The global crude oil market is critically important in many respects. It is the fuel that drives the global economy and, as such, is the focus of climate policies. Moreover, crude oil is the basis of a tradable financial asset. It is therefore connected to several outstanding macroeconomic developments of recent years, including financial market fluctuations, the financial crisis and the exceptional conduct of monetary policy. This book investigates the impacts of monetary policy and the financial system on the global crude oil market. Furthermore, it outlines how monetary policy may also be used to guarantee stability and to contribute to ecological sustainability.
