Are the inflation risks in emerging markets exaggerated, asks Stefan Wagstyl. Yes, says Capital Economics in a report published on Monday that argues that the inflation fears spooking EMs will “prove short-lived”. Not true, says HSBC Asset Management, which says investors are “overly sanguine on EM inflation prospects”, with the consensus lagging reality.

The key to the argument is how far rising global commodity prices trigger second-round inflationary effects in individual countries. And how fast the authorities intervene. Capital Economics argues that, while inflation is above official target levels in 11 of the 14 largest EMs and will edge higher, it should peak in the fourth quarter.

It says: “Even if global commodity prices now simply stabilise at their current high levels, food and energy inflation should still start to fall by around Q4 of this year. But if last week’s drop in oil prices proves to be the start of a series of falls in global commodity prices, as we think likely, food and energy inflation could drop sharply next year.”

Either way, the key point is that the unwinding of the commodity price shock, coupled with a more general slowdown in the global economy, should lead to a fall in headline inflation in most EMs next year.

Capital Economics admits there are domestic inflationary pressures in some countries, including Indonesia, India, Turkey and Brazil. But China is less vulnerable. And overall the scene is set for an eventual recovery in investor sentiment towards EMs.

“The upshot is that the inflation fears that have spooked financial markets in emerging economies over the past week or so are ultimately likely to prove short-lived. Other headwinds remain – most notably fears for the global recovery. But with growth in the developed world likely to remain sluggish, the hunt for higher returns should eventually pave the way for a renewed influx of capital to emerging markets and further gains for EM equities and bonds.”

For HSBC Asset Management this is too optimistic. In a report entitled “Who let the tigers out?” Philip Poole, global strategy head, quotes approvingly from Wen Jiabao, Chinese prime minister. “Inflation is like a tiger: once set free it is very difficult to get back into its cages,” said Mr Wen in March – and Mr Poole seems to agree.

First, he says, the upswing in commodities is “more trend than cycle”, driven by EM demand for energy, materials and food. Next, the second-round effects of inflation – in which domestic companies and workers push up prices and wages – are serious. “This creates the risk that in emerging economies inflation shocks turn into self-perpetuating inflation processes as expectations adjust higher and become embedded.”

Finally, EM central banks’ ability to control inflation through interest rate rises is damaged by the US Federal Reserve sticking to very loose monetary policies. So instead of raising rates, central banks are turning to controls on banks. The longer central banks put off rate increases, “the bigger the risk they slip behind the curve in combating inflation”.

For Capital Economics, the implications for investors are straightforward – buy EM stocks and bonds, taking advantage of market dips. HSBC AM, with its longer-term concerns about inflation, suggests buying asset-intensive sectors including banks and minerals groups.
