Developments surrounding the global coronavirus outbreak continued to be watched on Thursday.
The Reserve Bank of Australia (RBA) announced Thursday a "comprehensive package," including a reduction in the cash rate target to 0.25%, to support the country's economy as it grapples with the impact of the virus.
"At some point, the virus will be contained and the Australian economy will recover," RBA Governor Philip Lowe said in a statement. "In the interim, a priority for the Reserve Bank is to support jobs, incomes and businesses, so that when the health crisis recedes, the country is well placed to recover strongly."
Meanwhile, the U.S. Federal Reserve invoked its emergency authority on Wednesday to create a backstop for prime money market mutual funds. The new Money Market Mutual Liquidity Fund will provide loans to financial institutions to buy assets from prime money market funds.
Stocks in the region had earlier gotten a boost after the European Central Bank announced Wednesday a new Pandemic Emergency Purchase Programme that will use €750 billion (approx. $821 billion) to purchase securities to help support the European economy.
"The ECB will ensure that all sectors of the economy can benefit from supportive financing conditions that enable them to absorb this shock," the central bank said in a release. "This applies equally to families, firms, banks and governments. The Governing Council will do everything necessary within its mandate."
