An 18-month certificate of deposit (CD) offers higher returns than regular savings accounts with the same level of safety due to FDIC or NCUA protection up to $250,000. They are attractive for those seeking to avoid stock market volatility and prefer a fixed interest rate for a relatively short duration. Consider CDs from First Internet Bank (5.04% APY), Alliant Credit Union (4.90% APR), MYSB Direct (5.15% APY), TAB Bank (5.00% APY), Ally Bank (4.45% APY), Capital One (4.45% APY), Prime Alliance (4.75% APY), Marcus by Goldman Sachs (minimum deposit of $500), Vio Bank (4.50% APY), and LendingClub (5.00% APY). Weigh the pros and cons, such as fixed returns, FDIC insurance, and limited liquidity, to determine if an 18-month CD aligns with your financial goals.
