On this put up, we look at the evolution of U.S. Treasury market liquidity over the previous yr, which has witnessed myriad financial and political developments. Liquidity worsened markedly one yr in the past as volatility elevated following the announcement of higher-than-expected tariffs. Liquidity shortly improved when the tariff will increase had been partially rolled again after which remained pretty steady thereafter (via the top of our pattern in February 2026), together with after the latest Supreme Courtroom choice hanging down the emergency tariffs and the following announcement of recent tariffs.
Why Treasury Market Liquidity Issues
The U.S. Treasury market is the most important securities market on this planet, with greater than $30 trillion in marketable debt excellent as of February 28. The market is utilized by the Treasury Division to finance the U.S. authorities, by the Federal Reserve to implement financial coverage, and by monetary establishments to handle rate of interest threat and worth different securities. Liquidity is important to all of those makes use of and is subsequently adopted carefully by market individuals and policymakers.
How We Measure Treasury Market Liquidity
We outline market liquidity as the price of shortly changing an asset into money (or vice versa). As in our previous Workers Report, we have a look at three liquidity measures, estimated utilizing high-frequency information from the interdealer market: the bid-ask unfold, order e book depth, and worth affect. The measures are calculated for essentially the most just lately auctioned (on-the-run) two-, five-, and ten-year notes over New York buying and selling hours (outlined as 7:30 a.m. to five p.m., Japanese time).
Volatility and Information over the Previous Yr
As a result of volatility is tightly linked to Treasury market liquidity (see this LSE put up, for instance), we first assess worth volatility round necessary information occasions since April 2025. Volatility displays the uncertainty that always emanates from financial and political developments. We measure so-called realized volatility (volatility primarily based on precise worth variation) at a each day degree for a similar securities—and utilizing the identical information—employed for our liquidity measures.
The chart under exhibits that volatility rose sharply after the April 2, 2025 tariff announcement, peaking between April 7 and April 9. Treasury yields initially declined following the April 2 announcement (maybe on account of flight-to-safety habits by buyers), with the ten‑yr yield declining from about 4.2 p.c to as little as 3.9 p.c on April 4 earlier than closing the day at about 4.0 p.c (see the slide deck accompanying this Could speech by Roberto Perli, supervisor of the System Open Market Account).
Volatility Trended Down after April 2025 Spike
Notes: The chart plots five-day transferring averages of worth volatility for the on-the-run two-, five-, and ten-year notes within the interdealer market from January 2, 2020 to February 27, 2026. Worth volatility is calculated for every day by summing squared one-minute returns (log modifications in midpoint costs) from 7:30 a.m. to five p.m., annualizing by multiplying by 252, after which taking the sq. root. It’s reported in p.c. Drop strains flag the peaks within the five-day transferring common for the ten-year word, that are centered round March 11, 2020, March 14, 2023, and April 8, 2025.
In the beginning of the subsequent buying and selling week, the ten-year yield opened decrease than Friday’s shut however rose quickly, from about 3.9 p.c to 4.5 p.c, or roughly 60 foundation factors, between 8 p.m. on April 6 and midnight two days later. Some analyses recommend the unwinding of swap unfold trades contributed to the rise in yields whereas others level to foreigners’ decreased willingness to carry Treasuries. On April 9, President Trump introduced that a lot of the new country-specific tariffs had been being postponed for 90 days. The ten-year yield declined sharply that day, later ending the week about 20 foundation factors increased than its degree on the time of the April 2 announcement.
After April 9, volatility shortly declined to extra regular ranges and continued trending down in subsequent months as further tariff-related information was introduced: the implementation of the reciprocal tariffs, the Supreme Courtroom choice hanging down the tariffs, and the quick imposition of new short-term tariffs. There was a blip up in volatility in February 2026 across the releases of the employment report (February 11) and client worth index (February 13) however not across the Supreme Courtroom choice (February 20). Be aware that our evaluation ends with the final buying and selling day of February 2026 and therefore doesn’t mirror results from the battle with Iran, which began the subsequent day.
Market Liquidity over the Previous Yr
The bid-ask unfold is the distinction between the bottom ask worth and highest bid worth for a safety, with a wider unfold suggesting worse liquidity. Bid-ask spreads, proven within the chart under, widened markedly after the April 2 tariff announcement, albeit a lot lower than in March 2020 and even considerably lower than in the course of the March 2023 regional banking turmoil. Bid-ask spreads narrowed after the April 9 announcement that the brand new tariffs had been largely being postponed and since then have been much like ranges usually noticed lately.
Bid-Ask Spreads Had been Comparatively Steady after April 2025 Widening
Notes: The chart plots five-day transferring averages of common each day bid-ask spreads for the on-the-run two-, five-, and ten-year notes within the interdealer market from January 2, 2020 to February 27, 2026. Spreads are measured in 32nds of some extent, the place some extent equals one p.c of par. Drop strains flag the peaks within the five-day transferring common for the ten-year word, that are centered round March 16, 2020, March 15, 2023, and April 9, 2025.
Order e book depth is measured as the typical amount of securities posted for buy or sale at one of the best bid and supply costs. Decrease depth implies worse liquidity. This metric additionally factors to comparatively poor liquidity in April 2025, when out there depth declined to the bottom ranges since March 2023 (see chart under). Depth shortly recovered and by late summer time 2025 was at ranges much like, if not higher than, any time because the Fed’s post-COVID tightening cycle began in March 2022. Depth continued trending increased via February 2026.
Order Guide Depth Elevated Steadily after April 2025 Decline

Information are for order e book depth on the inside tier, averaged throughout the bid and supply sides. Depth is measured in hundreds of thousands of U.S. {dollars} par and plotted on a logarithmic scale. Drop strains flag the low factors within the five-day transferring common for the ten-year word, that are centered round March 16, 2020, March 15, 2023, and April 9, 2025.
Measures of the worth affect of trades additionally recommend a pointy deterioration of liquidity in April 2025, a fast rebound, and regular enchancment thereafter. The following chart plots the estimated worth affect per $100 million in internet order circulate (outlined as buyer-initiated buying and selling quantity much less seller-initiated buying and selling quantity). A better worth affect suggests diminished liquidity. Worth affect rose abruptly on April 2, however then shortly reverted. By early 2026, worth affect had turn into as little as at any time since 2021.
Worth Influence Trended Down after April 2025 Improve
Notes: The chart plots five-day transferring averages of slope coefficients from each day regressions of one-minute worth modifications on one-minute internet order circulate (buyer-initiated buying and selling quantity much less seller-initiated buying and selling quantity) for the on-the-run two-, five-, and ten-year notes within the interdealer market from January 2, 2020 to February 27, 2026.

Summing Up
Treasury market liquidity over the previous yr was marked by a sudden however temporary worsening after the April 2, 2025 tariff announcement, adopted by fast enchancment when the proposed tariffs had been partially rolled again. Liquidity steadily improved thereafter, reaching its greatest degree since 2021 in early 2026. Financial uncertainty and rate of interest volatility have elevated because the finish of our pattern interval—given the battle with Iran and its repercussions—underlining the view that Treasury market liquidity warrants continued shut watching.
