Twenty of the largest listed companies in the world are sitting on a combined cashpile of $570bn, demonstrating how some of the world’s biggest groups retain substantial firepower in the current downturn.

However, only 29 of the top 100 global companies by market value have net cash, according to analysis by the Financial Times. But those that do should be in a strong position in a severe downturn that is causing companies to scramble to conserve cash.

The list is led by four financial institutions with Warren Buffett’s Berkshire Hathawayat the top with $106bn in net cash, defined as cash and short-term investments or marketable securities minus debt. Strikingly, the next three positions are filled by Chinese banks with Bank of China, ICBC and China Construction Bank having $101bn, $89bn and $82bn, respectively, according to data from Bloomberg.
