The Reserve Bank of New Zealand (RBNZ) published its Sectoral Factor Model Inflation gauge for the first quarter of 2025, following the release of the official Consumer Price Index (CPI) by the NZ Stats early Thursday.
The inflation measure fell further to 2.9% year-over-year (YoY) in Q1 2025 vs. 3.1% in Q4 2024.
The inflation measures are closely watched by the RBNZ, which has a monetary policy goal of achieving 1% to 3% inflation.
FX implications
The Kiwi Dollar is unperturbed by the RBNZ’s inflation data. At the time of writing, NZD/USD is down 0.19% on the day at 0.5921.
About the RBNZ Sectoral Factor Model Inflation
The Reserve Bank of New Zealand has a set of models that produce core inflation estimates. The sectoral factor model estimates a measure of core inflation based on co-movements - the extent to which individual price series move together. It takes a sectoral approach, estimating core inflation based on two sets of prices: prices of tradable items, which are those either imported or exposed to international competition, and prices of non-tradable items, which are those produced domestically and not facing competition from imports.
(The story's title was corrected on April 17 at 3:30 GMT to say that "RBNZ Sectoral Factor Inflation Model drops to 2.9% YoY in Q1 2025," not dropped.)
Inflation FAQs
Inflation measures the rise in the price of a representative basket of goods and services. Headline inflation is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core inflation excludes more volatile elements such as food and fuel which can fluctuate because of geopolitical and seasonal factors. Core inflation is the figure economists focus on and is the level targeted by central banks, which are mandated to keep inflation at a manageable level, usually around 2%.
The Consumer Price Index (CPI) measures the change in prices of a basket of goods and services over a period of time. It is usually expressed as a percentage change on a month-on-month (MoM) and year-on-year (YoY) basis. Core CPI is the figure targeted by central banks as it excludes volatile food and fuel inputs. When Core CPI rises above 2% it usually results in higher interest rates and vice versa when it falls below 2%. Since higher interest rates are positive for a currency, higher inflation usually results in a stronger currency. The opposite is true when inflation falls.
Although it may seem counter-intuitive, high inflation in a country pushes up the value of its currency and vice versa for lower inflation. This is because the central bank will normally raise interest rates to combat the higher inflation, which attract more global capital inflows from investors looking for a lucrative place to park their money.
Formerly, Gold was the asset investors turned to in times of high inflation because it preserved its value, and whilst investors will often still buy Gold for its safe-haven properties in times of extreme market turmoil, this is not the case most of the time. This is because when inflation is high, central banks will put up interest rates to combat it. Higher interest rates are negative for Gold because they increase the opportunity-cost of holding Gold vis-a-vis an interest-bearing asset or placing the money in a cash deposit account. On the flipside, lower inflation tends to be positive for Gold as it brings interest rates down, making the bright metal a more viable investment alternative.
