In short, a restructuring of Greek debt is paramount to solving the crisis as the country will be unable to support its current and future debt loads. If Greece was not part of the European Union and the Euro, it would've likely already restructured its debt and devalued its currency. In this case, private owners of the debt would see a potential loss conservatively between 30-50% of the principal.
The problem is that private investors are not the only significant owners of Greek debt. The European Central Bank is estimated to own E40 billion and has stated emphatically that it doesn't want a restructuring or default. This past week, ECB President Jean-Claude Trichet stated, "We would say it's an enormous mistake to embark on a decision that would lead to a credit event (for Greece)." Also, private investors are dumping the debt, reducing their exposure and putting more of the debt back on to the public sector. (As an example, Germany's Die Welt paper says German insurance companies have dumped nearly half their holdings and German banks have dumped 40 %.)
What does this all mean? Greece's debt burden is unsustainable, additional debt is unlikely to solve the issue and a restructuring will cause the ECB to take losses on the Greek debt they hold despite their vocal opposition to it. The added difficulty with Greece is that a restructuring for them will likely trigger a restructuring for Ireland and Portugal as well. Therefore, the deal will need to involve many interested parties and necessitate buy in from them. This will not be a simple task and there will likely need to a strict deadline to be met to create a crisis-like condition to mandate a solution.
Given this, what form could a restructuring look like? Throughout the last 30 years, there have been numerous successful sovereign restructurings from Mexico in 1982 to Argentina in 1992 Uruguay in 2003. All were innovative and all required assistance from both the private and public sectors including regulators. I believe a Greek solution will require a hybrid of these to solve the multitude of problems.
First, there will need to be a backer of new debt to be issued to replace old Greek debt coming due. Like Mexico in the 1980s, there will likely be a choice offered to current debt holders to swap into new debt. The first choice could be a 30-50% forgiveness of loans in exchange for the remaining 40-60% new floating rate debt collateralized by EU bonds. The second choice could be a swap for bonds backed by EU bonds that maintain face value, but at interest rates significantly below market levels. For either choice, there must be a back stop for this to work or it must be the European Union.
Next, the credit rating agencies must be consulted and bargained with to ensure they not only view this positively, but also agree that this won't trigger a credit event. This will mean that credit default swaps will not have their clauses triggered and the domino effect onto other nations will not occur. How each service views the ultimate deal will likely shape the structure of the deals. Clearly, the language is key and "voluntary" appears to be critical for the process to avoid a technical default. However, governments can put tremendous pressure on these firms to participate in their approval.
Also, key regulators within the European Union and the United States will need to give tacit approval that no additional capital set aside will be required should banks go along with the deal. This was a critical component for the 1982 Mexican restructuring when Federal Reserve Chairman Paul Volcker participated. Given the recent mandated increases in global regulatory capital from Basle III, this part will be needed or banks will not agree to participate.
Finally, the European Central Bank will likely have to be made whole on their holdings of Greek, Irish and Portuguese debt. While the ECB is seen to hold E40 billion of Greek debt, its total holdings of government bonds of peripheral euro-zone countries is more than E75 billion.
To summarize, it is clear from the recent report from the IMF/ECB/EC that Greece's debt burden is unsustainable and therefore they will not be able to return to the global capital markets any time soon to refund their debt. This mandates that a restructuring must take place to solve the problem. Investors will most likely be given a choice of bonds to swap their current holdings with potentially one being partial forgiveness with a market floating rate and the other being a fixed rate, but greatly reduced from current market. Both bond choices will need to be collateralized from the European Union or an entity that has the backing of the European Union. Finally, the European Central Bank must be made whole on the losses stemming from the restructuring.
