0613 GMT - The impact of rising oil prices on Japan's inflation is likely to be limited, and the rise in market-based inflation expectations will likely prove transitory rather than persistent, says SMBC Nikko Securities economist Junichi Makino. The government has said the country will likely have enough energy supply into next year via reserves and alternative sourcing. Although inflation expectations reached 2.1% as of Tuesday--slightly above the central bank's 2% target--they could drop from that level if oil prices fall and the yen's weakness unwinds, Makino says.
