APYs at $10,000 USD, compared with the previous checked observation under the same account terms. Unchanged checks are skipped, so older changes stay visible. Dates show when we observed each rate, not necessarily when the bank changed it.
Zoomed APY scale · Dates in America/New_York. Dashed lines carry the last recorded APY forward between checks and through today; they are not continuous verification. Symbols mark observations. Blank space before an account’s first observation means no recorded history. Pending reviews or changed terms break lines; rates between checks are unconfirmed.
