35.	Normally, falling oil prices would boost global growth. This time, though, matters are less clear cut. The big economic question is whether lower prices reflect weak demand or have been caused by a surge in the supply of crude. If weak demand is the culprit, that is worrying: it suggests the oil price is a symptom of weakening growth. If the source of weakness is financial (debt overhangs and so on), then cheaper oil may not boost growth all that much: consumers may simply use the gains to pay down their debts. Indeed, in some countries, cheaper oil may even make matters worse by increasing the risk of deflation.
