ASHEVILLE, North Carolina, Sept 1 (Reuters) - U.S. Treasury Secretary Scott Bessent urged Bank of Japan Governor Kazuo Ueda to conduct sound monetary policy to anchor inflation expectations and avoid excessive yen volatility, the Treasury Department said, cementing the case for a Japanese rate hike this month.
In a meeting with Ueda, Bessent also expressed "strong support" for Japan's steps to address the yen's undervaluation and noted how the weak yen was causing domestic
inflationary pressures, the Treasury said in a statement on Tuesday.
The remarks, which underline Bessent's recent calls for the BOJ to raise interest rates, bolster the case for the central bank to hike borrowing costs at its next meeting on September 17-18.
The two officials met on Sunday at the G20 finance ministers' and central bank governors' meeting in Asheville, North Carolina, the Treasury Department said in a statement.
"The Secretary emphasized the importance of sound formulation and communication of monetary policy to anchor inflation expectations and avoid excess exchange rate volatility," the statement said.
"Secretary Bessent also expressed strong support for Japan's decisive market and monetary steps to address the substantial undervaluation of the yen and noted the role of yen weakness in contributing to domestic inflationary pressures in Japan."
Ueda and Japanese Finance Minister Satsuki Katayama were attending a two-day meeting of the G20 finance leaders, ending on Tuesday.
A weak yen has pushed up import prices and broader inflation, causing headaches for Japanese policymakers by increasing households' cost of living.
The U.S. joined Japan in a rare joint yen-buying intervention on July 31, signaling their determination to prevent a selloff in the yen and Japanese government bonds from spilling over into global markets.
But the move has failed to put a sustained floor under the sagging currency, heightening market attention to whether the two countries can enter the market again.
Bessent, however, told Reuters that recent yen moves were not disorderly and instead called for BOJ rate hikes, saying he expects Ueda to "do the right thing" to combat yen declines.
While the BOJ was already widely expected to lift rates in September as inflation pressures grew, Bessent's comments effectively lock the bank into doing so and put pressure on it to step up hikes going forward.
A recent slew of hawkish BOJ communication has led markets to near fully price in the chance of a September rate hike, which would follow an increase in its policy rate to a 31-year high of 1% in June.
