A historic winter storm in America that has pummelled the state of Texas has delivered a tailwind worth up to $300 million for Australian investment bank Macquarie Group, which will now notch up a jump in profit over the year that included the COVID-19 pandemic.

Macquarie, which has a significant energy and oil storage and trading business, said on Monday it was expecting its annual profit for the year through March to come in between 5 and 10 per cent higher than the previous year.
