Australian government bonds could be the among the big losers in a post-Trump world. With near-zero interest rates in major economies from the US to Japan, investors have plowed into Aussie bonds in recent years, which are the highest yielding among AAA-rated countries. But they could be challenged if bond yields globally continue to climb and the US Federal Reserve starts raising interest rates, says Su-Lin Ong, chief economist at RBC Capital Markets in Sydney. "Global capital now has more choice," she says and forecasts the spread between 10-year Australian and US government bonds to widen in coming weeks. 10-year Australian government bond yields were last trading at 2.66% Wednesday.
