This is normal and healthy for the economy. For the average consumer, it signals the cost of credit is going to rise near term. For consumers that can qualify and can benefit from a refinance, they should pull the trigger on that decision. My advice is to focus on a lender than can close fast given a lost lock or expired lock will re-price at a higher level.
A steepening yield curve typically indicates investor expectations for 1) rising inflation 2) stronger economic growth (since improving growth causes the demand for longer-term capital to increase even as the Fed maintains a low-rate policy).
