最近美国的就业成本指数（Employment Cost Index）有所上升，从今年三月的1.8%升到九月的2.2%，吸引了市场的关注。综合考虑其他因素，AMP首席经济师Bevan认为：这些变化只会继续支持现行货币政策的进一步正常化。
A couple of points. Firstly, the ECI is a broader measure of worker compensation as it also captures the cost of benefits. Benefit costs are rising at an annual rate of 2.4% – faster than wage growth which, while higher also than six months ago, is running at an annual rate of 2.1%.
Secondly it appears the recent rise in the wages component of the ECI just brings it back into line with average hourly earnings, the annual rate of increase in which has been tracking a little over 2% in the past few months. In that respect there is little new news in the ECI to get excited about.
But as I’ve said on numerous occasions before; it’s ultimately unit labour costs (ULCs) that matter most to the inflation outlook. ULC are clearly trending higher’ although admittedly it requires a 24-month moving average to find a nice fit with core inflation.
The upshot is that wage growth is off its lows and ULCs are trending higher. Core inflation remains subdued and may indeed continue to be subdued for a while yet. Core inflation excludes direct commodity price effects by excluding food and energy prices but second round effects of lower oil prices in particular are likely to keep core inflation pressures subdued in the near term. The higher USD will also keep inflation subdued.
But monetary policy must retain a medium term focus. The ECI is just the latest in a number of indicators that suggest continued monetary policy normalisation is warranted in America. We continue to expect the FOMC will leave interest rates unchanged into next year with the first interest rate increase likely in mid-2015.
