Most people assume that borrowing money means temporarily giving something up, but IUL loans break that assumption entirely. When you take a loan against the cash value of your indexed universal life insurance policy, the money you receive comes from the insurer’s general reserve account, and your cash value stays exactly where it is inside the policy, continuing to earn index-linked interest credits. When those credits exceed the rate you are being charged on the loan, the net difference works in your favor. That spread is called positive arbitrage, and it is what separates IUL loans from virtually every other form of consumer or business borrowing.

What Is an IUL Loan and How Does It Work?
IUL loans are policy loan issued by your life insurance carrier against the accumulated cash value inside your indexed universal life insurance policy. When you request an IUL loan, the insurer does not deduct money from your cash value account, instead, the carrier advances funds from its own general account and places a collateral lien on your cash value balance. Your policy account continues to operate as if the money had not moved, which means it remains in the indexed strategy and can continue earning interest credits tied to a benchmark index, such as the S&P 500.
This is the structural distinction that sets IUL loans apart from nearly every other borrowing vehicle available to individuals. A home equity line of credit reduces the equity you have built in your property when you draw from it. A 401(k) loan removes the borrowed amount from your retirement account, reducing the balance that would otherwise be compounding on your behalf. With IUL loans, the underlying asset continues working throughout the entire period the loan is outstanding, which is why the concept of positive arbitrage is even possible.
Under IRC Section 7702, life insurance policies must satisfy specific definitional requirements to maintain their tax-advantaged status. When those requirements are met and the policy remains in force, an IUL loan is not classified as taxable income by the IRS. That tax treatment is one of the primary reasons IUL loans have become a strategic consideration for high-income professionals and business owners who need access to capital without generating a reportable income event.
Understanding Positive Arbitrage in IUL Loans
Positive arbitrage in the context of IUL loans is the net gain that occurs when your cash value collateral earns a higher index-crediting rate than the loan interest rate charged by the carrier. If your policy credits 7% to your indexed account in a given policy year while you are paying 5% on your outstanding IUL loan, the 2% positive spread means your collateral is generating more than the loan costs you. Your money is, in a real and measurable sense, growing even while deployed as borrowed capital.
There is an important clarification that honest financial guidance requires here. Positive arbitrage is a structural feature of participating IUL loans, and it is a genuine, documented mechanism, but it is not a guaranteed outcome. The index crediting rate changes from year to year based on how the selected benchmark index performs, and the floor and cap provisions set by your carrier determine the range of possible credits.
The National Association of Insurance Commissioners (NAIC), through Actuarial Guideline 49, limits how much positive arbitrage carriers are permitted to illustrate in policy projections, specifically to prevent sales materials from overstating the benefit. The regulation controls the maximum illustrated spread between the crediting rate and the loan interest rate to ensure that projected outcomes remain realistic.
What this means practically is that positive arbitrage is a conditionally achievable outcome on IUL loans, not a guarantee, and the conditions that produce it are tied to both market performance and the type of loan structure your policy uses.
Participating vs. Non-Participating IUL Loans: The Difference That Determines Everything
The loan structure you select when borrowing from your policy determines whether positive arbitrage is even possible. Two primary IUL loan types exist across most carrier platforms, and the difference between them is the single most consequential decision a policyholder can make when accessing cash value through IUL loans.
Participating IUL Loans (Indexed Loans)
A participating IUL loan, often called an indexed loan or variable loan depending on the carrier, keeps your cash value collateral inside the indexed crediting strategy after the loan is issued. The portion of your cash value that serves as collateral for the loan continues to earn interest credits tied to the performance of the selected market index, subject to the same cap and floor structure that governs the rest of your policy. Because the collateral remains actively indexed, it retains the potential to earn above the loan interest rate, which is the specific condition required for positive arbitrage to occur on your IUL loan.
Carriers such as National Life Group have documented that their participating loan options, including the Participating Variable Loan and the Participating Declared Loan introduced in 2024, allow collateral to remain in indexed strategy allocations where it can continue earning indexed credits, with maximum declared loan interest rates capped at 8.00% depending on the product. This is the loan structure that creates the operating conditions for your cash value to grow even while you are using the proceeds.
Non-Participating (Fixed) IUL Loans
A non-participating loan, also called a fixed loan, moves your cash value collateral out of the indexed account and into a fixed account that earns a declared rate set by the insurer. Because the collateral is no longer in the indexed crediting strategy, it cannot benefit from index-linked growth during the loan period. The fixed crediting rate on the collateral and the loan interest rate are often close to each other, which means the net spread is minimal and positive arbitrage is typically absent.
Fixed loans are simpler and more predictable in their cost structure, which has its own value for certain planning needs. However, if the strategic goal of taking an IUL loan is to access capital without interrupting the compounding trajectory of your cash value, the participating loan structure is the mechanism that makes that objective possible and the non-participating structure is the one that does not.

The Risk Side of IUL Loans: What to Understand Before You Borrow
A complete picture of IUL loans requires addressing what happens when they are mismanaged. If an IUL loan is never repaid, the outstanding balance accumulates loan interest annually and that compounding balance is continuously deducted from the policy’s death benefit. A loan of $25,000 at 5% annual loan interest grows to approximately $66,332 over twenty years if left entirely untouched, according to standard compound interest calculations. If the accumulated loan balance eventually exceeds your remaining cash value, your policy can lapse.
A lapsed policy with an outstanding IUL loan triggers a taxable event. According to IRS Publication 525, when a life insurance policy lapses or is surrendered and the cancellation of the policy debt creates a gain above the policy’s adjusted basis, that gain is treated as ordinary income in the tax year the lapse occurs. What was functioning as a tax-free IUL loan can become an unexpected and significant tax liability if the policy is not actively managed.
This is precisely why Dr. Taiwo Akindahunsi incorporates structured IUL loan review cycles into T-Bridge Finance LLC‘s ongoing service relationship with every client who carries an outstanding policy loan, because neglected IUL loans are one of the most preventable sources of financial loss in a well-designed insurance plan.
Who Benefits Most from IUL Loans?
IUL loans are most strategically valuable for individuals who have held their policy long enough to build meaningful cash value, typically three to five years or more at sufficient premium levels, and who have a specific, time-bound capital need that would otherwise require taxable income or high-interest consumer debt. High-income professionals, small business owners, and diaspora investors who hold indexed universal life policies as part of a broader tax-advantaged financial plan are the client profiles that T-Bridge Finance LLC most regularly advises on IUL loan strategy.
What T-Bridge Finance LLC consistently observes among clients who make strong use of participating IUL loan structures is that the decision to borrow from a policy rather than from a bank or retirement account is not primarily about the interest rate, it is about not interrupting compounding. Withdrawing funds from a 401(k) removes them from their growth environment. A participating IUL loan leaves the underlying asset fully active, which is a qualitatively different financial position even when the net rate differential is modest.
Dr. Taiwo Akindahunsi brings years of experience to each client engagement on insurance planning and IUL loan strategy at T-Bridge Finance LLC, and that depth of case-by-case analysis is what determines whether an IUL loan is the right tool for a specific situation or whether another vehicle better serves the client’s goals.

FAQ
1. What is an IUL loan in simple terms?
An IUL loan is money advanced by your life insurance carrier using your policy’s accumulated cash value as collateral. You receive funds without your cash value being withdrawn, and if the policy uses a participating loan structure, the cash value may continue earning index-linked interest credits while the IUL loan is outstanding. The loan proceeds are generally not taxable income as long as the policy remains in force.
2. How do IUL loans work when the loan is outstanding?
Once an IUL loan is disbursed, the carrier holds a collateral claim against your cash value. In a participating loan structure, that cash value stays in the indexed strategy and can continue earning credits tied to a market benchmark. In a fixed loan structure, the collateral moves to a declared-rate account and loses its indexed growth potential. The economic outcome depends on which loan structure your policy uses and how the market index performs during the loan period.
3. What is the typical IUL loans interest rate?
IUL loan interest rates vary by carrier, loan type, and policy design. Participating variable loans are often tied to an external economic index such as Moody’s Corporate Bond Index, and the rate may fluctuate monthly. Participating declared loans from some carriers carry a maximum rate of up to 8.00% set by the insurer. Fixed loan rates generally range between 5% and 8%. You should confirm your specific policy’s IUL loan interest rate terms directly with your carrier or a licensed advisor.
4. Do IUL loans affect my credit score?No. IUL loans are not reported to credit bureaus, require no credit check, and do not appear on your credit profile. The insurer extends the loan based entirely on your policy’s cash value collateral, which means accessing an IUL loan does not affect your creditworthiness or your ability to qualify for other financing.
5. What happens if I never repay my IUL loan?
If an IUL loan is never repaid, the outstanding balance plus compounding interest reduces your death benefit over time. If the loan balance grows to exceed your remaining cash value, the policy may lapse. A lapsed policy with an outstanding IUL loan triggers a taxable event under IRS guidelines, converting the gain portion of the loan proceeds into ordinary income in the year of the lapse. Active loan monitoring and a structured repayment approach are essential safeguards.
