2008 crisis was a major financial crisis but it was far from unique. William De Vijlder gives an account of some of the most significant economic crises with a particular focus on the 20th century. He shows how central banks tried to adjust to economic circumstances and fight financial instability. It is to be noted that financial stability has been one of the main concerns of central banks since the 2000s. The 2008 financial crisis reinforced the ambition of stability with notably the set-up of international organisations such as the FSB (Financial Stability Board) in 2009.
