Assistant Coroner Shirley Radcliffe has ruled that Mr Angad Paul had killed himself while "the balance of his mind was disturbed".
The steel company boss felt responsible for the loss of 450 jobs at the company Caparo, announced in October 2015, amid the collapse of steel prices, the inquest heard.
Radcliffe said: "I shall record that Angad Paul has died as a result of severe head injuries, and on November 8 2015 he jumped from the balcony of his home address. He had been suffering from severe agitated depression."
Paul jumped to his death from the balcony of his penthouse apartment after becoming overcome with depression following the collapse of his business. He was concerned about how he was going to pay the mortgage, and, feeling "absolutely powerless", believed people would think he was responsible for the failure of the company.
Angad was the son of Lord Swraj Paul, who founded the business in 1968 with a £5,000 loan and helped it grow into a multibillion-pound enterprise. He had run the Caparo Industries subsidiary since taking over from his father in 1996.
Westminster Coroner's Court heard that Angad allegedly told colleague Denis Krupnov that "although he was CEO of the company, he had no real control of the company affairs".
He added that his father - who attended the inquest - "took all the decisions".
Angad had become very depressed when the company was put into administration, and, although he believed it was the "wrong decision", there was nothing he could do, the court heard.
