Top Australian Investment Banks

Large-scale and complex financial transactions always require a trusted intermediary. These top Australian investment banks can easily serve as such.

Top Australian Investment Banks

An investment bank is a specific institution able to process and assist in large financial transfers like those involved in corporate mergers and acquisitions (M&A), as well as initial public offerings (IPOs). Besides, these banks may offer proprietary trading or trading securities, as well as lending and restructuring-related services. Many global investment banks are situated in the US (Goldman Sachs, JPMorgan Chase, Citibank, etc) where the annual number of business deals is staggering. What about Australia?

In Q2 2022, Australia witnessed 348 M&A transactions with US$27.3 billion in total transaction value. In the first half of 2023, the country recorded 615 IPOs with US$60.9B capital raised. Although the numbers have declined compared to the more robust 2021, there’s still an obvious need for a strong proposition from both local and global investment banks.

Here is a list of the leading Australian investment banks able to handle both local and global transactions on a large scale. It largely includes domestic institutions though most major banks headquartered in other countries also offer investment banking services to Australian businesses.

National Australia Bank (NAB)

This domestic bank has a global offering, being able to support its Australian customers globally. NAB expertise revolves around debt capital markets, real asset investments, fixed-income solutions, asset servicing and regulation. Besides, it is one of the few banks in Australia providing total capital solutions like trade and working capital, debt capital markets, and transactional banking to Australian businesses.

Moreover, the bank’s international networks of institutional, wealth, private and retail institutional investors allow its corporate customers to access global pools of liquidity. In addition, NAB has a full distribution across the US public, US private placement (USPP) and Australian Residential Mortgage-Backed Security issuance.


The Commonwealth Bank of Australia (“CBA”) Group is the largest bank and by far the best-known financial services brand in Australia. CBA is one of the largest listed companies on the Australian Stock Exchange included in the Morgan Stanley Capital Global Index. CommBank is also Australia’s largest bank by market capitalisation.

This multinational bank operates across New Zealand, Asia, the US and the UK.

The leading Swiss bank UBS which has recently acquired Credit Suisse is now a banking group overseeing $5 trillion of assets, with a leading position in key markets. Being a major financial player, UBS deals with M&A transactions for global joint ventures, inbound public takeovers, or cross-border deals.

Side note

As you can see from the Australian investment banks list, top local financial institutions provide some form of investment activities, like access to capital markets. However, the local Big Four does not focus much on M&A activities. For these deals, many Australian businesses turn to global banking groups like UBS. American banking giants such as Goldman Sachs, JPMorgan Chase and Citibank also provide investment banking services in Australia, though we didn’t include them in the list, as these household names are already well-known among businesses heading towards IPO or mergers across the globe.
