Euros without the Eurozone

This 2 euro coin is issued by Monaco, which is not a member of the Eurozone

Grexit isn't what people take it to be. The standard narrative is that Greece is approaching a fork in the road. It must either stay in the euro or adopt a new currency. I don't think this is an entirely accurate description of the actual fork that Greeks face. Over the next few months, Greece will either:

• A) stay a member in good-standing of the institution called the "Eurozone" and continue to legitimately use that institution's currency, the euro, or
• B) leave the Eurozone while continuing to use the euro 'illegitimately.'*

This means either the status quo of de jure (official) euroization or de facto (unofficial) euroization. In both cases, the euro stays.

The probability of a new drachma emerging is awfully low. The widespread idea that a sick country can rapidly debut a new currency and, more importantly, have that currency be universally adopted as a unit of account is magical thinking. Greece has been using the euro as a universal "language of exchange" for fifteen years. Switching over to a new unit is about as unlikely as Greeks suddenly beginning to speak German, network effects and all. Consider too the fact that Greeks don't want the drachma—they have consistently voted for euros. Syriza has no mandate to bring a new unit into existence. ***

Option B isn't an odd one. All sorts of countries 'illegitimately' piggy-back off the currencies managed by others. Zimbabwe, Ecuador, and Panama use the U.S. dollar without being card carrying members of the Federal Reserve System while Andorra, Kosovo, Montenegro, Monaco, San Marino, Vatican City use euros without being part of the Eurozone. Nor can the Eurozone can do anything to prevent de facto adoption of the euro by Greece. It's a decision that Greeks get to make themselves.

If Greece leaves the Eurozone on a de jure basis while staying a euro user, what will it be giving up?

The Greeks would NOT be losing the price stability and commonality already provided by Eurozone membership. These are presumably the features that lead most Greeks to declare in polls that they want to stay in the euro.

However, Greece would no longer get access to Eurozone lender of last resort facilities. One could argue that the nation would be better off without these facilities, given the discipline that a true 'no bailout' policy would enforce on both the banks and the government. Greece also loses direct access to the monopoly supplier of euro banknotes. A Greek banker can currently ask to have their Eurozone account be debited and a batch of freshly printed paper euros trucked over to their vault. Gone is that functionality. Panama has survived, even prospered, for decades without access to the Fed's discount window or Fed cash facilities.***

Greece would also lose its seat on the ECB Governing Council and therefore any say in determining monetary policy. Greece's one seat probably never gave it much influence anyways, especially compared to Germany's dominant influence in ECB decision making. Nor would Greek data be considered as an input into Eurozone policy decision should Greece leave. However, as it clocks in at just 2% or so of the Eurozone's total size, Greece's data could never have had much influence on the aggregates that ECB policy makers watched to begin with. Official user of euros or unnoffical, Greece will always lack an independent monetary policy.

Another concern is that Greece might not be allowed to use the ECB's Target2 real time settlement mechanism anymore. However, Denmark, Bulgaria, Poland, and Romania all connect to Target2, despite not being Eurozone members. Surely Greece would qualify. If not, it wouldn't be too complicated for Greek banks to set up their own payments system.

Lastly, Greece would forfeit all seigniorage revenues. Eurozone members currently get a share of the profits that the ECB earns on its monetary monopoly. I don't see this loss as being a big deal. Seigniorage has long since been eclipsed by taxes as the key source of a modern government's revenue.

The upshot is that whether Greece remains a legitimate member of the Eurozone or an unofficial user of the Eurozone's chief monetary product, the implications are about the same. There is no fork in the road, at least not from a monetary policy perspective; just a continuation of the same euro path as before.

I've left two features out. If Greece leaves, the claims and liabilities it has on the Eurozone must be unravelled and settled. Having invested around 200 million euros in the ECB when it was formed, Greece would have to be bought out by remaining Eurozone members at a reasonable price. Counterbalancing this would be Greece's obligation to unwind the debt that it has amassed to the Eurozone in the interim. This debt, known as its Target2 deficit, currently clocks in at around 100 billion euros, far in excess of the capital it is owed. It would take an incredible outlay of resources to pay this amount off. The advantage to the Greek population of staying in the Eurozone is that their debt need never be settled. After all, Target2 debts are by nature perpetual. Only by leaving do they face a final day of reckoning.

However, if Greece puts little-to-no cost on squelching on its debts, it may as well just leave the Eurozone without paying back the 100 billion it owes. It gets to continue to ride piggy-back on top of the euro, enjoying (almost) all the same benefits of being a Eurozone member, without being on the hook for anything. Why not perpetually bum cigarettes rather than pay for them?

Which is why Greece has a certain degree of power over the remaining Eurozone members. Should it shrug and leave, the remaining members are on hook for its unpaid tab. And once Greece goes down the de facto euroization path, how long before the next largest debtor to the rest of the Eurozone decides to shrug and leave? As Nick Rowe says, the last one holding a common currency is the sucker since they'll be left with everyone's bad debts. To keep the system going, the Euro project's architects need to do their best to ensure that Greeks aren't incentivized to just shrug and bum a free ride on the euro. I don't envy them their task, it's a difficult one.

The other aspect I've left out is the Greek banking system, which is probably insolvent. Once cutoff from the central bank that prints the stuff, Greek banks simply wouldn't be able to meet the rush to convert deposits into euro banknotes. The only way to return the banking system to functionality would be to chop the quantity of Greek bank deposits down to size so that the banks' asset base would be sufficient to absorb the run into cash. We're talking a multi-billion euro "bail-in" of depositors. The prospect of such a hit certainly tilts the decision between A and B back towards A.**


* Having been cut off from additional ECB lending, one might argue that Greece has already gone halfway towards exiting the Eurozone.

Note: apologies for the constant additions, but this subject is complex and the situation getting more complex by the day, so rather than writing two or three posts I'm adding bits to the original.
