Wall Street is gripped by a "high-rate panic" as the 30-year Treasury yield spikes to 5.3%, a near two-decade peak, while the 10-year yield approaches the critical 5% threshold. However, Goldman Sachs presents a starkly contrasting and pragmatic analysis: rising interest rates do not automatically trigger an equity market collapse, as corporate earnings remain the true engine driving stock performance. According to the latest research note, the core thesis is that while high rates act as a headwind for stocks, they are not a force capable of ending the bull market. As long as earnings growth remains robust and corporate balance sheets stay healthy, the foundation of the equity bull run can persist.

The report indicates that although the S&P 500's forward price-to-earnings ratio has contracted to 19 times from 22 times at the start of the year, the relative valuation of stocks versus bonds remains stable, with the equity risk premium holding at 3%. Investors are advised not to be shaken out by the initial discomfort of rate hikes, which historically average a 2% drawdown, given that the average 12-month return for the S&P 500 following a hike is a substantial +9%. Economists at the firm anticipate another 25 basis point rate increase at next week's Federal Reserve meeting.

Valuation Compression Has Occurred, But Relative Stock-Bond Appeal is Stable

The S&P 500's forward P/E has dropped to 19 times from 22 times since January. This de-rating stems from multiple factors, including AI-related uncertainties, skepticism regarding the durability of recent strong earnings, and the direct pressure from rising rates. Yet, the analysis reveals a key fact: the attractiveness of stocks relative to bonds has not materially deteriorated. The yield gap between the S&P 500's earnings yield (5.2%) and the real 10-year Treasury yield (2.6%) currently stands at 270 basis points, a spread that has remained remarkably consistent over the last two years. Furthermore, the equity risk premium implied by the dividend discount model is approximately 3%, also showing stability in recent years. This indicates that while rising rates compress absolute valuations, they do not systematically undermine the allocative value of equities compared to bonds, a key pillar supporting the bullish outlook.

Historical Precedent: Early Pressure from Hikes, But a +9% Average Return Over 12 Months

This week, the 10-year Treasury yield surged to near 5%, reaching its highest level since October 2023, with the 30-year yield climbing to 5.3%, close to its peak in two decades. Following a hotter-than-expected CPI print, economists predict a 25 basis point rate hike at next week's FOMC meeting. Strategists attribute the rise in long-end yields to higher oil prices, repricing of the Fed's rate path, robust economic growth, and the AI investment boom. A crucial buffer, according to the bank, is that the rates market has already priced in more than three 25 basis point hikes by mid-2027, raising the bar for further hawkish surprises and reducing the risk of a shock to the market.

Historical analysis of seven prior tightening cycles reveals a pattern: within three months of the first hike, the S&P 500 averages a -2% return with only a 29% probability of positive gains. However, over a 12-month horizon, the index averages a +9% return, achieving positive gains every time except for 2022. The 1997 case is particularly instructive: the Fed's single 25 basis point hike caused a 10% drop in the S&P 500, but the market bottomed out and hit new highs within three months once the market stopped pricing in further tightening. The medium-term impact of rate hikes on stocks ultimately hinges on how monetary tightening affects earnings growth, the market's primary driver. The firm projects S&P 500 earnings per share to reach $340 in 2026, up 24% year-over-year, and further to $385 in 2027, a 13% increase.

Stocks Show Greater Sensitivity to Long-End Rates, With Rate Volatility an Additional Risk

From a pricing logic perspective, stocks are essentially a discount of long-term future cash flows. The DDM model shows that approximately 75% to 80% of the S&P 500's present value comes from cash flows beyond 10 years out. Consequently, equity valuations are more sensitive to long-end rate movements, correlating strongest with the 30-year Treasury yield. Furthermore, it is emphasized that not just the level of rates, but also rate volatility itself, is a significant source of risk for the stock market. Historical data indicates markets usually struggle to digest rate moves exceeding two standard deviations. Currently, a two-standard-deviation move for the 10-year yield equates to a 40-50 basis point increase within a month, and the recent rapid pace of rising yields is a key contributor to equity market pressure.

Corporate Balance Sheets Remain Healthy, Limiting Fundamental Risk for Large Caps

Analysis suggests that current S&P 500 constituents exhibit strong fundamental resilience to rising rates. Most companies carry debt that is fixed-rate and long-duration, meaning the actual increase in borrowing costs is fairly limited. The overall interest coverage ratio for the index is at the 99th percentile of the last 20 years, with the median stock at the 68th percentile, both historically high. Interest expenses remain small relative to robust corporate profits. However, it is noted that small and mid-cap companies appear more vulnerable, typically holding weaker balance sheets and a higher proportion of floating-rate debt, making them more sensitive to rate increases.

Corporate Strategy: Boosting Growth is Key to Sustaining Valuations as M&A and AI Investment Accelerate

The firm's model provides a clear quantitative conclusion: a 1 percentage point rise in the cost of equity requires companies to lift their long-term growth expectations by 2 percentage points to fully offset the valuation impact. This pressure is driving several corporate responses:

1. Increased Capital Expenditure and R&D: In the current earnings season, roughly half of S&P 500 companies discussed using AI technologies to enhance productivity on their calls, with some planning to create new revenue streams. The urgent need to boost growth in a high-rate environment is a key supporting logic for the ongoing AI investment boom.

2. Accelerated M&A Activity: Announced M&A deals in the US have reached $1.4 trillion year-to-date, and global M&A volume is up 36% year-over-year. M&A serves as a vital pathway for companies to quickly improve their growth trajectories.

3. Business Divestitures: Spinoff activity has been relatively subdued in recent years, but rate pressure may encourage more companies to divest low-growth or non-core assets in a bid to streamline operations and refocus on growth.
