Bank of England Governor Mark Carney has warned that central banks shouldn't be relied upon to prop up the global economy in the event of an all-out trade war.

Carney compared the uncertainty on trade to the bank's effort to bolster the U.K. economy ahead of Britain's departure from the European Union.

He told a summit in northern England on Thursday that "in a general trade war, it is unlikely that global financial conditions would prove as robust, or that monetary policy could be as supportive."

He also offered a swipe at American rhetoric on trade, saying "talk and tweets" was already taking a toll, with signs on uncertain trading was dampening activity.

Some surveys of global export orders and manufacturing output have fallen back from earlier this year.
