Why Investors Care
As a measure of labour cost, the LCI helps the Reserve Bank of New Zealand measure inflation. The RBNZ, with an inflation target range of 1 percent to 3 percent uses this index in addition to other price indices to measure possible pressures in consumer prices.
RBNZ officials are always on the lookout for the prospects of inflationary pressures. Wage pressures tend to percolate when economic activity is booming and the demand for labor is rising rapidly. During economic downturns, wage pressures tend to be subdued because labor demand is down. By tracking labor costs, investors can gain a sense of whether businesses will feel the need to raise prices. If wage inflation threatens, it's a good bet that interest rates will rise, bond and stock prices will fall.
