Why we expect EURUSD SPX to keep falling.

Dear fellows. In this short video we present our case that EURUSD tracks US10Y since 2020 on an inverse relationship. We also expect the yield curve to keep steepening, and by assuming Fed funds rate "higher for longer", US10Y is expected to rise further.
Higher US10Y, thus, implies in lower EURUSD and SPX, as well as other major market indexes.
The particular dynamics of each does not ensure a day to day follow up, however, eventually they do catch up.
Thank you very much for your time. Critics and suggestions are welcome.
Best regards.
