A bilateral loan is a direct lending arrangement between one borrower and one lender, with no other financial institutions involved. It is the most basic form of corporate credit, typically ranging from roughly $10 million to $200 million, and it remains the standard choice for middle-market companies that need capital without the complexity of coordinating multiple banks. Because the single lender holds all the risk and makes all the decisions, bilateral loans close faster and stay more private than their multi-lender counterparts.
How a Bilateral Loan Works
The mechanics are straightforward. A company approaches a bank, or the bank approaches the company, and the two parties negotiate a loan agreement directly. The lender commits the full amount, disburses the funds, monitors the borrower’s financial health, and collects repayment. No agent bank sits in between, no syndicate members need updates, and no inter-creditor agreement governs who gets paid first. Everything runs through a single relationship.
Bilateral facilities fund a range of corporate needs. Revolving credit lines cover day-to-day working capital swings, letting the borrower draw and repay as cash flow demands. Term loans finance equipment purchases, acquisitions, or other capital investments on a fixed repayment schedule. Some borrowers maintain both a revolver and a term loan with the same bank under a single credit agreement.
The lender’s credit team conducts its own due diligence, reviewing audited financial statements, tax returns, cash flow projections, and whatever else it needs to underwrite the risk. Because only one institution is doing this work, the process moves faster and the borrower shares sensitive data with fewer people. A typical bilateral closing can wrap up within four to six weeks of the initial term sheet.
Bilateral vs. Syndicated Loans
The core difference is the number of lenders, and everything else follows from that. A syndicated loan pools capital from a group of banks, led by an arranging agent that coordinates documentation, disbursements, and ongoing communication for the whole group. In a bilateral deal, the single lender handles all of that internally.
Risk distribution works differently too. The bilateral lender absorbs 100% of the default exposure. If the borrower can’t pay, that one bank takes the entire loss. Syndicated lenders divide the exposure among themselves, with each participant holding a slice of the total commitment. This risk-sharing is the primary reason syndicated structures exist for very large transactions.
Confidentiality is another meaningful distinction. A syndicated deal requires sharing the borrower’s financials with every participating bank and sometimes with potential secondary-market buyers of the debt. Companies with proprietary business models or competitive sensitivities often choose bilateral lending specifically to avoid that kind of information leak. Only one institution sees the numbers.
Speed follows from simplicity. Syndicated loans require inter-creditor agreements, allocation negotiations among the bank group, and often separate legal reviews by each participant’s counsel. Bilateral deals skip all of that. Syndicated transactions routinely take two to three months or longer.
Pricing and Interest Rates
Most bilateral corporate loans carry a floating interest rate tied to a benchmark. Since the transition away from LIBOR, virtually all new dollar-denominated loan agreements use the Secured Overnight Financing Rate, known as SOFR, as their reference rate. SOFR measures the cost of borrowing cash overnight using Treasury securities as collateral, and the Federal Reserve Bank of New York publishes it each business day.1FEDERAL RESERVE BANK of NEW YORK.

In practice, most loan agreements reference Term SOFR, a forward-looking rate published in one-month, three-month, six-month, and twelve-month tenors, because it behaves operationally like the old LIBOR rates borrowers and lenders were accustomed to. The borrower’s all-in rate equals the Term SOFR rate for the chosen interest period plus a credit spread, often called the margin, that reflects the borrower’s risk profile. Spreads on middle-market bilateral loans commonly fall between 150 and 300 basis points (1.50% to 3.00%), with investment-grade borrowers at the low end and leveraged credits at the high end.
The borrower also pays an origination fee at closing and ongoing commitment fees on undrawn amounts of a revolver. Overall fees run lighter than on a syndicated deal because there’s no syndication infrastructure to fund.
Covenants, Collateral, and Guaranties
The credit agreement governs the borrower’s obligations throughout the life of the loan, and covenants are where the lender protects its investment.
Affirmative covenants are things the borrower must do: deliver quarterly and annual financial statements on schedule, maintain insurance, pay taxes, and preserve the collateral. A typical agreement requires unaudited quarterly financials within 45 days of quarter-end and audited annual statements within 90 to 120 days of fiscal year-end.
Negative covenants are things the borrower cannot do without the lender’s written consent. Common restrictions include taking on additional debt above a specified threshold, selling major assets, making acquisitions, paying dividends beyond a set amount, or changing the company’s line of business.
Most bilateral agreements also include two or three financial maintenance covenants tested quarterly. The debt service coverage ratio is one of the most common, typically requiring the borrower to maintain a ratio of at least 1.20x, meaning cash flow must cover debt payments by a margin of at least 20%. A leverage ratio (total debt divided by EBITDA) and a minimum liquidity or current ratio often round out the package.
Collateral
Bilateral term loans and many revolving facilities are secured. A blanket security interest in all of the borrower’s personal property is common, covering equipment, inventory, receivables, and general intangibles. The lender perfects this interest by filing a UCC-1 financing statement with the appropriate state office, which puts other creditors on notice and establishes the lender’s priority position. Filing fees for UCC-1 statements vary by state, generally between $10 and $100 depending on the filing method. If real property secures the loan, a mortgage or deed of trust gets recorded as well.
Guaranties
Lenders frequently require guaranties to backstop the borrower’s obligations. For a subsidiary borrower, the parent company typically provides a corporate guaranty. For privately held companies, banks routinely expect the principal owners to sign personal guaranties, particularly when the business lacks a long operating history or substantial unencumbered assets. A personal guaranty pierces the limited liability that the business entity would otherwise provide, giving the lender a direct claim against the owner’s personal assets if the company defaults.
Prepayment
Revolving credit lines typically allow repayment and re-borrowing without penalty. Term loans are different. Because the lender priced the loan expecting a certain stream of interest income over its full term, early repayment can cost the borrower a penalty. The most common structures are make-whole provisions, which compensate the lender for the present value of lost interest payments, and step-down schedules, where the penalty starts at 1% to 2% of the prepaid amount and decreases to zero over the first few years. When interest rates have dropped since origination, make-whole penalties can be substantial because the lender can’t reinvest at the original rate.
Why Borrowers Choose Bilateral Loans, and Where They Fall Short
The biggest practical advantage is relationship depth. When one bank makes the entire lending decision, the borrower deals with a single credit officer who knows the business. Covenant waivers, amendment requests, and draw-down approvals don’t require polling a group of lenders with competing interests. If the company hits a rough quarter and needs flexibility, it negotiates with one decision-maker rather than assembling a supermajority vote from a syndicate.
Lower upfront costs matter too. Syndicated loans carry arrangement fees, agent fees, and sometimes participation fees paid to each bank in the group. Bilateral deals strip those layers out.
Closing speed is worth emphasizing because in corporate finance, timing often determines whether a deal happens at all. A company trying to close an acquisition or lock in equipment pricing before it changes needs capital on a predictable timeline.
The same simplicity creates real vulnerabilities. Concentration risk is the most obvious: the borrower’s entire credit facility depends on one institution’s willingness to lend. If that bank tightens its credit standards, gets acquired, exits the market, or decides the borrower’s industry is too risky, the company loses its entire funding source in one stroke.
Refinancing risk compounds this problem at maturity. When a bilateral term loan or revolver comes up for renewal, the borrower has no existing lender group to fall back on. If the single lender declines to renew, the company must find a replacement bank from scratch, often under time pressure. The Office of the Comptroller of the Currency has flagged refinance risk as a systemic concern, noting that when borrowers cannot replace existing debt under reasonable terms, the result can be underperforming or nonperforming loans.
Borrowing capacity is inherently limited. A single bank can only extend so much credit to one borrower before hitting its own internal concentration limits and regulatory lending caps. Companies that need more than roughly $150 million to $200 million in committed facilities will almost certainly outgrow the bilateral structure and need to syndicate.
Having only one lender can also reduce competitive tension on pricing. When multiple banks compete to participate in a syndicated deal, the borrower benefits from market discipline. In a bilateral negotiation, the lender faces no direct competition, which can translate to wider spreads or stricter terms.
What Happens If the Borrower Defaults
A covenant violation or missed payment constitutes an event of default under the credit agreement. Most agreements distinguish between payment defaults, which often carry a short cure period of five to ten business days, and covenant defaults, which may allow 15 to 30 days to remedy the breach. If a financial covenant is missed, the borrower typically has 30 days from receiving written notice to either cure the default or negotiate a resolution.
This is where the bilateral structure cuts both ways. Negotiating with a single lender is far simpler than persuading a syndicate. The bank can agree to a waiver, reset the covenant levels, or restructure the loan terms without polling other participants. If that one lender decides to accelerate the loan and demand immediate full repayment, however, the borrower has no other members of a lending group to lobby for a different outcome.
Before reaching acceleration, most lenders prefer a workout. The lender may offer a forbearance agreement, temporarily holding off on enforcement while the borrower implements corrective steps. In exchange, the lender often extracts concessions: additional collateral, tighter reporting requirements, higher pricing, or the addition of a new guarantor. If the workout fails, the lender’s remedies include accelerating the loan balance, seizing collateral, and pursuing guarantors. For secured loans, this means the lender can foreclose on pledged assets or exercise its rights under the security agreement to liquidate inventory, collect receivables, and take possession of equipment.
Tax Treatment of Interest
Interest paid on a bilateral loan is generally deductible as a business expense, but federal tax law caps how much interest a company can deduct in any given year. Under Section 163(j) of the Internal Revenue Code, a business can deduct interest expense only up to the sum of its business interest income plus 30% of its adjusted taxable income for the year.2Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Any disallowed interest carries forward to future tax years.
Small businesses are exempt. If a company’s average annual gross receipts over the prior three years fall at or below the inflation-adjusted threshold (set at $31 million for 2025, with the 2026 figure expected to be modestly higher), the interest deduction cap does not apply.2Internal Revenue Service.

Starting in tax years beginning after December 31, 2025, the calculation of adjusted taxable income changes.
