Commodity prices continued along a rising trend during the last quarter of 2009, with the improving perception regarding the global economic recovery (Figure 32). Accordingly, oil prices hovered above our assumption of 70 USD per barrel for the fourth quarter (Figure 33). Therefore, oil price assumptions stated in the previous Report have been revised in line with futures prices registered during the first half of January. In this context, the previous assumption of oil prices have been revised up from 75 USD per barrel to 80 USD for 2010, and from 80 USD to 85 USD for 2011 and thereafter (Table 1). This revision has added around 0.2 percentage points to the 2010 inflation forecasts. Moreover, in line with oil prices, imported input prices are also assumed to increase gradually throughout the forecast horizon in response to the gradual recovery in the world economy. BIS Review 31/2010  13  The October Inflation Report envisaged annual food inflation to be 5.8 percent for 2009 and 6 percent for the years to follow. However, as I have mentioned earlier in my speech, unprocessed food prices exceeded our forecasts. Therefore, we revised our assumptions for food inflation up from 6 percent to 7 percent for end-2010 (Table 1) and this added around 0.3 percentage points to the 2010 inflation forecast. Similarly, assumptions for 2011 food inflation have been raised to 6.5 percent from 6 percent. We maintain our 6 percent annual food inflation forecast for subsequent years.
In the short term, many of the uncertainties obstructing the economic outlook – and especially the manufacturing sector – are man-made – and even one-man made. Contingencies that not so long ago appeared as tail risks, such as the possibility of an escalation of trade tensions or a disorderly Brexit, have become looming threats. But uncertainty also pertains to long-term structural trends. Over the past decade, the world economy has steadily recovered from the global financial  Page 2 sur 11 crisis. But it has not returned to its pre-crisis normal. Interest rates remain at historical lows, due to a historically low level of the natural rate of interest R* ii. In the short run, this analysis – uncertainty as the first trigger of the present slowdown – should guide our ranking of policy answers. Monetary policy plays its role, but it should not – less than ever – be the only game in town. It should not even be the first game in town. The first response would be for government-driven uncertainties to be addressed directly by governments, by removing the self-induced threats to world growth. Failing that, a second answer is for fiscal policy to step in. Fiscal stimulus from countries with fiscal space would both stimulate aggregate demand, and, with targeted, quality investment, increase long-term growth. iii Wage increases in countries that have long relied on wage moderation could also help in bolstering aggregate demand and inflation. And pro-growth reforms would raise R*. Monetary policy provides a third response.
