For most people, an asset is liquid if it can be bought or sold quickly without significantly affecting its price—something that’s become more difficult lately.
Many market participants blame post–financial crisis banking regulations. Designed to make banks safer, the new rules have also made them less willing to take risks. Consequently, most banks are no longer big buyers and sellers of corporate bonds. In the past, banks’ involvement—particularly in high yield—helped keep price fluctuations in check and meant investors could usually count on them as buyers when others wanted to sell.
But because they affect the supply of liquidity, regulations are only part of the story. Several other trends have drastically increased the potential demand for liquidity. These include investor crowding and the growing use of risk-management strategies that use leverage and make it hard for investors to ride out short-term volatility.
In one way or another, these trends have driven investors around the world to behave in the same way at the same time. That distorts asset prices and suggests investors may find that their asset isn’t liquid when they need it to be. If a shock hits the market and a fire starts, each of these trends may act as an accelerant.
Managers who think regulation is the only cause of the liquidity drought probably aren’t seeing the big picture. That could make your portfolio more vulnerable in a crisis.
