The Australian dollar fell sharply on political turmoil across the Tasman resulting in Prime Minister Malcolm Turnbull's resignation today.
However, it recovered some of those losses when Morrison, who will be Australia's sixth prime minister in less than 10 years, beat former home affairs minister Peter Dutton and Foreign Minister Julie Bishop to take the nation's top job.
"PM Morrison is the most market-friendly option, having successfully negotiated through multiple portfolios such as Social Security, Border Security, and more recently presiding over a substantial improvement in the budget balance as Treasurer," said Annette Beacher, chief Asia-Pac macro strategist for TD Securities.
"This was a bit of a relief rally ... markets are viewing Morrison as a bit of the status quo outcome," said ANZ Bank New Zealand senior macro strategist Phil Borkin.
Investors will now focus on Federal Reserve chair Jerome Powell who is due to give a speech entitled Monetary Policy in a Changing Economy at the Federal Reserve Bank of Kansas City Economic Policy Symposium, Jackson Hole, Wyoming.
