📊 Full 5-tier MMA data — drawn from 12,704 verified APY quotes from 2,378 institutions across all 50 states.

NATIONAL — Money market account rates were mixed for the week ending April 20, 2026, with three of four comparable tiers gaining and the high-yield tier holding nearly flat. This release also introduces Jumbo MMA as a fifth tier, averaging 1.727% APY across 17 institutions and 437 verified rate quotes. Credit union money market posted the week’s largest gain, rising 0.016 points to 1.233% across 1,381 institutions. High-yield bank MMAs held near last week’s level, slipping just 0.003 points to 3.030% across 299 institutions.

The newly added Jumbo MMA tier averages 1.727% APY across 17 institutions and 437 rate quotes, covering high-balance money market products that require minimum deposits typically above $100,000. At 1.727%, the jumbo tier slots between high-yield bank MMAs at 3.030% and credit union MMAs at 1.233% — offering a meaningful premium over standard bank products (0.738%) but well below what the most competitive online institutions offer to all depositors. Week-over-week trend data for this tier will begin with the April 27 release.

High-yield bank MMAs (APY ≥ 2.50%) edged down just 0.003 points to 3.030% across 299 institutions and 1,716 rate quotes — effectively flat and maintaining the tier’s substantial premium over the rest of the market. Standard bank MMAs (APY < 2.50%) ticked up 0.008 points to 0.738% across 886 institutions — a modest counter-trend move in the broadest tier. The high-yield-to-standard spread narrowed fractionally to 2.292 percentage points, down from 2.303 last week, but remains the defining characteristic of today’s MMA landscape.

Credit union money market gained 0.016 points to 1.233% across 1,381 credit unions and 199 verified rate quotes — the largest weekly move among the comparable tiers and a continuation of the modest upward drift seen in credit union deposit products over recent weeks. Business money market added 0.013 points to 1.097% across 212 institutions and 1,226 rate quotes, its second consecutive weekly gain. The concurrent gains in both credit union and business tiers, while high-yield held flat, suggest that mid-market institutions are still gradually adjusting rates upward even as the top of the market consolidates.

The broad gains across standard, credit union, and business MMA tiers this week — while high-yield held nearly flat — reflect a market in which mid-tier institutions are still gradually adjusting rates in response to the competitive environment established by online banks over the past year. This is a typical lagging pattern: the high-yield tier reprices quickly in response to funding cost signals, while credit unions and community banks make smaller, less frequent adjustments that trail the leading edge by weeks or months. The fact that three tiers gained simultaneously while the top tier held flat suggests the broader market is still normalizing toward the competitive rate level rather than following the top tier lower.

The debut of the Jumbo MMA tier at 1.727% fills an important gap in the coverage picture. High-balance depositors — those with $100,000 or more in liquid savings — have historically received premium pricing in exchange for their deposit size, but the jumbo tier’s 1.727% average is substantially below the 3.030% high-yield average available to any depositor. This suggests that, in the current rate environment, maintaining a large balance at a traditional jumbo-tier institution does not compensate for what a competitive high-yield MMA would provide.
