Following regulatory approval, Xinja Bank plans to offer its new platform, called Dabble, through its banking app, giving investors access to more than 3,000 US stocks and ETFs.

Neobank said it will charge a flat monthly subscription fee of $8 for unlimited trading in addition to a 1% foreign exchange fee per trade, excluding brokerage fees.

Dabble will also offer fractional trading, where investors will be able to buy fractions of shares.

Xinja Bank founder and CEO Eric Wilson said Dabble will give customers access to alternative investment options, especially when interest rates remain low.

Neobank signaled it was feeling the pinch from the RBA's cash rate move in May when it cut the interest rate on its Stash savings account from the previous 2.25% to 1.8%.

"We offer [low-cost] easy access through the Dabble platform and the option to purchase a fraction of a share, which we hope will open up markets and investments for people looking to grow their wealth through [long-term]' said Mr Wilson.

"The shares of many US-listed companies are trading at very high prices, which excludes many people from the market. So while brand recognition for leading American companies is very high, few people want to invest directly. And entering the market was not easy.

"We want to keep costs down and make it easier to bring these opportunities to Australians."

Xinja customers will only be able to invest as much money as is currently in their bank account, and those who engage in pattern day trading, buying and selling stocks within a day, for four days in a row, will have their account blocked.

Stocks related to tobacco and weapons are also excluded from the platform.

Xinja received its full banking license in September.
