us to cooperate to lay the foundation for strong, sustainable and balanced growth”<br />

is an acknowledgement of the increased economic weight of emerging economies.<br />

At the global level, in the coming years strong economic growth may require<br />

a rebalancing of growth in deficit countries, such as the US, the UK and Spain,<br />

from domestic consumption to exports, while a reverse process would be needed<br />

in surplus countries such as China, Japan and Germany. US saving rates have risen<br />

recently and this single factor could impact growth substantially given the fact that<br />

private consumption accounts for 70% of GDP. It is likely that the savings rate<br />

will remain higher than in the years preceding the crisis, due to the necessity for<br />

private households to deleverage. Meanwhile the Chinese government remains committed<br />

to fiscal expansion and to the aim of rebalancing growth towards domestic<br />

consumption, and in the higher economic growth scenario, this would provide an<br />

important growth impetus.<br />

As with the lower economic growth scenario, the stronger growth that emerges<br />

in the higher economic growth scenario is a credible alternative to the Reference<br />

Case. Therefore, the assumption is made that average global growth over the period<br />

is 0.5% p.a. higher than in the Reference Case throughout the projection period.<br />

In turn, there is an assumed correction of oil prices in accordance with demand<br />

developments. 51 This gives rise to some feedback impacts upon both demand and<br />

supply, but the dominant effect remains through the alternative economic growth<br />

assumptions.<br />

The results for these two scenarios are shown in Tables 4.3–4.6, and summarized<br />

in Figures 4.2 and 4.3. In the lower growth scenario, demand by 2035 reaches<br />

100.6 mb/d, or about 9 mb/d lower than in the Reference Case. 52 Because of the<br />

slightly softer oil prices, non-OPEC oil supply is lower than in the Reference Case by<br />

about 2 mb/d by 2035. This means that the call on OPEC crude oil by 2035 is 7 mb/d<br />

lower than in the Reference Case. In this scenario, the need for OPEC crude oil rises<br />

slowly to around 32 mb/d, where it stays approximately flat.<br />

In the higher economic growth scenario, global oil demand rises more swiftly,<br />

to reach over 112 mb/d by 2030 and 118 mb/d by 2035. Part of the pressure upon<br />

the demand rise is ameliorated by the higher oil price. Of course, this scenario<br />

would need to be placed into the context that such a strong demand increase would<br />

likely cause concerns over rising imports, which, in turn, would likely lead to new<br />

policies being introduced to limit growth. Nevertheless, it demonstrates the innate<br />

uncertainty over future oil demand due to economic growth, from both the upside<br />

and downside. In this scenario, OPEC crude supply would need to rise to 45 mb/d<br />

by 2035.
