The Reserve Bank of Australia is expected to raise interest rates Tuesday by another 0.5 percentage points on the back of a “fully employed labor Market, a massive inflation overshoot and the fact that financial conditions are still highly accommodative,” Goldman Sachs chief economist for Australia and New Zealand Andrew Boak said.

Boak told CNBC’s “Squawk Box Asia” markets do not expect the central bank to soften its position on reining in inflation when it announces its rate decision at 2:30 p.m. Australian Eastern Standard Time.

“I think markets will be particularly sensitive to any sort of signal the RBA is thinking about stepping down the pace of tightening to say 25 basis point increments,” Boak said.

“I think key language will be retained around expecting to tighten further over the coming months. But also the caveat that policy is not on a preset path.”

There are risks with continued interest rate lifts such as the “disorderly unwind in the housing market” but Boak says “that is not our central scenario.”

Russian energy minister Nikolai Shulginov said the country will ship more oil to Asia in response to price caps on its oil exports, Reuters reported.

“Any actions to impose a price cap will lead to deficit on (initiating countries’) own markets and will increase price volatility,” he told reporters at the Eastern Economic Forum in Vladivostok, according to Reuters.

Last week, the G-7 economic powers agreed to cap the price of Russian crude to punish Moscow for its unprovoked invasion of Ukraine. Before the invasion, Russia exported approximately half of its crude and petroleum product exports to Europe, according to the International Energy Agency.
