# Henry Dyer and Michael J. Fleming report in Liberty Street Economics on Treasury market liquidity

[Canonical reading](https://escapemeridian.com/readings/henry-dyer-and-michael-j-fleming-report-in-liberty-street-de345343)

Published April 2, 2026, Henry Dyer and Michael J. Fleming report that U.S. Treasury market liquidity worsened sharply after the April 2, 2025 tariff announcement, then improved quickly when tariff increases were partially rolled back. They assess liquidity through bid-ask spreads, order book depth and price impact, using high-frequency data from the interdealer market. Their measures show a brief deterioration followed by improvement; liquidity reached its best level since 2021 in early 2026. The authors explain why liquidity matters: the Treasury market finances the U.S. government, supports Federal Reserve monetary policy, and helps financial institutions manage interest rate risk and value other securities. They conclude that liquidity warrants continued close watching as economic uncertainty and interest rate volatility have increased since the end of their sample period. The analysis ends with the last trading day of February 2026 and does not reflect effects from the conflict with Iran.

Publication: d1a8b33c-e18d-3ab6-7969-b01c6db0d527

attribution — pass: The reading correctly attributes the post to Henry Dyer and Michael J. Fleming, published in the New York Fed's Liberty Street Economics. Its findings are framed as the authors' reports and conclusions. The text is a single analytical post, not a listing.

> Henry Dyer and Michael J. Fleming, “Treasury Market Liquidity Since April 2025,” Federal Reserve Bank of New York Liberty Street Economics

summary — uncertain: The summary faithfully reflects the post's arc and caveats. However, its central terms go unexplained and the definitions list is empty: liquidity, bid-ask spread, order book depth, price impact, interdealer market and high-frequency data. A non-specialist reader cannot tell what a liquidity worsening means in practice. Smallest repair: add the source's own plain definition of liquidity, quoted here, and one-line glosses or term-library tooltips for the three measures. The question is a fair, open issue.

> We define market liquidity as the cost of quickly converting an asset into cash (or vice versa).

date — pass: The stated publication date of April 2, 2026 matches originalPublished and the page dateline. The reading presents nothing later as part of the original and makes no forecast. The Iran reference is integrated into the body and concerns events before publication, so it reads as original even though the page was modified on April 17. The source is a publisher page, so no archive disclosure is needed.

> April 2, 2026
Treasury Market Liquidity Since April 2025

support — pass: Each claim matches its quoted text: the worsening and quick improvement, the three measures from interdealer data, the uses of the Treasury market, the best level since 2021, the continued-watching conclusion, and the sample ending in February 2026. The cited passages form the core body of the post, not apparent later additions, despite the April 17 modification. The scope limitation is accurate.

> Treasury market liquidity warrants continued close watching

media — pass: No media was selected and no verified candidates were supplied, so no media identity or relevance issue arises.
