瑞郎第一季度暴跌，瑞士央行仍未干预外汇市场

Core Viewpoint - The Swiss franc experienced a significant decline in the first quarter, yet the Swiss National Bank refrained from intervening in the foreign exchange market for the fifth consecutive quarter [1] Group 1: Swiss National Bank Actions - The Swiss National Bank purchased only 49 million Swiss francs in foreign exchange from January to March, maintaining a consistent low level of intervention compared to previous quarters [1] - The decision not to intervene suggests that officials see no reason to act, especially after a surprising rate cut in December 2022 that led investors to withdraw funds from the Swiss franc [1] Group 2: Currency Performance - In the first quarter, the Swiss franc depreciated by 1.7% against the euro while appreciating by 2.8% against the US dollar [1] - The appreciation against the US dollar may be linked to heightened trade tensions, particularly following President Trump's announcement of comprehensive tariffs on April 2, which caused the Swiss franc to reach a historical high against the dollar [1]
