NATIONAL — National money market account APYs declined across four of five tracked tiers for the week ending May 04, 2026, with one tier essentially flat. Jumbo MMA posted the week’s largest move, dropping 0.083 points to 1.644% — the most meaningful single-tier move on the page and a notable retracement after the tier’s flat read last week. High-yield MMA slipped 0.038 points to 3.043%, but the tier remains above the 3% mark for a fourth consecutive week. Standard MMA was the lone gainer, edging up just 0.003 points to 0.724%.

High-yield bank MMAs (APY ≥ 2.50%) fell 0.038 points to 3.043%, ending three consecutive weeks of gains in the tier. The pullback partially reverses last week’s +0.051 point gain but leaves the tier well above the 3% threshold. Standard bank MMAs (APY < 2.50%) were essentially flat, edging up 0.003 points to 0.724% — the smallest absolute move on the page. The high-yield-to-standard spread compressed slightly to 2.319 percentage points from last week’s 2.360, but remains historically wide.

Jumbo MMA APYs dropped 0.083 points to 1.644% in the largest tier move this week, reversing last week’s flat read with a meaningful decline. The jumbo tier covers a small universe of high-balance MMA products, and weekly moves of this size are not unusual when a handful of repricing institutions can shift the average. Credit union MMA was nearly flat, easing 0.007 points to 1.242%, ending a two-week winning streak. Business MMA was effectively unchanged at 1.061%, down just 0.003 points — the tier has now stabilized around the 1.06% level after last week’s 0.033-point drop.

The persistent gap between the high-yield tier (3.043%) and the rest of the market remains the defining feature of MMA pricing. At 2.32 percentage points above the standard tier, the spread continues to favor depositors willing to compare options across institution types, though it has compressed modestly each of the past two weeks. With the high-yield MMA now yielding above the corresponding high-yield savings tier (1.973%), the comparison between MMA and savings is relevant for depositors weighing their options — see money market vs. savings account for the structural differences between the two product types. Track how these tier averages evolve through weekly MMA rate movements.

This week’s broadly lower picture in MMA pricing aligns with the directional shift seen across the deposit market more generally — CD rates declined across all eight tracked terms this week, and high-yield savings dropped below 2% for the first time since the late-April rebound. The high-yield MMA tier’s pullback to 3.043% ends a three-week run of gains, but the four-week stretch above 3% is itself a meaningful signal that competitive pressure at the top of the MMA market has not yet rolled over the way it has on the savings side. Online banks and rate-aggressive institutions that drive the high-yield MMA tier appear to be defending higher yields more vigorously than their high-yield savings counterparts.

Jumbo MMA’s 0.083 point decline is worth contextualizing: the tier covers a small universe of high-balance products, so a handful of repricing institutions can shift the weekly average meaningfully. The drop pulls the tier back below 1.65%, returning it to roughly the level it had been at before the prior period’s flat read. Business and credit union MMAs continuing to hold near recent levels suggests the broader deposit pricing changes seen this week are concentrated at the high-yield and jumbo ends of the market, not flowing through to the more stable middle tiers. The high-yield-to-standard spread, while modestly compressed, remains above 2.3 percentage points and continues to make the case for actively shopping rates among institution types.
