Though the 16-nation eurozone sensed relief on Wednesday as Greece announced new austerity measures to reduce its spectacularly unsustainable budget deficit, observers who peek under the eurozone's hood are less than reassured by what they find. Beneath the celebration of Greece's "rescue" lie structural imbalances -- fundamental asymmetries that imperil the euro, the joint currency that has been the centerpiece of European unity since its introduction in 1999.
The key imbalance is between export powerhouse Germany, which generates huge trade surpluses, and its trading partners, which run large trade and budget deficits, particularly Portugal, Italy, Ireland, Greece and Spain.
Those outside of Europe may be surprised to learn that Germany's exports are roughly equal to those of China ($1.2 trillion), even though Germany's population of 82 million is a mere 6% of China's 1.3 billion. Germany and China are the world's top exporters, while the U.S. trails as a distant third.
Dependent on Exports for Growth
Germany's emphasis on exports places it in the so-called mercantilist camp, countries that depend heavily on exports for their growth and profits. Other (nonoil-exporting) nations that routinely generate large trade surpluses include China, Japan, Germany, Taiwan and the Netherlands.
While Germany's exports rose an astonishing 65% from 2000 to 2008, its domestic demand flatlined near zero. Without strong export growth, Germany's economy would have been at a standstill. The Netherlands is also a big exporter (trade surplus of $33 billion) even though its population is relatively tiny, at only 16 million.
The "consumer" countries, on the other hand, run large current-account (trade) deficits and large government deficits. Italy, for instance, has a $55 billion trade deficit and a budget deficit of about $110 billion. Total public debt is a whopping 115.2% of GDP.
Spain, with about half the population of Germany, has a $69 billion annual trade deficit and a staggering $151 billion budget deficit. Fully 23% of the government's budget is borrowed.
Subtle but Devastating Asymmetries
Although the euro was supposed to create efficiencies by removing the costs of multiple currencies, it has had a subtly pernicious disregard for the underlying efficiencies of each eurozone economy.
Though German wages are generous, the German government, industry and labor unions have kept a lid on production costs even as exports leaped. As a result, the cost of labor per unit of output -- the wages required to produce a widget -- rose a mere 5.8% in Germany in the 2000-09 period, while equivalent labor costs in Ireland, Greece, Spain and Italy rose by roughly 30%.
The consequences of these asymmetries in productivity, debt and deficit spending within the eurozone are subtle. In effect, the euro gave mercantilist, efficient Germany a structural competitive advantage by locking the importing nations into a currency that makes German goods cheaper than the importers' domestically produced goods.
Put another way: By holding down production costs and becoming more efficient than its eurozone neighbors, Germany engineered a de facto "devaluation" within the eurozone by lowering the labor-per-unit costs of its goods.
A Derailed Corrective Mechanism
The euro has another deceptively harmful consequence: The currency's overall strength enables debtor nations to rapidly expand their borrowing at low rates of interest. In effect, the euro masks the internal weaknesses of debtor nations running unsustainable deficits and those whose economies had become precariously dependent on the housing bubble (Ireland and Spain) for growth and taxes.
Prior to the euro, whenever overconsumption and overborrowing began hindering an import-dependent "consumer" economy, the imbalance was corrected by an adjustment in the value of the nation's currency. This currency devaluation would restore the supply-demand and credit-debt balances between mercantilist and consumer nations.
Absent the euro today, the Greek drachma would fall in value versus the German mark, effectively raising the cost of German goods to Greeks, who would then buy fewer German products. Greece's trade deficit would shrink, and lenders would demand higher rates for Greek government bonds, effectively pressuring the government to reduce its borrowing and deficit spending.
But now, with all 16 nations locked into a single currency, devaluing currencies to enable a new equilibrium is impossible. And it leaves Germany facing with the unenviable task of bailing out its "customer nations" -- the same ones that exploited the euro's strength to overborrow and overconsume. On the other side, residents of Greece, Italy, Spain, Portugal and Ireland now face the unenviable effects of government benefit cuts aimed at realigning budgets with the productivity of the underlying national economy.
While the media has reported the Greek austerity plan and EU promises of assistance as a "fix," it's clear that the existing deep structural imbalances cannot be resolved with such Band-Aids.
The diagram below outlines this structural dynamic: Either Germany and its export-surplus neighbors continue bailing out the eurozone's importer/debtor consumer nations, or eventually the weaker nations will default or slide into insolvency.
Germany helped enable the overborrowing of its profligate neighbors by buying their government bonds. According to BusinessWeek, German banks are on the hook for almost $250 billion in the troubled eurozone nations' bonds.
Now a vicious conundrum has emerged: If Germany lets its weaker neighbors default on their sovereign debt, the euro will be harmed, and German exports within Europe will slide. But if Germany becomes the "lender of last resort," then its taxpayers end up footing the bill.
If public and private debt in the troubled nations keeps rising at current rates, it's possible that even mighty Germany may be unable (or unwilling) to fund an essentially endless bailout. That would create pressure within both Germany and the debtor nations to jettison the single currency as a good idea in theory, but ultimately unworkable in a 16-nation bloc as diverse as the eurozone.
