Such an outcome could reduce global economic growth by 0.6% annually in the first half of this year, and raise consumer prices by 1% annually, Kasman said. He warned that a widespread and sustained conflict could send the price of oil above $120 a barrel and lead to a global recession.

The Fed’s top measure of core inflation expires on Friday and is forecast to hold at 3.0%, well above the central bank’s 2% target, and analysts see the risk of an even higher number.

For the Bank of England, markets moved to price in just a 40% chance of one facility versus two or more cuts prior to the start of the Middle East conflict.
