(Reuters) - Trading in new near-dated U.S. options contracts can supercharge volatility in U.S. stocks, potentially leading to tremendous intraday declines, analysts at JPMorgan (NYSE:JPM) said.

The U.S. equity options market has seen a rise in the trading of options contracts set to expire at the end of the trading day - dubbed 0DTE (zero day to expiry) options - with their daily notional value rising to about $1 trillion, according to JPMorgan data.

Their recent growth has been eyed as one cause of intraday volatility, with JPMorgan's Marko Kolanovic last month warning they could spark a massive volatility event under certain circumstances.

In a Monday note, the bank’s analysts attempted to further quantify the derivatives’ potential impact, estimating that in an extremely dire scenario, 0DTE options could turn an intraday 5% drop in the S&P 500 into a 25% rout - a magnitude of decline not seen since the Black Monday crash of 1987, when the index fell 20.5%.

Such a scenario could occur if the S&P 500 fell 5% in five minutes, triggering $30.5 billion in 0DTE option-related trading that would tack another 20 percentage points onto the index's decline, the bank’s analysts said.

If the S&P 500 fell between 1% and 5% in five minutes, it could lead to an unwinding of positions in the range of $6.6 billion to $14.2 billion, translating to an additional 4 to 8.1 percentage points of decline, JP Morgan's analysts said.
