Meanwhile, Federal Open Market Committee (FOMC) on Wednesday had indicated that rate hikes could come as soon as 2023, after signaling in March that it saw no increases until beyond that year. The latest projections from Fed officials suggest interest rates will be increased to 0.6 per cent in 2023 compared to previous projections indicating rates would remain at near-zero levels. Seven officials expect a rate hike as soon as 2022.
The Fed also raised its headline inflation expectation to 3.4% for 2021, a full percentage point higher than the March projection, but the post-meeting statement continued to say that inflation pressures are transitory.
