The prime minister's strong advocacy of fiscal stimulus and harsh criticism of higher interest rates ‌have heightened investor concerns about worsening public finances in Japan, sending bond yields higher. Those bond market anxieties have also blunted official efforts to talk down speculative bets against the yen, government sources said. For example, her spending plans, aimed in part at easing rising household living costs, lifted bond yields to three-decade highs in July on concern over Japan's worsening finances. "I would say communication with markets would become more important," she said ⁠when asked what she could have done better. While the move would come as little surprise, a lack of funding clarity could further upset bond markets, analysts say.
