$FED Interest rates = what the central bank sets.
Bond yields = what the market demands.
Both affect borrowing costs — but come from different sources. Although related, things which are different are not the same.
Bond yields can rise even when interest rates stay flat, tightening financial conditions. Higher yields mean higher mortgage rates, higher corporate borrowing costs, and higher preferred share payouts.
When people say “rates are rising,” they often mean bond yields, not central bank rates. And along with rising oil prices, there rising bond yields are what are weighing on the market right now.
