What would be a sign of a shortage in financial markets?

A sign of a shortage in financial markets could be a sharp increase in prices for certain assets, indicating that demand significantly exceeds supply. This might manifest as a rapid rise in stock prices, a spike in bond yields, or a scarcity of available liquidity, making it difficult for investors to obtain funds. Additionally, heightened volatility and widening bid-ask spreads could suggest that market participants are struggling to find adequate assets to meet their needs.
