Alan Bollard: Everyone needs to play their part - inflation and recession
in the New Zealand economy
Speech by Dr Alan Bollard, Governor of the Reserve Bank of New Zealand, to the Wellington
Chamber of Commerce, Wellington, 10 December 2008.

The world economy faces some significant challenges. Finance markets have been going
through turmoil, the pace of global expansion has slowed abruptly, and policymakers have
focused on preventing a more pronounced slowdown. For some commentators, concerns
over inflation appear to have taken a back seat, for now at least. As the global economy has
weakened, commodity prices have fallen, substantially in some cases. Many commentators
are of the view that lower commodity prices and weak economic activity will drive inflation
significantly lower.
It is worth remembering that for the moment, however, inflation rates in New Zealand (and
many of our trading partners) remain very high. In the September 2008 year CPI inflation
reached 5.1 percent, the highest rate since 1990. The higher rates of inflation are
broadbased. These reflect some common drivers:
•
A strong run-up in world commodity prices, which have had a direct inflationary
impact. Oil prices increased nearly tenfold in USD terms in the decade to July 2008,
with global food prices also rising strongly. Prices of the milk, cheese and eggs
category rose 18 percent over the last year.
• The long-running expansion in domestic demand contributed to a build-up of
pressures on capacity and high rates of domestically generated inflation. So far,
weaker demand conditions have been slow to feed through into lower domestic
inflation. In the building industry for example, rising prices for raw materials and
strong wage inflation have continued to underpin high rates of construction cost
inflation.
•
There have also been sizeable price increases in areas not directly exposed to a
high degree of competition over the past few years. Increases in local authority rates
have run well in advance of overall CPI inflation for a number of years. Cost
increases in some utilities have also been notable, particularly electricity.
• In the banking sector, the cost of international funding has risen significantly and
become less assured. However, since July the Reserve Bank has cut the Official
Cash Rate by 3.25 percent. Short term mortgage rates have been cut, but not by
this much. Banks should not expect to be able to maintain high profit margins in the
current environment.

As the global economy has weakened, commodity prices have fallen again, substantially in
some cases. Since July, global oil prices have declined by two-thirds and are back to
mid2005 levels. Other commodity prices have also eased, including prices for our agriculturally
based exports, with international dairy prices now around half of where they were a year ago.
Sharply lower commodity prices are expected to flow through into lower consumer prices.
However, the impact on short-term inflation will depend on a number of factors including the
exchange rate, other costs, taxes, and firms' margins. In the past, these factors have tended
to mitigate the impact on retail prices. Although global oil prices more than doubled between
mid-2005 and mid-2008, New Zealand retail petrol prices only increased by around 60
percent over the period. Retail petrol prices have been dropping recently, but we believe they
should be dropping further to restore refinery margins.
Similarly, retail dairy prices only increased around 25 percent from early 2007 to October this
year, while global dairy prices more than doubled to their peak in late 2007. In addition, there
was a lag of more than six months before higher global dairy prices flowed through to the
retail level. However, now that global prices have crashed, there is plenty of room for retail
price cuts.
The exchange rate has tended to play a buffering role and has helped moderate the impact
of large swings in global commodity prices in New Zealand dollar terms. Despite the
substantial appreciation of the New Zealand dollar between 2002 and 2007, tradable CPI
inflation has remained quite high. This may partly reflect trends in global import prices, but it
is also likely to reflect some importers widening their margins when the NZD was going up
and demand conditions were more favourable. While the lower NZD will eventually lead to
higher inflation, this will be tempered by lower global import prices and a narrowing in firms'
margins to reflect the current demand climate. The prevalence of discounting and reports of
high retail stocks suggest some temporary respite for retail prices from the lower dollar.
As a result of all this, the Bank's December Monetary Policy Statement projections are for
annual CPI inflation to trough around 11⁄2 percent in the September 2009 quarter, before
lifting slightly above 2 percent thereafter.

We need to see inflationary pressures reducing significantly across the board, if we are to
keep on easing monetary policy, thus helping the New Zealand economy to recover. That
depends on all sectors of the economy responding to the reduced demand and not adding
inflationary pressures to the system.
Some examples: we would hope that the electricity industry does not take advantage of its
market position and keep increasing rates, that local authorities realise they need to set rates
increases below inflation for a change, that the construction materials industry respond to
much weaker demand, that the food industry react to lower international commodity prices
with price cuts, that petrol companies keep cutting forecourt prices, that the transport industry
pass on fuel price cuts, and that the banks pass on interest rate cuts. Only then will all these
firms be playing their proper role in New Zealand's recovery.
