Sergio Cesaratto Gli scenari del teatrino europeo

2010

Il 16-17 dicembre si riunisce in Belgio il Consiglio dei leader europei. Quali sono gli scenariche lEuropa ha di fronte?

Alla irrisolta crisi di solvibilit della Grecia si in questo autunno aggiunta quella dellIrlanda

e a ruota il contagio, che si manifesta con un aumento dei tassi di interesse sui titoli pubblici,

arrivato anche allItalia via Portogallo e Spagna e ora persino alla Germania. Quali sono le

prospettive? Abbiamo di fronte tre scenari: 1) tamponare con un po di liquidit la situazione

dei paesi periferici chiedendo loro di aggiustare i propri conti con sacrifici interni;. 2)

anticipare la rottura e gestirla evitandone gli aspetti pi dolorosi, per quello che si pu; 3)

attaccare i problemi alla radice nella direzione di costruire una unione politica ed economica

funzionante.

La crisi europea assomiglia alle molte delle crisi debitorie nei i paesi in via di sviluppo il cuiultimo clamoroso caso stato il default dellArgentina nel 2002. In pillole, la costituzione

dellUnione monetaria europea (UME) nel 1999 ha favorito flussi di capitale a buon mercato

dai paesi centrali dellEuropa (Germania e Francia in primis) a quelli periferici, i famosi

PIGS. La politica monetaria della BCE stata al contempo improntata a bassi tassi nominali

di interesse essendo ritagliata sulla Germania, per compensare le sue politiche di moderazione

fiscale e salariale che poco sostenevano domanda e produzione. I flussi di capitale hanno

determinato un boom edilizio e lindebitamento delle famiglie in Spagna e Irlanda, e del

settore pubblico in Grecia. Ledilizia un volano delleconomia questi paesi sono infatti

cresciuti assai, e cos i loro salari nominali e prezzi. Questo ha implicato che i tassi di

interesse reali[1] diventassero, in quei paesi, assai bassi, stimolando ancor di pi la domanda.La produttivit i questi paesi cresciuta pi che in Germania, ma qui i salari nominali

crescevano meno della produttivit, nella periferia essi aumentavano pi della produttivit,

sicch essa perdeva competitivit. La Germania e il suo entourage (Austria, Paesi Bassi ecc)

guadagnava cos in termini di esportazioni nette verso la periferia sia perch la domanda in

quei paesi cresceva molto, che per la loro perdita di competitivit. Nei fatti le esportazioni di

capitali dai paesi centrali finivano per finanziare lacquisto di prodotti dai medesimi paesi. Ma

se questo accade per una serie di anni, i paesi periferici finiscono per cumulare un forte debito

estero. Inizialmente questo era, in Spagna e Irlanda, solo privato, ma ad esso si aggiunto,

una volta scoppiata la crisi, quello del settore pubblico che si indebitato a sua volta per

soccorrere le banche nazionali indebitate con quelle dellEuropa centrale. Se i paesi creditori a

un certo punto ritengono che i debitori non possano restituire il debito, possono smettere dirifinanziarglielo, e i debitori dichiarano la bancarotta (default).

Una soluzione a questa situazione implica: a) nel breve periodo assicurare a questi paesi

liquidit sufficiente e a buon mercato per non fallire; e b) nel medio periodo risolvere il loro

problema di solvibilit stimolando il loro output ed esportazioni. Esaminiamo dunque i tre

scenari.

1. Nel primo scenario, gi in opera, gli aiuti europei e una timidissima BCE tamponano la

crisi di liquidit sostenendo i titoli dei paesi debitori qualora i mercati non vogliano pi farlo o

lo farebbero solo a tassi esorbitanti, ma lo fanno in misura insufficiente senza davvero

incidere sui tassi usurai che tali paesi si trovano a pagare (i quali aggravano il debito). Al

contempo la deflazione fiscale e salariale loro richiesta determina una caduta del loro PIL, conconseguente caduta delle entrate fiscali, sicch il riaggiustamento dei conti una fatica di

Sisifo (per non parlare dei sacrifici sociali che ci comporta). Tradizionalmente aggiustamenti


2/8

dei conti interni sono stati accompagnati da una svalutazione della moneta, che rilanciando le

esportazione ne ha compensato i danni sul PIL. Ma ora le monete nazionali non ci sono pi!

Per giunta la stessa Germania si fa campione della deflazione, e ci aggrava la crisi della

domanda aggregata a livello europeo e globale. I mercati tutto questo lo sanno, e per questo il

fallimento dei paesi periferici e della moneta unica allordine del giorno. Se fanno

fallimento i paesi debitori, faranno anche fallimento i paesi creditori (USA inclusi) e questasarebbe la madre di tutte le crisi.

2. Una rottura ordinata dellUME, con la fuoriuscita dei paesi periferici, affare

complicatissimo (Blejer and Levy-Yeyati 2010; Eichengreen 2010). Il fatto centrale di cui

tener conto che il debito esterno di tali paesi continuerebbe a esser denominato in euro.

Misurato nelle nuove valute locali, che cadrebbero di valore, e di molto, rispetto alleuro, il

valore di quel debito aumenterebbe, per cui esso dovrebbe certamente subire quello che si

chiama un haircut (un taglio dei capelli), cio essere rinegoziato (ci si accorda che una parte

non viene restituita, e il resto restituito in tempi pi lunghi). Ma se i mercati subdorano questa

eventualit, la speculazione si scatenerebbe determinando un immediato disordinato

default. Allora la decisione di una rottura dovrebbe essere segretamente presa prima che imercati sospettino qualcosa dunque un po prima che il sistema crolli di suo -, in un

consesso che non pu escludere, tuttavia, USA, Cina e Giappone, almeno, oltre ai principali

paesi europei. Nei tempi di Wikileaks tenere il segreto non facile! Il vantaggio di riacquisire

la propria moneta sarebbe nel rilancio delle esportazioni, ma misure per impedire che si

scateni una forte inflazione interna sarebbero necessarie. Non sarebbe invece necessario

stampare preventivamente nuove banconote, le attuali gi sono contraddistinte per paese (una

S dopo il numero di serie individua per esempio quelle italiane). Misure drastiche di

controllo dei capitali sarebbero ovviamente necessarie. Se fosse la Germania (e forse una

recalcitrante Francia) a lasciare, ci costituirebbe di per s un taglio ai debiti esteri denominati

in una moneta, leuro, che svaluterebbe rispetto al nuovo Deutsche Mark. Se poi ci che

rimane dellUME si sfasciasse, tutti si tornerebbe alle monete nazionali e il debito esterosarebbe denominato in quelle, il che sancirebbe un haircutdi fatto.

3. Linefficacia del primo scenario, e la drammaticit del secondo, potrebbero col tempo far

addivenire a soluzioni pi ragionevoli. Con riguardo ai problemi di sostenibilit a breve, una

pi incisiva azione della BCE nel sostenere i titoli di stato e la europeizzazione di parte dei

debiti (come proposto, fra gli altri, da Tremonti) assicurerebbe i mercati consentendo un loro

rifinanziamento a costi contenuti. I problemi strutturali dovrebbero essere poi affrontati

invertendo la moderazione fiscale e salariale tedesca di modo che tale economia perda un po

di competitivit e al contempo rilanci la domanda interna[2]. Daltronde solo operando con

misure opposte a quelle che hanno caratterizzato sinora lUME se ne possono invertire le

tendenze. Questo appare al momento inaccettabile alla Germania che fonda il proprio modello

di crescita su disciplina interna ed esportazioni con in mente lespansione nei paesi extra-

europei.

Se dio veramente acceca chi vuole perdere, nel meeting del 16-7 dicembre i paesi europei

decideranno piani draconiani di rientro dal debito pubblico a cui nostro paese arriver senza

un governo che possa autorevolmente opporsi a tale follia.

[1] Il tasso di interesse reale la differenza fra il tasso di interesse nominale e il tasso di inflazione. Se

prendiamo 100 in prestito al tasso nominale del 5%, e il tasso di inflazione del 4% (per cui ci che

restituiremo fra un anno vale il 4% di meno in termini di potere dacquisto), il tasso reale che

effettivamente paghiamo 1%.

quel paese al tassi di crescita della produttivit pi il 2% che il tasso di inflazione obiettivo della BCE.Il

Leaving the euro: Whats in the box?

Mario I. Blejer Eduardo Levy-Yeyati21 July 2010

Rumours of Eurozone break-up are mounting. This column argues that exiting a strong

currency for a weak one poses almost unthinkable challenges, from the redenomination of

contracts and the imposition of bank restrictions to the restructuring of external debt and

limiting of capital mobility. Lessons from Argentina illustrate just how radical the changes

would need to be.

The turmoil in Europe is not abating. True, some calm has returned to the markets after the

initial storm, but tenacious misgivings about the euro project in general are growing, driven

by disenchantment with the policy responses and a realisation of the magnitude of the

problem.

Something that was unthinkable six months ago is happening today. There are, still few

indeed, but undeniable mounting calls for euro exit and not only from euro sceptics across

the Atlantic (see Feldstein 2010, Financial Times 2010, and Baldwin 2010for a summary of

the debate on Vox.)

While faint exit pleads could be heard in Germany, as a way to avoid bearing the cost of the

bailout, the louder calls are coming from the economies under pressure and looking to regain

competitiveness, with Greece in front of a potentially larger number of countries willing or

forced to give up the single-currency project.

Switching from a strong to a weak currencyBut the process of launching a new, weaker, national currency to substitute a stronger one as

legal tender is, to be sure, a very complex one. What do we know about this process?

Eichengreen (2007) provides an analysis of this event but when it comes to hard facts the

answer is simple. We know virtually nothing.

Indeed, it is unclear whether those toying with this type of solution have analysed the

preconditions and consequences of such a move since there is not much precedent for an

episode of this kind in recent economic history.

Abandoning a battered currency in favour of a stronger one (dollarisation in the jargon) hasbeen more frequent, and is probably easier in comparison (see for example Levy Yeyati and

Sturzenegger 2002). Creating or reintroducing a national currency with the deliberate

intention to weaken itrelative to the existing one (and to all other world currencies, for that

matter) is an altogether different and much more complicated endeavour, particularly if this

has to be done in times of distress and mistrust of domestic policies.

Argentina 2002The closest, although certainly not identical, precedent to this course of action is Argentines

exit from a currency board arrangement to float a weakening peso in 2002, an event that has

important common aspects with the case in point. While still far, in many respects, from anew drachma or a new peseta, the episode nonetheless offers some interesting pointers as

to what the whole affair involves.
http://www.voxeu.org/index.php?q=node/5325http://www.voxeu.org/index.php?q=node/3573http://www.voxeu.org/index.php?q=node/5034http://www.voxeu.org/index.php?q=node/5034http://www.voxeu.org/index.php?q=node/5325http://www.voxeu.org/index.php?q=node/3573http://www.voxeu.org/index.php?q=node/5034


4/8

At the risk of generalising and omitting, the Argentine lessons can be summarised under four

categories. If a country is willing to seriously entertain the idea of introducing a new, weaker,

currency (which for simplicity we could call the peso), it needs to be willing to deal with:

the peso-ification of contracts,

the imposition of heavy restrictions to commercial bank operations,

an external debt restructuring, and

the use of capital and exchange controls at least temporarily.

Crucially, all of these four types of tribulations, which come on top of the potential

inflationary consequences that follow any normal devaluation, need to be tackled jointly and

up front, as they are likely to be anticipated by agents and markets.

Exit costs can only grow larger if the decision process is protracted and marred by

improvisation and half-baked patches.

Below we briefly discuss why these four issues are an almost inescapable consequence of

leaving the strong currency:

Peso-ification or redenomination of

contractsThe new currency needs to create its own transactional demand and requires a legal

framework that makes it the sole legal tender and unit of account. This requires the forced

redenomination of all contracts in the economy. Regarding prices and wages as well as other

flows of funds the redenomination may not create very serious disruptions.

The redenomination ofaccumulatedstocks, however, particularly those arising from domestic

financial contracts, becomes an extremely thorny issue.

On the one hand, if the new currency succeeds in achieving a real devaluation (i.e.,

this if the pass-through of the nominal devaluation to inflation is reasonably low), the

forced peso-ification of financial contracts results in heavy and asymmetrical balance

sheet effects.

In particular, the losses experienced by domestic euro debtors would more than offset the

gains from a more competitive economy and make the whole euro exit strategy self defeating

(see Frankel 2005).

On the other hand, the peso-ification of bank deposits and credits could have a

massive redistributive impact (benefiting net bank debtors and hurting net deposit

holders) and could bring up violent social and political reactions.

It would also immediately trigger a bank run, as depositors run to protect their savings by

switching them back into hard currency. Indeed a bank run may be unavoidable and precede

the exit, as the Argentine case illustrates.

The Argentinean bank run started in early 2001, nine months before the abandonment of the

currency board arrangement. This is because the mere expectation of an exit is enough to fuel

a deposit run, as well as a credit crunch, in anticipation of the inevitable peso-ification (see

Levy Yeyati et al. 2010).

A deposit freezeTo counter the deposit run and to avoid massive bank failures until the economy is out of thewoods, a temporary deposit freeze would be needed. Crucially, to minimise the damage, the


5/8

freeze needs to be selective, excluding sight and savings deposits needed for everyday

transactions.

Argentina, again, is a good example albeit negative. The gate dropping on all deposit

withdrawals in November 2001 (the so-called corralito) was a misguided choice that caused

a liquidity crunch that only contributed to the downward spiral in economic activity and

market sentiment.

This misguided policy was the immediate cause of the government collapse. By contrast, the

deposit restructuring in January 2002, that peso-ified and froze only term deposits, slowed

down the run thereby preserving the payments system.

Needless to say, these options were (as they always are) desperate measures to cope with a

terminal crisis, and suffered from many shortcomings that are inevitable when policy is made

in a crisis. But even the most careful preparations may not prevent the financial panic

surrounding an anticipated conversion.

An external debt restructuringThis is the flipside of the peso-ification of domestic financial contracts. External debt underinternational law cannot be redenominated by the government but, following the peso-

ification of state revenues and expenditures, it becomes very difficult to service on its original

terms. Therefore international debt relief could come through a negotiated debt exchange.

Importantly, however, such a restructuring is not restricted to the sovereign. Corporate euro

debtors would suffer the same balance-sheet shock and, with the government unable to fund a

bailout, would be forced to renegotiate their liabilities.

In Argentina that was a painful and protracted but essentially successful process. Firms

restructured their debts under the umbrella provided by the combination of sovereign default

and capital controls that inhibited debt servicing abroad. In this way, bankruptcies wereavoided but the access to international markets by the corporate sector remained impaired for

many years. Besides this distinction, however, the main lesson from the Argentine experience

is that it is unrealistic to conceive a euro exit without a debt default.

Capital and exchange-rate controlsEuros (and other reserve currencies) will be precious in the event of a euro exit. Financial

uncertainty fuels capital flight just at the time when the country needs to fund a narrowing but

still sizeable current-account deficit. This scarcity of euros will probably be exacerbated by a

loss of access to international capital markets.

As a result, traditional restrictive measures such as the obligation to surrender export proceedsto the central bank, often coupled with capital outflow and exchange-rate controls, are

necessary. All of these measures were launched in Argentina in early 2002 and contributed to

stabilise the transition.

In fact, it may not be possible to enforce the redenomination of contracts nor the deposit

freeze without capital controls; without them all settlements would immediately move abroad.

Again, the lesson here is that conceiving a euro exit while maintaining full convertibility is

probably wishful thinking.

The euro difference: Harder than acurrency board arrangement


6/8

Argentinas abandonment of its hard peg has some similarities but also marked differences

with the current situation regarding euro exit. Leaving the currency board arrangement was

actually simpler than the introduction of a new currency in that the currency board

arrangement never eliminated the use of the local currency for transaction purposes, the basis

of the demand for money.

In Argentina, the devaluation caught people with pesos in their wallets, and the need forliquidity supported a steady demand for pesos all through the first quarter of 2002 when it

depreciated by 300% (see De la Torre et al. 2003). By contrast, a new drachma or a new

peseta would need to create from scratch a demand for a currency born weaker by design.

Could it work?

Everything is possible but, as noted, there are no real precedents and, just judging from the

costs involved in redistributing wealth through the redenomination of contracts, imposing

bank restrictions, restructuring external debt, and limiting capital mobility, it is certainly not

the easiest way out.

system-wide bank run. Investors, trying to escape, would create a bond-market crisis. Here is

what the train wreck would look like.

The world economy is continually changing, but one constant is dissatisfaction with the euro.

Toward the beginning of the decade, the main complaint was that the euro was too weak forbooming economies like Ireland. Now the complaint is that it is too strong for growth-

challenged countries like Italy.

To be sure, the source of the current problem is external. It stems from the fall of the dollar,

reflecting a combination of economic and financial problems in the United States, and the

insistence of the Chinese authorities that the renminbi should follow the greenback. But that

does nothing to defuse the complaints.

The negative impact is being felt by all euro-area members. But some countries where growth

was already stagnant, such as Italy, are least able to cope. Already in June 2005, following

two years of euro appreciation, then-Italian welfare minister Roberto Maroni declared that

the euro has to go. Then-prime minister Silvio Berlusconi followed by calling the euro adisaster. But this earlier episode of appreciation pales in comparison with what has happened

since. And if the dollar depreciates further and the US falls into a full-blown recession both

of which are more likely than not calls like these will be back.

So is the euro doomed? After seeing the number of euro-area countries rise from 10 in 1999 to

15 at the beginning of 2008, will the process shift into reverse? If one country leaves the euro

area by reintroducing its national currency, will others follow? Will the entire enterprise

collapse?

The answer is no. The decision to join the euro area is effectively irreversible.1 However

attractive the rhetoric of defection is for populist politicians, exit is effectively impossible

although not for the reasons suggested in earlier discussions.A first reason why members will not exit, it is argued, is the economic costs. A country that

leaves the euro area because of problems of competitiveness would be expected to devalue its

newly-reintroduced national currency. But workers would know this, and the resulting wage

inflation would neutralise any benefits in terms of external competitiveness. Moreover, the

country would be forced to pay higher interest rates on its public debt. Those old enough to

recall the high costs of servicing the Italian debt in the 1980s will appreciate that this can be a

serious problem.

But for each such argument about economic costs, there is a counterargument. If

reintroduction of the national currency is accompanied by labour market reform, real wages

will adjust. If exit from the euro area is accompanied by the reform of fiscal institutions so

that investors can look forward to smaller future deficits, there is no reason for interest rates to

go up. Empirical studies show that joining the euro-area does result in a modest reduction in

debt service costs; by implication, leaving would raise them. But this increase could be offset

by a modest institutional reform, say, by increasing the finance ministers fiscal powers from

Portuguese to Austrian levels. Even populist politicians know that abandoning the euro will

not solve all problems. They will want to combine it with structural reforms.

A second reason why members will not exit, it is argued, is the political costs. A country that

reneges on its euro commitments will antagonise its partners. It will not be welcomed at the

table where other European Union-related decisions were made. It will be treated as a second

class member of the EU to the extent that it remains a member at all.

Political costs there would be, but there would also be benefits for politicians who could claim

that they were putting the interests of their domestic constituents first. And politics have not

rendered countries like Denmark and Sweden that have steadfastly refused to adopt the euro

second-class EU member states.

The insurmountable obstacle to exit is neither economic nor political, then, but procedural.

Reintroducing the national currency would require essentially all contracts including those

governing wages, bank deposits, bonds, mortgages, taxes, and most everything else to be

redenominated in the domestic currency. The legislature could pass a law requiring banks,firms, households and governments to redenominate their contracts in this manner. But in a

democracy this decision would have to be preceded by very extensive discussion.

And for it to be executed smoothly, it would have to be accompanied by detailed planning.

Computers will have to be reprogrammed. Vending machines will have to be modified.

Payment machines will have to be serviced to prevent motorists from being trapped in

subterranean parking garages. Notes and coins will have to be positioned around the country.

One need only recall the extensive planning that preceded the introduction of the physical

euro.

Back then, however, there was little reason to expect changes in exchange rates during the

run-up and hence little incentive for currency speculation. In 1998, the founding members ofthe euro-area agreed to lock their exchange rates at the then-prevailing levels. This effectively

ruled out depressing national currencies in order to steal a competitive advantage in the

interval prior to the move to full monetary union in 1999. In contrast, if a participating

member state now decided to leave the euro area, no such precommitment would be possible.

The very motivation for leaving would be to change the parity. And pressure from other

member states would be ineffective by definition.

Market participants would be aware of this fact. Households and firms anticipating that

domestic deposits would be redenominated into the lira, which would then lose value against

the euro, would shift their deposits to other euro-area banks. A system-wide bank run would

follow. Investors anticipating that their claims on the Italian government would beredenominated into lira would shift into claims on other euro-area governments, leading to a

bond-market crisis. If the precipitating factor was parliamentary debate over abandoning the

lira, it would be unlikely that the ECB would provide extensive lender-of-last-resort support.

And if the government was already in a weak fiscal position, it would not be able to borrow to

bail out the banks and buy back its debt. This would be the mother of all financial crises.

What government invested in its own survival would contemplate this option? The

implication is that as soon as discussions of leaving the euro area become serious, it is those

discussions, and not the area itself, that will end.
