Examples of Low Liquidity Scenarios

Major news or earnings releases can lead to market makers widening their bid-ask spreads or temporarily ceasing to quote, especially for options, making it harder to trade. "No quoting through the number and shortly thereafter until markets start to populate a bit."

Market crashes or significant downturns create low liquidity as many participants want to sell but few want to buy. "No buyers and the market is illiquid. Like when it's crashing."

Unexpected intraday news can trigger automated kill switches in sophisticated market-making systems, pausing quoting and reducing liquidity. "For intraday surprise news, most sophisticated MMs (HFTs especially) have latency-sensitive kill switches that detect anomalous market behavior such as vol spikes, tape acceleration, spread widening on correlated instruments and auto-pause quoting within microseconds."

Illiquid ETFs or options with low trading volume can lead to significant losses if trades are forced at market prices. "My account did have transfer lock but main holdings got liqudated... And that person who got in initially bought hundres of shares of never heard of x2 long etf with 4.79k avg volume and started to buy/sell to open/close 5-10 contracts at a time at market price for 140+ time from 2:28 ET till closing."

Futures contracts are generally more liquid than swaps, but margin calls can create liquidity issues for portfolios if cash holdings are insufficient. "Using futures can be an issue for portfolio liquidity in margin calls are required."

Swaps, especially tailored ones, have higher liquidity risk because they are customized and less standardized, making them harder to unwind quickly. "In a swap, even if it is a TRS, you would have higher liquidity risk beacause its standardized for YOU by your dealer."

Forced selling of investments during a market downturn due to an urgent need for cash exemplifies a personal low liquidity scenario, as it means selling at a loss. "If you need to access your money urgently you maybe be forced to sell at a loss."

Retirees often keep significant cash reserves (e.g., 6 months to 2 years of expenses) to avoid being forced to sell investments during market corrections to cover living costs. "The goal is to have enough liquidity so that you are not forced to sell investments to cover expenses when those investments are at distressed prices."
