Think of it this way: when the Fed signals it might slow down its rate cuts, or that the economy isn't out of the woods yet, investors who buy mortgage-backed securities get a bit more hesitant.
My take on this is that if you've been on the fence about refinancing, and your current rate is significantly higher than the current offerings, it might be wise to seriously consider moving forward.
While the Federal Reserve has signaled a shift towards supporting economic growth, the path forward for interest rates is anything but smooth.
