on Wednesday, policymakers are all but certain to lift interest rates again in
an attempt to keep inflation at bay by raising borrowing costs. This will
likely mark the third quarter-point rate hike announced by Fed chair Janet
Yellen since last December. But if that's the case, why have mortgage
rates sunk to near a seven-month low, from 4.32% at the end of December to just
3.89% in June?
