We generate a yield curve that approximates the risk-free yield curve. Since government bonds are considered virtually default-free, the GOVI benchmark bonds (a selection of the most liquid fixed rate government bonds) form a term structure of nearly risk-free interest rates. Using this term structure, a smooth continuous yield curve is fitted relating an approximated risk-free interest rate to any bond duration term.
