The official national average interest rate on savings accounts is stuck at 0.38 percent, according to recent federal data, even as online banks continue to advertise yields above 4 percent. That gap hits everyday savers who keep money in traditional brick-and-mortar accounts while inflation and market rates remain elevated. It also raises questions about why most banks tied to branches are still paying so little on deposits.
Why online savings outpace branch accounts now
The Federal Deposit Insurance Corporation lists the national deposit rate for Savings at 0.38 percent in its April 2026 benchmark, and the same 0.38 percent figure again in the May 2026 release, both calculated as weighted averages across insured institutions that offer savings products and accept deposits from the public, according to the FDIC methodology. Because that benchmark barely moves between consecutive releases, it signals that the bulk of banks, many of them branch based, continue to cluster near that low rate even as some online accounts advertise returns above 4 percent that sit well outside the average.
The FDIC’s April 2026 national rates and rate caps update, issued under a Revised Rule on April 20, 2026, shows how regulators frame the ceiling on what most banks are expected to pay. For non-maturity deposits such as standard savings, the national rate cap is defined as the national rate plus 75 basis points, or as an alternative tied to Treasury yields, and for non-maturity products the cap also references the federal funds rate plus 75 basis points, according to the agency’s benchmark framework in the FDIC national rates table. That structure keeps the formal cap well under 1 percent for many savings accounts even while policy and market rates remain higher, which helps explain why most branch-based offers have not climbed anywhere near the 4 percent level.
The working hypothesis for many rate watchers is that high fixed costs tied to branches and legacy systems make banks slower to pass higher yields through to savers, and the FDIC data is consistent with that view. If policy rates and Treasury yields, which feed into the cap through the federal funds rate plus 75 basis points and the Treasury-yield-based alternative, have risen significantly while the national savings benchmark sits at 0.38 percent in back-to-back releases, then something other than the rate environment alone is holding down payouts. Branch-heavy institutions that rely on customer inertia and physical convenience may feel less pressure to raise rates, while leaner online banks can afford to compete aggressively for deposits.
The evidence behind the 0.38 percent benchmark
The FDIC’s May 2026 national rates and rate caps posting is the clearest snapshot of how little most savers earn on traditional accounts. In that document, the Primary benchmark for Savings again lists a national deposit rate of 0.38 percent, based on a methodology that weights rates by deposit volume at insured depositories, according to the FDIC Savings benchmark. Because the same 0.38 percent figure appears in the April and May tables, it suggests that even as individual banks tweak promotions, the overall average has barely budged.
Historical context comes from the FDIC’s index of previous national rate releases, which links to Revised Rule Excel files that track the Savings benchmark over time. On that page, the agency lists earlier monthly updates, including the April 20, 2026 and May 18, 2026 postings, and the downloadable spreadsheets show the 0.38 percent rate persisting across those months, according to the FDIC previous rates archive. That stability indicates that the national average has been anchored near 0.38 percent even as individual online offers have moved higher.
The cap mechanics tie directly into broader interest rate data. For non-maturity deposits, the cap can be calculated using the federal funds rate plus 75 basis points, and the alternative approach references Treasury yields that are published as constant maturities. Those reference rates appear in the Federal Reserve’s Statistical Release H.15, which provides daily series for the effective federal funds rate and multiple Treasury maturities, according to the Federal Reserve H.15 page. The Treasury yield curve itself, which the FDIC cites in its methodology, is available through the Department of the Treasury’s data pages that list daily yield figures across maturities. These inputs show that policy-linked rates and Treasury yields have been high enough to support far more than 0.38 percent, yet the national cap formula and bank pricing decisions have combined to keep the average low.
What remains unresolved about the rate gap
The available federal data has limits that make it hard to draw firm conclusions about online banks specifically. The FDIC’s national rate tables do not separate online-only institutions from traditional branch-based banks, and the 0.38 percent Savings figure aggregates all insured depositories that meet the benchmark criteria, according to the methodology described in the April and May releases. That means the national average cannot show how much of the gap between 0.38 percent and online offers above 4 percent comes from branch costs, customer behavior, or other factors such as funding needs and competition from money market funds.
Another missing piece is product-level detail. The FDIC benchmarks do not list individual account annual percentage yields, and the Federal Reserve’s H.15 series and Treasury yield data do not link directly to any bank’s pricing choices. As a result, there is insufficient data to determine precisely how many institutions are paying near the 0.38 percent benchmark versus significantly more, or how many depositors have shifted into higher-yield products. The latest publicly available FDIC update through May 2026 confirms that the national Savings rate is 0.38 percent, but it does not reveal how quickly customers are reacting to the gap between branch accounts and online offers.
For savers trying to decide what to do first, the evidence points to a simple starting move: compare the rate on an existing brick-and-mortar savings account with the 0.38 percent national benchmark cited in the FDIC’s April and May tables, then weigh that against the higher yields advertised by online banks that sit outside the FDIC average. The next key development to watch will be whether future FDIC Excel releases show the Savings benchmark rising from 0.38 percent as policy and Treasury rates evolve, which would signal that more institutions are finally sharing higher yields with their depositors.
