Interest rates and Stock Prices: An Old Market Debate Replayed!
Global Convergence of Government Bond Rates
The trend of rising government bond rates is not confined to the US; it's a global phenomenon observed across major currencies like the British pound, Euro, and Japanese yen. This convergence, particularly stark after the historically low rates of 2021, has significantly impacted investment strategies like the carry trade, which relied on interest rate differentials. While developed markets show this trend, some emerging markets exhibit different patterns, highlighting a divergence. This global shift suggests a new economic order where interest rate differentials are narrowing, making traditional arbitrage strategies less viable.
The Nuanced Impact of Rates on Equities
Unlike bonds, the effect of rising interest rates on equities is complex because corporate cash flows (revenues, earnings, reinvestment) are not fixed and can be influenced by rate changes. Companies with strong pricing power and low input costs may pass on inflation, potentially increasing equity value. Conversely, those with high input costs and long-term reinvestment projects may see their value decrease. The discount rate for equities also rises, but the net effect on equity value depends critically on why rates rose (inflation vs. real growth) and how cash flows are impacted. US equities have shown resilience in 2026, with the S&P 500 and NASDAQ posting gains, suggesting that rising earnings are currently offsetting the negative impact of higher rates.
Earnings Growth Buffers Rate Hikes
The resilience of the S&P 500 in 2026, despite rising interest rates, can be attributed to a significant increase in earnings expectations. Analyst expectations for 2026 earnings rose by approximately 11%, and for 2027 by about 8-10%. This upward revision in earnings has buffered the market against the negative effects of higher rates, suggesting that corporate profitability is a key mitigating factor.
Global Equity Performance and Regional Variations
Globally, equities saw an 11.28% return in 2026, adding $17 trillion in market cap, with the US market up around 13%. However, performance varied significantly by region. Eastern Europe and Russia showed strong aggregate returns, though this was from a small base. Conversely, China and India, major emerging markets, experienced declines, with median Indian stocks down 10% and median Chinese stocks down 9% in dollar terms. These regional differences are influenced by macro factors like economic growth and oil prices.
