日本央行为何维持利率不变？

Core Viewpoint - The Bank of Japan (BOJ) decided to maintain its policy interest rate at 0.75%, reflecting a careful balancing act amid concerns over fiscal deterioration and market pressures following the government's announcement of tax cuts and increased spending ahead of the upcoming elections [1][4]. Monetary Policy - The BOJ's decision to keep the interest rate unchanged is seen as a demonstration of the central bank's independence, which is crucial for price stability [5]. - The BOJ's economic outlook report revised core CPI forecasts, increasing the 2025 core CPI from 2.8% to 3% and adjusting GDP growth forecasts for 2025 and 2026 upwards, while slightly lowering the 2027 growth forecast [2]. Economic Context - The Japanese government announced plans for tax cuts and increased fiscal spending, leading to concerns about further fiscal deterioration and a subsequent drop in bond prices [1][3]. - The Japanese yen has been depreciating against the dollar and euro, with the exchange rate reaching historical lows, although the overall dollar depreciation against other currencies may mitigate further yen declines [3]. Market Reactions - The market had anticipated the BOJ's decision to maintain the interest rate, resulting in a muted reaction; however, this does not alleviate the downward pressure on Japanese government bond prices and the yen [4]. - The BOJ's previous interest rate hike in December was insufficient to halt the yen's depreciation trend, as the increase was modest and did not meet market expectations for a neutral rate adjustment [4]. Political Environment - The dissolution of the Japanese House of Representatives marks a significant political event, with elections scheduled for February 8, raising uncertainties about potential government interventions in the market during this transitional period [3][5].
