Today is going to be a big day for the markets as we get the US CPI and the FOMC decision on the same day. The last time it happened was in June 2020.
I would argue that the US CPI will be the real mover as it will drive markets' expectations for the FOMC decision. Hot CPI and we can expect a sligthly hawkish Fed. Conversely, soft CPI and we can expect a neutral or slightly dovish Fed.
