SINGAPORE: The dollar traded just below a 16-month high versus a basket of peers, benefiting from save-haven flows as investors shunned riskier assets because of political uncertainties in Europe and fears of a global economic slowdown.
Investor confidence has been eroded by bitter trade tensions between the United States and China, fears of a no-deal Brexit, and a standoff between Rome and the European Union over Italy's deficit-deepening budget.
Added to that litany is a view that corporate earnings growth has peaked amid rising borrowing costs.

The Japanese yen was the only major currency to gain versus the dollar overnight as risk aversion caught hold of investors. It traded at 113.66 on Tuesday, as the greenback lost 0.16 per cent versus the yen.
The yen touched a six-week low of 114.20 on Monday before the safe-haven bids kicked in.
The dollar has been preferred over the yen due to the diverging monetary policies of the Fed and the Bank of Japan, which is expected to retain its ultra-loose monetary policy settings for some time in the face stubbornly sluggish inflation.
But analysts believe that the yen will strengthen thanks to its safe-haven status if global risk sentiment worsens.
"The yen will now have a greater safe haven pull than the dollar if equities witness a further correction. We see dollar/yen downside in that scenario," added Twidale.
