In its six-monthly World Economic Outlook, released on Tuesday, the fund tipped Australia's economy to grow 1.9 per cent this year and 1.6 per cent in 2027, a pace exceeded only by the US, Spain, Singapore and New Zealand.
At that level of growth, unemployment is forecast to rise from 4.4 per cent this year to 4.7 per cent in 2027. Almost all other developed nations are expected to see no change or a small fall in unemployment over the same period. The number of Australians out of work could approach 800,000 by 2027, according to the forecasts.
Both growth forecasts are 0.1 of a percentage point lower than the fund's April projections.
Globally, the IMF expects the world economy to expand 3.1 per cent this year before accelerating to 3.4 per cent in 2027. Global inflation is expected to hit 4.7 per cent this year, driven largely by a surge in commodity prices including oil and food, before easing to 4.1 per cent.
The fund warned that the good luck that helped the world economy ride out the turmoil caused by the US-Israel war against Iran could soon run out, naming the AI boom and soaring government debt as growing risks to all nations.
