These four establishments essentially monopolize the entire banking industry—the 'Big Four' is an idiomatic name for the four central banks in many countries. In Australia, they are the National Bank of Australia, the Commonwealth Bank, Westpac, Australia, and the New Zealand Banking Group. In the UK: Barclays, HSBC, Lloyds Banking Group, and the Royal Bank of Scotland Group. And in the US, the "Big Four" are CitiGroup, JPMorgan Chase, the Bank of America, and Wells Fargo.
