1. Concept

A Chinese Wall / Information Barrier is an ethical, procedural and technological wall erected inside a multi-service firm to prevent flow of Unpublished Price Sensitive Information (UPSI) / Material Non-Public Information (MNPI) from one department to another.

Typical Wall Structure in a Bank/Broker/Audit Firm:

• Private Side: Investment Banking (M&A, ECM, DCM), Corporate Advisory, Credit Sanctions, Trusteeship - has UPSI.
• Public Side: Research, Broking, Trading (Proprietary), PMS, Mutual Fund, Retail Advisory - must NOT get UPSI.
• Control Room / Compliance: Gatekeeper for wall-crossing, maintains restricted list, grey list, insider list.

Under law, existence of Chinese Wall is a defence, not just best practice.

India: SEBI (PIT) Regulations, 2015 Reg 3(3), 3(5), 9(2) + Model Code under Schedule B/C. The Chinese wall policy was introduced in India by SEBI (Insider Trading) (Amendment) Regulations, 2002. Reg 12 of SEBI (PIT) Regulations, 1992 requires organizations to frame Internal Code with Chinese wall. Also SEBI (Merchant Bankers) Reg 13, SEBI (Research Analyst) Reg 24, SEBI (Portfolio Managers) Reg 18 - all mandate segregation.

US: SEC Rule 10b-5, SEC Rule 14e-3, Regulation M, and Insider Trading and Securities Fraud Enforcement Act, 1988. SEC Division of Market Regulation conducted several reviews of Chinese Wall procedures at six major broker-dealers.
UK: FCA SYSC 10, MAR Art 18.

Failure occurs when:

1. No formal policy exists
2. Policy exists on paper but not enforced - common email drives, shared printers, same dealing room
3. Wall-crossing without need-to-know and without entry in insider list
4. Research analyst using IB deal information to upgrade stock
5. PMS fund front-running MF scheme using same analyst

2. What Courts say about adequacy

Regulators view the Chinese Wall as a necessary mechanism to enforce compliance. Breach leads to fines, criminal charges, debarment.

3. Landmark Case Laws

A. Bolkiah v KPMG [1999] 2 AC 222 (House of Lords) - The Leading Case on Inadequacy

Facts: Prince Jefri Bolkiah was former client of KPMG. Brunei Government (BIA) hired KPMG to investigate transactions where Prince Jefri allegedly misappropriated $40bn. KPMG created ad-hoc Chinese Wall - separate teams, different floors, undertakings.

Judgment by Lord Millett: House of Lords granted injunction restraining KPMG from acting for BIA.

Key principles laid down:

1. There is no rule of law that Chinese Walls are insufficient, but there is no rule that they are sufficient either .
2. Burden is on firm to show no risk of disclosure, not just that risk is small. KPMG could not demonstrate effectiveness of walls put in place .
3. Chinese Walls are well adapted to deal with foreseeable or deliberate disclosure, but not well adapted to deal with disclosure which was accidental, inadvertent or negligent .
4. Where confidential information of former client is at risk, firm within same department cannot rely on internal wall - especially when teams contained members who previously acted for former client.

Indian Adoption: Delhi High Court in Symphony Services v. Barclays and Bombay HC in audit firm cases have cited Bolkiah.

B. Merrill Lynch Research Analyst Conflict - Eliot Spitzer Investigation & Global Analyst Settlement 2002-2003

Facts: NY Attorney General alleged Merrill Lynch research analysts shared confidential IB information and were compensated on basis of IB business. Henry Blodget publicly hyped stocks he internally called "pieces of junk", "crap", "POS" . Firm claimed Chinese Wall separated analysts and retail sellers from investment operations - Spitzer exposed it as "embarrassing fiction" .

Outcome:

• 21 May 2002: $100 million fine.
• April 28, 2003: Global Analyst Research Settlement - SEC, NASD, NYSE and ten largest firms - $1.4bn total, structural reform: complete separation of research and IB, ban on IB compensation for analysts, independent research.

Principle: Chinese Wall cannot be marketing fiction. Physical separation, separate reporting lines, separate compensation, and compliance monitoring required.

C. SEBI v. Bank of America Securities - ADSL AMC Block Deal 2024 (Live Indian Precedent)

Facts: March 2024 - BofA managed $180mn block sale of Aditya Birla Sun Life AMC. SEBI investigation found BofA's deal team, while holding unpublished price-sensitive information, failed to maintain Chinese walls with broking/research arms.

SEBI notice: "The conduct highlights the failure of (the bank's) deal team to maintain Chinese walls with broking/research arms, impacting safekeeping of confidential information and internal controls".

Significance: First major Indian case where regulator explicitly used term "failure to maintain Chinese walls" as independent violation under PIT Regulations, beyond insider trading. Show cause notice issued under Reg 4 & 9. Penalty expected under SEBI's new 2024 framework.

D. Invesco AMC India Settlement Order - April 2024

Facts: SEBI inspection of MF and PMS activities Oct-Nov 2021 found there were no clear segregation of activities, and Chinese wall between PMS and MF activities.

Common dealing desk, same fund managers managing PMS and MF, same research inputs. No separate restricted list.

Outcome: Invesco AMC, CEO Saurabh Nanavati and 4 fund managers settled by paying Rs 4.98 crore under SEBI settlement regulations. SEBI issued guidance that AMC must maintain arm's length and physical separation between MF and PMS.

E. SFC Hong Kong v. Licensed Representative 2008

A former licensed representative of a major bank was banned by SFC for breaching Chinese Wall restrictions and taking "an undisciplined approach to confidential information", although his conduct did not actually result in any insider dealing activities.

Principle: Breach itself is punishable even without actual insider trading profit - it is a control failure.

F. SEBI v. UTI Securities Ltd. (2006)

SEBI order noted broker has not mentioned Chinese wall in internal code of conduct - held to be violation of Schedule I Model Code.

4. Elements to Prove Failure

To defend, firm must show under SEBI/SEC:

1. Written Policy approved by Board
2. Physical & Logical Controls: Separate floors, access cards, password-protected drives, no shared printers
3. Restricted/Grey List maintained by control room
4. Wall Crossing Log with Chinese Wall Crossing Register, need-to-know basis, Compliance pre-clearance
5. Training & Surveillance: Quarterly training, email surveillance, trade surveillance
6. Independent Compliance Reporting

Failure in any = liability. Under Bolkiah test, if confidential info could leak, injunction will be granted even if no leak proved.
