As we navigate through 2024, there are significant and promising improvements in the Treasury market’s liquidity trends. The landscape is evolving with increased trading volumes and enhanced market depth, suggesting a cautiously optimistic outlook for the year ahead. Let’s delve into the key developments that are shaping this positive narrative.

Rising Trading Volumes and Turnover

One of the standout indicators of improved liquidity is the rise in Treasury trading volumes. In 2024, the daily average trading volume has surged to $817 billion, marking a 30% increase from 2023. This uptrend is a welcome change after a prolonged period of decline over the past decade. Notably, the 3- to 5-year sector has recorded the highest trading volumes, followed by Treasury bills (T-bills). In contrast, the long-end volumes, particularly in the 20+ year sector, have nearly tripled those in the 10- to 20-year sector.

While turnover has seen modest gains, it remains relatively low, indicating a stabilization phase following years of decline. This low turnover could be attributed to a cautious approach among investors as they adjust to the evolving market conditions.

Improved Market Depth with Room for Growth

Market depth, a critical measure of liquidity, has been on an upward trajectory since early 2022. However, it still lingers at 50% below its decade-long average. The improvement in depth is closely tied to declining volatility, which, despite still being above pre-COVID levels, has decreased from its historic highs. This depth improvement is uneven across the curve, with the front end lagging behind the long end.

Decreasing Price Impact and Stable Trading Conditions

The price impact of trades, which spiked during the pandemic, has now receded to levels comparable to those observed in 2016. This decline signifies a smaller footprint for each trade, reflecting a healthier market environment. High-frequency traders continue to provide a stable share of market depth, especially in the 10-year sector, where their presence has remained steady at around 75% for the past three years. In contrast, the long end has seen more variability, influenced by events like the UK’s liability-driven investment (LDI) deleveraging and increased Treasury auction sizes.

Challenges in Market Dispersion and Curve Metrics

The root mean square error (RMSE) of the par curve has risen to two-year highs, signaling increased dispersion. Traditionally, such dispersion hints at deteriorating liquidity in off-the-run Treasuries and potential deleveraging. While the dispersion is more pronounced at the front end, there is a belief that this increase is overstated and reflects the outsized influence of a few illiquid and deep-off-the-run bonds, particularly those issued more than 20 years ago.

Inventories and TIPS Trading Dynamics

Primary dealer inventories have surpassed their pandemic peaks, now standing nearly two standard deviations above the five-year average. However, these inventories as a share of total marketable debt remain below levels seen before the Global Financial Crisis (GFC). This rise in inventories indicates a cautious but prepared stance among dealers, anticipating potential shifts in market dynamics.

Trading in Treasury Inflation-Protected Securities (TIPS) has also shown resilience. Daily trading volumes for TIPS have averaged $18.5 billion year-to-date, in line with recent years, though they remain just above 1% of the total holdings when excluding Federal Reserve assets. Although TIPS volumes have declined from their post-COVID peaks, they are still elevated on a historical basis. TRACE data further highlights that TIPS trading volumes are highly cyclical, often spiking at month-end, during CPI release days, and on auction days.

A Healthier Market with Cautious Optimism

In summary, Treasury market liquidity has markedly improved in 2024. The combination of rising trading volumes, enhanced market depth, reduced price impact, and moderate dispersion paints a picture of a relatively healthy market, albeit not as robust as pre-pandemic conditions. Elevated dealer balance sheets remain a crucial factor to monitor, given their significant impact during previous market disruptions.

As we move forward, the continued monitoring of these liquidity metrics will be essential in understanding the evolving dynamics of the Treasury market and preparing for any potential shifts in the financial landscape.
