Greek Debt Restructuring PSI: CACs, Haircuts, and CDS Trigger

Key Takeaways

• Greece's 2012 PSI imposed a ~75% present-value loss on private holders of €197 billion in bonds, the largest sovereign restructuring in history by notional exchanged.
• The operation only succeeded because the Greek parliament retroactively inserted collective action clauses into domestic-law bonds on February 23, 2012, binding holdouts who controlled 17.5% of the eligible stock.
• Investors underestimate the ECB's preferential treatment: official holders were exempted from the haircut through a pre-PSI bond swap, subordinating all private creditors in the same restructuring.
• The Greek CDS credit event settled at a recovery of 21.5 cents, paying protection buyers 78.5 cents per dollar, the trigger worked exactly as designed, though net notional was only about $3.2 billion.

What It Is

PSI was the voluntary bond exchange offered in February and closed in March 2012 as part of the Second Economic Adjustment Programme for Greece. Holders of old Greek bonds received a package of new instruments with longer maturity, lower coupons, EFSF short-term notes, and GDP-linked warrants. The operation reduced Greece's debt stock by approximately €107 billion in one transaction.

PSI was layered on top of an IMF-EU-ECB conditional financing program and was explicitly a precondition for the second bailout.

The Intuition

By early 2012 Greek debt was clearly unsustainable. IMF staff analysis put the debt at roughly 165% of GDP and rising. Even with full program implementation, the debt trajectory was explosive. A restructuring was required; the political and institutional design questions were who took the loss, how large, and through which legal mechanism.

The obstacle was legal. About €177.3 billion of the eligible Greek debt stock was governed by Greek law, and the old bond indentures did not contain collective action clauses. Under the original contracts, any individual bondholder could have blocked a restructuring of their series by refusing to tender. With thousands of holders, unanimity was impossible. A voluntary exchange would have left a large holdout residual, which could then sue.

The Greek authorities, with euro-area approval, found an unprecedented fix: change the contract terms retroactively by act of parliament.

How It Works

The Greek Bondholder Act (Law 4050/12). Passed on 23 February 2012, the act retroactively inserted aggregated collective action clauses into Greek-law government bonds. The CAC allowed a two-thirds quorum and a two-thirds majority of participants to bind all holders of the affected series. Roughly 93% of Greece's outstanding bonds fell under Greek law, so the act covered most of the debt stock.

The exchange package. Each €1,000 of old bonds received:

• €315 face in 20 new Greek-law bonds (coupons 2-4.3%, maturities 11-30 years)
• €150 face in short-term European Financial Stability Facility (EFSF) notes (1-2 year PSI-payment notes)
• €315 notional in GDP-linked warrants
• Accrued interest settled in EFSF notes

The face-value haircut was 53.5% (1,000 minus 465 = 535). Because the new bonds had lower coupons and longer maturities, the present-value loss at reasonable discount rates was roughly 75%.

The voluntary tender. Greece first solicited voluntary tenders. Roughly 82.5% of Greek-law holders and a smaller share of foreign-law holders tendered voluntarily. Greece then activated the newly inserted CACs for Greek-law bonds, binding the remaining holders. For foreign-law bonds, which did not fall under the retroactive act, some holdouts remained and were paid in full or pursued litigation.

The CDS trigger. ISDA determined on 9 March 2012 that the use of CACs constituted a credit event. The auction settled recovery at 21.5%, paying CDS protection buyers 78.5 cents per dollar. Net CDS notional outstanding at the time was roughly $3.2 billion, a fraction of the €197 billion restructuring.

Worked Example

A European insurance company holds €100 million of Greek-law 10-year bonds bought at par. In February 2012 the market price is roughly 20 cents. The company faces three choices.

Hold out and sue. Possible only for foreign-law holders. For Greek-law holders, the CAC vote is binding once the supermajority threshold is reached.

Tender voluntarily. The company receives €31.5 million face in new Greek-law bonds, €15 million in EFSF notes, and €31.5 million notional in GDP warrants. Mark-to-market on 9 March 2012: roughly €25-30 million total, a loss of about 70-75%.

Wait for the CAC. If the company does not tender but the CAC binds its series, it receives the same package. No extra value from non-participation.

Post-PSI, Greece's debt-to-GDP fell from roughly 160% to a post-deal level that was still high but the trajectory became briefly sustainable under program assumptions. Further relief came from official-sector measures: lower interest rates on bilateral and EFSF loans, extended maturities, and the 2012 ECB Securities Market Programme profit refunds (ANFA/SMP). The Eurogroup also extended the maturity of Greek loans repeatedly through 2018.

Common Mistakes

1. Treating PSI as a negotiation between equals. It was not. Holders were given a choice between tender and CAC-binding. Economic outcomes were effectively identical. The voluntariness was legal formality. Retail holders in Greece sued unsuccessfully; the European Court of Human Rights upheld the restructuring in the Mamatas judgment.

2. Underestimating how much relied on local-law status. Only Greek-law bonds could be retrofitted with CACs. Foreign-law bonds (roughly 7% of the stock) could not be altered by Greek legislation and had to be bought out or held out. This is a key lesson for EM sovereign investors: foreign-law issuance is credit-positive precisely because it resists unilateral modification.

3. Assuming PSI fixed the debt problem. It reduced the stock but did not resolve the flow. Greece required a third bailout in 2015 and additional bilateral debt relief in 2018. The 2012 operation was necessary, not sufficient. Restructuring without growth recovery is a sequence of restructurings.

4. Ignoring the ECB's preferential treatment. The ECB and national central banks held Greek bonds in their Securities Market Programme portfolio and were exempted from the haircut through a pre-PSI bond swap. Private investors took the hit; official holders were protected. This subordination issue has been controversial in every restructuring since.

5. Overreading the precedent. After 2012, the EU mandated CACs in all new eurozone sovereign bonds from January 2013. The retroactive Greek fix was a one-off enabled by the fact that the old Greek bonds had no CACs and were under Greek law. It is not a replicable template for other EU sovereigns whose new debt already contains CACs.

Frequently Asked Questions

Q: What was the Greek debt restructuring PSI in simple terms? In March 2012, the Greek government exchanged €197 billion of old bonds for new ones worth about a quarter as much in present value. Private investors took the loss; the ECB and other official holders were exempted. The deal was made legally binding on holdouts by inserting new voting rules into Greek-law bond contracts through a parliamentary act.

Q: How did the Greek PSI affect investment decisions? It demonstrated that local-law sovereign bonds can be restructured by domestic legislation, regardless of original contract terms. It also established that official creditors (ECB, IMF) rank above private holders in a eurozone restructuring. Both lessons directly affected how investors price sovereign bonds under local versus foreign law.

Q: What is a specific example of how the Greek PSI mechanics worked? A European insurance company holding €100 million of Greek-law 10-year bonds tendered in the exchange and received roughly €31.5 million face in new Greek bonds, €15 million in EFSF notes, and €31.5 million in GDP warrants, a mark-to-market value of about €25–30 million, a 70–75% loss on face. Those who held out of Greek-law series were bound anyway by the retroactive CAC.

Q: How can investors use knowledge of the Greek PSI? Check whether a sovereign's bonds are governed by local or foreign law. Local-law bonds are more restructurable unilaterally; foreign-law bonds (New York, English) are harder to modify without individual creditor consent. Also assess whether the ECB or bilateral official creditors hold large shares, if so, private investors face de facto subordination.

Q: How is the Greek restructuring different from Argentina's defaults? Greece restructured through a legislatively backstopped voluntary exchange inside the eurozone institutional framework. Argentina defaulted outright, rejected the IMF, and faced litigation from New York holdouts for over a decade because its bonds lacked aggregated CACs. Greece's aggregated CAC retrofit, while controversial, resolved the holdout problem in weeks rather than years.
