1. What is Sovereign Risk?

Definition: Probability that a sovereign state takes actions that adversely affect value of your loan / investment / collateral.

5 Components banks fail to assess:

A. Transfer & Convertibility Risk [T&C]: Borrower has USD in local bank, but Central Bank refuses to allow USD conversion / transfer. You have money but cannot repatriate. Classic Argentina, Sri Lanka 2022, Nigeria.

B. Political Risk: Expropriation, nationalization, change in law, cancellation of licence. e.g., Govt cancels coal blocks, 5G spectrum.

C. Sovereign Ceiling Risk: Private company in Argentina cannot be rated higher than Argentina itself. If Argentina defaults, all Argentine corporates are deemed to default even if they are solvent.

D. Repudiation Risk: Sovereign directly refuses to honour its own guarantee / bond. e.g., SSNNL bonds guaranteed by Gujarat Govt.

E. Regulatory / Crown Priority Risk: Sovereign tax claim overrides your secured charge. You thought you have first charge, but Income Tax attaches first.

RBI Master Circular on Risk Management: Banking regulation routinely designates domestic government debt as safe, even when risky. This failure to recognize riskiness induces banks to gamble with depositors' funds by purchasing risky government bonds and assets correlated with them.

2. How Banks Fail to Assess

1. 0% Risk Weight Trap: Under Basel, domestic govt bonds get 0% risk weight. Banks assume zero risk. In reality, State Govt bonds [SDL] have default risk.
2. Sovereign Guarantee = No Diligence: Buying PSU bonds with "guaranteed by Govt of Gujarat" without checking if guarantee is unconditional, irrevocable, or has 90-day invocation clause.
3. No CDS / Rating Link: Not tracking Country CDS spread, Moody's Sovereign ceiling, OECD Country Risk Classification.
4. Correlation Blindness: Lending to 10 infra projects all dependent on same State Discom tariff - one sovereign action kills entire pool.

3. Case Laws - Global and Indian

A. GLOBAL HOLDOUT CASES - Sovereign Repudiation

1. NML Capital Ltd v. Republic of Argentina - US SDNY Judge Griesa 2012, US Supreme Court 2014 [573 U.S. 134], UK Supreme Court [2011] UKSC 31
The Bible on Sovereign Risk.
Facts: Argentina issued FAA Bonds in 1994 with Pari Passu clause: "Securities will constitute direct, unconditional and unsecured obligations... shall at all times rank at least equally with all other external indebtedness." In Dec 2001, Argentina defaulted on $100bn. In 2005/2010, it offered exchange bonds at 30c. NML [Elliott Management] refused.
Argentina paid interest on exchange bonds but not on FAA bonds. NML sued.
Held:

• Argentina breached Pari Passu by paying exchange bondholders and not FAA holders - equal treatment provision violated.
• US Court issued injunction: Argentina cannot pay exchange bondholders unless it pays NML ratably. Blocked Bank of New York Mellon from processing payments.
• In Republic of Argentina v NML Capital, Ltd. (2014), Supreme Court held FSIA does not protect sovereign against post-judgment discovery of assets. Banks holding Argentine assets must disclose.

Learning for Banks: Sovereign can default and still choose who to pay. Your guarantee / Pari Passu is only as good as enforcement in New York / London. If you lend to a project whose revenue depends on Argentina paying, you bear that risk.

2. EM Ltd. v. Banco Central de la República Argentina, 2nd Cir. 13-3819-cv (2015)
Plaintiffs owned FAA bonds. Argentina explicitly waived sovereign immunity. Plaintiffs tried to attach assets of Central Bank (BCRA) arguing it is alter-ego of Argentina.
2nd Circuit held: Central Bank is NOT alter-ego unless plaintiff shows control of day-to-day operations or fraud. Failed to prove.
Learning: You cannot pierce sovereign veil to get to Central Bank reserves. Transfer risk is real - even if money is in Central Bank, you cannot attach.

B. SOPHISTICATED INVESTOR DEFENSE - BANK'S LIABILITY FOR NOT WARNING

3. Springwell Navigation Corp v JP Morgan Chase Bank [2010] EWCA Civ 1221 - Court of Appeal, UK - Russian GKO Default 1998
Facts: Springwell [Greek shipping family] invested in Russian-linked structured notes sold by Chase. Notes collapsed when Russia defaulted on GKOs in Aug 1998. Springwell sued Chase for negligent misstatement, failing to warn about sovereign risk and liquidity.
Chase defense: Springwell was sophisticated, aware of risk of sovereign default by Russia.
Court of Appeal affirmed Gloster J absolving JP Morgan Chase Bank of liability for misrepresentation. Held: Springwell was aware of risk of sovereign default by Russia; bank had no duty to warn sophisticated investor who understood risk.

This is key for India: If you sell PSU / State Govt bonds to retail HNI saying "sovereign guaranteed, zero risk", you WILL be liable. If you sell to sophisticated FPI, you may not. Assessment and disclosure of sovereign risk is duty of distributor.

C. INDIAN SOVEREIGN GUARANTEE FAILURE

4. Sardar Sarovar Narmada Nigam Ltd [SSNNL] Bonds Case - Gujarat High Court + Supreme Court 1994-2018 - Myth of Sovereign Guarantee
Facts: In 1994, when interest rates were sky-high, SSNNL issued Deep Discount Bonds with face value Rs 3600, guaranteed by Govt of Gujarat. Face value Rs 11,000 after 20 years. Investors bought assuming sovereign guarantee = safe.
In 2008-2017, SSNNL refused to pay maturity value, offered lower value citing interest rate fall. Investors sued.
Litigation: Bondholders v SSNNL.
Bonds from public sector entities are bought with barely a glance at credit rating. The ongoing legal battle between bondholders and SSNNL offers a cautionary tale on sovereign guarantees.
Court observed guarantee was not unconditional - had to be invoked within 90 days with specific process. Many investors failed to invoke. Gujarat Govt said guarantee is only for principal, not for contracted yield.

Learning: Indian courts held sovereign guarantee is NOT a comfort letter. If guarantee deed says "unconditional and irrevocable" but has invocation period, failure to invoke = loss. Banks must read guarantee deed, not rely on label.

5. SBI v. Tax Recovery Officer (2022) - Madras High Court + Builders Supply Corp v Union of India (1965) SC
Held: Tax recovery by State, being sovereign function, enjoys constitutional priority over private debts. Secured creditors are expected to conduct due diligence and cannot claim ignorance of pending tax liabilities.
Impact: You have first charge under SARFAESI. Income Tax Department attaches same property for prior tax dues. Your charge fails. This is sovereign priority risk. RBI now requires search of tax dues before lending.

6. Three Rivers District Council v. Governor and Company of The Bank of England [House of Lords] - BCCI Collapse
Claimants alleged Bank of England knew BCCI was failing but gave banking licence and failed to supervise, causing depositor losses. House of Lords laid down test for misfeasance in public office. While claim failed on facts, it established that regulatory failure is itself sovereign risk - reliance on central bank supervision does not absolve your credit assessment.

D. ARBITRATION - BIT CASES

7. CMS Gas Transmission Company v. Argentine Republic - ICSID Case No. ARB/01/8 (2005)
US investor in Argentine gas transport licence. Argentina froze gas tariffs in 2001 crisis. CMS sued under US-Argentina BIT. Tribunal awarded $133m. Held Argentina violated fair and equitable treatment. Shows even if private counterparty pays, sovereign change in law can kill project IRR.

Argentina has 50+ such ICSID cases after 2001 default - textbook failure to assess transfer and political risk.

4. RBI / Basel Framework for Assessment - How to Avoid Failure

RBI expects:

1. Country Risk Rating: As per FEDAI guidelines, classify countries into 7 categories - Insignificant to Off-Credit. Provision from 0.25% to 100% even if borrower is private but country is high risk.
2. ECB Correlation: If borrower income is in INR but loan in USD, sovereign risk of India [INR depreciation due to sovereign rating downgrade] must be assessed.
3. State Government Risk: Do NOT treat SDL / State PSU guarantee as Central Govt. RBI circular: State Govt guarantee does NOT get 0% risk weight unless explicitly backed by Central Govt guarantee fund.
4. Hedging: For ECB, RBI requires mandatory hedging of 70% of exposure for >5 year loans. Failure to hedge = transfer risk.

Checklist before lending to pool dependent on sovereign:

• Read Guarantee Deed: Is it unconditional, irrevocable, payable on demand without demur? Does it have expiry?
• Track CDS: 5-year India CDS > 150 bps = stress.
• OECD CRC: India is currently 3/7 - medium risk.
• Check Pari Passu in bond prospectus: Does it have collective action clause [CAC]? If 75% agree, you are forced to restructure.
• Tax search: I-Tax, GST, EPF dues have sovereign priority.
