After release of Japan's headline report for the CPI for May, it appeared that the way had been made clear for the Bank of Japan to begin to raise rates and began to move interest rates into more sustainable, neutral, long-term territory. A rate hike could also go some way toward helping to support the yen that has been struggling. Headline inflation in Japan is at 2.9%; while it dipped to a 2.1% pace over six months, it's running at a 3.8% annual rate over three months.
However, new data on the core suggested Japanese inflation is running substantially weaker than headline inflation suggests. The generic all items excluding food and energy metric was flat in May, up by 1.6% over 12 months, up by 1.2% at an annual rate over six months, and up at only a 0.8% annual rate over three months. Core inflation shows that inflation pressures are not broadly shared. The statistic for all items except fresh food and energy rose by 0.1% in May, and has a stronger 2.1% gain over 12 months, quite close to the Bank of Japan target. However, over six months, this core metric is up but only a 1.3% annual rate; over three months, it's up at only a 0.4% annual rate. Neither of the measures of the core inflation rate shows that there's much inflation stirring in the Japanese economy. They are far from giving the BOJ an ‘all clear’ signal for any kind of rate hiking. Their sequential progression to lower inflation rates over the past year underscore ongoing price weakness.
These are data through May so two-thirds of the monthly data are now in hand. Quarter-to-date all item inflation is rising at a 2.9% annual rate; inflation for all items except food and energy is up at just a 0.9% annual rate; and for all items except fresh food and energy, the rate of increase in the quarter-to-date is only 0.5% at an annual rate.
The quarter-to-date data for all items except fresh food and energy comes in very close to the five-year average for that series which showed an average annual increase of 0.6% per year. For all items ex food and energy, the gain of 0.9% in the quarter-to-date is higher than the 0.6% it averaged over five years. However, headline inflation of 2.9% quarter-to-date is up considerably more strongly than the five-year average pace of 1.4%.
