Energy costs and supply chain hiccups are the main culprits right now - oil prices jumped, shipping stayed elevated, and stuff like groceries and rent just haven't come down the way people hoped. You're right that this pressures the Fed to keep rates higher longer, which ripples into mortgages and credit cards. One thing most folks overlook: if you've got variable-rate debt (credit cards, adjustable mortgages, HELOCs), locking in fixed rates now before another hike hits makes sense, but if you're sitting on cash savings, this is actually when high-yield savings accounts become genuinely useful - you're getting 4-5% returns just for parking money there, which hedges inflation pretty well.
