Reuters-The world’s economic powerhouses are poorly equipped to deal with the next emergency. That’s the main lesson from the latest confab of leading central bankers and finance ministers in Shanghai. Though fears about an imminent crisis look premature, the outbreak of bickering about fiscal and monetary policy doesn’t bode well for the next downturn.

It’s been years since a meeting of the Group of Twenty developed and emerging economies led to substantial action. Expectations for the latest G20 gathering were therefore low, and the participants duly delivered. Indeed, the two-day meeting in Shanghai’s Pudong district served mainly to highlight deep global divides.

Take monetary policy. The selloff in global markets this year is at least partly based on the concern that ultra-low interest rates have lost their ability to stimulate growth and that central banks – in the latest iteration of the military metaphor – are out of ammunition.

Big economiesThough central bankers predictably reject this view, there’s little sign that they agree on what to do next. The latest weapon to emerge from the arsenal – the shift to negative interest rates – has not only rattled investors, but also exposed tensions in what is normally a tight clique of policymakers.

While in Shanghai, Bank of England Governor Mark Carney warned about negative interest-rate policy that attempts to insulate the domestic banking sector from its effects. This was, he said, designed to drive down the exchange rate, transferring weak demand to other countries, thereby “pulling the global economy closer to a liquidity trap”. Though Carney did not say so, he was clearly criticising his Bank of Japan counterpart Haruhiko Kuroda.

Living dead

The need for more government spending is another source of strain. Before the meeting the International Monetary Fund reiterated its view that countries with relatively low debts could “do more” to boost demand, for example by borrowing to fund infrastructure investment.

But the finance minister of one of those countries, Germany’s Wolfgang Schaeuble, dismissed the notion that the world could solve its problems with more leverage. “The debt-financed growth model has reached its limits,” he told a conference organised by the Institute for International Finance. “If we continue on this path we will no longer need to watch television. The living dead will overwhelm us.”

In the past, the United States might have been able to bully participants into a more meaningful agreement. But with a domestic presidential election campaign dominated by isolationism and downright xenophobia, America is hardly in a position to show global leadership. Host nation China, meanwhile, was more intent on reassuring the world about its ability to manage the economic slowdown at home.

PR blitz

Leaders from the People’s Republic applied the Shanghai spotlight for a public-relations blitz targeted at countering fears in regards to a further more devaluation of the yuan. Premier Li Keqiang promised the currency would continue to be “basically stable” – a note Zhou Xiaochuan, governor of the People’s Lender of China, reiterated at a unusual press conference.

The onslaught acquired some impression: China was notably absent from the problems posted in the G20’s last communiqué. On the other hand, the outbreak of openness didn’t offer a lot more clarity about how precisely China is taking care of its currency. Investors had been audibly exasperated when PBOC Deputy Governor Yi Gang informed the IIF meeting that the central lender currently monitors three several steps of China’s trade-weighted exchange price.

The consequences of the disunity should not be overstated. As the G20 pointed out, turmoil in financial markets is at odds with a global economy that is still expected to grow by almost 3.5 percent this year.

Nevertheless, the divisions that were on display in Shanghai suggest the world’s biggest countries are poorly prepared to deal with the next shock when it inevitably occurs. Perhaps it takes a full-scale crisis for the G20’s members to set aside their differences and take some substantial decisions. The rest of the world may find out soon enough.
