Sean Callow, Research Analyst at Westpac, suggests that the markets also need to contend with summer political event risk from the US presidential campaign. Key Quotes “This week’s easy victory for Ted Cruz in the Wisconsin primary has seen oddsmakers trim the chances of Donald Trump winning the nomination.

A contested convention has not occurred since 1976.

Since the Wisconsin vote, such talk has picked up. Anything seems possible in this year’s wild campaign so we can’t dismiss the chance (though low) of neither Trump nor Cruz representing the Republicans. A centrist choice such as Kasich or even House Speaker Paul Ryan could well spark a burst of optimism in US markets.
