Reserve Bank of Australia keeps rates on hold
On Tuesday afternoon. the Reserve Bank of Australia announced that it was going to continue keeping the cash rate unchanged at 1.50 percent, continuing a more than two-year streak.
"It's getting hard to come up with anything new to say on this!," Shane Oliver, head of investment strategy and chief economist at AMP Capital, said in an afternoon note.
Oliver did, however, acknowledge that the Australian central bank's decision was "as it should be."
"Raising rates just to get rates back to more "normal levels", or so as to be able to cut them later if needed, would make no sense and would be bad for the economy," he said.
South Korea's job woes
On Tuesday morning, South Korea's Finance Minister Kim Dong-yeon warned that the country could see annual employment losses for the month of September, after the jobless rate hit an eight-year high in August.
Speaking with CNBC's "Squawk Box" on Tuesday, Standard Chartered Bank Korea's Head of Economic Research Park Chong Hoon said South Korea's employment woes were "structural" in nature, with issues such as a change in demographics and the retirement of baby boomers.
"It's going to be deeper," Park said. "That kind of weak job market will continue to trend."
