With the onset of the financial crisis in late 2007, the market conditions changed radically and the elementary pricing procedure used among practitioners became unreliable and obsolete. This necessitated a change in the methods used in pricing financial products. We discuss post-credit crunch paradigm shift from single-curve to the multi-curve setting. We first present the single curve and explore techniques such as the construction of single yield (spot) curve, and show how we obtain yield measures from the curve and use them to price interest rate swaps and bonds. We then study the multi-curve pricing framework and compare the two pricing methodologies against the practice currently used in Kenya to price bonds and give recommendations.
