The Liquidity Time Bomb

by Nouriel Roubini

NEW YORK – A paradox has emerged in the financial markets of the advanced economies since the 2008 global financial crisis. Unconventional monetary policies have created a massive overhang of liquidity. But a series of recent shocks suggests that macro liquidity has become linked with severe market illiquidity.

Policy interest rates are near zero (and sometimes below it) in most advanced economies, and the monetary base (money created by central banks in the form of cash and liquid commercial-bank reserves) has soared – doubling, tripling, and, in the United States, quadrupling relative to the pre-crisis period. This has kept short- and long-term interest rates low (and even negative in some cases, such as Europe and Japan), reduced the volatility of bond markets, and lifted many asset prices (including equities, real estate, and fixed-income private- and public-sector bonds).

And yet investors have reason to be concerned. Their fears started with the “flash crash” of May 2010, when, in a matter of 30 minutes, major US stock indices fell by almost 10%, before recovering rapidly. Then came the “taper tantrum” in the spring of 2013, when US long-term interest rates shot up by 100 basis points after then-Fed Chairman Ben Bernanke hinted at an end to the Fed’s monthly purchases of long-term securities.

Likewise, in October 2014, US Treasury yields plummeted by almost 40 basis points in minutes, which statisticians argue should occur only once in three billion years. The latest episode came just last month, when, in the space of a few days, ten-year German bond yields went from five basis points to almost 80.

These events have fueled fears that, even very deep and liquid markets – such as US stocks and government bonds in the US and Germany – may not be liquid enough. So what accounts for the combination of macro liquidity and market illiquidity?

For starters, in equity markets, high-frequency traders (HFTs), who use algorithmic computer programs to follow market trends, account for a larger share of transactions. This creates, no surprise, herding behavior. Indeed, trading in the US nowadays is concentrated at the beginning and the last hour of the trading day, when HFTs are most active; for the rest of the day, markets are illiquid, with few transactions.

A second cause lies in the fact that fixed-income assets – such as government, corporate, and emerging-market bonds – are not traded in more liquid exchanges, as stocks are. Instead, they are traded mostly over the counter in illiquid markets.

Third, not only is fixed income more illiquid, but now most of these instruments – which have grown enormously in number, owing to the mushrooming issuance of private and public debts before and after the financial crisis – are held in open-ended funds that allow investors to exit overnight. Imagine a bank that invests in illiquid assets but allows depositors to redeem their cash overnight: if a run on these funds occurs, the need to sell the illiquid assets can push their price very low very fast, in what is effectively a fire sale.

Fourth, before the 2008 crisis, banks were market makers in fixed-income instruments. They held large inventories of these assets, thus providing liquidity and smoothing excess price volatility. But, with new regulations punishing such trading (via higher capital charges), banks and other financial institutions have reduced their market-making activity. So, in times of surprise that move bond prices and yields, the banks are not present to act as stabilizers.

In short, though central banks’ creation of macro liquidity may keep bond yields low and reduce volatility, it has also led to crowded trades (herding on market trends, exacerbated by HFTs) and more investment in illiquid bond funds, while tighter regulation means that market makers are missing in action.

As a result, when surprises occur – for example, the Fed signals an earlier-than-expected exit from zero interest rates, oil prices spike, or eurozone growth starts to pick up – the re-rating of stocks and especially bonds can be abrupt and dramatic: everyone caught in the same crowded trades needs to get out fast. Herding in the opposite direction occurs, but, because many investments are in illiquid funds and the traditional market makers who smoothed volatility are nowhere to be found, the sellers are forced into fire sales.

This combination of macro liquidity and market illiquidity is a time bomb. So far, it has led only to volatile flash crashes and sudden changes in bond yields and stock prices. But, over time, the longer central banks create liquidity to suppress short-run volatility, the more they will feed price bubbles in equity, bond, and other asset markets. As more investors pile into overvalued, increasingly illiquid assets – such as bonds – the risk of a long-term crash increases.

This is the paradoxical result of the policy response to the financial crisis. Macro liquidity is feeding booms and bubbles; but market illiquidity will eventually trigger a bust and collapse.

Waging a war against Iran, or even thinking of doing so, is sheer madness. Trump has thus far wisely rejected the warmonger National Security Advisor John Bolton’s outrageous advice. Waging another war in the Mideast, this time against Iran, would have not only disastrous consequences for the US but will also engulf our allies from which they would suffer incalculable human losses and destruction. Bolton was the architect behind the devastating war in Iraq in 2003, which inflicted more than 5,000 US casualties and a cost exceeding two trillion dollars, allowed Iran to entrench itself in Iraq, and gave way to the rise of ISIS.

The private Tasnim news agency reports from Iran that in a speech to thousands of university students, Iran’s clerical leader Ali Khamenei made an unusual and extraordinary criticism of president Hassan Rouhani and foreign minister Mohammad Javad Zarif over their handling of the 2015 Joint Comprehensive Plan of Action or deal on limiting Iran’s nuclear enrichment program.

Extract: "Brexit, after all, is as much a Kremlin project as it is anyone else’s. Putin wants to divide Europeans, and in the UK, Brexit has succeeded in dividing Britons like nothing since the Corn Law debates almost 200 years ago. Putin wants the EU to fragment, and Brexit is causing the biggest crack yet in the bloc’s history. Putin wants to sow doubt about the legitimacy of traditional news sources; pro-Brexit media consistently promote lies as truth and inveigh against reputable papers like the Financial Times as elitist enemies of the people."

Iraq’s population when invaded was 26 million. Iran’s population today is 81 million..........Whereas Iraq’s neighbors– Turkey, Iran and Saudi Arabia in particular– had been mauled by Saddam and so did not strongly oppose Bush’s invasion, Shiite Iraqis, many Syrians, the Hazaras of Afghanistan, and the some 40 million Shiites of Pakistan would support Iran.

It’s time that economists, pundits, and politicians start looking holistically at life in our times, and take seriously the long-term structural changes needed to address the multiple crises of health care, despair, inequality, and stress in the US and many other countries. US citizens, in particular, should reflect on the fact that many other countries’ people are happier and less worried, and are living longer. In general, those other countries’ governments are not cutting taxes for the rich and slashing services for the rest. They are attending to the common good, instead of catering to the rich while pointing to illusory economic statistics that hide as much as they reveal.

"........Meanwhile, Trump is leaving the door open for Russia to come to his aid again in 2020. The White House and congressional Republican leaders have been blocking a bill to secure US elections against foreign attacks. And administration officials have been instructed not to raise the issue of Russian interference with the president, lest it cast a shadow on his legitimacy.  The next phase in this affair is already coming into focus. Barr, with the help of Trump’s golfing buddy Lindsey Graham, the Republican chair of the Senate Judiciary Committee, is now enlisted in peddling the president’s fantasy that the Mueller investigation was a “witch hunt” orchestrated by “deep-state” supporters of Hillary Clinton. Once again, current and former FBI agents will be targeted, either because they expressed criticism of Trump or because they opened a national security investigation into a hostile power’s meddling in the US presidential election (which continued in the 2018 midterms). FBI director Christopher Wray, commenting on the Mueller report, said that the Russians are “upping their game” for 2020. "

Accusing Iran of being a rogue country bent on acquiring nuclear weapons, supporting extremist groups and terrorism, persistently threatening Israel, and destabilizing the region in its relentless effort to become the dominant power may well all be justified. The question is, what would it take to stop Iran from its destabilizing activities and help make it a constructive member of the international community, and avoid military confrontation with either the US or Israel or both?

Some of the most famous scientific discoveries happened by accident. From Teflon and the microwave oven to penicillin, scientists trying to solve a problem sometimes find unexpected things. This is exactly how we created phosphorene nanoribbons – a material made from one of the universe’s basic building blocks, but that has the potential to revolutionise a wide range of technologies.

Easter visitors to London have found some streets and buildings occupied by “Extinction Rebellion” activists, warning of climate catastrophe and rejecting “a failed capitalist system.” Followers of central bank thinking have seen the governors of the Bank of England and Banque de France warning that climate-related risks threaten company profits and financial stability. Both interventions highlight the severity of the climate challenge that the world faces. But warnings alone won’t fix the problem unless governments set ambitious but realistic targets to eliminate carbon dioxide and other greenhouse-gas emissions, backed by policies to ensure the targets are achieved. Zero net CO2 emissions by 2050 at the latest should be the legally defined objective in all developed economies.

LONDON – Russian efforts to influence European elections have received plenty of media attention. But the same cannot be said of interference by conservative Christian groups based in the United States, some with links to President Donald Trump’s administration and his former adviser, Stephen Bannon.

On the night of April 15, 2019, in Paris, the emotions were raw. “Notre Dame is burning, the whole of France is crying, the whole world is crying,” said Archbishop Michel Aupetit of Paris. “It’s terrible, frightening, painful, a tragedy, a nightmare.” “This place leaves no one untouched. When you enter this cathedral, it inhabits you,” said Anne Hidalgo, the Mayor of Paris, in front of the burning monument. “We will rebuild,” said the Rector of Notre Dame, “we will rebuild.”

High-level political purges are gathering pace in Russia. The latest evidence came in late March, with the arrests of Mikhail Abyzov, a former minister for open government affairs, and – two days later – Viktor Ishayev, a former Far East minister and ex-governor of Russia’s Khabarovsk region. Unsurprisingly, the arrests of such senior figures is having a chilling effect among the country’s elites. The authorities have now arrested or imprisoned three former federal government ministers and a supporting cast of regional officials

The reaction to this type of paternalism, sensible and well-meant as it usually was, came in the form of petulant populism. Like a child who refuses to eat his spinach, just because his mother claims it is good for him, supporters of Trump, Brexiteers, or Baudet want to give the finger to the politics of virtue. That is why Nigel Farage, the chief promoter of Brexit, likes to be photographed with a glass full of beer and a smoldering cigarette: if the virtuous elite want us to drink less and quit smoking, let’s have another and light up.

Chinese President Xi Jinping seems to be on a roll. He has sent a rocket to the dark side of the moon, built artificial islands on contested reefs in the South China Sea, and recently enticed Italy to break ranks with its European partners and sign on to China’s Belt and Road Initiative. Meanwhile, US President Donald Trump’s unilateralist posture has reduced America’s soft power and influence. China’s economic performance over the past four decades has been truly impressive. It is now the main trading partner for more than a hundred countries compared to about half that number for the United States. Its economic growth has slowed, but its official 6% annual rate is more than twice the American rate. Conventional wisdom projects that China’s economy will surpass that of the US in size in the coming decade. Perhaps. But it is also possible that Xi has feet of clay.

"......as prime minister, May called a snap election in the name of helping her deliver Brexit. She openly dismissed anyone opposing Brexit – which at the very least meant the 16.5m who had voted remain – as “playing games with politics”. In hock to the hardline Brexiteers within her own party, May pushed a for a version of Brexit that would make this small group of around 100 or so individuals happy, regardless of what millions out in the country thought."

The financial crisis occurred in 2008 because deficient regulation allowed huge risks to develop within the financial system itself. But the depth of the subsequent recession, and the long period of slow growth that followed, was the result not of continued financial system fragility, but of the excessive leverage in the real economy that had developed over the previous half-century. Between 1950 and 2007, advanced economies’ private-sector debt (households and companies) grew from 50% to 170% of GDP and adequate growth seemed attainable only if debt grew far more rapidly than nominal GDP. After the crisis, loan growth turned negative and remained depressed for many years, not because an impaired financial system lacked the capital to extend credit, but because overleveraged households and companies were determined to pay down debt even if interest rates were zero. The same pattern was observed in Japan in the 1990s.

The American people should have known that something was awry when President Donald Trump’s attorney general, William Barr, announced on Friday, March 22, that he had received special counsel Robert Mueller’s report and would provide a summary of its findings to certain congressional leaders over the weekend. We should have asked: Why Barr’s summary and not Mueller’s? Presumably, Mueller had attached one to his report. It turned out there was a propagandistic reason for this unusual arrangement: Barr issued the best possible interpretation of Mueller’s report – from the president’s standpoint – including perhaps even a twist on what Mueller had said and intended. This allowed the president and his backers to propagate and celebrate what Mueller didn’t say: that the report’s conclusions were a “total exoneration” of Trump. In fact, even Barr’s brief summary, quoting Mueller’s report, said, “While this report does not conclude that the President committed a crime, it also does not exonerate him.”
