1. DEFINITION

Overhang refers to a sizable block of securities or commodities contracts that are ready for release into the market. If released, would put downward pressure on prices; prohibits buying activity that would otherwise translate into upward price movement. [Nasdaq definition]

Collateral Overhang = Specific type of overhang where:

1. Commodity inventory is hypothecated/pledged to Bank A as collateral
2. Same inventory is either:
   • Sold in physical market without releasing pledge
   • Pledged again to Bank B via duplicate warehouse receipts
   • Never existed - fake receipts
3. Result: On paper, there is Rs 1000cr of oil in tanks backing loans, in reality tank is empty or water. When default happens, all lenders rush to enforce, but there is no oil. The overhang collapses price because market realizes supply was double-counted.

Why commodities are vulnerable:

• Unlike house, oil in tank looks identical - commingled, stored in way that makes identification difficult, or subject to upstream retention of title, lender may discover its collateral sits behind stronger claims
• Warehouse receipt can be forged easily
• Financing bank must have priority over all other lenders to realised proceeds of commodities, but in many jurisdictions only way to get legally effective security is to take actual or constructive possession - which banks don't do

2. THREE FORMS OF OVERHANG

a) Rehypothecation Overhang: Borrower has 100,000 MT oil worth $50M, pledges to 5 banks for $40M each = $200M loans on $50M collateral. Common in India with collateral management agencies.

b) Sale Without Release Overhang: Borrower pledges oil to bank, then sells same oil to trader on credit. Trader thinks he owns oil, bank thinks it owns oil. This is Hin Leong model.

c) Ghost Collateral Overhang: Warehouse receipt shows mentha oil barrels but barrels contain water - substitution fraud. Seen in Indian case National Bulk Handling Corporation.

3. MAJOR CASE LAWS

CASE 1: Hin Leong Trading Pte Ltd + ZenRock Commodities - Singapore 2020 - $4 BILLION OVERHANG

The most important collateral overhang case in oil history.

Facts:
Hin Leong, founded by O.K. Lim in 1963, was Asia's largest independent oil trader. In April 2020, crash in oil prices exposed fraud.

• Founder confessed to having concealed over US$800 million in futures losses and directing forgery of trade documents to secure US$3.85 billion in credit from over 20 banks, while secretly selling off oil pledged as collateral
• Told banks: oil pledged as collateral for loans had been sold to raise cash, leaving combined exposure of US$3.3 billion
• At same time that Hin Leong was pledging fuel to back loan, it allegedly agreed to sell same cargo to another trader, who sought letters of credit from another bank - this line of credit merry-go-round was fraudulent tool
• Unicredit issued $37M LC to Hin Leong for 150,000 MT fuel oil from Glencore - this was buyback transaction where seller simultaneously buys back goods - made 5 months before collapse

Legal Proceedings:

• Singapore Police charged Lim Oon Kuin with forgery
• 23 banks including HSBC, DBS, ABN AMRO filed claims in Singapore High Court
• Supreme Court Singapore: In case brought by bank alleged fraud had occurred - court held bank that issued LC on fraudulent underlying transaction cannot claim as holder in due course if fraud proven
• Lim sentenced to 17 years in 2024 for cheating HSBC over $112M - case centred on allegations Hin Leong had been hiding losses and selling off oil inventories already pledged as collateral for loans

Legal Principle:
Collateral overhang = criminal breach of trust + cheating. Bank's security fails if bank did not take constructive possession via independent collateral manager. Paper pledge without physical verification = unsecured.

CASE 2: OW Bunker A/S - Denmark / UK 2014 - $1B Bunker Overhang

OW Bunker, largest marine fuel supplier, collapsed. It had pledged same bunker inventory to ING Bank under English law floating charge, and also sold bunkers to shipowners on retention of title.

UK Supreme Court in PST Energy 7 Shipping LLC v OW Bunker Malta Ltd UKSC 23 held buyers had to pay twice - once to OW Bunker's bank (who had collateral), once to physical supplier who had not been paid. Created double-payment overhang.[2016]

Principle: Under Sale of Goods Act 1979, ownership of bunkers sold does not pass until paid, even if collateral pledged. Led to litigation concerning ownership of bunkers sold to OW Bunker and rights under SGA.

CASE 3: India - National Bulk Handling Corporation Pvt Ltd - Mentha Oil Substitution Fraud - Supreme Court

Background:
Respondent National Bulk Handling Corporation was engaged in collateral management services, providing storage facilities for commodities pledged by farmers, traders, manufacturers to financial institutions.

Punjab & Sind Bank financed mentha oil traders. Traders stored barrels in NBHC warehouse, pledged warehouse receipts to bank. Later when bank enforced, barrels contained water, not mentha oil. Employee colluded to replace oil with water.

Supreme Court - Fidelity Insurance Claims:
Court ruled on extent of insurer's liability in cases of employee fraud - clarified insurance covers dishonest act of employee replacing mentha oil barrels with water.

Principle for India:
Collateral manager owes duty as bailee under Sec 148-171 Contract Act. If commodity collateral exceeds 15% - benefit of collateral - Clearing Corporation rules apply, but for commodity financing, bank must ensure collateral manager has independent weighing, sampling. Failure = bank's loss, not borrower's.

CASE 4: PNB - Nirav Modi LoU Overhang - 2018 - Rs 13,500 Cr

Though diamonds, same overhang logic as commodities.

Modus operandi: Three diamond firms belonging to Nirav Modi Group held current accounts at PNB Brady House. Junior official fraudulently issued Letters of Undertaking allowing Nirav Modi group companies to get short term buyers' credit from overseas branches to pay sellers. Under terms of LoU, PNB was guarantor.

Firms used LoUs to import diamonds from related firm A Jaffe, also Nirav Modi firm. Money used to pay off A Jaffe. Simultaneously another firm Firestar Diamond applied for credit from PNB and Vijaya Bank, which was then used to pay off Diamond R's outstanding LoU - vicious cycle of LoUs.

No underlying commodity import actually happened - circular trading.

Legal Outcome: CBI + ED cases, PNB recovered. Principle: LoU is collateral - if bank does not verify underlying commodity movement via collateral management, it creates ghost overhang.

4. HOW COURTS HANDLE COLLATERAL OVERHANG ISSUES

Issue 1: Priority - Who owns pledged commodity that was sold?
Rule: First to take constructive possession via collateral manager wins. Paper pledge without possession = second. In India, under SARFAESI, if commodity is in possession of collateral manager acting as agent of bank, bank has priority over buyer under Sec 26E SARFAESI (2016 amendment).

Issue 2: Double Financing - Same Warehouse Receipt pledged twice
Under Indian Contract Act Sec 172 pledge requires delivery of goods. If same receipt pledged to two banks, second pledge void - first pledgee can sue second bank for conversion. Seen in NSEL crisis 2013 - FTIL NSEL had same commodity stock shown to multiple banks.

Issue 3: Value of Overhang - Price Suppression
When overhang discovered, market knows extra supply will hit. Example: When Hin Leong revealed $800M losses and that pledged oil had been sold, oil price fell further because market thought 1M barrels extra would be liquidated.

5. HOW TO PREVENT OVERHANG - LEGAL CHECKLIST

For banks in India financing commodities (as per RBI + NCCL rules):

1. Mandatory Collateral Manager: Must be independent - NCML, NBHC, Star Agri - not borrower controlled
2. Daily Marking: Commodities as collateral - benefit withdrawn if security discontinued from approved list
3. No Commingling: Must have separate tanks, assay, not mixed with other clients
4. Insurance: Fidelity + Burglary policy covering substitution fraud (mentha oil case)
5. No Re-pledge: Under CRR rules - for commodities to be eligible collateral for purposes of CRR, security arrangement must satisfy conditions including bank must have priority over all other lenders to realised proceeds
