Nascent Signs of Stagflation?

UK may be the first country to manifest symptoms of stagflation or “a condition of slow economic growth and relatively high unemployment - a time of stagnation - accompanied by a rise in prices, or inflation” (investopedia.com).

Britain’s economy unexpectedly shrank the most in more than a year in the fourth quarter as construction slumped and the coldest weather in a century in December hampered services and retailing.

Gross domestic product fell 0.5 percent in the three months through December after increasing 0.7 percent in the previous quarter, the Office for National Statistics said in London today. Economists forecast a 0.5 percent gain, based on the median of 33 predictions in a Bloomberg news survey. Growth would have been “flattish” in the quarter without the impact of the weather, the statistics office said.

The U.K. recovery is losing momentum even before Prime Minister David Cameron’s government steps up its fiscal squeeze to cut the budget deficit. While the Bank of England left its key interest rate on hold this month to support the recovery, inflation has soared to an eight-month high and policy maker Andrew Sentance said late yesterday the “time has come to act” as price pressures intensify.

So economic contraction, which adds to unemployment amidst high inflation rates are signs of stagflation- a tradeoff which traditional Keynesian models have not incorporated.

Other developed economies are likewise seeing signs of emergent inflation

From the Economist:

Recently, however, rich-country inflation has also started creeping up: in December Britain’s consumer-price index hit 3.7%, while euro-zone inflation also rose above the ECB's target. Much of the blame has been put on the increase in commodity prices. But the impact on consumers differs widely between countries. A larger share of income is spent on food in poorer countries such as China (33%) and India (46%), so the rise in global food prices is the main driver of inflation there. By contrast, pricier energy is a bigger factor in the rich world, although it forms a relatively small component of consumer spending.

Given the near unanimity of policy directions by global central bankers, it is not deflation that we should worry about but stag- or super-inflation.
