Key graphs

The key graphs summarise macroeconomic and financial market trends in New Zealand.

Since March 1999, the Reserve Bank has used the Official Cash Rate (OCR) as its tool for controlling inflation. By setting the OCR, the Reserve Bank is able to influence short-term interest rates such as the 90-day bank bill rate, as well as long-term interest rates and the foreign exchange rate. Data on the OCR and 90-day bank bill rate is available from 1990.

Data on the TWI and NZD/USD exchange rate is available from 1970.
