What it means
A bank is an intermediary: it pays depositors one rate, lends at a higher rate and keeps the difference as its margin. Disintermediation happens when either side finds a better deal by stepping around that middle, for example a saver buying government bills directly or a company issuing bonds instead of borrowing from its bank.
The trigger is almost always a widening gap between what the intermediary pays and what the direct market offers. When deposit rates lag market rates badly, corporate treasurers and households move cash into money market funds and short-dated government paper, and bank funding shrinks.
For a business, the practical question is whether direct funding is genuinely cheaper once you count the work. Issuing bonds brings lower headline rates for large borrowers but adds arrangement fees, disclosure obligations and a covenant package that cannot be renegotiated over a phone call the way a bank facility often can.
The same word describes what happens outside finance, where a manufacturer selling directly to customers cuts out the distributor. The economics rhyme: the margin the middleman earned is split between the two remaining parties, and the functions the middleman performed, such as credit checks and inventory, do not vanish and must be absorbed by someone.
The nuance worth remembering is reintermediation. New middlemen usually appear in place of old ones, so a peer-to-peer lending platform, a fund manager or a payment processor ends up occupying the position the bank used to hold, often with lighter regulation.
Regulation also sets how far the shift can run. Deposit insurance, capital requirements and supervision apply to banks and frequently not to the newer channels replacing them, so part of the apparent gain for the saver is really a transfer of risk from an insured deposit to an uninsured one.
In practice
Real-world examples.
Example
A listed retailer with strong credit replaces a $250,000,000 syndicated bank loan with a bond issue priced 0.9 percentage points cheaper, saving $2,250,000 a year in interest. It accepts tighter public disclosure and a fixed repayment date in exchange for the saving, losing the flexibility to renegotiate quietly with a relationship lender.
Example
A savings-focused household moves $80,000 out of an instant access account paying 1.5% and into a money market fund yielding 4.4%, adding roughly $2,320 of annual interest before tax.
Example
A furniture manufacturer opens its own online store and ships directly to customers, keeping the 35% margin its wholesale partners used to take, while absorbing returns handling and customer service costs it never previously carried.
Formula
Calculation
Yield pickup from disintermediation = (direct market yield - intermediated yield) x amount moved
A company treasurer holds $5,000,000 in a business deposit account paying 1.2% while short-dated government bills yield 4.6%.
Interest on deposit: $5,000,000 x 1.2% = $60,000 a year
Interest on bills: $5,000,000 x 4.6% = $230,000 a year
Yield pickup: $230,000 - $60,000 = $170,000 a year
Seen from the bank's side, the loss is larger than the deposit interest saved. If the bank had been lending that money out at 6.0%, its margin was 6.0% - 1.2% = 4.8%, so it loses $5,000,000 x 4.8% = $240,000 of annual gross margin when the deposit walks.Case study
Seen in the real world.
Ridgeway Tools is an illustrative, invented manufacturer used to show the trade-offs. Its finance director noticed the firm was earning 1.1% on an average cash balance of $8,000,000 while the same bank charged 6.4% on its revolving facility, and decided to move most of the cash into a short-dated government bill ladder yielding 4.5%.
Moving $6,000,000 lifted interest income from $66,000 to $270,000 a year on that slice, a gain of $204,000. The bank responded within a quarter by offering a tiered deposit rate of 3.8% on balances above $2,000,000, which is what competitive pressure from disintermediation usually produces.
The illustrative twist was operational rather than financial. Ridgeway discovered that settling supplier payments from a bill ladder took two extra days, so it kept $2,000,000 in the bank for liquidity and accepted a slightly smaller gain in exchange for keeping its payment run simple.
Watch out
Common mistakes.
- Assuming the intermediary's margin is pure profit, when part of it pays for credit assessment, liquidity and payment infrastructure that someone still has to provide.
- Comparing a deposit rate with a market yield without allowing for the loss of instant access and deposit protection.
- Treating disintermediation as permanent, when new intermediaries usually emerge and capture much of the same margin.
Questions
People also ask.
Why do banks worry about disintermediation?
Because deposits are their cheapest source of funding, and when those deposits move to markets the bank must replace them with more expensive wholesale money.
Is disintermediation good for borrowers?
Often yes for large, well-rated borrowers who can access bond markets directly, but smaller borrowers usually still need an intermediary willing to assess their credit.
Does disintermediation only happen in finance?
No, the same pattern appears whenever a manufacturer sells directly to end customers or a service provider bypasses an agent or distributor.
