San Francisco Fed President John Williams to speak at 3:30 pm ET (2030 GMT)

Up next on the Fed calendar is John Williams in his first comments since the strong retail sales and CPI numbers.

His most-recent comments were on Feb 3, when he said:

"There are some arguments for, potentially, if the data are coming in consistent with my view, that March makes sense. First of all, if you're going to have three rate increases, you have to have them at some point."

He sounded then like he was in favour of moving sooner rather than later.

"There is some optionality to moving sooner rather than waiting this year," he said. "Three rate increases, like I said, it's a reasonable guess, a reasonable perspective to have as a base case. But honestly, I think there's a lot of potential that this economy is going to perhaps get more of a boost than the base case."

Earlier today, the SF Fed also published Williams' latest economic letter. In it, he said that low rates are like be very persistent due to aging populations and low productivity.

Williams also fretted about a world where long-run growth is 3%.

"In a low r-star world, what were once called 'extraordinary' policies -- like zero or negative interest rates, forward guidance, and balance sheet policies -- are likely to become the norm," he wrote.
