The turbulence in the global financial markets in the past few weeks has been widely attributed to a “China shock” that has increased the risks of a major downturn in global activity. Last month, this blog concluded that our regular “nowcasts” for global activity had not yet corroborated this narrative.

This month, we have identified the first clear evidence that the global economy has slowed down since mid year, with emerging markets and advanced economies both now growing more slowly. A new factor is a clear slowdown in the US economy, though much of this appears to be due to the temporary effects of an inventory shake-out.

The Chinese economy has not shown any further signs of slowdown in September. The dominant contractionary force in the global economy is a commodity shock, which of course is somewhat connected to events in China (as it rebalances its economy away from commodity-consuming sectors), but it is not exactly the same thing.

The commodity shock is redistributing activity away from commodity producers and towards commodity consumers, both within and between countries. Eventually, the commodity shock should be net beneficial to the global economy, but so far global activity growth has dropped to only 2.6 per cent, which is 0.4 per cent below the rate in mid year, and 0.8 percentage points below trend. This means that global spare capacity is currently rising at a worrying rate.

Because the emerging markets are much more exposed to commodity producers than developed markets, they have been hard hit by the commodity shock. They are now growing at 3.5 per cent, or 1.5 percentage points below trend. It is unclear whether this growth rate is still dropping.

In the advanced economies, the growth rate in activity is about 1.7 per cent, which is roughly at trend. The slowdown identified in the US in September has been offset to some extent by signs of firmer activity in the eurozone.

An important and worrying feature of global growth in 2015 has been the large drop in global industrial production relative to services in the second quarter. This was driven mainly by weakness in industrial production in the US energy sector – not in China – and it has since been reversed. Read more

This blog has been updated to incorporate the Japan GDP data published on Monday.

Japan, it seems, is still stuck between a rock and a hard place. The rather shocking gross domestic product figures just published for the third quarter show that the economy has fallen into yet another technical recession since the sales tax was increased in April. On this evidence, it will be hard to achieve fiscal sustainability without abandoning the economic recovery. Abenomics, which was supposed to resolve this longstanding dilemma, is in trouble.

Although Japanese GDP data are notoriously volatile from quarter to quarter, and this batch was depressed by a temporary burst of inventory shedding, underlying consumer and corporate spending is very weak. Aggressive monetary easing and a huge devaluation have not been enough, as yet anyway, to overcome the effects of even a modest fiscal tightening.

In the next few days, Prime Minister Shinzo Abe is widely expected to react to the GDP figures by announcing that the second leg of a sales tax increase, scheduled for October 2015, has been postponed until 2017. Since this delay would be supported by two-thirds of the Japanese electorate, it may be the prelude to a snap general election in December.

In itself, the postponement of the sales tax increase will have a negligible effect on fiscal sustainability, and it will help restore the economic recovery next year. But the fact that it needs to be considered at all raises wider questions about the longer term success of Abenomics. Read more

The month just ended was the fourth worst month for government bond returns in the past two decades. This abrupt response to Ben Bernanke’s warning that the Fed might think about tapering QE at some point in the next few meetings has naturally raised fears that the great bull market in fixed income, which started in 1982, might now be threatened by a sharp reversal.

Some analysts regard this as the inevitable bursting of a bubble which has been created by the actions of the central banks (see this earlier blog). Others, like Jim O’Neill, regard the rise in bond yields as the start of a return to economic normality, and argue that would be a very good thing as long as it occurs in an environment of recovering economic confidence. Paul Krugman also points out that the pattern of behaviour in the major markets – bonds down, dollar up and equities up – is consistent with greater optimism about the US economy, rather than worries about the Fed or the onset of a debt crisis. Read more

Kuroda gives first press conference as governor of BoJThe package of quantitative easing announced today by the new regime at the Bank of Japan is one of the largest monetary injections ever announced by the central bank of a major developed economy. The only rival for that crown is the emergency easing in monetary policy which took place in most economies in late 2008. But today’s BoJ action has not been driven by any short-term emergency. It represents a deliberate change in philosophy, and a complete abandonment of everything that the Bank of Japan has said about monetary policy in the past two decades. Those who believe in quantitative easing certainly have their experiment, writ large in Tokyo.

In effect the new governor, Haruhiko Kuroda, has imported into Japan the whole of the Federal Reserve’s post-Lehman balance sheet strategy, and he will implement it in under two years, instead of the five years or more taken by the Fed. The doubling in the Japanese monetary base over a period of 21 months is in itself remarkable. Taken together with the extension of the duration of bonds purchased from less than 3 years to an average of 7 years, the injection becomes of historic proportions.

The new strategy brings, for the first time, a real prospect of breaking the deflationary psyche which has plagued Japan for so long. But it also brings risks that the strategy might work too well, with inflation expectations unhinging the bond market. Mr Kuroda is trying to pull off a difficult trick, which is “to drastically change the expectations of markets and economic entities”, and to do so in a very particular way. Read more

The Bank of Japan’s monetary policy meeting on Tuesday is the focus of much greater global attention than normal. The Japanese economy is headed into yet another downturn, and the central bank seems likely to admit that its 1 per cent inflation target will not be achieved in fiscal 2014. The meeting will probably end with another round of increased asset purchases, lifting the BoJ’s total purchase programme from Y80trn to about Y90trn-Y95trn.

That, however, is not the real reason why the BoJ is back on the global radar screen. Yet another modest rise in asset purchases, which analysts have termed “QE9″, is unlikely to impress anybody. The real reason for market attention is that there is now enormous political pressure on the BoJ to do something much more dramatic to help the economy break out of its deflationary trap. Read more

Until recently, Keynes’ notion of a liquidity trap was of great interest to macro-economists, but was viewed by investors as a rare aberration which, outside Japan, could be safely ignored. In the aftermath of the 2008 credit crunch, all that has changed. Many developed economies seem to be falling into a liquidity trap, and may stay there for several years. What does this imply about asset returns? (This blog is a slightly longer version of an article which first appeared in the FT’s Market Insight column on 24 January, 2012.) Read more

Global equities and other risk assets ended last week near to their high water marks for the year. Once again, markets have reacted favourably to the most important indicators for global activity, all of which have been published in the past week.

There have been some signs that higher oil prices have dampened consumer spending in the US, and the global industrial sector has given further evidence of reaching its peak growth rate. But so far any slowdown has been very minor, and not enough to persuade markets that this is anything more than a temporary correction.

In my regular weekly round-up this week, I will comment on the implications of recent data for the major economies. Read more

The sudden surge in the value of the yen to a new all-time high against the dollar is a new headache for the Japanese authorities, just at the moment when they did not need one. In the aftermath of the Kobe earthquake in 1995, the yen temporarily surged by almost 20 per cent against the dollar, and a repeat of that episode now would greatly add to deflationary pressures in the economy. Fortunately, however, the Bank of Japan should be in a position to stop this from happening, and other G7 economies will hopefully realise that this is one area where they can really help Japan. There may not be many occasions where co-ordinated foreign exchange intervention is the right thing to do, but this is certainly one of them. Read more

The Kobe earthquake of 1995 was an immense human tragedy, hitting a region of Japan where building standards were nowhere near adequate to cope with the shock. I am sure we all have very sad memories of a disaster in which more than 6,000 people died. Read more

China’s GDP growth made news this week because, on the official figures, China overtook Japan to become the second largest economy in the world in 2010. But actually, on a different way of calculating the data, this was very old news. Using purchasing power parity, China not only overtook Japan way back in 2001, but it is also quite close to overtaking the US as the biggest economy in the world – if, indeed, it has not done so already.

GDP statistics measure the amount of value added or income in the economy, measured in domestic currencies, over a given period of time. But it is more difficult to compare the GDP in one economy (China) with that in another economy (Japan), because we need to use an exchange rate which translates yuan into yen or vice versa. This is not as straightforward as it may seem. Read more

Today’s publication of the latest FOMC minutes will probably unveil significant downward revisions to the Committee’s inflation and gross domestic product forecasts for 2011, as well as a large upward revision to its unemployment forecast. More interestingly, the minutes will show whether the FOMC is broadly united on the strategy of quantitative easing which it has now adopted.  Read more
