Imbalances in the global economy are lower now than before the collapse of Lehman Brothers a decade ago but other risks have emerged, says Keith Wade, as he examines the new fault lines that could trigger another crisis
Ten years on from the collapse of Lehman Brothers and the deepening of the global financial crisis, the world seems to be a safer place. Over the past decade there have been significant shifts in the world economy to the extent that the imbalances that could lead to a crisis are less. The risks have not entirely gone away, but they have shifted and are different to those of a decade ago.
The global financial crisis had its origins in a savings glut that built up as emerging markets, notably China, developed an excess of saving over investment. Much of the excess capital ended up in the banking systems of the developed markets, particularly the US and UK, where it was fed into the economy at ever-easier terms, with an explosion in sub-prime mortgage lending.
As the following chart shows, however, the surplus in the emerging world has disappeared while developed countries have moved from deficit to surplus. On the developed economy side, the swing into surplus was primarily driven by the eurozone, but the US also contributed to the turnaround with a sharp reduction in its deficit.
Global imbalances have reduced
Meanwhile, on the emerging market side, the move from surplus to deficit has been driven by China and the oil producers. The fall in the Middle East surplus largely reflects the decline in oil prices. For China, the overall current account surplus has fallen as a growing deficit in services now offsets a significant part of the surplus on goods. This services deficit is largely due to the huge increase in Chinese outbound tourism.
Overall, the reassuring news is that the scale of imbalances in the global economy is considerably less than 10 years ago. That said, we would draw out several areas of potential future stress.
* Emerging markets are more vulnerable: Emerging markets are not running a deficit at anything like the rate of the developed world prior to the financial crisis and many economies remain in surplus. Compared with the past, however, the region is more dependant on external capital.
Driven by China, emerging markets could move into deficit. Going forward the visible (goods) surplus is under pressure from the trade war as the US demands a $200bn (£152bn) reduction in its bilateral deficit with China. In addition, the invisible (services) deficit is likely to continue to grow as more Chinese take trips overseas.
* The US current account deficit persists: The US current account deficit has narrowed significantly over the past decade. The expansion of fiscal policy under the Trump administration and subsequent increase in the budget deficit is likely, however, to drive the current account deficit wider.
Jargon buster: Current account balance
The current account records a nation's transactions with the rest of the world - specifically its net trade in goods and services, its net earnings on cross-border investments and its net transfer payments. A country's current account balance may be positive (a surplus) or negative (a deficit). A positive current account balance indicates the nation is a net lender to the rest of the world, while a negative current account balance indicates it is a net borrower.
While the US economy is strong and interest rates have been rising ahead of the rest of the world, there has been little problem in financing this imbalance, as reflected in the strength of the US dollar. Yet, as monetary policy normalises elsewhere, US assets will look less attractive and financing will not be on such favourable terms. This may ultimately force a retrenchment of fiscal policy and a spell of weaker growth in the US.
* The inevitable appreciation of the euro? The major imbalance today is between the euro area and the rest of the world. The imbalance is sustained by the European Central Bank's (ECB) ultra-loose monetary policy, which is driving investors out of the euro and into other currencies in search of yield.
The weak euro has been an important tool in the battle against deflation. The pressure for appreciation is always there, however, given the region's large current account surplus and, while the ECB has so far been successful in preventing a sharp rise, eventually the currency will strengthen. Such a development would pose a significant challenge to the eurozone, which is still struggling to generate sustainable 2% inflation and faces considerable growth challenges in parts of its periphery.
New fault lines are emerging
The reduction in imbalances is reassuring for the world economy and future growth. In particular, the world economy is no longer dependant on the recycling of China's surplus into the US. The flipside is that the emerging markets have become more vulnerable to tighter global liquidity conditions. Moreover, there is a considerable challenge being faced by the eurozone which has become the "new China" in the world economy in terms of its current account surplus.
Consequently, in thinking about fault lines that could trigger the next crisis, we would focus on the eurozone, which currently combines a current account surplus with a weak currency only through an extraordinary loose monetary policy.
In a perfect world, eurozone recovery would be accompanied by higher interest rates and a stable currency. In practice, this could prove a major challenge as the ECB attempts to unwind its stance without a significant appreciation of the euro and subsequent risk of derailing activity in the region.
There is a danger that, like Japan before it, another economy with a current account surplus and inability to create inflation, the eurozone will find itself stuck with a very loose monetary policy for an indefinite period.
