US financial markets are exhibiting characteristics of a brewing crisis, with soaring valuations, mounting leverage, and trade tensions creating significant risks. The Shiller cyclically adjusted price-to-earnings (CAPE) ratio is near historic highs, and the Buffett Indicator suggests the market is significantly overvalued. Margin debt has surged to a record $1.4 trillion, fueled by borrowed money. Non-bank institutions now dominate leveraged lending and mortgage originations.
