Broad equity market declines in Asia and Europe and a lower open on Wall Street threatened to spoil the longest winning streak for MSCI’s global stock index since 2003.

Japan’s Nikkei index saw a wild two per cent swing after hitting its highest since 1992 and Europe’s main indexes were firmly in the red as tech and commodity stocks tumbled and as Brexit talks resumed amid low expectations in Brussels.

MSCI’s all-country equity index is clocking year-to-date gains of almost 19 per cent.

The dollar index, which tracks the greenback versus a basket of six key currencies, fell 0.202 points or 0.21 per cent, to 94.664.
