If an "unexpected world events" occurs, the volume/liquidity will most certainly increase. Another example is the Forex Market that's open 24/7 around the world. As one major forex market closes, another one opens. According to GMT,   for instance, forex trading hours move around the world like this:   available in New York between 01:00 pm – 10:00 pm GMT; at 10:00 pm GMT   Sydney comes online; Tokyo opens at 00:00 am and closes at 9:00 am   GMT; and to complete the loop, London opens at 8:00 am and closes at   05:00 pm GMT. This enables traders and brokers worldwide, together   with the participation of the central banks from all continents, to   trade online 24 hours a day. src
