50%,看跌期權佔比50%。

二、期權成交總量TOP10​​

幾隻指數ETF,以及特斯拉、蘋果的期權交易依然排名靠前。值得注意的是,債券指數ETF(HYG)的期權交易量有所攀升,排名總榜第九位。

隨着鮑威爾強勢“放鷹”,市場對美聯儲未來四次政策會議的加息預期升溫,2年期美國國債收益率週二攀升13個基點,至5.02%,爲2007年以來的最高水平。但關鍵是,較長期債券收益率仍然停滯不前;儘管本週晚些時候美國將拍賣10年期和30年期國債,但10年期和30年期美國國債收益率收於4%以下,幾乎沒有變化。備受關注的2年期和10年期美國國債收益率之間的息差自1981年以來首次超過一個百分點。

過去幾十年裏,在美聯儲大舉收緊政策之後,收益率倒掛幾乎都可以視爲經濟衰退的預兆。

顯然,債券市場的種種異動,都顯示出投資者越來越擔心美聯儲是否有能力在不顯著損害經濟增長的情況下控制通脹。

目前值得關注的異動來自宏觀層面。

週一,摩根大通的數據顯示,在美股期權市場上,在交易日結束時到期的期權合約——0DTE期權交易激增,每日名義交易量上升至了約1萬億美元。

摩根大通分析師估計,在極端糟糕的情況下,0DTE期權可能會擴大主要美股指數的跌幅,將標普500指數盤中5%的跌幅進一步擴大成25%的暴跌——將是自1987年“黑色星期一”以來的最大跌幅。

1987年10月19日,標普500指數單日暴跌20.5%,道指暴跌22.6%,爲許多投資者宛如夢幻般的“黃金的80年代”畫上句號。

摩根大通稱,如今,如果標普500指數在5分鐘內下跌5%,就可能再次出現這種情況——下跌將首先引發規模達305億美元的0DTE期權相關交易,再將標普500指數的跌幅再擴大20個百分點。

摩根大通還指出,散戶並不是0DTE期權交易量增長的主要驅動力——個人投資者約佔追蹤標普500指數的 SPDR S&P 500 ETF Trust 期權交易量的20%,僅佔標普500指數相關期權日交易量的5%左右。

事實上,摩根大通上個月就曾警告稱,這些期權交易的增加正是加劇美股波動性的最大來源之一。在某些情況下,它們可能引發極端的大規模波動。

不過,美國銀行認爲問題沒那麼嚴重,目前引起市場震盪的因素與2018年時截然不同,0DTE不會引發崩盤。
