贝森特表态“不干预”，市场抛售日元更“无所顾忌”了？

Core Viewpoint - The article discusses the recent statements by U.S. Treasury Secretary Janet Yellen, which have diminished the market's expectations of U.S. intervention in the foreign exchange market, particularly affecting the USD/JPY currency pair [1][8]. Group 1: Market Reactions - Following Yellen's statement on January 28, the USD/JPY pair rebounded sharply from around 152.7 to approximately 153.8, indicating a significant market reaction to the reduced intervention expectations [1]. - The "policy risk premium" associated with USD/JPY has been compressed, making shorting the yen a more attractive trade [2]. Group 2: Japanese Intervention Evidence - There is insufficient evidence to suggest that Japan has intervened in the currency market, as data from the Bank of Japan shows no significant buying of yen during recent declines in the USD/JPY pair [3][4]. - The focus has shifted from potential intervention to the sustainability of Japan's economic fundamentals [4]. Group 3: Key Economic Factors - Three main factors are influencing the pricing of USD/JPY: 1. Fiscal Policy: The upcoming Japanese elections and the ruling party's tax cut promises raise questions about funding sources, which could impact the yen's value if not clearly articulated [5]. 2. Inflation Expectations: Rising domestic inflation expectations have been correlated with a weaker yen, even in the absence of widening interest rate differentials [6]. 3. Monetary Policy: The yen's depreciation may compel the Bank of Japan to reconsider its monetary policy stance, particularly if the USD/JPY approaches the 150 level [7]. Group 4: Summary of Key Judgments - Yellen's "no intervention" statement has weakened the short-term defensive mechanisms for the yen [8]. - In the absence of clear intervention evidence, the market is more willing to test the upside potential of USD/JPY [8]. - Mid-term pricing will increasingly depend on Japan's fiscal, inflation, and monetary policy responses [8].
