Subject: Petition - File No. 4-842
From: A Concerned Retail Investor




Dear Ms. Countryman,

As a retail investor, I respectfully submit this petition for
rulemaking pursuant to ~Rule 192~ of the Securities and Exchange
Commission’s (“SEC”) Rules of Practice [1], to request that the SEC
amend Rules 18 and 22 of ~National Securities Clearing Corporation
(“NSCC”) Rules & Procedures~ [2] to provide investors with clarity and
certainty regarding settlement of guaranteed transactions, strengthen
the resilience of a registered Clearing agency (e.g., the NSCC) for
their role as a central counterparty (CCP), and support the stability
of our financial markets and financial system by incentivizing
appropriate risk management practices by market participants.

I respectfully submit this petition consistent with the SEC’s website
for ~Petitions for Rulemaking Submitted to the SEC~ [3] which states
“[a]ny person may request that the Commission issue, amend or repeal a
rule of general application” where “[p]etitions must be filed with the
Secretary of the Commission” and “[p]etitions may be submitted via
electronic mail to Secretarys-Office@SEC.GOV (preferred method)”.
This petition also satisfies requirements that “[p]etitions must
contain the text or substance of any proposed rule or amendment or
specify the rule or portion of a rule requested to be repealed” and
“petitions must also include a statement of their interest and/or
reasons for requesting Commission action.” [Id.]

Background

It has come to the attention of retail investors, like myself, that
NSCC Rules and Procedures do not codify strict procedures for closing
out positions (e.g., in the event of a Member default).  Per ~NSCC’s
Disclosure Framework for Covered Clearing Agencies and Financial
Market Infrastructures~, “[a]s a cash market CCP, if a Member
defaults, NSCC will need to complete settlement of guaranteed
transactions on the failing Member’s behalf” [4 “Liquidity risk
management framework”].  However, NSCC Rule 18 SEC. 6(a) contains a
provision that “if, in the opinion of the Corporation, the close out
of a position in a specific security would create a disorderly market
in that security, then the completion of such close-out shall be in
the discretion of the Corporation”.

Retail investors like myself are concerned about potential market
distortion and market manipulation arising from the discretion
afforded to the NSCC based solely on the NSCC’s unreviewed and private
opinion regarding the [in-]completion of a close-out of a position in
a specific security that could distort markets and/or create
disorderly markets.  A few questions must be considered:

What is the underlying root cause of the disorderly market?

How can this lead to market distortions and/or manipulation?

Who is responsible for the costs of closing out a position which would
create a disorderly market?

How do we fix this?

1. What is the underlying root cause?

The answer to this first question can be found by starting from NSCC
Rule 18 where the cause of a disorderly market is a Member building up
a position that would create a disorderly market if closed out.
Members with increasingly disruptive positions eventually become de
facto Too Big To Fail as their failure would create a sufficiently
disorderly market for one (or more) securities that could pose
systemic risks to our financial system.  [5]

Thus as a Member’s risk of default increases, the Member is perversely
incentivized to increase the risk the Member poses to the financial
system by building up more positions that would be disorderly to close
in order to ensure a bail-in or bail-out to socialize losses amongst
investors and taxpayers (again) [6].  If and when a Member defaults,
any associated risks and costs are covered by CCPs, including the NSCC
and Options Clearing Corporation (“OCC”) which maintain settlement
guarantees [7].

As a Systemically Important Financial Market Utility (SIFMU)
designated CCP, the NSCC “provides clearing, settlement, risk
management, central counterparty services and a guarantee of
completion for certain transactions for virtually all broker-to-broker
trades involving equities, corporate and municipal debt, American
depositary receipts, exchange-traded funds, and unit investment
trusts” [8].  When a “Too Big To Fail” Member privatizes profits
without sufficient risk management, risks and costs of a Member
failure are socialized through CCPs which maintain guarantees on
settlement and transactions, including the NSCC which has rules,
regulations, and procedures attempting to maintain financial market
stability.

The current regulatory framework significantly handicaps CCPs,
including the NSCC, in their ability to maintain financial market
stability.  Certain Members may privatize profits and socialize losses
by building large high risk portfolios yielding short term profits for
their executives where the Member’s failure would create a disorderly
market and systemic risk allowing the Members to take the financial
system hostage for a bailout.  It is effectively impossible for CCPs
to maintain financial market stability against Members incentivized to
build up positions that would be disorderly for a CCP to close out.

2. How can this lead to market distortions and market manipulation?

Misaligned incentives.  ~Adam Smith’s invisible hand~ explains why
Members will follow incentives to build positions that would create a
disorderly market if closed out because these positions are profitable
for them and costly to others.  As a result, a build up of these
positions have been and continue to result in market distortions and
market manipulation.  As an example, a naked short position [9] in a
security held by a Member that is not closed out due to a fear of
creating a disorderly market naturally distorts the market by
increasing the amount of that security in circulation.  In economic
terms, the supply of the security has increased as a result of a naked
short transaction where a delay or failure to close out the naked
short position, due to fear of creating a disorderly market, secretly
perpetuates a market distortion by artificially and non-publicly [10]
inflating supply.

When CCPs become responsible for these disorder creating positions,
their goal of maintaining financial market stability (e.g., by
prioritizing price stability) prevents the CCPs from closing out
positions that may disrupt the market; which then perpetuates market
distortions as outstanding transactions are guaranteed, but not closed
out.  Obviously, SIFMU designated CCPs guaranteeing open transactions
for fear of disrupting the market poses systemic risks to our
financial system; especially as accumulating guarantees will
inevitably overwhelm the risk management capability of a CCP.

CCPs prioritizing price stability to avoid the appearance of market
distortions handicaps the CCPs abilities to maintain overall financial
market stability resulting in larger systemic risks to our financial
markets when guarantees on market disruptive positions accumulate.
This is especially problematic when our current regulatory framework
incentivizes the creation of market distortions by Members and shifts
the costs and burden for unwinding those distortions to a CCP.  In
essence, Members are incentivized to build up positions that would
create a disorderly market if closed out (e.g., significantly large
short positions) for short term profit, become Too Big To Fail when
their significant obligations pose a systemic risk, and then transfer
the costs of those obligations to a CCP upon failure.  Privatized
profits and socialized losses, again.

3. Who is responsible for the costs?

Certain financial market participant members are clearly responsible
for building costly positions which pose a threat of disrupting
markets.  For example, financial market participant members with the
aforementioned example of naked short positions face a risk of
unlimited loss.  These risks are guaranteed by a CCP in the event a
Member with this type of unlimited loss position fails.  There is no
comparable real world analogue to our financial markets which allows a
naked short sale, cashing out, and defaulting because selling
something one does not have is never tolerated, except in our
financial system where a CCP and the general public are currently
guaranteeing, and thus responsible for, closing costs.

A market in which some privatize profits while socializing losses
through bailouts (or bail-ins) is clearly unfair and must be
addressed.  The status quo can not continue especially with more
people becoming aware of the underlying systemic issues (many of which
were raised previously and remained unaddressed).  [11]

4. How do we fix this?

As popularized by the authors of ~Freakonomics~, we must identify
misaligned incentives in our regulatory framework and change our
regulatory framework to align incentives so that the invisible hand
guides financial market participants towards the desired behavior.  As
described above, certain financial market participant members profit
from risky positions which could pose a disruptive threat if closed
(e.g., naked short positions) where the costs of closing those
positions are guaranteed by a CCP.  Profit without risk is a clearly
misaligned incentive structure where those financial market
participants may compensate themselves lavishly for short term profits
while the ensuing risks and costs are later transferred to a CCP upon
default.

Fixing this misaligned incentive structure requires financial market
participants to be responsible for the costs of closing out their
positions; including clawing back compensation, if necessary, to
properly allocate costs to the responsible parties.  CCPs, including
the NSCC and OCC, have defined Loss Allocation Waterfalls [12] which
define the allocation of costs and should be amended to first allocate
costs to the responsible parties before other financial market
participants.  NSCC’s loss allocation waterfall allocates losses first
to the Defaulting Member followed by Corporate Contributions by other
Members.  [Id.] OCC’s loss allocation waterfall allocates losses first
to the margin deposits and clearing fund deposits of the suspended
firm, followed by OCC’s own pre-funded financial resources, and then
clearing fund deposits of non-defaulting firms and EDCP unvested
balance, and clearing fund assessments.  [Id.]  Neither loss
allocation waterfalls include executives of a defaulting Member; a key
oversight which allows Members to compensate their executives for
short term profits while long term risks and costs are to be
transferred to a CCP upon default and/or suspension of the Member.
Therefore, changes are proposed below to include clawing back
compensation and assets from executives of a defaulting and/or
suspended Member for reimbursing a CCP for the costs of closing out
positions that may be disruptive to the market.

In order to ensure fairness for all market participants, CCPs should
have defined procedures for completing settlement of and/or closing
out guaranteed transactions and/or positions.  Strictly defined
procedures eliminate bias, ambiguity, and discretion which avoid
potential for unfair, preferential, and/or discriminatory actions by
CCPs.  Changes are proposed below to specify strict rules on closing
out positions regardless of any disorder that may be caused.  As this
Petition proposes to include executives of a defaulting and/or
suspended Member in the loss allocation waterfalls for the costs of
closing out positions, including those which may be disruptive to the
market, Members (including their executives) are explicitly
disincentivized from attempting to shift risks and costs to a CCP
which will have strictly defined processes for closing out positions.
Using the very familiar and commonly understood “you break it, you
bought it” concept, this proposal ensures that executives of any
Member with positions that may disrupt the market when closed out are
also responsible for the costs of disrupting the market to encourage
and incentivize appropriate risk management practices.

As proposed, all executives (past or present) of a disruptive Member
are obligated to reimburse the CCP for losses up to an amount
equivalent to their preceding 5 years of compensation from the Member.
This approach ensures that (a) only the compensation received from the
disruptive Member is at risk, and (b) short, medium, and long term
risk management are encouraged by clawing back compensation from the 5
years prior to default.  Including past executives ensures that a
Member does not simply switch out the executive team so that past
executives transfer responsibility for their actions to new,
potentially innocent, executives.

Proposed Changes

Regarding the text and substance of the amendment, I request that the
NSCC modify Rules 4, 18, and 22 of the NSCC’s Rules and Procedures to
address the aforementioned issues by:

(a) codifying strict procedures for completing settlement of
guaranteed transactions,

(b) removing ambiguity and discretion,

(c) enhancing the liquidity and strengthening the resilience of
SIFMUs, particularly registered Clearing agencies such as the NSCC and
OCC,

(d) supporting the overall stability of our financial markets and
financial system, and

(e) incentivizing appropriate risk management practices of financial
market participants.

With respect to the text of the proposed changes itemized below (blue,
if available), additions are identified by square brackets (i.e., “[“
and “]”) and double-dashes (i.e., “--”) indicate deletions.

NSCC Rule 4 Proposed Change

Each Member[, including its executives,] shall be obligated to the
Corporation for the entire amount of any loss or liability incurred by
the Corporation arising out of or relating to any Defaulting Member
Event with respect to such Member. [To the extent that such loss or
liability is not satisfied by the Member, all executives of the Member
(past or present) shall be obligated to the Corporation for an amount
equivalent to the preceding 5 years of compensation from the Member.]
To the extent that such loss or liability is not satisfied pursuant to
Section 3 of this Rule 4, the Corporation shall apply a Corporate
Contribution thereto and charge the remaining amount of such loss or
liability ratably to other Members, as further provided below.

NSCC Rule 18 Proposed Change

SEC. 6. (a) Promptly after the Corporation has given notice that it
has ceased to act for the Member, and in a manner consistent with the
provisions of Section 3, the Net Close Out Position with respect to
each CNS Security shall be closed out (whether it be by buying in,
selling out or otherwise liquidating the position) by the
Corporation--; provided however, if, in the opinion of the
Corporation, the close out of a position in a specific security would
create a disorderly market in that security, then the completion of
such close-out shall be in the discretion of the Corporation--.

Final Remarks

As a retail investor, I believe these enhancements to NSCC Rules 4, 18
and 22 will protect investors; maintain fair, orderly, and efficient
markets; and facilitate capital formation in accordance with the SEC’s
mission.  Removing ambiguity and discretion by codifying strict
procedures for completing settlement of guaranteed transactions at our
CCPs ensures consistent clearance and settlement procedures are well
defined for all market participants fostering a level playing field
for everyone.  Of the two options proposed for NSCC Rule 22, Option B
“No Exceptions” is preferable to Option A in ensuring consistent
application of Rules, Procedures, and regulations issued by the CCP.
Option A is proposed with the acknowledgement that flexibility in
managing situations can be helpful, but NSCC Rule 22 would need to
mandate full disclosure to the public to avoid distorting markets as
reducing information asymmetries leads to more efficient and fair
markets.

These enhancements to NSCC Rules foster a “you broke it, you bought
it” environment where costs for closing out positions, including those
which may be disruptive, are first paid by the defaulting Member(s)
and its executives with defined and consistent application of
clearance and settlement procedures.  Including clawbacks for
executive compensation in the loss allocation waterfall introduces
another loss absorbing resource and incentivizes proactive risk
management practices over the short, medium, and long term which
simultaneously discourages socializing losses for privatized profits.
Thus, the proposed enhancements to the loss allocation waterfall
enhances the liquidity and strengthens the resilience of registered
Clearing agencies, such as the NSCC, which supports the overall
stability of our financial markets and financial system. [13]

Retail investors like myself appreciate the opportunity to submit this
petition for rulemaking and respectfully request that the Commission
act on it promptly for the NSCC with similar conforming changes for
the DTC (e.g., Rules 4 and 18), FICC Government Securities Division
(e.g., Rules 4 and 42), FICC Mortgage Backed Securities Division
(e.g., Rules 4 and 33), and elsewhere as applicable (e.g., Options
Clearing Corporation which describes their loss allocation waterfall
in “OCC’s Clearing Member Default Rules and Procedures” [15]).

available from the Federal Reserve Bank of NY.

[6] Decades after the Global Financial Crisis, options for resolving
large financial institutions remain limited with bail-ins potentially
replacing the unpopular bail outs.  See, e.g, Investopedia
(~https://www.investopedia.com/terms/b/bailin.asp~) and the Federal
Reserve Bank of New York’s “Why Bail-In? And How!”
(~https://www.newyorkfed.org/medialibrary/media/research/epr/2014/1412somm.pdf/1000~).
While bail-ins are theoretically more palatable with creditors
absorbing losses instead of taxpayers, self serving profit motivated
financial institutions remain committed to shifting losses to others
as exemplified by the Federal Reserve and Federal Deposit Insurance
Corporation (FDIC) which proposed to have new bond investors absorb
losses first [2022 Proposed Rule Federal Reserve Docket R-1786 RIN
7100-AG4 and FDIC RIN 3064-AF86 available on the Federal Register at
~https://www.federalregister.gov/documents/2022/10/24/2022-23003/resolution-related-resource-requirements-for-large-banking-organizations~].

which note that this strategy was successfully implemented with the

such situations” to “be fully written off in the event of a trigger
event”.

NSCC of responsibility for settlement obligations including the time
when OCC’s settlement guarantee ends and NSCC’s settlement guarantee
begins.

[8] ~https://www.dtcc.com/about/businesses-and-subsidiaries/nscc~

[9] While a naked short position is used as an example here, it is
only chosen as an example due to its inherent risk of unlimited loss.
Any type of position could become risky as an extremely large long
position could also lead to a disorderly market on close out even with
limited loss potential.  A large short position (whether naked or
borrowed) is of particular relevance as the SEC’s Staff Release
GameStop Report
[~https://www.sec.gov/page/sec-staff-release-gamestop-report~] noted
that GameStop (GME) had significant short interest (as a percent of
float) in January 2021 of 122.97% with “short interest of more than
shares outstanding in January 2021” [Id. pg 21].

[10] Per the current NSCC Rule 22, only certain parties have access to
records of any extension, waiver, or suspension of rules related to
not closing out a position.  A much smaller subset of those parties
with access are actively made aware of the situation.  One option to
mitigate market distortions would be to timely (i.e., immediately)
make the written reports of Rule 22, including the pertinent facts,
available to the SEC and to the general public as proposed for NSCC
Rule 22 as Option A - Public Notice.

[11] For example, naked shorts and failures to deliver were documented
in Dr. Susanne Trimbath’s book “Naked, Short and Greedy: Wall Street’s
Failure to Deliver” and in 2008 the SEC halted short selling of
financial stocks (and only financial stocks) in an emergency action
“to combat market manipulation” and “restore equilibrium to markets”.
[See, e.g., ~https://www.sec.gov/news/press/2008/2008-211.htm~]

[12] NSCC’s Loss Allocation Waterfall may be found in, for example,
NSCC’s Rules Rule 4 SEC 4 “Loss Allocation Waterfall, Off-the-Market
