This paper examines a simple basis risk model based on correlated geometric Brownian motions. We apply quadratic criteria to minimize basis risk and hedge in an optimal manner. Initially, we derive the Föllmer–Schweizer decomposition for a European claim. This allows pricing and hedging under...

Interest-rate volatility is known to be positively level dependent, i.e., to correlate positively with interest rate levels. However, recent research has provided compelling evidence that as interest rates rise, the amount of level dependence decreases. We advance this line of research by...
