End‑of‑Month Liquidity in the Treasury Market

Trading activity in benchmark U.S. Treasury securities now concentrates on the last trading day of the month. Moreover, this stepped-up activity is associated with lower transaction costs, as shown by a smaller price impact of trades. We conjecture that increased turn-of-month portfolio rebalancing by passive investment funds that manage relative to fixed-income indices helps explain these patterns.
Has Treasury Market Liquidity Improved in 2024?

Standard metrics point to an improvement in Treasury market liquidity in 2024 to levels last seen before the start of the current monetary policy tightening cycle. Volatility has also trended down, consistent with the improved liquidity. While at least one market functioning metric has worsened in recent months, that measure is an indirect gauge of market liquidity and suggests a level of current functioning that is far better than at the peak seen during the global financial crisis (GFC).
How Has Treasury Market Liquidity Evolved in 2023?

In a 2022 post, we showed how liquidity conditions in the U.S. Treasury securities market had worsened as supply disruptions, high inflation, and geopolitical conflict increased uncertainty about the expected path of interest rates. In this post, we revisit some commonly used metrics to assess how market liquidity has evolved since. We find that liquidity worsened abruptly in March 2023 after the failures of Silicon Valley Bank and Signature Bank, but then quickly improved to levels close to those of the preceding year. As in 2022, liquidity in 2023 continues to closely track the level that would be expected by the path of interest rate volatility.
How Liquid Has the Treasury Market Been in 2022?

Policymakers and market participants are closely watching liquidity conditions in the U.S. Treasury securities market. Such conditions matter because liquidity is crucial to the many important uses of Treasury securities in financial markets. But just how liquid has the market been and how unusual is the liquidity given the higher-than-usual volatility? In this post, we assess the recent evolution of Treasury market liquidity and its relationship with price volatility and find that while the market has been less liquid in 2022, it has not been unusually illiquid after accounting for the high level of volatility.
How Can Safe Asset Markets Be Fragile?

The market for U.S. Treasury securities experienced extreme stress in March 2020, when prices dropped precipitously (yields spiked) over a period of about two weeks. This was highly unusual, as Treasury prices typically increase during times of stress. Using a theoretical model, we show that markets for safe assets can be fragile due to strategic interactions among investors who hold Treasury securities for their liquidity characteristics. Worried about having to sell at potentially worse prices in the future, such investors may sell preemptively, leading to self-fulfilling “market runs” that are similar to traditional bank runs in some respects.
