Who buys Treasuries when the Fed shrinks its balance sheet?
Core argument: The authors find that households and broker-dealers absorbed the additional Treasury supply created by the Federal Reserve's 2017–2019 balance sheet reduction, with household Treasury holdings correlated with hedge fund holdings.
Understanding the marginal buyer of Treasury securities during balance sheet reduction has implications for Treasury yield volatility. Our analysis establishes that households and broker-dealers purchased the additional supply of Treasury securities resulting from the Fed's 2017-2019 balance sheet reduction period. [The “households” sector includes hedge funds, private equity funds, and personal trusts.] We find that Treasury security holdings of households are correlated with hedge fund holdings. Over the first year of the balance sheet reduction that began in June 2022, households purchased a large portion of Treasury securities the Fed no longer holds, but hedge funds did not make those purchases. In addition, we find that insurance companies and the rest of the world increased their holdings of Treasury securities during this period, in contrast to the pre-COVID balance sheet reduction.
