Everything!  Just kidding, but no seriously basically everything.  Although, when the Fed says it is moving interest rates, the reality is it isn’t directly changing your mortgage rate or anything like that.  However, since the rate banks lend to each other goes up the ripple effect is what matters.  Essentially, since the short-term high-quality baseline interest rate has been moved, then everything from there changes too.  Sooooo nearly all new debt gets more expensive, including new mortgages, car loans, college loans, credit card loans, and even existing variable interest loans go up.  If it is not fixed it goes up.  What this also means is it is more expensive for businesses to borrow funds for their projects.  The flip side of all this is bond interest rates will go up, as will your piddly savings account rates.  Thus, not all increases in interest rates are bad, but it is something to keep an eye on and a great planning opportunity.
