JPMorgan Chase and American Express both plan to sell ordinary shares as a way to satisfy conditions for repaying the money they received under the US government’s troubled asset relief programme.

JPMorgan, which received $25bn in Tarp funds, said on Monday it hoped to sell $5bn in equity in an offer that could be priced as early as today. Amex said it also planned to sell $500m of common stock to help repay $3.4bn of bail-out funds.
