Barclays reported stronger quarterly profits fueled by its resurgent investment banking division, while pledging to return £15 billion to shareholders through dividends and buybacks. The British bank's turnaround follows years of restructuring efforts to streamline operations and improve capital efficiency.

Improved trading revenues and dealmaking activity powered the results, marking a reversal from recent struggles in Europe's banking sector. The investment bank outperformed rivals by gaining market share in fixed income and equities trading during volatile market conditions.

The £15 billion capital return plan represents one of London's largest shareholder commitments this year. Shares rose 3% in early trading as investors welcomed both the earnings beat and accelerated payouts. Analysts suggest the results demonstrate CEO C.S. Venkatakrishnan's success in rebalancing business units.
