UK GDP growth is projected in our main scenario to slow from 3% in 2007 to
only around 1.75% in 2008 and around 1.25% in 2009.
Consumer spending growth is expected to slow more markedly to only around
0.5% in 2009 due to the severe squeeze on consumer spending from high debt
levels, tighter credit conditions, falling housing wealth and sharply
increasing household energy, petrol and food bills.
Separate analysis in this report shows that the poorest households will be
hit most severely by higher energy and food price inflation.
Business investment growth is also expected to moderate significantly in
the face of uncertainties relating to the global credit crunch, while public
spending growth is planned to be much more subdued than in recent years.
Slower global growth is likely to dampen exports, although this will be
offset by the weaker pound. Import growth is expected to slow, so enabling net
exports to make a modest positive contribution to overall GDP growth in 2008-9,
but this will be far too small to offset the consumer-led slowdown in domestic
demand growth.
Risks around growth in our main scenario are significant and have become
increasingly weighted to the downside in the recent months. The chance of a
recession has now risen to our 30% in our judgement, although this is still not
the most likely scenario.
In our main scenario, inflation is likely to rise further in the short term
but then fall back towards target during 2009, but there are still considerable
uncertainties around this relating to the path of global commodity prices.
Interest rates are assumed to remain on hold for the rest of 2008, but then
be cut during the first half of 2009 in our main scenario in response to slower
growth and falling headline inflation next year. But interest rate increases
cannot be ruled out if inflation accelerates further later this year,
particularly if inflationary expectations rise as well.
This issue includes an update of our earlier research looking at the
outlook for global carbon emissions to 2050. We now expect these to more than
double by the middle of the century in a ‘business as usual’ scenario, with
potentially severe adverse implications for climate change and the welfare of
future generations.
To avoid this outcome a wide range of measures are required to boost energy
efficiency, switch to low carbon fuels, introduce carbon capture and storage at
power stations and large industrial plants, and reverse deforestation. This
should be both technologically feasible and economically affordable if an
appropriate international policy framework is put in place to put a global
price on carbon, but it remains to be seen if the political will exists to meet
this challenge.
