  2. Interest rate parity - Wikipedia

    en.wikipedia.org/wiki/Interest_rate_parity

    Interest rate parity is a no-arbitrage condition representing an equilibrium state under which investors compare interest rates available on bank deposits in two countries. [1] The fact that this condition does not always hold allows for potential opportunities to earn riskless profits from covered interest arbitrage .

  3. Impossible trinity - Wikipedia

    en.wikipedia.org/wiki/Impossible_trinity

    The formal model underlying the hypothesis is the uncovered Interest Rate Parity condition which states that in absence of a risk premium, arbitrage will ensure that the depreciation or appreciation of a country's currency vis-à-vis another will be equal to the nominal interest rate differential between them. Since under a peg, i.e. a fixed ...

  4. Fisher equation - Wikipedia

    en.wikipedia.org/wiki/Fisher_equation

    The Fisher equation plays a key role in the Fisher hypothesis, which asserts that the real interest rate is unaffected by monetary policy and hence unaffected by the expected inflation rate. With a fixed real interest rate, a given percent change in the expected inflation rate will, according to the equation, necessarily be met with an equal ...

  5. Hull–White model - Wikipedia

    en.wikipedia.org/wiki/Hull–White_model

    In there it was shown how the said partitioning enables capturing statistically significant time changes in volatility of interest rates. following the said approach, Orlando et al. (2021) [7]) compares the Hull–White model with the CIR model in terms of forecasting and prediction of interest rate directionality.

  6. Mundell–Fleming model - Wikipedia

    en.wikipedia.org/wiki/Mundell–Fleming_model

    In a system of fixed exchange rates, central banks announce an exchange rate (the parity rate) at which they are prepared to buy or sell any amount of domestic currency. Thus net payments flows into or out of the country need not equal zero; the exchange rate e is exogenously given, while the variable BoP is endogenous.

  7. Forward exchange rate - Wikipedia

    en.wikipedia.org/wiki/Forward_exchange_rate

    The forward exchange rate depends on three known variables: the spot exchange rate, the domestic interest rate, and the foreign interest rate. This effectively means that the forward rate is the price of a forward contract, which derives its value from the pricing of spot contracts and the addition of information on available interest rates. [4]

  8. Fisher effect - Wikipedia

    en.wikipedia.org/wiki/Fisher_effect

    The nominal interest rate is the accounting interest rate – the percentage by which the amount of dollars (or other currency) owed by a borrower to a lender grows over time, while the real interest rate is the percentage by which the real purchasing power of the loan grows over time. In other words, the real interest rate is the nominal ...

  9. Short-rate model - Wikipedia

    en.wikipedia.org/wiki/Short-rate_model

    Tree returning the OAS (black vs red): the short rate is the top value; the development of the bond value shows pull to par clearly.. A short-rate model, in the context of interest rate derivatives, is a mathematical model that describes the future evolution of interest rates by describing the future evolution of the short rate, usually written .
