Bernard Hickey details in this third of our Top 10 charts for 2010 how the Reserve Bank's view of short term interest rates has changed markedly over the year.
Back in in its December 2009 monetary policy statement, the Reserve Bank forecast that the 90 day bank bill rate would rise by 370 basis points from the 2.8% then to a peak of 6.5% by the March quarter of 2013.
Seeing the need to tighten loose monetary policy to control inflation, the Reserve Bank hiked the Official Cash Rate by a total of 50 basis points to 3% in the middle of 2010.
But by the end of the year the Reserve Bank was forecasting 90 day bill rates would only rise 120 basis points to a peak of 4.4% by the March quarter of 2013.
What caused the Reserve Bank to radically lower its forecast for interest rates?
The recovery that was supposed to be in full swing by the end of 2010 had dried up and gone away.
GDP grew just 0.1% in the June quarter and actually fell 0.2% in the September, meaning the New Zealand economy barely avoided a double dip recession.
Consumers were reluctant to take on more debt and the September earthquake in Christchurch gave the economy a jolt in the quarter. The housing market slowed again.
Growth in America and Europe was slower than expected, although China and Australia continued growing faster than the rest of the global economy.
The Reserve Bank also saw inflationary pressures seeping away, despite the expected one-off boost from the GST increase to 15% from 12.5% on October 1.
Here is the bank's December 2010 forecast track for the 90 day bill rate below. The bank doesn't publish its Official Cash Rate forecast track, but it is unlikely to be too much different, given the 90 day bill rate is usually 30 to 40 basis points below the 90 day rate.

Here was the Reserve Bank's forecast track from its March 2009 Monetary Policy Statement, which included the December track (in red) below.
It shows how much the Reserve Bank has lowered its forecast track for rates through the year as the economy has slowed down.
