The risk-free rate is also a required input in financial calculations, such as the Black–Scholes formula for pricing stock options and the Sharpe ratio. Note that some finance and economic theories assume that market participants can borrow at the risk-free rate; in practice, very few (if any) borrowers have access to finance at the risk free ...
Traditional inflation-free rate of interest for risk-free loans: 3-5%; Expected rate of inflation: 5%; The anticipated change in the rate of inflation, if any, over the life of the investment: Usually taken at 0%; The risk of defaulting on a loan: 0-5%; The risk profile of a particular venture: 0-5% and higher
The approach arises since the evolution of the option value can be modelled via a partial differential equation (PDE), as a function of (at least) time and price of underlying; see for example the Black–Scholes PDE. Once in this form, a finite difference model can be derived, and the valuation obtained. [2]

Since prepayments typically rise as interest rates fall and vice versa, the basic (pass-through) MBS typically has negative bond convexity (second derivative of price over yield), meaning that the price has more downside than upside as interest rates vary. The MBS-holder's exposure to borrower prepayment has several names: call risk; extension risk
The Black formula is similar to the Black–Scholes formula for valuing stock options except that the spot price of the underlying is replaced by a discounted futures price F. Suppose there is constant risk-free interest rate r and the futures price F(t) of a particular underlying is log-normal with constant volatility σ.
A risk-free bond is a theoretical bond that repays interest and principal with absolute certainty. The rate of return would be the risk-free interest rate. It is primary security, which pays off 1 unit no matter state of economy is realized at time +. So its payoff is the same regardless of what state occurs.
The lowest of all is the risk-free rate of return. The risk-free rate has zero risk (most modern major governments will inflate and monetise their debts rather than default upon them), but the return is positive because there is still both the time-preference and inflation premium components of minimum expected rates of return that must be met ...
