Introduction
High‑yield savings accounts (HYSAs) have become a go‑to tool for anyone looking to earn more on idle cash without taking on market risk. Yet even the savviest savers can slip into habits that erode those gains. Recent data from the Federal Deposit Insurance Corporation shows that the average APY on top‑tier HYSAs hovered around 4.30% in early 2024, but many account holders are realizing far less because of avoidable oversights.
