Europe’s Emerging Bubbles

by Hans-Werner Sinn

Hans-Werner Sinn, Professor of Economics at the University of Munich, was President of the Ifo Institute for Economic Research and serves on the German economy ministry’s Advisory Council.


MUNICH – The European Central Bank’s latest policy moves have shocked many observers. While the goal – to prevent deflation and spur growth – is clear, the policies themselves are setting the stage for severe instability.

The policies in question include setting the interest rate on the ECB’s main refinancing operations to zero; raising monthly asset purchases by €20 billion ($22.3 billion) to €80 billion; and pushing the interest rate on money that banks deposit with the ECB further into negative territory – to -0.40%. Moreover, the ECB has launched a new series of four targeted longer-term refinancing operations, which also carry negative interest rates. Banks receive up to 0.4% interest on ECB credit that they take themselves, provided they lend it out to private businesses.

These policies are, in essence, the latest in a string of attempts by the ECB to address the fallout of the collapse of the massive bubble that formed in southern Europe in the early years of the euro. It all began with the announcement of the euro’s introduction at the 1995 EU Summit in Madrid, which caused interest rates to tumble.

The inflationary credit bubble spurred in southern European countries by the persistence of lower interest rates undermined their competitiveness and drove asset and property prices to unsustainably high levels. When the bubble burst, the ECB tried to prevent the excessive prices from returning to their equilibrium levels by using its printing press and promising unlimited coverage to investors. The latest ECB measures are just more of the same.

Of course, when the financial crisis erupted in full force in 2008, following the collapse of the US investment bank Lehman Brothers, the ECB’s interventions were justified. But after the global economy started to recover during the latter part of the following year, the ECB’s moves became increasingly problematic, because they enabled countries to evade structural reform and hindered the necessary disinflation in the southern eurozone countries – or even halted it altogether, as in Portugal and Italy.

Southern Europe had succumbed to the drug of cheap credit. But when private credit stalled and the symptoms of withdrawal began to appear, the ECB provided replacement drugs. Instead of treating the addiction, it created junkie economies that were unable to function without a fix.

Japan made a similar mistake when its property bubble burst in 1990. For over two decades, the Bank of Japan flooded the economy with money at near-zero interest rates. The Japanese government, for its part, has followed such a relentless policy of deficit spending that public debt jumped from 67% of GDP to 246% of GDP today, with the latest upward push provided by the dubious “Abenomics” economic strategy being pursued by Prime Minister Shinzo Abe’s government.

None of this has helped, because neither monetary nor fiscal policy can substitute for structural reform. On the contrary, the more Keynesian and monetarist drugs are administered, the feebler the self-healing power of the markets and the weaker the willingness of policymakers to impose painful detoxification treatments on the economy and populace.

But the worst effects of the ECB policy may be yet to come, if the eurozone’s still-sound economies also become credit junkies. There are already some worrying signs of this. Property markets in Austria, Germany, and Luxembourg have practically exploded throughout the crisis, as a result of banks chasing borrowers with offers of loans at near-zero interest rates, regardless of their creditworthiness. In Austria, property prices have risen by nearly half since the Lehman collapse; in Luxembourg, they have risen by almost one-third.

Even Germany, Europe’s largest economy, has been experiencing a massive property boom since 2010, with average urban property prices having risen by more than one-third – and by nearly half in large cities. The country is undergoing a construction boom not seen since reunification. Real estate agents have only leftovers on offer.

The German property boom could be reined in with an appropriate jump in interest rates. But, given the ECB’s apparent determination to head in the opposite direction, the bubble will only grow. If it bursts, the effects could be dire for the euro; the new Euro-skeptic Alternative for Germany party, which made astonishing headway in the country’s recent state elections, would make sure of that.

The cabinet members who resigned this week apparently feared that politics is taking May toward a “soft Brexit,” their worst of all possible worlds........“soft Brexit,” maintains the status quo, more or less, letting Europeans freely circulate into British labor markets and allowing European firms to operate easily in the UK. The problem with “soft Brexit” is that it raises questions about why the UK is leaving at all, since it will still have the same obligations to Europe as before, it just won’t have a voice when the remaining 27 members of the European Union meet to make decisions.

One study on the 2010 World Cup found that there was a 37.5% rise in admission rates across 15 accident and emergency departments on England match days........Examining reports of domestic abuse in Lancashire (a county of approximately 1.5m people in Northern England), across the 2002, 2006 and 2010 World Cup tournaments, we discovered a 26% increase in reports of domestic abuse when England won or drew, and a 38% increase when England lost. Reports were also more frequent on weekends, and reached their peak when England exited the tournament.

If, back in the 1980s and 1990s, the US government, rather than arguing for Chinese economic opening, had prohibited any US company from investing there, China’s rise would have been significantly delayed, though not permanently prevented. Because that did not happen, China’s rise is now self-sustaining. A huge and increasingly affluent domestic market will make exports less vital to growth.

Comparing today’s demagogues with Adolf Hitler is almost always unwise. Such alarmism tends to trivialize the actual horrors of the Nazi regime, and distracts attention from our own political problems. But if alarmism is counterproductive, the question remains: At what point are democracies truly in danger? What was unimaginable only a few years ago – a US president insulting democratic allies and praising dictators, or calling the free press “enemies of the people,” or locking up refugees and taking away their children – has become almost normal now. When will it be too late to sound the alarm?

In view of such actions, expectations for Trump’s behavior at the upcoming summit have gone from prickly to dangerous. The sense of foreboding has been heightened by the announcement that, just four days after the summit ends, Trump will meet with Russian President Vladimir Putin, in Helsinki. The nightmare scenario is easy to imagine: Trump lays bare NATO’s fractures, including by questioning mutual defense, before selling his allies down the river by publicly embracing Putin. But this does not need to be the outcome.

After 2027 (or maybe even 2025, only 7 years from now), the number of EVs will rapidly accelerate, as virtually all new vehicles bought will be electric (an effect of rapidly falling battery and other component costs and of the fuel for electric cars being essentially free; you can power one off your rooftop solar array).

Most pundits interpret Trump’s outbursts as playing to his political base, or preening for the cameras, or blustering for the sake of striking future deals. We take a different view. In line with many of America’s renowned mental-health experts, we believe that Trump suffers from several psychological pathologies that render him a clear and present danger to the world.

In the United Kingdom, Brexit looms large, with everyone from government ministers to tabloid newspapers frothing daily about the deal that will be struck with the European Union and the effects that it will have. But the EU faces too many pressing challenges to be obsessing about Britain. The UK’s concern is understandable: evidence is mounting of the likely damage a departure from the single market and customs union will do to the UK economy. According to new research from the Centre for European Reform, the UK economy is already 2.1% smaller than it would have been had voters chosen to remain. The hit to public finances totals £440 million ($579 million) per week.

Nowadays, Britain’s words and actions on the world stage are so at odds with its values that one must wonder what has happened to the country. Since the June 2016 Brexit referendum, British foreign policy seems to have all but collapsed – and even to have disowned its past and its governing ideas. Worse, this has coincided with the emergence of US President Donald Trump’s erratic administration, which is pursuing goals that are completely detached from those of Britain – and of Europe generally.

With each passing day, it becomes increasingly evident that US President Donald Trump’s administration cares less about economics and more about the aggressive exercise of political power. This is obviously a source of enormous frustration for those of us who practice the art and science of economics. But by now, the verdict is self-evident: Trump and his team continue to flaunt virtually every principle of conventional economics.

The sights and sounds of Central American children being ripped from their parents by US Border Patrol officers have, by now, spread across the globe. The experience has been traumatizing to its victims and deeply painful to watch. It has also done incalculable damage to the very idea of America. This is June when we are supposed to be celebrating "Immigrant Heritage Month". Each year, I have taken this opportunity to recall my family's immigrant story - the opportunity and freedom they sought, the hardships they endured, and the remarkable progress they made in just one generation.

State terrorism comes in many forms, but one of its most cruel and revolting expressions is when it is aimed at children. Even though U.S. President Donald Trump backed down in the face of a scathing political and public outcry and ended his administration’s policy of separating migrant children from their parents, make no mistake: His actions were and remain a form of terrorism.

It is now clear that the twenty-first century is ushering in a new world order. As uncertainty and instability associated with that process spread around the globe, the West has responded with either timidity or nostalgia for older forms of nationalism that failed in the past and certainly will not work now. Even to the most inveterate optimist, the G7 summit in Quebec earlier this month was proof that the geopolitical West is breaking up and losing its global significance, and that the great destroyer of that American-created and American-led order is none other than the US president. To be sure, Donald Trump is more a symptom than a cause of the West’s disintegration. But he is accelerating the process dramatically.

Sessions quoted a line written by the apostle Paul to a small community of Christians living in Rome around 55AD to defend the Department of Justice’s approach. He said: "I would cite you to the Apostle Paul and his clear and wise command in Romans 13, to obey the laws of the government because God has ordained them for the purpose of order." Sessions used the Bible because one of the most vocal opponents of the crackdown on asylum cases has been the Catholic Church. It’s no surprise that Sessions appealed to Romans chapter 13 verse 1 in response: not only did he hope to undermine Catholic authority by using the Bible against them, he cited a statement so broad that one might use it to defend anything a government does, good or bad.

Extract: PiS [ the ruling Law and Justice party] has established the most significant addition to the Polish social safety net since 1989: the Family 500+ program. Launched in 2016, Family 500+ embodies the nationalism, traditional family values, and social consciousness that the PiS seeks to promote. The program pays families 500 złoty ($144) per month to provide care for a second or subsequent child...........The program has been enormously popular. Some 2.4 million families took advantage of it in the first two years. The benefit, equivalent to 40% of the minimum wage, has almost wiped out extreme poverty for children in Poland, reducing it by an estimated 70-80%........... Liberal pro-European politicians and policymakers are not convinced. They complain that such a generous family benefit will weaken work incentives and blow up the government budget. But initial evidence suggests that Family 500+ has actually increased economic activity. It has also reversed the post-communist decline in fertility, increased wages (particularly for women), and enabled families to buy school materials, take vacations, buy more clothes for their kids, and rely less on high-priced credit for basic household needs. And, thanks to rapid economic growth, the government deficit has steadily fallen, not grown.

The depths of hypocrisy of the Republican Party in supporting Trump’s meeting with the North Korean dictator in Singapore are hard to plumb.

US Defense Secretary Jim Mattis has spoken out against China’s strategy of “intimidation and coercion” in the South China Sea, including the deployment of anti-ship missiles, surface-to-air missiles, and electronic jammers, and, more recently, the landing of nuclear-capable bomber aircraft at Woody Island. There are, Mattis warned, “consequences to China ignoring the international community.” But what consequences?

With a general election approaching in September, Swedish voters are being warned that now it’s their turn to be targeted by Russian interference in the democratic process.
