1
Origin of “Currency Wars,” Fall 2010

Warning from Brazil’s Finance
Minister Guido Mantega (9/27/2010):
“We’re in the midst of
an international currency war,
a general weakening of currency. This threatens us
because it takes away our competitiveness.”

I.e., countries everywhere are trying
to push down the value of their currencies,
to gain exports & employment,
• a goal that is not globally consistent.
2
Currency Wars, Fall 2010

Two advanced countries had recently
fought strong appreciations of
their currencies by selling
them in forex intervention:
• Japan
• Switzerland
3
Currency Wars chronology,

continued
Renewed flows to emerging markets in 2010
had met with $ purchases in FX intervention
•
•
•
•
•
Brazil,
Korea,
Thailand,
Peru …
By 2011, even Chile, the cleanest of the floaters,
was intervening to dampen appreciation.
4
Currency Wars,

China had long been intervening
to prevent the RMB from appreciating.


continued
The U.S. tried to enlist help from countries like Brazil
in pressuring China to abandon its undervaluation.
The Brazilian Minister’s response:
The $ is as much a part of the problem as the RMB.
• He was referring to QE2 that fall, which like any other
monetary easing could be expected to depreciate the $.

More attacks on Fed action -• China & Germany: $ depreciation is a deliberate salvo in currency wars
• Sarah Palin, Rick Perry & John Taylor: QE2 “debauches the currency.”
5
Today, in 2012,
Currency Wars look different

As in a real war:
• at first it seems to be about boldness,
clever strategic moves, & strength of will.
• In practice, wars often turn out less uplifting:
 You are shooting yourself in the foot.

Who is screwing up its debt crisis worse:
Europe or the US?
It’s a tough call
-- US News & World Report, 11/07/2011

On the one hand,
Europe is much closer to full-fledged crisis.
Debt problems in Mediterranean members:
• are insoluble at current interest rates,
• are pushing Europe back into recession, and
• could well result in one or more countries forced to leave the euro.
By contrast, there is no true fiscal crisis in US yet;
the world’s investors are still buying
lots of US bonds at low interest rates.
7
Who is screwing up its debt crisis worse:
Europe or the US? – continued

On the other hand, mistakes by US politicians are
more gratuitously self-inflicted than across the Atlantic.
• In 2001, all we had to do was continue the 1990s’ fiscal progress:

preserve the budget surplus and move on to address the longer term
problems of social security & Medicare in a deliberate balanced manner.
• Instead we recklessly enacted huge tax cuts and tripled federal spending growth,
in ways guaranteed to generate serious fiscal troubles ten years into the future.
• The debt-ceiling standoff, summer 2011,
was but the latest self-inflicted wound,


new evidence that the American political system was not functioning,
which led to the US credit rating downgrade.
8
Greece & the Euro Crisis:
Seven Mistakes


7 mistakes made by euroland’s leaders
regarding Greece
Slender rays of hope:
• The hour of the technocrats
• Proposals for the future
10
3 mistakes made by euro architects
before the crisis

Admitting Greece to the € in the first place,
• and other countries that were not yet ready -• neither by traditional Optimum Area Currency criteria
incl. cyclical correlation & labor mobility,
• nor by Maastricht criteria,
 esp. fiscal criteria:
 BD < 3% of GDP & Debt < 60% of GDP.


Pretending after 1999 to enforce the fiscal criteria

via the Stability & Growth Pact.


Allowing Mediterranean countries’ bonds spreads ≈ 0,
• helped by investors’ under-perception of risk (2003-07)
• and artificial high credit ratings. But also by
• ECB acceptance of Greek bonds as collateral.
11
The Treaty of Maastricht (1991) surprised many
economists by emphasizing fiscal criteria
as qualifications for membership.
Why did the designers do it?

Theory I: Jason
& the Golden Fleece

Theory II: Theseus
& the stone

Theory III: Odysseus
& the mast.
Frankel, Economic Policy (London) 16, April 1993, 92-97.
12
The motivation for the Maastricht fiscal criteria


was the same as for the No Bailout Clause
and the Stability & Growth Pact (1997):

Skeptical German taxpayers believed that, before
the € was done, they would be asked to bail out
profligate Mediterranean countries.

European elites adopted the fiscal rules to
demonstrate that these fears were groundless.
13
After the euro came into existence

it became clear the German taxpayers had been right
• and the European elites were wrong.

E.g., Greece persistently violated the 3% deficit rule.

The large countries violated the rule too.

SGP targets were “met” by overly optimistic forecasts.

SGP threats of penalty had zero credibility.

Yet each year the ostrich elites stuck
their heads deeper & deeper into the sands.
14
The Greek budget deficit
never got below the 3% of GDP limit,
nor did the debt ever decline toward the 60% limit
15
Yet spreads for Italy, Greece, & other Mediterranean
members of € were near zero, from 2001 until 2008.
16
Market Nighshift Nov. 16, 2011
When PASOK leader George Papandreou
became PM in Oct. 2009,

he announced
• that “foul play” had misstated the fiscal statistics
under the previous government:
• the 2009 budget deficit ≠ 3.7%,
as previously claimed,
but > 12.7 % !
17
Missed opportunity

The EMU elites had to know that someday
a member country would face a debt crisis.

In early 2010 they should have viewed Greece as a good
opportunity to set a precedent for moral hazard:
• The fault egregiously lay with Greece itself.

Unlike Ireland or Spain, which had done much right.
• It is small enough that the damage from debt restructuring could
have been contained at that time.

They should have applied the familiar IMF formula:
serious bailout, but only conditional on serious
policy reforms & Private Sector Involvement.
18

But the ostriches
stuck their heads
ever further down
in the sand.
Mistakes #4 & #5: when the crisis hit,
leaders buried their heads in the sand:
• 2 years ago,
sending Greece to the IMF was “unthinkable.”
• 1 year ago,
restructuring the debt was “unthinkable.”
19
What is wrong with the current debate?



Mistake #6:
6a: Talking as if a “big bazooka” bailout
alone can solve the problem. Or
6b: Talking as if austerity
alone can solve the problem,
• which is related to the belief in some places
that fiscal contraction is expansionary.


Republican politicians say it, but (from their actions) don’t
appear actually to believe it.
UK politicians appear actually to believe it.
• & some other Europeans.
20
Any solution to the euro crisis must include a
way to prevent repeats in the long term.

German taxpayers are no more
supportive of a “transfer union” than ever.

This means finding a way to prevent moral hazard
• as the Maastricht architects knew all along -

preventing individual countries from running big deficits & debts,
expecting to be bailed out in the event of a crisis.
Merkel’s “fiscal compact” is the 7th mistake:
• yet another declaration of determination
to strengthen the SGP,
• incl. via budget limits
in national laws/constitutions.
Perhaps the Fiscal Compact
misunderstands the US system

Yes, despite a common currency,
the 50 states do not have moral hazard:
• the federal government has never bailed one out,

and nobody expects it to do so now.
• But that is not because of the budget rules
that (49 of) the states have.


Their rules are voluntary, varied, and flexible.
Some states do have debt troubles,
• and even default.
How the US avoids moral hazard
in the 50 states

The principle was established in 1840 when the federal government
refused to save 8 states from default.

Government spending at the state level is a far smaller share of
income than at the federal level,
• let alone on the part of European states.
• Is Europe ready for that? No.

When one state begins to run its debt too high,
the private market automatically
imposes an interest rate penalty.
• E.g., California today.
• Gives states the incentives to get back in line.
• This mechanism conspicuously failed from the euro’s 1st day.
• which showed that moral hazard had not been addressed.
Slender rays of hope, #1

Greece, Ireland & Portugal did finally go to the IMF;
Germany & banks did finally agree to write down Greek debt.
• But it has always been much too little, too late.

The only solution for the short-term:
• more money

from ECB & national governments, perhaps via IMF
• conditional on reforms + PSI, country-by-country.
24
Slender rays of hope, #2:
The Hour of the Technocrats

A government of technocrats under Mario Monti
in Italy is a huge improvement
over the disaster of Berlusconi.

Similarly Lucas Papademos in Greece
• But he has been given even less freedom of
action than Monti: his term is very short
and he wasn’t allowed to pick his cabinet.
25
Mario Draghi became
President of the ECB, Nov.1, 2011

He was under intense pressure to expand his predecessor’s purchases
of large quantities of periphery-country bonds.
• The ECB was urged to be the “big bazooka”:

to play the role of “lender of last resort,” an abuse of that term,
• which is supposed to refer to back-stopping banks, not countries.
• If the ECB interpreted its mandate literally,
as no more than keeping inflation low,
then the euro might break up.

On the other hand, as Draghi knew:
• the ECB is legally prohibited from financing governments directly.
• If he had quickly bailed out Italy & the others, he would have:
 facilitated a continuation of Berlusconi-style irresponsibility;
 been immediately written off by Germans as another profligate Italian.
So far, Draghi’s LTRO (Longer-Term Refinancing
Operation) has been a brilliant success.

On Dec. 22, he caught everyone
by surprise by the clever ploy
of doing exactly what he had
previously announced he would do:
• loans to banks for 3 years, at low interest.
 High take-up: € 489 b, 523 banks
• especially in troubled countries.
• No stigma.
• Brought down interbank spreads & country spreads,

while consistent with central bank LoLR mandate.
2nd LTRO, February 29

Some 800 banks took up €530 b of loans
at the 2nd round on Wednesday,
• borrowing at 1% for 3 years

with almost any form of collateral.
• Citigroup: = €316 b of fresh liquidity,
 stripping out renewal of old loans.


Vs. €200 b in extra stimulus at the 1st LTRO
Totalling $1 trillion.
28
My guess

Greece will make it past March 20,
• with usual 3-part formula of bail-out + conditionality + PSI ;

but then will default within a year.
• Greece cannot get back to a sustainable debt path
by austerity, as has been clear for awhile.
• When it succeeds in eliminating its primary budget deficit,
it will have no more incentive to keep servicing debt.

Possibly Portugal as well.
Silver linings of procrastination?

By then, Greece (& Italy et al) may finally have made
some of the structural reforms they need,



such as opening up professions ,
which can only be done under pressure.
Perhaps EU banks, including those that have written CDSs,
will have used the time to provision
• making themselves less vulnerable to default.

Analogy would then be to the international debt crisis of 1982:
International creditor banks used the lost decade to reduce exposure,
• until they were able to mark to market in 1989 (Brady plan).

But I agree with the Macquarie paper on European Banks (Jan. 25)
that a better analogy may be Japan’s lost “decade,” 1990-2003,
when “prolonging the crisis to give banks time to solve the problems
‘inevitably raised the cost of the final resolution [IMF, 2000] ’.”
30
Risk of contagion is high
not just to rest of euro periphery, but to rest of world.
• The outlook
• The U.S. recovery, though weak,
has become more fully established.
• Who is vulnerable?

U.S. economic news so far in 2012
has been better than 2011

Recent statistics:
• Unemployment has declined to 8.3%
• Growth in Q4 2011 revised up to 3.0%


(2/29/12) from 2.8 %
Blue Chip Economic Indicators survey (February)
consensus forecast for 2012 GDP growth:
Q1 = 2.1 %, Q2 = 2.2 %, Q3 = 2.4 % , Q4 = 2.6 %.
Bernanke’s testimony (2/29/12) was interpreted negatively.
• GDP growth in the next few quarters "at a pace close to or
somewhat above" the 2 ¼ % seen in the 2nd half of 2011.


Estimates by members of the FOMC range from 2.2 to 2.7,
in the new communications strategy for more transparency.

Possible risks to the scenario in 2012

Euroland: Worsening of sovereign debt crisis
• and contagion overseas.

US
• new debt ceiling standoff

Emerging markets: hard landing
• particularly in China.

Major oil crisis
• from military confrontation with Iran.

Sovereign debt worries
...
•
• Who is vulnerable?
• The emerging market countries are
in much better shape than past decades,
• in an amazing & historic role reversal.
39
A remarkable role-reversal:
• Debt/GDP of the top 20 rich countries
(> 80%) is already more than twice
that of the top 20 emerging markets;
• and rising rapidly.
• Nor are the EMs necessarily less
“debt tolerant” for a given debt/GDP
• as Reinhart & Rogoff thought not long ago.

What Determines Country Vulnerability?

Fundamentally: Quality of institutions.
• This does not mean “tough” rules –
like SGP, debt ceiling or BBA – which lack enforceability.
• Better would be structural budget targets (Swiss)
with forecasts from independent experts (Chile).
• One third of developing countries since 2000 have graduated from
pro-cyclical spending to countercyclical,
• even while US, UK & euro countries have forgotten
how to run countercyclical fiscal policy,

and instead enact fiscal expansion in booms
& contraction after recessions.

In the last decade,
about 1/3 developing countries
switched to countercyclical fiscal policy:
Negative correlation of G & GDP.
It’s not so much the level
of debt/GDP that matters

as the risk of getting stuck on an explosive path,
with ever-rising debt/GDP
• because of high primary deficit or interest rates
(or low growth), or risk of a sudden deterioration.

Early Warning indicators:
• composition of capital inflows

Fx-denominated, ST, bank loans vs.
FDI, equity & contracts with automatic adjustment provisions.
• Plus real currency overvaluation, fx reserves (for peggers)…
• Fiscal capacity.
Early Warning Indicators: Reserves

When the 2008-09 global financial crisis hit,
• those countries that had taken advantage of
the 2003-08 boom to build up reserves did better.

New lesson regarding exchange rate regimes

Old conventional wisdom: The choice was between
• fixing (changes in reserves; not in exchange rate) vs.
• floating (changes in exchange rate; no reserves).

Now it appears that:
• Intermediate regimes are indeed viable.
• Holding reserves
and floating are both useful.

World Bank forecasts


The World Bank has downgraded economic forecasts for
developing countries in its 2012 Global Economic Prospects.
E.g., Brazil’s annual GDP growth, which came to a halt in the 3rd
quarter of 2011, is forecast to reach 3.4% in 2012,
• < half the 7.5% rate in 2010.

Reflecting a sharp slowdown in the second half of the year in
India, South Asia is slowing from a torrid six years,
• which included 9.1% growth in 2010.
• Regional growth is projected to decelerate further, to 5.8%, in 2012.

The biblical cycle


Joseph prophesied 7 years of plenty,
with abundant harvests from a full Nile
-- followed by 7 lean years of drought & famine.
The Pharaoh empowered his technocratic official
(Joseph) to save grain in the 7 years of plenty,
• building up sufficient stockpiles to save the Egyptian people
from starvation during the bad years.
• -- a valuable lesson for today’s government officials
in industrialized & developing countries alike.
52
Biblical cycle, cont.

For emerging markets, the first phase of 7 years
of plentiful capital flows occurred in 1975-1981,
• recycling petrodollars as loans to developing countries.
• The international debt crisis that began in Mexico in 1982
was the catalyst for the 7 lean years,

known in Latin America as the “lost decade.”
• The turnaround year, 1989, saw the first issue of Brady
bonds, which helped write down the debt overhang

and put a line under the crisis.
53
Biblical cycle, cont.

The second cycle of 7 fat years was the period of
record capital flows to emerging markets in 199096.
• Following the 1997 “sudden stop” in East Asia came 7
years of capital drought.

The third cycle of inflows, often identified as a “carry
trade,” came in 2004-2011
• and persisted even through the global financial crisis.

If history repeats itself, it is now time for a third
sudden stop of capital flows to emerging markets.
54
Are emerging markets due for a correction,
triggered by a new wave of “risk off” behavior?

China could land hard as its real-estate bubble deflates
and the country’s banks are forced to work off bad loans.

High GDP growth rates in Brazil & Argentina
over the same period could reverse,
• particularly if global commodity prices fall –


Esp. if the Chinese economy begins to falter.
Most worrisome: Europe’s woes
could spread to neighbors such as Turkey.
• Turkey can probably not sustain the rapid economic growth
and very high trade deficits of recent years.
• Vulnerable to world oil price.
• Also, recent domestic politics may put off investors.
