By William Schomberg, Lawrence White and Suban Abdulla LONDON (Reuters) -The Bank of England warned on Friday that higher trade barriers could hit global growth and feed uncertainty about inflation, potentially causing volatility in financial markets and pushing up borrowing costs for businesses and consumers.

Surging government debts threaten to hammer the British economy and drive up borrowing costs for households, businesses and the Treasury, the Bank of England has warned.

Global trade barriers threaten global economic growth and unsettle the stability of the UK’s financial system.

More work is needed to tackle risks outside the banking sector, according to a Bank of England study which found that a market crisis would be amplified by fire sales of assets by pension funds, hedge funds and other investors.
