"The dollar hit two-month highs against the euro and sterling on Friday as rising bond yields continued to put pressure on global equity markets.
The dollar rose 0.3 per cent to $1.3380 against the euro and climbed 0.5 per cent to $1.9675 against the pound.
“In bouts of risk aversion the dollar has in recent times tended to do well as US investors who have been active in investing abroad either stop or reverse some of these outflows,” said Derek Halpenny, economist at Bank of Tokyo-Mitsubishi UFJ.
The dollar also advanced against the yen, climbing 0.2 per cent to Y121.20.
However, the yen rose against the euro and sterling, climbing 0.2 per cent to Y162.14 and 0.4 per cent to Y238.44 respectively.
Analysts said rising risk aversion had prompted investors to trimmed back carry trade positions, in which the purchase of riskier high-yielding assets is funded by selling low-yielding currencies such as the yen.
However, Adrian Schmidt at Royal Bank of Scotland said the sell-off in carry trades had so far been quite modest.
“The rise in bond yields in recent days and the decline in equity markets and rise in volatility that has resulted is negative for the pure carry trades, but has also led to further widening in yield spreads in favour of the high yielders, and this is moderating the impact,” he said.
Indeed, the Australian and New Zealand dollars, where yields have risen most dramatically, both advanced against the yen, rising 0.4 per cent to Y101.93 and 0.3 per cent to Y90.99 respectively.
However, Hans Redeker at BNP Parisbas said if equity markets continued to push lower, yen selling pressure was unlikely to persist. “There comes a point when rising bond yields are negative for the carry theme,” he said. “This takes place when investors shift their focus from the positive growth story to that of inflation.”
