Savings and chequing deposits
are comprised of regular savings and chequing accounts (domestic and U.S.) and premium savings accounts. Premium savings accounts (PSAs) are made up of tiered savings accounts and high-interest savings accounts. Tiered savings accounts offer escalating interest rates tied to the account balance, with $5,000 typically required to earn a premium rate. High-interest savings accounts (HISAs) pay a high rate of interest from the first dollar deposited.
