What is a High-Yield Savings Account? ▼
A high-yield savings account is a type of savings account that pays a significantly higher interest rate (APY) than standard savings accounts. These are often offered by online banks that have lower overhead costs than traditional brick-and-mortar banks.
Are online savings accounts safe? ▼
Yes, as long as the online bank is FDIC insured. This provides the same level of protection (up to $250,000 per depositor) as a traditional bank. Always check for the FDIC logo on the bank's website.
Can I withdraw money from a savings account anytime? ▼
Yes, but there are limits. Federal Regulation D used to limit certain withdrawals to 6 per month, though this has been suspended. However, individual banks may still enforce transaction limits or charge fees for excessive withdrawals.
Do savings rates change? ▼
Yes, savings rates are variable and can change at any time based on the Federal Reserve's benchmark interest rates and market conditions. Unlike a CD (Certificate of Deposit), your savings rate is not locked in.
