Remarks by Craig Phillips, Counselor to the Secretary, on Market
Structure
December 3, 2018

As prepared for delivery at The Evolving Structure of the U.S. Treasury Market: Fourth Annual
Conference
View the slide deck
Good a ernoon. I trust that all of you have found today’s panels and speakers both informative
and thought-provoking. Before I begin my remarks, I want to thank the Federal Reserve Bank of
New York for co-hosting this event on the evolving structure of the U.S. Treasury Market and also
thank the other members of the Interagency Working Group for Treasury Market Surveillance
(IAWG), for their participation here today, including the Board of Governors of the Federal
Reserve System (Federal Reserve Board), the Securities and Exchange Commission (SEC) and
the Commodity Futures Trading Commission (CFTC). Now in its 4th year, this has become an
excellent forum to discuss important issues facing the U.S. Treasury market among the o icial
and private sector.
Today I will focus on Treasury securities transaction data collected by the Financial Industry
Regulatory Authority (FINRA) through its Trade Reporting and Compliance Engine (TRACE) from
FINRA’s member broker-dealers. I will discuss Treasury’s observations from the TRACE data to
date, its significance for Treasury as issuer, as well as for the regulatory community as a whole.
Next, I will review suggestions for improvements in the data in order to incorporate unique
aspects of Treasury market trading, including elements of completeness of the Treasury
securities data set. I would then like to share some observations from our outreach e orts
before concluding with important steps concerning developing and executing a policy on the
potential for public dissemination of the data.
A er last year’s event, Treasury undertook extensive outreach to market participants that
resulted in highly productive and informative conversations, and I want to personally thank
many of you and your institutions for your participation in that e ort.

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

In short, we continue to examine the appropriate level of public dissemination for the TRACE
Treasury data at this time. As we’ve continually stated, the consideration of a properly tailored
and calibrated process for public dissemination of some form of the data is worthy of further
study. No matter the eventual outcome in this regard, it is important to continue to customize
the data for the Treasury market to make it clear and understandable; to ensure Treasury
market coverage is complete; and to collaborate within the o icial sector to gain a keen
understanding of the impact that public dissemination would have on market structure,
liquidity, and other important market factors.
The suggestions I will make for data improvements are specific to the Treasury securities market
data, and are a natural step a er adding this new, and unique asset class to the TRACE data. As
expected, TRACE has proven a highly e icient way to collect this data, and as with other asset
classes added to TRACE such as mortgage backed securities (MBS), additional improvements
are now warranted to better fit the collection to the structure of the Treasury securities market.
At the same time, I want to emphasize the tremendous importance of the TRACE Treasury
securities data and our commitment to continue to work with FINRA and the IAWG for the
ongoing improvement of the Treasury securities data. There is no question that the decision to
move down the path of collecting this data for the largest and most liquid market in the world
was critically important. We are pleased with the results to date and foresee further progress in
the future to optimize the value of the TRACE data that Treasury and our IAWG colleagues are
receiving.

HIGH LEVEL PRINCIPLES
It is useful to review a few principles that we have adopted as a framework in evaluating the
TRACE data and its usefulness to all stakeholders. Treasury is dedicated to strong market
functioning to ensure that the Treasury market remains the deepest and most liquid market in
the world. Fostering an e icient and liquid Treasury market supports Treasury’s primary
objective to fund the U.S. Government at least cost to the taxpayer over time and we believe the
data should be used in ways that are consistent with this objective by enhancing liquidity in the
Treasury market. Minimizing our own debt service costs may also contribute to lower
benchmark rates for other instruments, like corporates, agencies, and mortgages, providing cost
benefits to all borrowers. In addition, a robust and liquid Treasury market reduces frictions and
provides significant benefits for market participants that use Treasury securities for hedging or
as collateral.

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

At the outset of this process we stated that our guiding principle was to “do no harm” to the
market, and our deliberate approach in determining a path forward on TRACE data is a product
of that principle. Our second principle is to consider the interests of all of our investors in order
to encourage the broadest possible investor base for Treasury securities. Finally, Treasury is
committed to using the data to help inform policies with the potential to improve Treasury
market structure and foster innovation, while maintaining the Treasury market’s robustness and
stability.
These principles remain intact today and, in fact, the wisdom of following them has consistently
been reinforced through our discussions with a broad range of market participants. They will
continue to guide our work going forward.

WHAT TREASURY HAS LEARNED FROM THE TRACE DATA
Slide 2 – Security Volumes by Venue
This slide will look familiar to many of you who attended last year’s conference. It provides an
updated assessment of transaction volumes across the di erent segments of the market,
loosely defined as the dealer to customer (DtC) or a iliate market, the dealer to dealer (DtD)
market and the interdealer broker (IDB) market, which is further divided into an estimate of
electronic and voice IDB. As you can see, average daily transaction volumes are almost $600
billion per day. This total is largely split between the DtC and IDB markets, with primary dealers
being the dominant liquidity provider in the former, while principal trading firms (PTFs) appear
to be a substantial additional source of trading volumes in the latter electronic market, though
they are not yet identified in the data. Across the sample period, we also see a number of
regular spikes due to various events such as month-end rebalancing by market participants.

Slide 3 – Trade Sizes for Nominal Coupons
This slide shows summary statistics of the distribution of trade sizes for nominal coupon
securities reported so far. The first thing to notice is the median trade size for most coupon
securities is $1 to 5 million, a point we’ll revisit a few slides later.
Focusing on the orange and green dots gives us a view into the upper tail of trade sizes. Two
points come to mind: first, there are a number of large trades, think $20 million and above, that
occur every day across the coupon stack; second, the patterns are remarkably similar by tenor,

3/19/2020

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

though the 10- and 30-year are traded in somewhat smaller sizes due to their higher duration.
As nominal coupon securities are commonly viewed as the most liquid Treasury securities, let’s
look at how the trade sizes for other security types compare.

Slide 4 – Trade Sizes for Other Treasury Securities
Slide 4 presents the same exercise, but by security type across the top rather than by tenor.
While it may not be immediately obvious, the major di erence between these trade sizes and
those for nominal coupon securities is the pattern across on- and o -the-runs. In the previous
slide, we saw that the trade sizes for each tenor’s on-the-run security were quite compressed
within $20 million or less for even the 90th percentile, while the o -the-run trade sizes were
o en significantly larger, especially in the first, second, and third o -the-runs. In contrast, for
bills, FRNs, TIPS and STRIPS the trade sizes don’t show such a clear pattern. This lack of a
consistent pattern reflects the bilateral and idiosyncratic nature of these markets relative to the
electronic central limit order book (CLOB) transaction model that accounts for much of the
transaction volumes in on-the-run nominal coupons.

Slide 5 – Trade Size Distributions for Nominal Coupons
Rounding out this discussion, we wanted to show the variance in trade sizes by venue. On the
le side, we present the cumulative distribution of trade sizes, which increases from le to right,
for the DtC market. On the right side, we have the same chart for the IDB segment of the market.
IDB transactions are dominated by $1 million trades, whereas the DtC market has a wider range
of trade sizes, as shown on the charts. This reflects the di erent nature of the IDB vs DtC market,
with the IDB market featuring a very large number of electronic, algorithmic trades in $1 million
lots, while the DtC market features both smaller retail and larger institutional trades, which are
absorbed by dealers and then redistributed across the IDB market or their customer base.

Slide 6 – Price Dispersion DtC Nominal Coupons
This slide covers price dispersion in the DtC market. Here we introduce the notion of “excess
ticks,” which we define as the di erence between a transacted price and the relevant
benchmark bid or ask price for a given security tenor, expressed in 32nds. The data shown
reflects all TRACE trades during U.S. market hours where trade size is equal to or greater than $1
million, excluding trades that are when-issued, with a iliates, or have a trade modifier, such as
the .S flag. Positive values indicate trades at prices outside the typical bid-ask spread, negative

4/10

3/19/2020

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

values are trades within the spread. This chart shows the 10th and 90th percentiles for excess
ticks by original security term and age in increasing order of maturity from le to right. As the
chart demonstrates, price dispersion measured by “excess ticks” is quite low, on average, across
these dimensions. In particular, the median “excess tick” is negative, meaning that the median
trade occurs within the bid-ask spread. For more seasoned securities (the 1st through the 3rd
o -the-runs), we see that price dispersion is still quite low, with the entire inter-percentile range
under half a tick for securities other than the long bond. The larger inter-percentile ranges in the
longer-dated 1st through 3rd o -the-runs is related in part to larger bid-ask spreads on those
longer duration instruments.
We have excluded most seasoned securities, those that are four or more times o -the-run
because of the heterogeneity, such as high coupons versus low coupons, across the securities in
these particular tranches. That said, our preliminary analysis of that data suggest similar
patterns to the near o -the-runs, though with slightly larger tails.
These results are consistent with the notion that the Treasury securities market is already quite
transparent, something many market participants conveyed to us. While we were pleased with
the results of our initial analysis, it required significant cleaning of the data, and as such, is
worthy of further study and review.
So, to summarize, what are the major takeaways from the data? First, trading volumes and
pricing in both on-the-run and o -the-run securities are robust. On the whole, there is little
indication of illiquidity (even in o -the-runs), and the vast majority of bid-ask spreads are quite
tight. Second, as issuer, Treasury experiences tremendous continuity between secondary
trading levels and the primary auction process. This is true in both continuity of pricing but also
the participation of the primary dealers. Finally, the market structure is well functioning.
Patterns of flows, su iciency of trading venues, and the ongoing importance of DtC trading
relationships are all sound. The activities of PTFs are notable in size, a topic that I will cover in a
moment, but are working on a sustainable and predictable basis.

TRACE TREASURY SECURITIES DATA AND AREAS FOR
FOCUS AND IMPROVEMENT
FINRA has undertaken significant e orts to collect TRACE data, and its broker-dealer members
have made significant e orts to assist. Both should be commended for the work and e ort put
into this process.

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

Trade reporting of Treasury securities transactions is a tremendously large data set – typically
composed of in excess of 230,000 reported transactions daily. Due to the complex nature of the
Treasury market structure and the increased presence of electronic trading, trading volumes are
far above what has been observed in other TRACE-reported segments. This is due in part to
single economic trades being reported in multiple legs in many cases as well as the trend in
decreasing trade size due to the nature of PTF trading patterns on IDB platforms.
We believe that unique aspects of the Treasury securities market warrant continued
enhancements to the existing TRACE data reporting structure to more accurately reflect
Treasury transaction pricing and volumes, some of which have already been addressed by
FINRA, others of which are ongoing. For example, some broker-dealer firms report as two or
more members separately due to historic organizational structure. Likewise, at this initial stage,
FINRA only requires reporting Treasury security transactions to TRACE by end of day, leading to
a variety of reporting times, with many firms reporting within 15 minutes.
Having said that, let me unpack some areas we have identified as priorities for improvement in
the quality of TRACE data for Treasury securities transactions:
The granularity of timestamps need to be refined due to characteristics of the Treasury
market, such as the high frequency nature of electronic trades and the workup. There is a
wide range of protocols across reporters and some questions concerning the timestamp
methodology employed, including the level of precision;
Fees are included as part of some prices. For Treasury security trades, these fee add-ons
need to be normalized to have meaningful pricing information and trade matching;
A wide range of o -market trades are included in the data. Some relate to trades with
a iliates – an area that needs further review and standardization. Package transactions that
incorporate spread trades, for instance, are booked against a “box spread” rather than the
current “market price.” There appear to be some data reporting inconsistencies that suggest
the need for additional checks and further clarification to reporters to standardize the
reporting; and
Accurately matching trades can be challenging, which is critical to properly size the market.
This di iculty is compounded by some of the factors cited above.
Completeness of the data set is also critical. At this time there are two primary areas that can be
improved. First, the trading activity of some depository institutions that conduct a government
securities business are not reported to TRACE. There are at least three significant trading
operations that we know of that fall in this category. As mentioned by Governor Brainard earlier

3/19/2020

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

today, the Federal Reserve Board is proceeding with a plan to request this reporting to TRACE,
for both Treasury securities and agency MBS securities, which is a critical step to help complete
the data collected by FINRA for these markets.
Second, many PTFs do not report their activity to TRACE because they are not required to be
registered with the SEC as broker-dealers and become FINRA members. Beginning in April 2019,
large trading platforms operated by FINRA member broker-dealers that facilitate transactions in
Treasury securities will be required to identify customers in their reports of Treasury securities
transactions to TRACE. Because most PTF activity occurs on electronic IDB platforms, this may
capture a large segment of PTF trading volume. The volumes currently are reported by IDB
counterparties but can’t be segmented at the firm level. Of course, firm specific names and
flows would not be publicly disseminated, but the nature of this information is critical for
Treasury and regulators to have a more complete picture of market flows at any given point in
time.
Also beginning in April 2019 our ability to accurately sequence transactions, and therefore
understand the dynamics of the workup, will improve significantly as ATS will be required to
disaggregate trades executed within workups. Both these e orts were made possible with the
support of SEC and FINRA sta s.
While much work has been completed, we can and must do more. The successful completion of
this work, we believe, is and should be a condition precedent to any possible public
dissemination of the data. FINRA has been an enthusiastic partner to that end and we
appreciate the support of the Federal Reserve Board and the SEC.

SUMMARY OF TREASURY’S OUTREACH EFFORTS
So far I have been focusing on what we learned from analyzing the data. Since my
announcement at this conference last year, we have also undertaken a comprehensive outreach
e ort related to the TRACE data and the Treasury market structure more broadly, which I want
to discuss next. First, a little bit about our process and how it was guided by our principle to
consider all investor types to help ensure the broadest possible investor base. In all, we met
with each primary dealer, every major platform, many major non-dealer liquidity providers,
asset managers large and small, hedge funds, pension funds, insurers, foreign central banks and
reserve managers and anyone else who volunteered their time and insight. Once again, many
thanks to each and every one of you who gave us feedback throughout this process.

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

We were impressed by the depth and spectrum of views among market participants about the
costs and benefits of public dissemination of the TRACE data. Beginning with the general points,
market participants broadly agreed that Treasury securities prices are remarkably transparent,
particularly when compared with other fixed income markets. However, flow transparency,
especially in seasoned securities, remains more limited. This contrast brings to mind the most
o en articulated central concern of market participants regarding public dissemination of
Treasury securities transaction level data, which is that the real value to the market is the flow
transparency and that disclosing flows shortly a er they occur could have adverse impacts on
liquidity as intermediaries attempt to protect themselves by either widening out bid-ask
spreads or reducing the size of trading activity they are willing to do with counterparties.
Beginning first with on-the-run Treasury securities, we heard broadly that both price and
volume transparency is readily available through proprietary data feeds of IDB activity, while
transparency of volumes is more limited in the DtC market. Despite the information
asymmetries that currently exist in the on-the-run market, most of those we spoke to agreed
that providing greater insight into the DtC market for on-the-runs would not adversely a ect
liquidity provision. However, some expressed concern that increased transparency into
customer order flow in on-the-runs could adversely a ect liquidity in both the primary and
secondary Treasury securities markets, which clearly is a concern we take very seriously. There
is also the general concern about whether greater price and volume transparency in the DtC
market would catalyze a transition of the market from the current principal trading model into
an agency model and what that would mean for the primary dealers’ obligation to bid in all
Treasury securities auctions.
When we shi ed to o -the-runs or security types other than nominal coupons, opinions about
whether or not to publicly disseminate transaction data were far more varied. The high level
dynamics of these markets are widely known by market participants, mainly that these markets
are dealer-intermediated wherein dealers are expected to and do absorb the risks of their
customers’ trading flows. For many of the people we spoke to, the current model works quite
well because customers are able to get in and out of large positions through their dealer
counterparties, who are then able to transfer this risk while minimizing the impact on prices.
However, others noted that increased transparency in these markets might improve pricing
e iciency for all participants, enable more e ective transaction costs analysis, entice new
liquidity providers, or reduce market segmentation.

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

In consideration of these important market di erences, we thought it was helpful to frame the
question as what would an ideal reporting regime look like if we decided to adopt a policy for
data dissemination. Many of the answers we received recommended a model based on the
current TRACE dissemination models for other fixed income markets. Many market participants
endorsed publicly disseminating full volumes of Treasury securities TRACE data (anonymized)
with a significant delay, with significant meaning anywhere from 1- to 12-months, as the data
could then be used for trade cost analysis and other post-trade analytical purposes. However,
some cautioned that such a full set of data, even with significant time lags, could be analyzed
for price signals regarding flows, particularly in o -the-run securities. More real-time reporting
generated greater concern and raised important questions about capping the size of the data
disseminated.
In dimensioning the appropriate capped trade size, market participants employed their own
data, data from trading platforms, and their experience as a guide. Further complicating the
question of the optimal reporting regime, is whether or not to vary either caps or delays across
Treasury security types owing to di erent market characteristics. On this question, simplicity
rather than complexity was generally seen as more beneficial among those we spoke with,
though it was also acknowledged that nominal caps may overlook significant di erences in
duration exposure.
If we were to summarize all of this feedback into a short list of the costs and benefits of public
dissemination, it would go as follows. On the benefits side, the data could reveal greater market
depth, it could result in more competitive and homogenous pricing or it could improve end
users confidence that the prices they receive reflect best execution in the market. As for the
potential costs, public dissemination may reduce liquidity provision for larger trades and less
liquid products by intermediaries concerned that other market participants will take advantage
of the TRACE reporting a er large orders. Most importantly, markets are complex and we must
acknowledge that we lack perfect foresight into what all the unintended e ects of a policy of
public dissemination could be.

Slide 7 – Policy for the Public Dissemination of TRACE Data
In conclusion, improvements to the data and submission process, conforming standards among
submitters, improving data quality control, and assuring we have a complete data set are all
necessary in order to responsibly develop a policy on TRACE Treasury securities data
dissemination. We plan to continue to work towards resolving the data quality issues. Prior to

Remarks by Craig Phillips, Counselor to the Secretary, on Market Structure | U.S. Department of the Treasury

considering a policy decision regarding the dissemination of transaction level TRACE data, we
could consider a cross-section of volume data by security type and transaction venue in
aggregated form. This will be one of many layers of possible dissemination that we will consider,
prior to deciding whether to release trade level data, to promote increased transparency and
market knowledge and awareness, while following our principle to do no harm to the market,
which requires a cautious approach.

CONCLUSION
Over the past year and a half, we’ve gained tremendous insight into the structure of the Treasury
market as a result of receiving TRACE data on Treasury securities transactions. As the deepest
and most liquid market in the world, prices for Treasury securities are remarkably transparent
around the clock. Meanwhile, precise volume data are not available for all securities at the same
level of granularity. Therefore, many of our investors agreed that a policy of publicly
disseminating some form of the data to improve volume transparency could enhance secondary
market liquidity. However, we also recognize the uniqueness of the Treasury securities market
and that the ability of our investors to transact in meaningful size is a critical feature of the
market. Therefore, we plan to work towards first fixing the data issues and making the data
more complete before considering a policy to disseminate TRACE data. We intend to further
improve and analyze the TRACE data as we consider potential options for a policy for
dissemination, in particular related to the accuracy of trade prices.
We promise to keep all of you apprised on our progress and we would welcome any feedback at
this time. Once again, thank you to the Federal Reserve Bank of New York for hosting this event
and to the other IAWG members for their contributions to another successful conference. I’m
happy to take any questions or comments at this time.
