"We are seeing the US 10-year unwind a bit and generally, there is a weak US dollar across the board," said Martin Rudings. The risk is that the yield on 10-year US Treasuries falls to 2.65 per cent and "that will weaken the US dollar if that eventuates", he said.
Overall, 10-year US Treasuries are "probably overcooked a little bit and the market needs to relax that trade", Rudings said.
Markets will also be keeping a close eye on the Fed's favoured measure of inflation, the core personal consumption expenditure or PCE index due early Thursday in the US.
