Fixed Income Investing Investment Principles

Price transparency plays a central role in promoting fairness and efficiency in US capital markets. Despite recognizing this, US regulators recently reversed course on a measure to enhance transparency in the bond market.


TRACE: The Gold Standard

Three years ago, we celebrated the 20th anniversary of TRACE—the Trade Reporting and Compliance Engine (TRACE). Launched in 2002 by the Financial Industry Regulatory Authority (FINRA), TRACE was a game changer for US bond market price transparency. With its launch, the fixed income space finally had near-real-time price dissemination. Over-the-counter transactions in eligible fixed income securities are required to be reported to TRACE within 15 minutes of execution, and much of this information is then made public. For market participants, this has generally resulted in lower trading costs and narrower bid-ask spreads.1 Without this transparency in the bond market, transacting across the bond market would likely be costlier.

In our view, TRACE is the gold standard when it comes to bond market transparency. Indeed, both the UK and the European Union are currently in the process of setting up their own versions of TRACE—called the consolidated tapes—with the aim of enhancing post-trade transparency in the UK and EU bond markets.


Slow and Steady Improvements

While we believe TRACE has set the global standard for bond market transparency, there is still room for improvement—some information collected by TRACE is not made publicly available, and there continues to be a delay between when a trade is executed and when information about that trade is publicly disseminated. Dimensional has advocated for incremental improvements on both fronts—in our view, complete and immediate post-trade dissemination for all trades in fixed income securities should be the goal of any transparency regime. Over time, we have seen some of these advocacy efforts pay off. In 2022, for example, FINRA adopted amendments requiring firms to report transactions in US dollar-denominated foreign sovereign debt.2 We publicly supported this change and other similar regulatory developments.


A Pause on Progress

In 2022 FINRA proposed another enhancement to TRACE—shortening the reporting time frame for eligible securities from 15 minutes to one minute.3 We supported this proposal because shortening the time between trade execution and public price dissemination would enhance transparency and reduce information asymmetries in the fixed income market. The rule change was approved in September 2024, but just nine months later, FINRA abruptly reversed course. Instead of moving forward with the shortened time frame, FINRA proposed maintaining the existing 15-minute reporting time frame, and this rule change was approved in September 2025.4

To Dimensional, returning to the reporting time frame status quo is an unfortunate setback for bond market investors. FINRA has left the door open for future improvements to TRACE—stating that it will continue to engage with its members and monitor and study developments in the market5—and we will continue to advocate for greater transparency in the bond market.
