下调到0？央妈严防人民币升值过快，广场协议的陷阱，中国不能踩

Core Viewpoint - The Chinese central bank has implemented urgent policies to stabilize the yuan amid significant fluctuations in the foreign exchange market, aiming to counteract the rapid appreciation of the currency and prevent a potential financial crisis [2][11][30]. Group 1: Central Bank Policy Actions - On February 27, the People's Bank of China announced targeted foreign exchange market control policies, effective March 2, which included reducing the foreign exchange risk reserve ratio for forward sales from 20% to 0% [6][11]. - The previous 20% reserve requirement increased costs for banks and ultimately for enterprises, making it more difficult for them to engage in forward foreign exchange transactions [8][11]. - The central bank's decision to eliminate this reserve requirement aims to lower the costs for enterprises hedging against exchange rate risks and to stabilize the foreign exchange market [11][23]. Group 2: Market Dynamics and Impacts - As of early 2026, Chinese enterprises held foreign exchange deposits totaling $932.2 billion, nearly equivalent to Germany's annual GDP, reflecting a significant accumulation of foreign exchange positions [16]. - The rapid appreciation of the yuan has led to substantial exchange rate losses for companies holding foreign exchange, negating the benefits of interest rate differentials they previously enjoyed [18][21]. - In response to these losses, many enterprises began to sell dollars and buy yuan to lock in losses, which further exacerbated the yuan's appreciation and created a feedback loop of market pressure [21][23]. Group 3: Historical Context and Global Considerations - The central bank's policy adjustment is informed by historical precedents, particularly the 1985 Plaza Accord, which serves as a cautionary tale against allowing external forces to manipulate domestic economic conditions through currency interventions [26][28][30]. - The central bank has emphasized that it will not permit excessive unilateral appreciation of the yuan or abnormal capital flows, aiming to maintain stability in the foreign exchange market [30]. - The recent policy changes are part of a broader strategy to respond to global monetary dynamics and to safeguard the yuan's pricing power in the international market [24][30].
