Former Bank of Japan executive Kenzo Yamamoto said the next BOJ rate increase is
likely to occur before December, sooner than the December move most economists
expect. He pointed to a BOJ measure of potential inflation excluding fresh food
and state aid that has averaged about 3% over the past four years, above the 2%
target. By contrast, Japan’s core CPI excluding only fresh food was 1.4% in May,
a level Yamamoto attributed largely to Prime Minister Sanae Takaichi’s
cost-of-living relief measures; the BOJ says price trends remain slightly below
2%. Yamamoto added he would be concerned if the BOJ treated the
potential-inflation measure as unreflective of price trends and said policy
should shift toward reining in inflation.
