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

Central banks purchasing government bonds is widely recognized as a tool to ease financial conditions, but the Federal Reserve Bank of San Francisco's analysis highlights a subtler consequence: it directly alters the "price of safety." When a central bank steps in as a large buyer, it drives up the price of government debt and, in turn, compresses the yield investors receive for holding the safest assets. This reduces the return on "risk-free" holdings, effectively making safety more expensive to access for investors seeking income.

The market relevance lies in the ripple effects. As yields on ultra-safe instruments fall, investors are often incentivized to move further out the risk curve—into riskier corporate bonds or equities—in search of comparable returns. This dynamic can inflate asset valuations and reduce the premium investors demand for taking on risk.

Looking ahead, market participants should watch how the pace and scale of central bank balance sheet normalization evolve. As purchases taper or reverse, the price of safety may recalibrate, potentially re-steepening yield curves and re-pricing risk across global markets.
