What This Branch Covers

What to Check

• Nominal, real, natural, policy, market, or theoretical rate concept.
• Inflation expectation, currency, maturity, and compounding basis.
• Model assumption such as parity, fisher relation, liquidity preference, or loanable funds.
• Benchmark, instrument, or cash flow affected.
• Valuation, borrowing, hedging, or policy conclusion affected.

Common Mistakes

• Mixing nominal and real rates.
• Using a theory relationship as if arbitrage were guaranteed.
• Ignoring maturity, compounding, taxes, liquidity, and credit spread.
• Confusing benchmark rates with broad interest-rate theory.
