Bank of England Governor Mark Carney says the central bank will not be predicting the likely economic consequences of a British vote to leave the European Union.

Carney told a committee of lawmakers Tuesday that "we are not making a judgment about the potential outcome of the referendum ... or an assessment of the potential consequences of a leave vote."

The heads of almost 200 firms have warned that leaving the EU would "deter investment, threaten jobs and put the economy at risk."

The looming June 23 vote has caused jitters for Britain's pound, which hit a seven-year low of $1.4058 Monday before rallying to just above $1.41.

Carney said the currency's volatility has "spiked to levels consistent with around the height of the Scottish referendum" on independence in 2014.
