Over his tenure, Federal Reserve Chair Jerome Powell oversaw significant shifts in interest rates and consumer pricing, impacting everything from savings yields to borrowing costs. The Federal Open Market Committee (FOMC) adjusts key rates based on economic data, influencing consumer spending power and debt servicing costs.
Federal Reserve Rate Movements
- Rate Adjustments: During his eight years, the FOMC raised the key overnight lending rate 15 times and lowered it 11 times.
- Current Stance: The FOMC recently decided to maintain the current rate, which stands 2.25 percentage points higher than the rate recorded in March 2018.
- Rate Swings: The rate has fluctuated widely, ranging from a low of 0% to 0.25% during the pandemic to a high of 5.25% to 5.50% when combating inflation.
Changes in Consumer Prices (Inflation)
- Overall Growth: According to the Bureau of Labor Statistics CPI calculator, the overall consumer price index grew by 32% during Powell's term (comparing March 2018 to the current March).
- Historical Context: While substantial, this 32% increase is not the highest recorded over comparable eight-year periods; the period between March 1973 and March 1981 saw a 104% rise.
Earning on Savings: Yield Comparison
Interest rates on savings products have shown marked variation, offering consumers several avenues for returns:
- High-Yield Savings Accounts (HYSA): While traditional brick-and-mortar yields remain low (often below 0.5%), online HYSA rates have shown improvement. As of a recent report, the average online savings account APY was 3.43%, with top deals reaching 4.2% to 4.4%.
- Money Market Accounts (MMA): These accounts offer yields higher than standard savings accounts. The average MMA yield increased from 0.15% in March 2018 to 0.51% in March of the current year, with top deals reaching 3% to 4%.
- Certificates of Deposit (CDs): Locking funds into a CD can yield better returns. The average one-year CD rate rose from roughly 0.5% in March 2018 to 1.92% currently, with brokerage options offering yields between 3.8% and 4.25% for one-year terms.
Costs of Debt: Borrowing Rates
Borrowing costs are influenced by the Fed's actions, though often with a lag. Rates for different debt types show distinct trends:
- Credit Cards: The average credit card rate increased from 16.84% in March 2018 to 19.57% recently. Store-based retail card APRs showed a steeper rise, from 25.64% in 2018 to 30.14% in 2025.
- Mortgages: The 30-year fixed rate mortgage rate rose from 4.44% in mid-March 2018 to 6.23% recently.
- Home Equity Lines of Credit (HELOC): The average variable rate for a HELOC increased from 5.77% in March 2018 to over 7% currently.
- Automobile Loans: Rates for new and used vehicles have risen significantly. For instance, a new car loan average APR increased from 5.7% (March 2018) to 7% (March 2026), leading to higher monthly payments and total interest paid.
