High-Yield Money Market Rates Hold at 3.036%; Jumbo Rates Give Back Their Summer Climb

High-yield money market rates were unchanged at 3.036% this week, a higher average than any savings account category or CD term we track, with the Federal Reserve's decision six days away. Jumbo money market rates fell 0.341 points to 1.736% as the small pool of institutions reporting them shrank.

Average money market account rates came through the first full week of September close to where they started it. High-yield money market account rates were exactly unchanged since our September 1 report at 3.036%. Standard money market rates edged up to 0.750%, business money market rates rose 0.011 points to 1.116%, and credit union money market rates held nearly steady at 1.263%. The one large move was down: jumbo money market rates fell 0.341 points to 1.736%, and fewer institutions reported jumbo accounts this week, so some of that drop reflects who is in the average rather than lenders lowering rates.

Outside jumbo accounts, little changed this week

Money market rates by account category, national average APY since mid-April

Average APYs from MonitorBankRates.com's nightly collection, the same series this report's figures come from, updated daily.

High-yield money market rates printed the same average two reports in a row, 3.036%, and no savings account category or CD term we track pays a higher average this week. Standard money market rates rose 0.004 points to 0.750% and business money market rates added 0.011 points to 1.116%, both second gains in the last three reports. Credit union money market rates held nearly steady at 1.263%; that category draws from the smallest pool we track, about 41 institutions, so even its quiet weeks deserve light trust in the third decimal. No category changed places.

Jumbo money market rates fall back to July levels

Jumbo money market rates fell 0.341 points to 1.736%, which undoes, in one report, most of a climb that ran from 1.708% in mid-July to 2.077% at the start of September. The honest reading is less dramatic than the number. Jumbo accounts come from one of the smallest pools we track, and that pool got smaller this week, so part of the drop comes from which institutions reported rather than from lenders lowering what they pay. What a saver with a six-figure balance should take from it: the jumbo average is volatile enough that the quotes you gather yourself matter far more than this line on a chart, and jumbo offers in our data still reach 4.00%.

Money market rates this week: September 1 vs. September 10

If the Fed raises rates Wednesday, these accounts can follow

The Federal Reserve announces its rate decision Wednesday, September 16, and futures markets have treated a quarter-point increase as a close call since late August. The benchmark has held at 3.50% to 3.75% since December, and three committee members voted for an increase in July. For money market savers the mechanics are simple: these rates are variable, so if the Fed raises its benchmark and a bank chooses to pass the increase through, the higher rate lands on accounts savers already hold. The comparison with CDs is worth knowing before Wednesday. For a fifth straight report, high-yield money market accounts pay a higher average than a 12-month CD, 3.036% against the 2.864% in this week's CD report; the edge narrowed from 0.206 to 0.172 points because CD averages rose while money market averages held. A CD locks its rate through whatever the Fed decides, which cuts both ways; a money market account keeps paying more today and stays free to move after Wednesday.

What $25,000 earns in a money market account versus a CD

In dollars, the week's standings look like this: a $25,000 balance at the 3.036% high-yield money market average earns about $759 a year, while the same balance at the 2.864% average from a 12-month CD earns about $716. The money market account earns roughly $43 more and the balance stays reachable all year.

The bottom line for money market savers

Money market averages went into the final stretch before the Fed decision essentially where they stood on September 1, with high-yield accounts at 3.036% still ahead of every CD term and savings category we track. Wednesday's decision can move these accounts without savers lifting a finger, since banks can pass an increase through to existing balances. Savers earning near the 0.750% standard average have the most to gain from comparing offers before then; an account opened this week collects today's higher average and follows whatever comes after September 16.
