惊人相似，40年前历史正重现，1987美国股灾“黑色星期一”将卷土重来？

Core Viewpoint - The article draws parallels between the current economic situation in the U.S. and historical events from 40 years ago, particularly focusing on the potential for a repeat of the "Black Monday" stock market crash due to factors such as a weakening dollar and changes in Federal Reserve leadership [1][2]. Group 1: Economic Context - The U.S. dollar has depreciated nearly 10% this year, reaching a three-year low against major currencies, coinciding with Trump's return to the White House [1]. - The S&P 500 and Nasdaq have reached multiple all-time highs, driven by expectations of monetary easing and improved trade relations [2]. Group 2: Historical Comparison - The article references the "Plaza Accord" of 1985, which led to a significant decline in the dollar and a simultaneous rise in U.S. stock markets, with the dollar falling 36.5% against the yen and 30.8% to 36.6% against other major currencies over 17 months [2][4]. - Despite the dollar's decline, U.S. import prices did not significantly rise, aided by falling global oil prices, which helped maintain low inflation [4]. Group 3: Federal Reserve Leadership Impact - The market's confidence during the "Plaza Accord" era was largely attributed to then-Fed Chairman Paul Volcker's reputation for controlling inflation, which reassured investors [5]. - The transition to Alan Greenspan as Fed Chairman in 1987 marked a shift, as he failed to respond to critical market signals, leading to a loss of confidence and ultimately contributing to the "Black Monday" crash [6]. Group 4: Hypothetical Scenarios - The article posits that if Volcker had remained in charge, he likely would have acted to stabilize the dollar and control inflation, potentially preventing the market crash [7].
