Financial crisis, global conditions, and regime changes
This column examines the use of key global market conditions to assess financial volatility and the likelihood of crisis. Using Markov regime-switching analysis, it shows that the Lehman Brothers failure was a watershed event in the crisis, although signs of heightened systemic risk could be detected as early as February 2007.

The international community has called for the IMF to deepen its work on systemic risks and early warning signals. While there are currently many different research strands, this short column empirically examines the role that global market conditions play in detecting systemic risk. We adopt regime-switching models using variables that proxy for global market conditions – Chicago Board Options Exchange Volatility Index (VIX), TED spread (the difference between LIBOR and Treasuries), and US dollar-euro foreign exchange swap rate. For instance, the Lehman Brothers collapse on 15 September 2008 was a watershed event that rapidly spilled over to emerging market countries, sharply increasing uncertainty across asset markets, a scramble for US dollars with the breakdown of the carry trade, and the need for financial institutions to refinance their US dollar positions. The regime-switching models indicate a move towards a high volatility state before the Lehman episode, which are consistent with elevated systemic risks in the financial system. We first look qualitatively at the behaviour of some global market variables during the financial crisis before presenting the formal findings of the regime-switching models.
