Record $5.7T triple-witching
March 20 produced Wall Street’s largest-ever triple-witching options expiry with about $5.7 trillion in contracts rolling off, sharply amplifying intraday volatility. Trading desks flagged the expiry as a major short-term liquidity event amid a jittery macro and geopolitical backdrop. (economictimes.indiatimes.com)
Citigroup’s breakdown of the quarterly expiry showed $4.1 trillion in index contracts, $772 billion in ETF contracts and $875 billion in single‑stock options. (bloomberg.com) Citigroup’s data marks the event as the largest March expiry on record in its dataset going back to 1996 and the expiring notional represented about 8.4% of Russell 3000 market capitalization. (bloomberg.com) Citi’s Vishal Vivek flagged that index and ETF notional volumes hit record levels in March—roughly 9% above year‑to‑date averages—while single‑stock options volumes ran about 3% below their recent norms. (bloomberg.com) The expiry landed on the same week as S&P Dow Jones Indices’ March 6 rebalance (effective before the open on March 23), which added names including Vertiv, Lumentum and Coherent and forces passive funds tracking the S&P to transact at the March 20 close. (spglobal.com) Volatility readings spiked ahead of the close: the Cboe VIX closed at 25.09 on March 19—its highest level in over two years—and the S&P 500 finished March 20 at 6,606.49 with all 11 sectors in the red. (financialcontent.com) Proprietary trading desks and market‑making desks described the expiry as a concentrated short‑term liquidity event tied to the 3–4 PM ET “witching hour,” with pre‑market notes from Cannon Trading and Bloomberg highlighting mechanical flows that can pin or shove closing prices.
