When you are global head of rates at a $1.7trn (€1.53trn) fund, you can not spend a month on the sidelines to avoid risks, no matter how big.

The UK’s EU referendum, a US Federal Reserve policy decision, an Organization of Petroleum Exporting Countries (Opec) meeting, and the prospect of another muddled Spanish general election are all due in June.

Like it or not, the biggest investors must take positions, particularly to spread their risk, according to David Tan at JP Morgan Asset Management in London.
