Interest rate changes affect businesses through three primary transmission channels: (1) the discount rate used in valuations rises or falls, directly compressing or expanding present values of future cash flows; (2) debt financing costs change, altering leverage capacity and deal structures; and (3) capital allocation shifts as the opportunity cost of investment changes relative to risk-free returns. A 100bps increase in the risk-free rate typically raises WACC by 60-100bps depending on capital structure, reducing DCF valuations by 8-15% for growth companies. [src1]

├── YES → Prioritize debt capacity and coverage analysis
└── NO → Focus on discount rate and opportunity cost effectsAnalysts who keep using the same 10% WACC regardless of whether risk-free rates are at 1% or 5% produce meaningless valuations. [src1]
Rebuild WACC from current risk-free rate + equity risk premium + size premium + company-specific risk + after-tax cost of debt. [src1]
Banks earn wider net interest margins, insurers earn more on float, and cash-rich companies earn higher treasury yields from rising rates. [src2]
Map both assets and liabilities to rate sensitivity — a company with floating-rate receivables and fixed-rate debt may benefit from rate increases. [src2]
Rate changes affect customer demand, housing affordability, consumer credit, and business investment — ignoring revenue-side impacts produces incomplete analysis. [src3]
Build scenario models that adjust revenue growth assumptions alongside discount rate changes — a 200bps rate increase may reduce both the multiple and the earnings being multiplied. [src3]
Misconception: Higher rates always reduce stock prices.
Reality: Rate increases driven by strong economic growth often coincide with rising earnings that offset multiple compression. [src2]
Misconception: The impact of rate changes is immediate.
Reality: Rate changes transmit with a 6-18 month lag. Fixed-rate debt isn't affected until refinancing, and investment decisions are locked in for years. [src3]
Misconception: Low interest rates are always good for business.
Reality: Persistently low rates can signal economic weakness, compress bank margins, encourage excessive leverage, and create asset bubbles. [src2]
