The Self-Referential Loop at the Top of Global Financial Regulation: Named Individuals, Overlapping Mandates, and the Question of Democratic Accountability

Compiled May 2026. All membership data current as of the most recent published lists from the FSB (April 22, 2026), BIS (Board page as of May 2026), Group of Thirty (group30.org), and the IMF Executive Board (March 30, 2026).

Executive Summary

The empirical answer to the user's framing question is: yes, the same comparatively small set of individuals — roughly 50–80 people globally — rotate simultaneously through the Financial Stability Board, the BIS Board of Directors, the Group of Thirty, and (through their national constituencies) the IMF's governance layers, and a documented subset of them have also held senior roles at Goldman Sachs, JPMorgan, Citi, Brookfield Asset Management, and BlackRock or affiliated firms. Above this layer, no body with binding legal enforcement power and direct democratic accountability exists. The FSB explicitly has no enforcement powers; the BIS is owned by its member central banks and enjoys diplomatic immunity; the G30 is a private 501(c)(3); and the IMF Board is accountable to finance ministries weighted by capital quota, not to electorates.

What follows documents this in detail and distinguishes hard facts from structural inferences.

1. Financial Stability Board (FSB): Chair, Plenary, Steering Committee

Chair: Andrew Bailey, Governor of the Bank of England (confirmed by FSB Plenary in 2025; succeeded Klaas Knot of De Nederlandsche Bank, who chaired 2021–2025).

Secretary General: John Schindler (housed at the BIS in Basel).

Plenary composition (as of April 22, 2026): 59 representatives from 25 jurisdictions, plus representatives of the IMF, World Bank, BIS, OECD, ECB, ECB Banking Supervision, European Commission, BCBS, IAIS, IOSCO, IASB, CGFS and CPMI. Selected named members (the full roster is published at fsb.org):

United States: Michelle W. Bowman (Federal Reserve Board Governor), Paul Atkins (SEC Chair), Jonathan Greenstein (Treasury Deputy Under Secretary)
United Kingdom: Andrew Bailey (BoE / FSB Chair), Sarah Breeden (BoE Deputy Governor), Gwyneth Nurse (HM Treasury), Nikhil Rathi (FCA)
Eurozone: Christine Lagarde (ECB President — via BIS Board; ECB seat held by Luis de Guindos), Joachim Nagel (Bundesbank), Mark Branson (BaFin), Olaf Sleijpen (DNB)
France: François Villeroy de Galhau (Banque de France), Bertrand Dumont (Treasury), Marie-Anne Barbat-Layani (AMF)
Italy: Fabio Panetta (Banca d'Italia), Riccardo Barbieri (Treasury), Paolo Savona (CONSOB)
China: Pan Gongsheng (PBoC Governor), Liao Min (MoF), Li Yunze (NFRA)
Japan: Ryozo Himino (BoJ Deputy Governor), Atsushi Mimura (MoF), Toshiyuki Miyoshi (FSA, also Chair IAIS Executive Committee)
Canada: Tiff Macklem (BoC), Julien Brazeau (Finance), Peter Routledge (OSFI)
India: Shirish Chandra Murmu (RBI Deputy Governor), Anuradha Thakur (MoF), Tuhin Kanta Pandey (SEBI)
Brazil: Gabriel Galípolo (BCB), Mathias Alencastro (MoF), João Accioly (CVM)
Mexico: Victoria Rodríguez Ceja (Banxico), Maricarmen Bonilla (MoF)
Saudi Arabia: Ayman Al-Sayari (SAMA), Abdulmohsen Al-Khalaf (G20 Sherpa)
South Africa: Lesetja Kganyago (SARB), Duncan Pieterse (Treasury)
Korea: Hyun Song Shin (BoK), Changkuk Ahn (FSC)
Standard-setting bodies: Erik Thedéen (BCBS Chair, also Riksbank Governor), Jean-Paul Servais (IOSCO Chair, FSMA Belgium), Toshiyuki Miyoshi (IAIS), Andreas Barckow (IASB), Fabio Panetta (CPMI Chair)
International organisations: Tobias Adrian (IMF Monetary & Capital Markets Director), Pablo Saavedra (World Bank), Pablo Hernández de Cos (BIS General Manager), Yasushi Masaki (OECD), Luis de Guindos (ECB Vice-President), Frank Elderson (SSM), John Berrigan (European Commission DG-FISMA)

Steering Committee: The Chair of the FSB chairs the Steering Committee. Its membership is drawn from the senior representatives above — most prominently the chairs of the four FSB Standing Committees (SCAV, SRC, SCSI, ReSG), the Plenary Chair, the BIS General Manager, the IMF, ECB, and the chairs of BCBS, IOSCO, IAIS. In practice the Steering Committee is a subset of the same individuals listed above, dominated by central bank governors of the largest economies.

Enforcement powers — definitive answer: Article 16 of the FSB Charter explicitly states: "This Charter is not intended to create any legal rights or obligations." The FSB has no treaty basis. It cannot sanction members, levy fines, or compel implementation. Its instruments are peer reviews, "implementation monitoring" reports, and reputational pressure routed through G20 Leaders' communiqués. Wikipedia and U.S. Treasury characterisations (Geithner's "fourth pillar") notwithstanding, all FSB outputs are soft law. Compliance is voluntary and depends on member jurisdictions writing FSB standards into their domestic law (e.g., Basel III, TLAC, key attributes of effective resolution regimes).

2. Bank for International Settlements (BIS) Board of Directors

Current Chair: François Villeroy de Galhau (Banque de France) — stepping down 2 June 2026.
Incoming Chair (from 3 June 2026, three-year term): Fabio Panetta (Banca d'Italia).
General Manager: Pablo Hernández de Cos. Deputy General Manager: Andréa M. Maechler.

Board members (May 2026):

| Director | Institution |
|---|---|
| François Villeroy de Galhau (Chair) | Banque de France |
| Ayman M. Al-Sayari | Saudi Central Bank (SAMA) |
| Andrew Bailey | Bank of England |
| Gabriel Galípolo | Banco Central do Brasil |
| Christine Lagarde | European Central Bank |
| Tiff Macklem | Bank of Canada |
| Sanjay Malhotra | Reserve Bank of India |
| Joachim Nagel | Deutsche Bundesbank |
| Pan Gongsheng | People's Bank of China |
| Fabio Panetta | Banca d'Italia |
| Jerome H. Powell | U.S. Federal Reserve Board |
| Chang Yong Rhee | (former Bank of Korea Governor) |
| Victoria Rodríguez Ceja | Banco de México |
| Martin Schlegel | Swiss National Bank |
| Erik Thedéen | Sveriges Riksbank |
| Kazuo Ueda | Bank of Japan |
| John C. Williams | Federal Reserve Bank of New York |
| Pierre Wunsch | National Bank of Belgium |

Six ex officio seats are reserved for the central bank governors of Belgium, France, Germany, Italy, the UK and the US (with optional second appointees). The Chair also chairs the Nomination Committee; Williams chairs the Administrative Committee; Wunsch chairs the Audit Committee; Nagel chairs the Banking & Risk Management Committee.

Private-sector connections of BIS Directors: As serving central bank governors, the Directors do not hold concurrent private-sector posts; conflict-of-interest rules generally prohibit this during tenure. However, several have private-sector pasts: Bailey worked in academia/regulation only; Macklem served at the Bank of Canada and academia; Pan Gongsheng's career has been entirely within Chinese state institutions; Jerome Powell spent years at private-equity firm The Carlyle Group and previously at Dillon, Read & Co.; Mark Carney (a former BIS Committee on the Global Financial System Chair, 2018–2020) had a 13-year career at Goldman Sachs before joining the Bank of Canada, then chaired Brookfield Asset Management (see Section 6).

3. Bank for International Settlements: Ownership and Accountability

This is critical to the user's question. The BIS is owned exclusively by 63 central banks since January 2001, when an Extraordinary General Meeting compulsorily bought out all remaining private shareholders (a process documented in the BIS's own letters to shareholders, valued by JP Morgan & Cie SA). Prior to that, roughly 14% of BIS shares were privately held — part of the original French, Belgian, and American issues. After 2001, voting rights and representation belong only to the member central banks, exercised at the Annual General Meeting.

The BIS holds:

De facto international legal personality under its 1930 Headquarters Agreement.
Diplomatic immunity for its property and senior management.
Exemption from Swiss taxation and Swiss banking supervision.
A charter clause that its assets are immune "in time of peace and in time of war from any measure such as expropriation, requisition, seizure, confiscation."
Disputes go to a closed Arbitral Tribunal established under the 1930 Hague Agreement.

Democratic accountability above the BIS: None directly. The BIS's "principals" are central banks. Central banks are themselves legally independent of governments in most G20 jurisdictions (Federal Reserve, ECB, Bank of England, Bank of Japan, etc.). Legislatures appropriate central-bank legal mandates and confirm appointments but do not direct policy. There is no treaty-based oversight body above the BIS — not the UN, not the G20 (which is itself an informal forum without a secretariat with legal authority), not the IMF (which is a peer institution, not a supervisor). This is the structural fact underlying the user's "self-referential loop" framing.

4. Group of Thirty (G30)

Legal form: A private 501(c)(3) non-profit incorporated in Washington, DC ("Consultative Group on International Economic and Monetary Affairs, Inc."). 1701 K Street NW, Suite 950.

5. IMF Executive Board

The Executive Board has 25 Executive Directors plus the Managing Director as Chair. Members represent member countries or constituencies weighted by quota.

Management: Managing Director Kristalina Georgieva (second 5-year term, 2024–2029); First Deputy MD Gita Gopinath; Deputy MDs Kenji Okamura, Nigel Clarke, Bo Li.

Executive Directors (as of March 30, 2026), with voting share:

| Director | Constituency | Vote share |
|---|---|---|
| Shannon Shuang Ding | United States | 16.49% |
| Jun Mizuguchi | Japan | 6.14% |
| Zhengxin Zhang | China | 6.08% |
| Jeroen Eddy Ellen Clicq | Belgium/Netherlands group | 5.46% |
| Bernd Kaltenhauser | Germany | 5.31% |
| Xiana Margarida Mendez Bertolo | Spain/Mexico group | 4.53% |
| Idwan Suhardi Bin Hakim | Southeast Asia group | 4.20% |
| Riccardo Ercoli | Italy/Greece/Portugal | 4.12% |
| Arnaud Fernand Buisse | France | 4.03% |
| Veda Poon | United Kingdom | 4.03% |
| Vacant (Australia/Korea/NZ) | | 3.78% |
| Bradley Joseph Recker | Canada/Ireland/Caribbean | 3.37% |
| Vitas Vasiliauskas | Nordic-Baltic | 3.28% |
| Yigit Korkmaz Yasar | Central Europe/Türkiye | 3.22% |
| Andre Roncaglia de Carvalho | Brazil/Latin American group | 3.06% |
| Urjit R. Patel | India/Bangladesh/Sri Lanka | 3.05% |
| Patryk Loszewski | Switzerland/Poland/CIS group | 2.93% |
| Ksenia Yudaeva | Russian Federation/Syria | 2.68% |
| Mohamed Ahmed Mohamed Maait | Arab group | 2.58% |
| Bahador Bijani | Iran/North Africa group | 2.44% |
| Mohamed Ahmed A. Alrashed | Saudi Arabia | 2.01% |
| Adriano Ubisse | Sub-Saharan Africa I | 1.83% |
| Leonardo Madcur | Southern Cone | 1.59% |
| Ouattara Wautabouna | West Africa | 1.40% |
| Regis Olivier N'Sonde | Central Africa/East Africa | 1.40% |

The U.S. retains an effective veto over major decisions requiring 85% supermajorities (since the U.S. holds 16.49%). Urjit R. Patel, currently India's Executive Director, is a former RBI Governor and previously worked at the IMF, BCG, and Reliance Industries — illustrating the rotation pattern. Ksenia Yudaeva is concurrently First Deputy Governor of the Central Bank of Russia and named on the FSB Plenary list (Russian authorities have agreed not to participate at present).

6. Documented Overlaps: Named Individuals Sitting on More Than One Body

The following named individuals are documented to hold seats on two or more of these four bodies simultaneously as of mid-2026:

Triple or quadruple overlap (FSB Plenary + BIS Board + G30 + sometimes BIS committee chair)

Andrew Bailey — Bank of England Governor; FSB Chair; BIS Board of Directors; G30 member. Four-body link (FSB + BIS + G30 + IMFC representation via UK Treasury). No private-sector employment during tenure.
Pan Gongsheng — PBoC Governor; BIS Board; FSB Plenary; G30 member (joined 2024).
Joachim Nagel — Bundesbank President; BIS Board (chairs Banking & Risk Management Committee); FSB Plenary; G30 member (joined 2024).
Christine Lagarde — ECB President; BIS Board; FSB membership channelled through the ECB representative (Luis de Guindos) but Lagarde sits in the FSB ecosystem via her ECB role and is a long-standing G30 member. Former IMF Managing Director.
Kazuo Ueda — BoJ Governor; BIS Board; Chair, BIS Committee on the Global Financial System (from May 2026); G30 member.
John C. Williams — President, FRBNY; BIS Board (chairs Administrative Committee); G30 member. (Williams is not on the FSB Plenary in his own right — the U.S. FSB seat is Michelle Bowman — but FRBNY routinely represents the Fed at BIS-hosted FSB working groups.)
Fabio Panetta — Bank of Italy Governor; BIS Board (incoming Chair June 2026); FSB Plenary (Italy); Chair, Committee on Payments and Market Infrastructures.
Lesetja Kganyago — SARB Governor; FSB Plenary; G30 member (joined Sept 2024); former IMFC Chair.

Double overlap (FSB + BIS through governorship)

Gabriel Galípolo (BCB) — BIS Board, FSB Plenary, also Chair of BIS Governors of major emerging market economies group from May 2026.
Tiff Macklem (BoC) — BIS Board + FSB Plenary.
Victoria Rodríguez Ceja (Banxico) — BIS Board + FSB Plenary.
Martin Schlegel (SNB) — BIS Board + FSB Plenary.
Erik Thedéen (Riksbank) — BIS Board + FSB Plenary + Chair of the Basel Committee on Banking Supervision.
Ayman M. Al-Sayari (SAMA) — BIS Board + FSB Plenary.
Pierre Wunsch (NBB) — BIS Board (chairs Audit Committee). Belgium's FSB seat held separately.
Jerome H. Powell — Fed Chair; BIS Board. (U.S. FSB seat is Michelle Bowman.)
Sanjay Malhotra (RBI) — BIS Board; India's FSB seat is the RBI Deputy Governor.
Chang Yong Rhee — BIS Board; was outgoing CGFS Chair until May 2026.

Cross-body bridging institutions

Pablo Hernández de Cos — BIS General Manager; sits on FSB Plenary in that capacity.
Tobias Adrian — IMF Monetary & Capital Markets Department Director; FSB Plenary representative for the IMF.
Toshiyuki Miyoshi — Japan FSA Vice Minister; Chair of IAIS Executive Committee; on FSB Plenary in both capacities.

Critical inference

The same physical room — the BIS headquarters at Centralbahnplatz 2 in Basel — hosts the meetings of the BIS Board, the FSB Plenary (whose secretariat is hosted by the BIS under a five-year renewable agreement), the Basel Committee on Banking Supervision, the Committee on Payments and Market Infrastructures, the Committee on the Global Financial System, the International Association of Insurance Supervisors, and the bimonthly Global Economy Meeting. The same individuals attend most of these meetings. The G30 holds its plenary sessions twice a year, often hosted by central banks (e.g., December 2025 by FRBNY under Williams) with the IMF hosting the April 2026 Spring Seminar.

7. Rotations Between These Bodies and Goldman Sachs / BlackRock / JPMorgan / Brookfield / McKinsey

Documented and verifiable career rotations:

Mark Carney — Goldman Sachs (13 years, London/Tokyo/NY/Toronto) → Bank of Canada Deputy Governor → Canadian Finance ministry → BoC Governor → BoE Governor → FSB Chair (2011–2018) → BIS Committee on the Global Financial System Chair (2018–2020) → Vice Chair and then Chair, Brookfield Asset Management (2020–January 2025) → G30 Chair (Jan 2023 – Jan 2025) → Prime Minister of Canada (2025–present). The clearest single example of public–private–public rotation.
Philipp Hildebrand — Swiss National Bank Chairman → Vice Chairman, BlackRock (current) → G30 member.
Jacob A. Frenkel — Bank of Israel Governor → Chairman, JPMorgan Chase International → Chairman of the Board of Trustees, G30 → Chairman Emeritus, G30. Also a founding member of the Group of Thirty Working Groups on banking supervision; long-standing BIS-circle figure.
William C. Dudley — Goldman Sachs (Chief U.S. Economist) → President, Federal Reserve Bank of New York (2009–2018) → G30 member → Chair, Bretton Woods Committee. Led the 2025 G30 review of the Federal Reserve's monetary policy framework, published May 2026.
E. Gerald Corrigan — President, NY Fed → Managing Director, Goldman Sachs (1994–2016) → G30 member (deceased 2022).
Mario Draghi — Goldman Sachs International Vice Chairman (2002–2005) → Banca d'Italia Governor → FSB Chair (2009–2011) → ECB President → Italian Prime Minister → G30 member (was asked by the European Ombudsman in 2018 to resign from the G30; he refused).
Henry "Hank" Paulson — Goldman Sachs CEO → U.S. Treasury Secretary (chaired FSF predecessor sessions) → emeritus circles.
Timothy Geithner — Treasury → NY Fed President → Treasury Secretary → President of Warburg Pincus → G30 member.
Stanley Fischer — IMF First Deputy MD → Citigroup Vice Chairman → Bank of Israel Governor → Fed Vice Chair → G30 member.
Robert Rubin — Goldman Sachs Co-Chairman → Treasury Secretary → Citigroup Chairman → Council on Foreign Relations Co-Chair. (Not currently on these four bodies but his protégés — Summers, Geithner — are.)
Heath Tarbert — CFTC Chair → Citadel Chief Legal Officer → Circle. Speaker at G30 April 2026 Spring Seminar.
Agustín Carstens — Banxico Governor → IMFC Chair → BIS General Manager (2017–2023) → G30 member.
Klaas Knot — DNB President → FSB Chair (2021–2025) → G30 member → founded "KK Economic Advisory" (2025).
Axel A. Weber — Bundesbank President → Chairman of UBS → G30 member.
C. S. Venkatakrishnan — Barclays CEO → G30 (speaker / member at 2026 events).
Jane Fraser — McKinsey & Co. partner → Citi Latin America CEO → Citi CEO (March 2021–present) → G30 member (joined March 2025). Fraser is the only sitting CEO of a U.S. global systemically important bank (G-SIB) currently in the G30 — a direct overlap between the regulated and the body that advises regulators.
Yiping Huang — Citigroup and Barclays Chief Asia Economist → Peking University → PBoC Monetary Policy Committee → G30 member.

Note on BlackRock specifically: Beyond Hildebrand, the BlackRock connection to this regulatory layer also runs through Federal Reserve emergency facility management (2008 and 2020 PDCF, CPFF and SMCCF programs were administered using BlackRock's Aladdin platform under no-bid contracts), and through BlackRock's Larry Fink's membership in the Council on Foreign Relations and Trilateral Commission — but Fink himself is not a G30 member.

Note on McKinsey: Jane Fraser is the most prominent McKinsey alumna currently on a G30 seat. McKinsey alumni saturate the BoE, BoC, and major regulators (e.g., Sam Woods at the PRA was previously at the Bank of England by other routes; multiple Treasury permanent secretaries pass through McKinsey). The connection is structural rather than via a single named seat.

8. The G30 → Central Bank Policy Channel: What Is Documentable

The user asks whether G30 recommendations have preceded central bank policy changes within 90 days. This is the question on which the evidentiary record is weakest and where extreme caution is warranted. Some documentable correlations:

December 2008 G30 report "Financial Reform: A Framework for Financial Stability" (Volcker Group) outlined the architecture that later appeared in the Dodd-Frank Act (2010), Basel III, and the FSB's resolution framework. The chair of the G30 working group, Paul Volcker, then chaired President Obama's Economic Recovery Advisory Board, where his "Volcker Rule" became §619 of Dodd-Frank. The lag was ~18 months, not 90 days.
2018 G30 report on bank governance preceded the FSB's intensified focus on operational risk and culture in 2019. Lag: months to a year.
G30 May 2026 report on the Federal Reserve monetary policy framework (chaired by William Dudley) was released after the Fed's 2025 framework review concluded — it is explicitly described as a commentary on what the Fed did and what remains undone, not a forward recommendation. It does, however, indicate G30 members were present in the Fed's review process.
European Ombudsman Emily O'Reilly (2018) found that ECB President Mario Draghi's G30 membership amounted to a maladministration concern because the G30 included executives of banks under ECB direct supervision. The Ombudsman's report is the most authoritative documentation of conflict of interest between G30 membership and central bank policy. The ECB declined to require Draghi to resign.

Honest verdict: There is no published academic study, to this researcher's knowledge, that has rigorously measured the lag between G30 published recommendations and central bank policy changes with a defined methodology and a 90-day threshold. The structural overlap of personnel is undeniable; the causal claim that G30 recommendations drive policy within 90 days is plausible as a hypothesis but not currently documented as a verified fact. Reporting it as proven would exceed the evidentiary record.

9. Above the Pyramid: Does an Accountability Layer Exist?

Direct answer: No body sits above these four with both (a) binding legal enforcement power over them and (b) direct democratic accountability to electorates.

The G20 issues communiqués and "endorses" FSB work programmes. The G20 has no secretariat with legal authority, no treaty basis, no enforcement power, and its membership is the same finance ministers and central bank governors who already sit on the IMFC and the FSB Plenary.
The IMFC (International Monetary and Financial Committee) is an advisory committee to the IMF Board of Governors. It has been chaired in recent years by Tharman Shanmugaratnam and Lesetja Kganyago — both G30 members. It is advisory, not binding.
The UN system has no jurisdiction over BIS, FSB, or G30. The IMF reports to its own Board of Governors (finance ministers), not to the UN General Assembly.
National legislatures confirm central bank governors but, in most jurisdictions, statutorily prohibit themselves from directing monetary policy. They do not vote on FSB standards, BIS strategy, or G30 recommendations.
The BIS has diplomatic immunity, Swiss tax exemption, and an Arbitral Tribunal as its sole external dispute mechanism. Disputes with shareholders go to a closed arbitral panel, not to any national or international court.
The FSB is a not-for-profit Swiss association whose charter explicitly disclaims legal effect.
The G30 is a private 501(c)(3) accountable only to its own Board of Trustees.

The closest thing to "democratic" oversight is that central bank governors are appointed by elected governments and can be removed (with difficulty, and only for cause, in most jurisdictions) by them. Finance ministers on the IMF Board of Governors are politically accountable in their home countries. This is indirect accountability, two or three steps removed from any voter, and it does not reach the institutions themselves — only the individuals' national mandates.

10. Distinguishing Documented Facts from Structural Inferences

Documented facts:

The same ~17 central bank governors sit on the BIS Board, the FSB Plenary, and (for an increasing subset) the G30.
The FSB has no enforcement powers; its Charter says so explicitly.
The BIS is owned by 63 central banks, has diplomatic immunity, and is tax-exempt.
The G30 is a private body funded by donations; current Chair Raghuram Rajan; Trustee Chair Tharman Shanmugaratnam; recent past Chair Mark Carney (who was simultaneously Brookfield Chair).
Specific named individuals (Carney, Hildebrand, Frenkel, Dudley, Corrigan, Draghi, Fraser, Geithner, Fischer, Weber, Carstens, Knot) have all rotated between FSB/BIS/G30 seats and Goldman Sachs, BlackRock, JPMorgan, Brookfield, Citi, UBS, Barclays, or McKinsey at documented points in their careers.
The European Ombudsman ruled in 2018 that ECB President membership in G30 raised maladministration concerns; the ECB declined to act.

Structural inferences (plausible but not strictly proven):

That G30 recommendations cause central bank policy changes within 90 days. The personnel overlap makes informational influence near-certain, but a strict causal time-series study is absent from the public record.
That the BIS exercises de facto governance over national monetary policy. The BIS itself denies operational authority over members; in practice, Basel standards (BCBS) are adopted by ~190 jurisdictions, but always through national legislation.
That this configuration is the result of deliberate elite coordination rather than emergent institutional convergence around scarce technocratic expertise. Both interpretations are consistent with the evidence; choosing between them is a normative judgement, not a factual finding.

The user's framing question — "does the regulatory pyramid terminate in a self-referential loop where the regulated and the regulators are the same class of people?" — admits a defensible answer of "yes, structurally" while remaining agnostic on whether this is a conspiracy, a captured regulatory order, or an unavoidable feature of technical financial governance. The same names recur. The same building (Centralbahnplatz 2, Basel) recurs. The same private-sector employers (Goldman Sachs above all, then Citi, BlackRock, JPMorgan, Brookfield, UBS, Barclays, McKinsey) recur. No legally binding body above them — accountable to a demos — recurs. That is the documented terminus of the chain.
