On Sunday, South Korea's Financial Services Commission shocked markets when it announced it would prohibit stock short-selling until June 2024 to allow regulators to “actively” improve rules and systems, a move analysts said was "unusual” and “unwarranted” when no (obvious) financial crisis or external shock that would lead to a sell-off exists. The news sent Korean stocks surging in early Monday trade.
In a rehash of various short selling bans implemented in the US during periods of market turmoil, the commission announced that trading with borrowed shares will be banned for equities on the Kospi 200 Index and Kosdaq 150 Index from Monday until the end of June.
“Amidst market turmoil, we’ve discovered massive illegal naked short-selling by global investment banks and circumstances of additional illegal activities,” Financial Services Commission Chairman Kim Joo-hyun told a briefing. “It’s a grave situation where illegal short-selling undermines fair price formation and hurts market confidence.”
Lee Bokhyun, governor of the Financial Supervisory Service watchdog, told reporters about 10 global banks will face investigations which account for most short-selling transactions in South Korea.

So does banning short selling ever work out? The New York Fed analysis doesn't seem to think so:
In 2008, U.S. regulators banned the short-selling of financial stocks, fearing that the practice was helping to drive the steep drop in stock prices during the crisis. However, a new look at the effects of such restrictions challenges the notion that short sales exacerbate market downturns in this way. The 2008 ban on short sales failed to slow the decline in the price of financial stocks; in fact, prices fell markedly over the two weeks in which the ban was in effect and stabilized once it was lifted. Similarly, following the downgrade of the U.S. sovereign credit rating in 2011—another notable period of market stress—stocks subject to short-selling restrictions performed worse than stocks free of such restraints.

Recent research on the 2008 bans allows us to assess the costs and benefits of short-selling restrictions. The preponderance of evidence suggests that the bans did little to slow the decline in the prices of financial stocks. In addition, the bans produced adverse side effects: Trading costs in equity and options markets increased, and stock and options prices uncoupled.

Taken as a whole, our research challenges the notion that banning short sales during market downturns limits share price declines. If anything, the bans seem to have the unwanted effects of raising trading costs, lowering market liquidity, and preventing short-sellers from rooting out cases of fraud and earnings manipulation. Thus, while short-sellers may bear bad news about companies’ prospects, they do not appear to be driving price declines in markets.
