我猜是因爲MM需要依靠NSCC的統一結算系統SFT來為發生Default的會員進行清算,目的是防止違約會員因爲空頭倉位爆倉以後遭到不同broker dealer集中清算,導致抛售而引發Archegos的危機。這個從2021年才推出的中央結算服務只針對合規會員,例如broker dealer和agent dealer,也包括他們的客戶GSD/sponsoring members。SFTs are often facilitated and intermediated by brokerdealers and agent lenders (i.e., custodial banks or other institutions that lend out securities as agent on behalf of institutional firms). NSCC only choose those underlying securities price equal or exceeds $5 into the SFT (“Securities Financing Transaction Clearing Service” or “SFT Clearing Service”).
根據DTCC的統計,NSCC需要針對的清算目標(security lending)額度達到1500億美金,SFT的服務範圍專指naked short/FTD。同時NSCC僅為單股股價在5美金及以上的倉位提供中央清算服務,因爲5美金是broker dealer/agent dealer在他們自己的交易系統内為security lending記賬的常見基礎價格,所以NSCC采用這個價格作爲區分會員倉位是否可以進入中央清算系統的標準。
