Central Bank Bond Purchases and the Price of Safety - Federal Reserve Bank of San Francisco

The Federal Reserve Bank of San Francisco has released analysis examining how central bank bond purchases influence the "price of safety" in financial markets. This research addresses a key mechanism of quantitative easing: when a central bank buys government bonds, it reduces the supply of ultra-safe, liquid assets available to private investors. As a result, the premium investors are willing to pay for safety and liquidity adjusts, which can push yields lower and encourage a shift toward riskier holdings.

This development matters for market participants because central bank balance sheet policy continues to shape financial conditions even when policy rates are unchanged. The analysis helps clarify how large-scale asset purchases transmit through the pricing of safe assets, with consequences for risk premia across equities, credit, and other fixed income instruments.

For investors, the takeaway is that the scarcity of safe assets is a subtle but persistent driver of market behavior. Watching changes in central bank holdings—not just rate decisions—can offer a more complete picture of how yields and risk appetite are being influenced.
