这是高盛眼中“美国经济和市场的最大风险”

Core Viewpoint - Goldman Sachs indicates that the primary risks facing the U.S. market and economy are shifting from private sector financial excesses to escalating public sector debt issues and high asset valuations [1][2]. Fiscal Sustainability - The report highlights that the greatest long-term risk for the U.S. is fiscal sustainability, with concerns that rising national debt and interest payments could necessitate sustained large fiscal surpluses, which are politically challenging [2]. - Any resulting upward pressure on interest rates could tighten the broader financial environment and hinder economic growth, especially given the already high asset valuations [2]. Asset Valuation Concerns - Despite high interest rates and geopolitical uncertainties, U.S. stock market valuations remain at their highest levels since the late 1990s, with a current price-to-earnings (P/E) ratio of 22.4, significantly above the historical average of 15.9 since 1990 [2]. - The speculative trading index from Goldman Sachs indicates heightened market risk, with phenomena like "Meme stocks" reflecting increased market risk appetite [2]. Real Estate Market Analysis - Goldman Sachs expresses limited concern regarding high real estate prices, attributing them to a persistent supply-demand imbalance rather than loose lending standards or speculative buying [3][4]. - The shortage of single-family homes is expected to continue, limiting the risk of significant price declines [4]. Household Debt Insights - The report addresses two main concerns regarding household debt: low savings rates are fundamentally linked to household wealth levels, and rising consumer credit default rates reflect past risky lending practices rather than a general deterioration in household financial health [5]. - Current default rates are stabilizing, indicating manageable household debt levels [5]. Corporate Debt Overview - Although corporate interest expenses have risen significantly in recent years, the consequences appear limited at this time [6]. - Goldman Sachs estimates that refinancing maturing debt will only increase interest expenses by 3% over the next two years, a significant decrease from the previously estimated 7% for 2023, due to much of the debt being refinanced in a higher interest rate environment [7].
