Securities-backed lines of credit offer some of the lowest borrowing rates available. Here is what SBLOC interest rates actually look like today.
In May 2026, SBLOC interest rates run roughly 5.80% to 7.95% across major US brokers (SOFR at 4.30% plus a spread of 1.50% to 3.65% depending on balance and lender). Goldman Sachs GS Select offers the tightest spread at +1.30% for $5M+ balances. Schwab and Wells Fargo are most accessible at $100K minimum and price 5.85% to 7.95%. All major SBLOC products are floating-rate and reset monthly with SOFR, so a Fed rate change flows through within 30 to 45 days.
Every securities-backed line of credit starts with a benchmark rate. In 2026, that benchmark is almost always the Secured Overnight Financing Rate (SOFR). Your lender adds a spread on top of SOFR and the sum becomes your all-in borrowing cost.
As of May 2026, SOFR sits at approximately 4.3%. Lender spreads typically range from 1.5% to 3.5%, which means most borrowers pay between 5.8% and 7.8% on their drawn balances. Some ultra-high-net-worth clients with portfolios above $10 million see spreads as low as 0.75%.
Portfolio size is the single biggest driver of your rate. Lenders price risk in tiers.
If your portfolio is close to a tier boundary, transferring additional assets to cross the threshold can save you 0.5% or more.
Each major brokerage prices SBLOCs differently. On a $500,000 portfolio of diversified equities and ETFs in May 2026:
For a deeper breakdown, see our 2026 SBLOC rates by broker comparison.
Most SBLOCs carry variable rates tied to SOFR. When rates were near zero in 2021, borrowers paid under 2%. Today, that same facility costs 6% or more.
A few lenders offer fixed-rate tranches for draws above $250,000, locked for 6 to 24 months. The fixed rate typically adds 0.25% to 0.50% above the variable rate. An insurance premium against further hikes.
Tax treatment matters too. Read our guide to SBLOC tax implications.
Key takeaway: Your SBLOC rate is negotiable. Moving from SOFR + 3.0% to SOFR + 2.0% on a $500,000 draw saves $5,000 per year in interest. Get quotes from at least three brokerages.
Consolidate assets. $300K at Fidelity and $400K at Schwab? Consolidating puts you in the $500K-$1M tier instead of two sub-$500K accounts.
Ask for a rate match. Get a written quote from Interactive Brokers and bring it to your primary broker. Full-service firms routinely match to retain relationships.
Offer additional business. Moving your cash management or advisory relationship to the same firm can reduce your spread by 0.25% to 0.50%.
Time your request. Approach in the final month of a quarter. March, June, September, December. When lending desks are pushing to hit numbers.
Because most SBLOCs are variable-rate, your cost adjusts automatically as SOFR moves. A 0.25% Fed rate cut translates to roughly a 0.25% drop in your SBLOC rate within one reset period.
Monitor your rate monthly. Most lenders will not proactively notify you of changes. If all-in rates cross above 8%, revisit your borrowing strategy. Including a competing firm's SBLOC.
The all-in SBLOC rate you pay is the sum of three components. Understanding each helps you forecast where your rate goes next and identify whether your current pricing is actually competitive.
The Secured Overnight Financing Rate (SOFR) replaced LIBOR as the dominant US benchmark in 2022 to 2023. SOFR is published daily by the Federal Reserve Bank of New York and represents the rate at which institutional borrowers fund themselves overnight in the Treasury repo market. Major lenders use the 1-Month CME Term SOFR (currently 4.30% in May 2026) as the index for SBLOC pricing.
SOFR moves with Federal Reserve policy. A 25 basis point Fed rate change typically moves SOFR by 22 to 25 basis points within 1 to 2 weeks. Your SBLOC rate adjusts at the next monthly reset, typically 30 to 45 days after a Fed action.
On top of SOFR, the lender adds a contractual spread that covers their cost of capital, credit risk, operational expense, and profit margin. The spread ranges from 1.30% (Goldman GS Select at the top tier) to 3.85% (JPMorgan Premier Line at lower balance tiers).
The spread is the only component you can negotiate or influence. SOFR is exogenous. Tier discounts are formulaic. Spread is set by underwriting and is the lever for any rate-saving conversation with your lender.
Most lenders publish a tiered spread schedule where larger balances get tighter spreads. The mechanics vary:
For any borrower at the boundary of two tiers, moving an additional $100K to $250K of assets across the threshold can save 25 to 75 basis points of spread.
The same SBLOC rate quote produces very different annualized costs depending on portfolio size, draw level, and lender choice. Three concrete examples illustrate how the math actually works in May 2026.
At this utilization level, the borrower should not have taken the line. The math works on paper but the maintenance call risk dominates.
This is a typical mid-tier borrower with appropriate utilization discipline. The relationship pricing saves roughly 75 basis points vs Schwab rack rate, worth $2,250 per year.
This is the rate environment private wealth clients see. The 2.15 percentage point gap vs Profile A ($21,500 of difference on $1M of identical draw) is the price the small borrower pays for not being in a relationship pricing tier.
Understanding where rates came from helps calibrate expectations for where they go next. SBLOC rates moved through three distinct regimes over the past six years.
| Year | SOFR Avg | Typical SBLOC Rate Range | Defining Event |
|---|---|---|---|
| 2020 | 0.10% | 2.50% to 4.25% | COVID emergency cuts, Fed Funds at zero |
| 2021 | 0.05% | 2.50% to 4.25% | Rates held near zero all year |
| 2022 | 2.20% | 3.50% to 8.50% | Fed hiked 425 bps from March to December |
| 2023 | 5.05% | 7.00% to 10.00% | SOFR peaked above 5.4% in mid-year |
| 2024 | 5.10% | 6.50% to 9.50% | Fed paused, first cuts late in the year |
| 2025 | 4.60% | 5.95% to 8.50% | Gradual cuts brought SOFR below 5% |
| 2026 (current) | 4.30% | 5.80% to 7.95% | Fed in data-dependent pause |
The 2022 hiking cycle was the formative event for this market. Borrowers who took out SBLOCs in 2020 at 3% to 4% rates watched their cost more than double over 18 months. Forward-looking borrowers should treat any current SBLOC borrowing as exposed to a similar shock if inflation re-accelerates and the Fed resumes hiking.
Because SBLOC rates float, every borrower with an outstanding balance carries duration risk. The mechanics are mechanical but the magnitudes can be surprising for borrowers who treat the rate as quasi-fixed.
For lenders using 1-month CME Term SOFR (Schwab, Wells Fargo, Merrill, Fidelity, Morgan Stanley): your rate resets on or about the first business day of each month based on the previous month's SOFR. A Fed action on March 15 affects April's reset based on March's SOFR average.
For lenders using compound-average SOFR (some private banks, certain wirehouse products): the reset is slower, averaging SOFR over a 1-month or 3-month lookback. This dampens volatility but delays both rate increases and rate decreases.
On a $300,000 SBLOC draw, a 100 basis point rate increase translates to $3,000 per year of additional interest expense. Over a 3-year holding period, that compounds to $9,000 of additional cost. Over a 5-year period, $15,000. Compared to a fixed-rate alternative (mortgage refi, term loan), the cumulative duration cost of floating-rate exposure can dwarf the upfront rate savings.
The same triggers in reverse work for rate cuts: a 100 bp rate drop is a window to maintain the borrowing if it remains useful, or to draw more if appropriate.
SBLOC borrowers benefit from understanding what rate path the futures market is currently pricing, because that path is the consensus forecast for your future borrowing cost.
As of May 2026, the Fed Funds futures market is pricing roughly 50 to 75 basis points of additional Fed cuts through end of 2026, which would bring SOFR to approximately 3.60% to 3.80% by year-end. Translating to SBLOC rates, mid-tier borrowers (Schwab PAL at the $250K to $500K tier) would see all-in rates compress to approximately 6.50% to 6.80% by December 2026 if the futures path proves correct.
That forecast carries meaningful tail risk in both directions:
For borrowers with multi-year time horizons, the rate forecast matters more than the spot rate. A floating-rate SBLOC effectively imports the entire forward curve into your borrowing cost. If you are confident rates will fall meaningfully, the floating-rate exposure helps you. If you suspect they will rise or stay flat, a fixed-rate alternative may be safer.
SBLOC rates are best understood in the context of the full menu of borrowing options available to a US household or business in 2026. Decisions about whether to use an SBLOC at all depend on what the next-best alternative actually costs.
| Borrowing Option | Typical Rate (May 2026) | Tax Deductible? | Collateral |
|---|---|---|---|
| SBLOC (mid-tier) | 6.50% to 7.50% | If investment or business use | Securities |
| SBLOC (private wealth tier) | 5.60% to 6.30% | If investment or business use | Securities |
| 30-year fixed mortgage | 6.50% to 7.25% | Yes, if for home purchase | Home |
| HELOC | 8.50% to 10.50% | Only if for home improvement | Home equity |
| Auto loan (60-month) | 7.00% to 9.50% | No (personal use) | Vehicle |
| SBA 7(a) small business loan | 9.50% to 11.50% | Yes (business interest) | Business assets + personal guarantee |
| Unsecured personal loan | 10.00% to 18.00% | No | None |
| Business credit line (unsecured) | 11.00% to 16.00% | Yes (business interest) | None (sometimes personal guarantee) |
| Credit card APR | 20.00% to 25.00% | No | None |
Three observations from the comparison shape most SBLOC use decisions:
SBLOC sits between mortgage and HELOC on rate. For home-purchase use, a 30-year fixed mortgage is competitive on rate and superior on tax treatment (interest is generally deductible) and risk profile (no maintenance call risk). SBLOC wins on speed and flexibility but loses on rate parity.
SBLOC dominates all unsecured options. Credit cards (20% to 25%), unsecured personal loans (10% to 18%), and unsecured business credit lines (11% to 16%) all cost 200 to 1,800 basis points more than SBLOC at the mid-tier. For any borrower with sufficient pledgeable assets carrying unsecured high-rate debt, replacing it with SBLOC funding is one of the highest-ROI financial moves available.
SBLOC is cheaper than SBA for business use. SBA 7(a) loans at 9.5% to 11.5% cost roughly 250 to 400 basis points more than SBLOC at the mid-tier. The trade-off is that SBA loans typically have longer amortization, fixed-rate options, and avoid putting a personal portfolio at maintenance-call risk. For working capital needs under $500K, SBLOC often wins on cost. For long-term capital needs that justify rate certainty, SBA wins on structure.
The headline rate understates the true differential because tax treatment varies materially. For a borrower in the 32% marginal bracket using funds for investment purposes (where SBLOC interest qualifies as investment interest expense on Form 4952), the after-tax cost works out to:
The deductibility-driven gap means an SBLOC used for qualifying investment can cost less than half what an apparently cheaper alternative actually costs in personal-use form. Always model after-tax, not headline.
The tightest published spread is Goldman Sachs GS Select at SOFR + 1.30% for $5M+ balances, producing an all-in rate of approximately 5.60% in May 2026. Below that, ultra-high-net-worth clients at certain private banks may negotiate spreads as tight as SOFR + 1.00% in specific large-relationship contexts.
Not at major retail brokers. All Schwab PAL, Wells Fargo PCL, Merrill LMA, Morgan Stanley LAL, Fidelity Margin, and similar products are 100% floating with monthly resets. A few private bank facilities offer optional fixed-rate term advances against securities (typically 1 to 5 year fixed), but pricing is materially worse than the floating alternative.
Dramatically lower. Credit card APRs average 20% to 25% in 2026. Personal loan rates run 10% to 18% for typical borrowers. SBLOC rates at 5.80% to 7.95% are roughly one-quarter to one-third the cost of unsecured consumer debt. For borrowers with sufficient pledgeable assets, replacing unsecured debt with SBLOC funding can save thousands per year in interest expense.
Markets currently price modest Fed easing through end of 2026, which would bring SBLOC rates down 50 to 75 basis points from current levels. The forecast carries material uncertainty in both directions. If inflation re-accelerates, rates could stay flat or rise. If the economy slows sharply, rates could fall faster than the consensus path.
The all-in rate captures interest only. Most major SBLOC providers have no origination fee, no annual fee, and no draw fee. Some private bank facilities charge annual maintenance fees of $250 to $1,000. Wire transfer fees of $25 to $35 apply per draw at most lenders. Confirm full fee structure before signing.
Most lenders reset monthly on the first business day of each month using the previous month's SOFR average. A Fed action affects your rate at the next monthly reset, typically 30 to 45 days later. Some lenders use 3-month or compound-average SOFR which lags somewhat further.
The rate quoted on a lender's website is the starting point, not the final number. Ask these five questions of any prospective SBLOC lender before signing. The answers reveal whether the headline rate is actually the rate you will pay.
Acceptable answers: 1-month CME Term SOFR with monthly reset (standard at Schwab, Wells Fargo, Merrill, Morgan Stanley). Alternative answer: 3-month or compound-average SOFR (some private banks, slower reset). The reset frequency determines how quickly Fed actions affect your cost. Any answer involving LIBOR is a red flag in 2026 (LIBOR is decommissioned).
The lender should provide a written spread quote tied to a specific balance tier. Get the tier definition in writing: is it based on outstanding draw, pledged assets, or total relationship balance? Different lenders use different definitions and the same nominal balance can fall in different tiers across institutions.
The contract typically grants the lender broad discretion. Ask for the specific maintenance equity ratio (typically 30% to 40% for diversified portfolios). Ask for the standard cure window (typically 1 to 5 business days at retail brokers, sometimes longer at private banks). Get any deviation from standard in writing.
Most major SBLOCs have no origination fee, no annual fee, no draw fee. Confirm. Also ask about wire transfer fees per draw ($25 to $35 typical), forced-sale processing fees ($100 to $500 at some lenders during a margin call liquidation), and any minimum borrowing requirements that would create de facto fees on small or sporadic draws.
This question signals you are shopping. At advisor-led firms (Wells Fargo, Morgan Stanley, JPMorgan, Merrill, UBS), the answer is often yes, and the lender will provide a competitive counter-quote within 1 to 3 business days. At fully self-directed brokers (Schwab, Fidelity), the answer is typically no because pricing is system-driven. Knowing which category your lender falls into before you ask sets the right expectation.
The borrowers who pay the lowest SBLOC rates do not necessarily pick the cheapest headline lender. They pick a lender that will negotiate, then they negotiate competently using competing quotes and relationship leverage. The five questions above are the tactical infrastructure for that negotiation.
