Your guide to all the reasons markets are tanking

London/New York | Global markets have suffered a frightful October, with the latest tumble taking the FTSE All-World index's loss this month so far to a whopping 7.2 per cent — its worst performance since the peak of the eurozone crisis in 2012.

Of the global equity benchmark's 3,211 members, almost a third have now lost more than 20 per cent of their value this year in US dollar terms. Well over half are down at least 10 per cent, and as of the end of Tuesday (Wednesday AEDT), only 853 companies were still in positive territory for 2018.
