"And we're expecting a further two times 25 basis point rate cut from ... the RBA. One in August, one in November, and that's probably something that should continue to undermine the Australian dollar as we move through to the end of this year."

Wall Street rally

Overnight on Wall Street, stocks jumped as the major indexes all rose more than 2% each on the day. The Dow Jones Industrial Average surged 512.40 points, or 2.1% to 25,332.18. The jumped 2.1% to 2,803.27 and the Nasdaq Composite surged 2.7% to 7,527.12. The major indexes had their second-best day of 2019.

The moves stateside came after U.S. Federal Reserve Chairman Jerome Powell signaled that the central bank was open to easing monetary policy to support the economy.

He said the central bank will "act as appropriate to sustain the expansion." He noted, however, the Fed does not know "how or when" global trade issues will be resolved. "We are closely monitoring the implications of these developments for the U.S. economic outlook," he added.

Powell's comments came amid increasing expectations for a Fed rate cut. The CME FedWatch tool indicated about a 90% chance of a September rate cut. Expectations for a second rate cut in December were also above 80%.

The Fed chair's speech "hit the right balance appeasing equity markets by confirming the Fed stands ready to act in order to sustain the current economic expansion if trade tensions hamper US economic growth," while also rejecting "the recent aggressive pricing of Fed rate cut expectations," National Australia Bank senior foreign exchange strategist Rodrigo Catril wrote in a note.

"I think chairman Powell has given a message to markets that is indicating that a rate cut is coming. This is in essence a very strong signal that the (Federal Open Market Committee) is ready to actually talk about cutting rates," Sarah Bloom Raskin, a former governor at the Federal Reserve, told CNBC's "Squawk Box" on Wednesday.

Trade developments

Investors also cheered comments made by the Chinese Commerce Ministry, which said in a post that the "differences and frictions between the two sides" should be dealt with through talks, according to a Google translation. Market watchers took those remarks as a sign of possible easing of trade tensions between Beijing and Washington after each country hiked tariffs on billions of dollars worth of each other's goods in May.

But, the post also said talks "need to be based on mutual respect, equality and mutual benefit."

U.S. Treasury Secretary Steven Mnuchin is set to meet with People's Bank of China Governor Yi Gang at a gathering of G-20 finance leaders this weekend in Japan, Reuters reported. The meeting would mark the first face-to-face meeting between the two countries in nearly a month, according to the news agency.

On the U.S.-Mexico trade front, Mexican Foreign Minister Marcelo Ebrard said Tuesday he expects both countries to find common ground on immigration and trade, despite U.S. President Donald Trump threatening to slap tariffs on all imports coming from Mexico. For their part, Republican lawmakers have indicated their opposition to the tariffs on Mexican goods. They have also hinted at blocking those levies if the president moves forward with them.
