Not every investor qualifies for a securities-based line of credit. Here is the minimum portfolio size you need at each major lender.
The minimum portfolio size to qualify for an SBLOC in 2026 ranges from $100,000 (Schwab, Wells Fargo, Merrill, Fidelity) to $2,000,000 (BNY Mellon Wealth). Most self-directed retail investors with $100K+ in a taxable brokerage account qualify at Schwab Pledged Asset Line or Wells Fargo Priority Credit Line. Wirehouse and private bank tiers (Morgan Stanley $250K, UBS $250K, JPMorgan $500K, Goldman $1M) offer tighter spreads but require relationship access. Retirement accounts (IRAs, 401(k)s) cannot be pledged. Eligible collateral is taxable brokerage holdings only.
Most major brokerages set their SBLOC minimum at $100,000 in eligible securities. This includes Fidelity, Charles Schwab and E*TRADE. Below that threshold, the administrative cost doesn't justify the lender's effort.
Morgan Stanley and Goldman Sachs require $250,000. Interactive Brokers has no hard minimum but economics become unfavorable below $50,000. For the full list, see our 2026 SBLOC requirements guide.
Each major US lender sets its own minimum. The differences cluster into three tiers: self-directed retail brokers ($100K accessible), wirehouses ($250K through an advisor), and private banks ($500K+ through a private banker).
| Lender | Minimum Portfolio | Spread (May 2026) | Access Path |
|---|---|---|---|
| Schwab PAL | $100,000 | SOFR + 1.55% to 3.65% | Online, self-directed |
| Wells Fargo PCL | $100,000 | SOFR + 1.50% to 3.50% | Via Wells Fargo Advisors |
| Merrill LMA | $100,000 | SOFR + 1.65% to 3.70% | Via Merrill advisor |
| Fidelity Margin | No formal minimum | Tiered base rate (11.83% under $25K to 4.83% over $1M) | Online margin agreement |
| Morgan Stanley LAL | $250,000 | SOFR + 1.50% to 3.00% | Via MS advisor |
| UBS Credit Line | $250,000 | SOFR + 1.40% to 3.30% | Via UBS advisor |
| JPMorgan Premier | $500,000 | SOFR + 1.70% to 3.85% | Via private banker |
| Goldman GS Select | $1,000,000 effective | SOFR + 1.30% to 3.00% | Via Goldman private wealth |
| BNY Mellon Wealth | $2,000,000 | SOFR + 1.35% to 2.95% | Via private banker |
Notice the inverse relationship: higher minimums unlock tighter spreads. A borrower with $250K at Morgan Stanley pays roughly 100 to 150 basis points less than the same borrower at Schwab in equivalent balance tiers. The friction is the advisor relationship requirement. For self-directed investors who do not want an advisor, Schwab and Wells Fargo are the practical defaults.

Eligible:
NOT eligible:
A portfolio showing $500,000 may contain only $300,000 in eligible collateral once you exclude retirement holdings, crypto and micro-cap positions.
A $100,000 Treasury portfolio can support $85,000-$95,000 in borrowing, while $100,000 in mid-cap stocks might only yield $40,000-$60,000.
If a single stock exceeds 25-30% of your pledged portfolio, most lenders apply a concentration penalty. A $400,000 diversified ETF portfolio plus $200,000 in one tech stock might get 70% on the ETFs but only 35-40% on the concentrated position.
Some lenders cap eligible value of any single position at 50% of total portfolio regardless of actual weight.
Worked example with a $300,000 portfolio:
Total borrowing power: approximately $210,000 (70% blended advance rate).
Key takeaway: Your borrowing power depends on what you own, not just how much. A $200,000 Treasury portfolio can yield more borrowing capacity than a $300,000 portfolio concentrated in volatile stocks.
Market declines can trigger a maintenance call. The process: Day 1. Portfolio drops below required ratio. Day 2-3. Maintenance notice. Day 5-7. Forced liquidation if no response.
Safest approach: borrow no more than 30-40% of eligible collateral value. For more on broker-specific policies, see our broker comparison.
Replace individual stocks with broad-market ETFs (50-65% advance rate becomes 65-75%). Add 20-30% in Treasuries or investment-grade bonds to push blended advance rate above 75%. Keep concentrated positions in a separate, unpledged account.

The minimum is the floor for opening a line. The practical borrowing power depends on portfolio composition. Three concrete scenarios:
Below all major SBLOC minimums. Options: keep building the portfolio to $100K, or use a Fidelity margin account (no minimum but tiered pricing makes the under-$25K balance prohibitively expensive at 11.83%). For most borrowers under $100K, traditional unsecured credit (personal loan, business LOC, credit card balance transfer) is the practical alternative until the portfolio grows.
Mix: 70% diversified equity ETFs ($175K), 30% investment-grade bonds ($75K).
This is the typical mid-tier retail borrower profile. Borrowing 50% of capacity ($91K) keeps the cushion against a normal market correction.
Mix: 60% diversified equity ($900K), 25% investment-grade bonds ($375K), 15% U.S. Treasuries ($225K).
The same borrower at Schwab PAL at $500K utilization would pay approximately 7.05% = $35,250. The Morgan Stanley relationship saves roughly $6,250 per year on a $500K balance, justifying the advisor friction.
Three practical paths if you do not yet meet a $100K minimum.
The simplest answer for most borrowers. Continue contributing to a taxable brokerage account until you cross the $100K threshold. The compounding cost of waiting is typically small (a few months to 2 years of foregone SBLOC access), and the financial discipline of building the portfolio is generally more valuable than the credit access.
If you have $40K at Schwab, $30K at Vanguard, and $25K at Fidelity, no single broker hits the threshold. Consolidating into one broker (typically Schwab or Wells Fargo for the cheapest minimum tier) unlocks SBLOC eligibility immediately. Asset transfers (ACATS) take 5 to 10 business days and are free at most receiving brokers.
Fidelity Margin has no minimum. The under-$25K tier prices at 11.83% (vs. typical SBLOC at 7%), which is roughly 4.5 percentage points more expensive. For short-term bridge needs (under 90 days), the higher rate may still be acceptable. For permanent borrowings, the rate differential argues for waiting until you can open a real SBLOC.
Borrowers often assume their total investable wealth (including IRA, 401(k), 529) counts toward the SBLOC minimum. It does not. Internal Revenue Code rules prohibit pledging retirement assets as collateral for personal loans. The minimum applies to taxable brokerage account holdings only.
A $100K portfolio borrowing $70K (the full capacity at 70% advance rate on equity) leaves zero cushion. A 20% market drop pushes the maintenance call. The safer discipline is borrowing no more than 40 to 50% of capacity, even at small portfolio sizes where the dollar amounts feel modest.
If a $200K portfolio is 60% in one stock, most lenders cap the borrowing value of that single position at 25% to 50% of total collateral. The effective advance rate falls materially below the 70% headline number. Diversification before pledging matters more than total portfolio size.
Margin accounts at retail brokers have no portfolio minimum and use Reg T initial-equity rules (50% on equity purchases). A pure SBLOC operates under Reg U non-purpose rules with broker-set portfolio minimums (typically 00K+). The two products look similar but the eligibility logic, the maintenance bands, and the IRS treatment of interest differ materially. A borrower who satisfies margin requirements does not automatically qualify for a dedicated SBLOC, and vice versa. Confirm which product the lender is offering before signing.
Goldman Sachs GS Select states a $75,000 minimum on its product page, the lowest published among major US lenders. For practical purposes, Schwab PAL and Wells Fargo PCL at $100,000 are the most accessible. Below that, Fidelity Margin (no formal minimum) is the only option but pricing is materially worse at small balances.
Just the pledged account. You can hold $500K across multiple accounts at the same broker but only pledge $100K from one account; the SBLOC borrowing capacity is calculated from the pledged account alone. The benefit of total relationship size only kicks in at wirehouses where overall AUM influences rate tier.
Yes. Joint taxable accounts (joint tenants, tenants in common, community property) qualify. Both account holders are jointly and severally liable for the loan balance. Most lenders accept this structure without additional documentation.
Yes for revocable trusts and irrevocable trusts, with documentation. The trust must demonstrate authority to pledge under the trust agreement. Some lenders require a written legal opinion from the trustee's counsel before approving.
No. The minimum is a portfolio-opening threshold. As long as your pledged portfolio stays above the broker's maintenance requirement (typically 30 to 40% equity ratio), you remain in good standing regardless of your initial entry size.
Most lenders do not close existing lines based on the portfolio falling below the original minimum. The risk trigger is the maintenance equity ratio, not the absolute portfolio size. A line opened at $150K can survive a drawdown to $80K as long as the borrower's outstanding draw remains within the maintenance band.
