What is becoming evident is the move by smaller institutions into the high interest space, branchless space, recognising the national coverage they can achieve quickly.  Wilmington is a 10 Bn dollar bank.

wtdirect.com is a separate brand, and is not mentioned on the main bank page.

The latest top bidder on Google (see End Notes) is WT Direct , a new direct banking brand from Wilmington Trust. Its sole product is a 5.26% APY savings account. To encourage trial, the bank pays the advertised rate on any balance for the first 60 days. On day 61, the rate drops 466 basis points to 0.60% unless you’ve stored $10,000 or more in the account. The bank clearly discloses both rates.
