Loan-to-Deposit Ratio: Bank Liquidity at a Glance
The loan to deposit ratio LDR is the simplest funding mix measure on a bank's balance sheet. It divides total loans by total deposits to show how much of the deposit base is deployed into lending. The ratio is also embedded in the Riegle-Neal Act host state LDR test that US regulators publish annually.
Key Takeaways
- Loan-to-deposit ratio equals total loans divided by total deposits, expressed as a percentage.
- The FDIC, OCC, and Federal Reserve publish host state LDRs each year for the Riegle-Neal interstate banking test.
- A ratio between 80% and 90% is generally considered a balanced range for diversified US banks.
- A high LDR with falling deposits signals reliance on wholesale funding and possible liquidity stress.

What It Is
The loan-to-deposit ratio (LDR) is a basic liquidity metric that has been used in US bank supervision since well before the modern Basel rules. It measures how aggressively a bank has converted its deposit funding into loans, and by extension how much liquidity remains in cash, securities, or wholesale funding capacity.
The federal banking agencies publish state-level LDRs each year under the Riegle-Neal Interstate Banking and Branching Efficiency Act. The test compares a host bank's interstate branches' LDR to the host state's average to discourage banks from using cross-state deposits without reinvesting locally.
The Intuition
A deposit is a low-cost, sticky source of funding. A loan is a higher-yielding asset, but illiquid. The LDR tells you how the bank is balancing the two sides. A low LDR (say, 60%) means the bank holds a lot of cash and securities relative to deposits, which is safer but lower-margin. A high LDR (say, 95%) means almost every deposit dollar is out the door as a loan, which is more profitable but leaves little buffer if deposits run.
A high LDR is not automatically bad. Some banks (notably commercial banks with deep wholesale funding access) operate above 100% LDR by funding the gap with debt and brokered deposits. The question is whether the bank can replace any lost core deposits at reasonable cost.
How It Works
The formula is straightforward.
LDR = Total Loans / Total Deposits
Most disclosures use period-end gross loans and total deposits, both from the balance sheet. Some analysts use net loans (gross minus allowance) or include held-for-sale loans, so confirm the basis when comparing across banks.
Typical interpretation bands:
Below 60% Excess liquidity, possibly under-lent or in transition
60% to 80% Conservative liquidity, common for very large diversified banks
80% to 90% Balanced, typical core-funded regional bank
90% to 100% Aggressive, growing reliance on non-deposit funding
Above 100% Wholesale-funded model, dependent on capital markets
US regional banks typically run between 75% and 90%. The largest universal banks often run lower (60% to 75%) because they hold large trading and securities portfolios that are not lending. Investment-bank-heavy holding companies can post LDRs near 50%.
Worked Example
Consider three banks at the same date.
Bank A (large universal) Bank B (regional) Bank C (specialty)
Total loans $ 1,000 B $ 60 B $ 25 B
Total deposits $ 1,500 B $ 70 B $ 20 B
LDR 66.7% 85.7% 125.0%
Wholesale funding share 5% 12% 45%
LCR (estimated) 130% 115% 95% (below standard)
Bank A is a universal with deep trading and securities books; its LDR is naturally low. Bank B is a typical regional; its LDR sits in the balanced band. Bank C is loan-heavy and funds the gap with brokered CDs and FHLB advances; its LDR above 100% reflects a wholesale-funded model.
In the 2023 regional bank failures, several institutions had LDRs in the 70% to 80% range that looked benign in isolation. The problem was concentrated uninsured deposits and large unrealized securities losses, not the LDR itself. The LDR is one signal, not a complete liquidity picture.
Common Mistakes
- Reading LDR as a complete liquidity measure. A low LDR does not mean a bank is safe. Concentration of deposits, securities losses, and wholesale dependence all matter.
- Comparing across business models without context. Universal banks, regional commercial banks, and specialty lenders all run different normal LDRs by design.
- Mixing gross and net loans. Some banks report on gross loans (industry standard), others on net of allowance. The difference is usually 1% to 2% of loans.
- Ignoring brokered deposits. A bank with a 95% LDR and 40% brokered deposits has very different liquidity than a peer at 95% LDR with 5% brokered. The composition matters.
- Treating the Riegle-Neal host state LDR as universally meaningful. The host state test is a specific interstate banking rule, not a general supervisory limit.
Frequently Asked Questions
What is the loan to deposit ratio LDR in simple terms? It is the share of a bank's deposits that have been turned into loans, expressed as a percentage. An LDR of 85% means the bank has deployed 85 cents of every deposit dollar into lending.
How does the LDR affect investment decisions? For bank equity investors, a rising LDR usually drives higher net interest income but increases reliance on non-deposit funding. For credit investors, a high LDR paired with thin liquid securities buffers raises the probability of stress in a funding squeeze.
What is a real-world example of LDR shifts? US aggregate LDRs fell from above 90% pre-2008 to near 65% during the deposit surge of 2020-2021, then climbed back into the mid-70s as the Fed raised rates and depositors moved to money market funds. The trajectory reflects funding pressure on the system.
How can investors use LDR disclosures effectively? Compare LDR to the bank's wholesale funding share, brokered deposit percentage, and LCR. A balanced LDR with low wholesale dependence is fundamentally different from the same LDR funded by capital markets.
How is the LDR different from the LCR? The LDR is a structural, point-in-time ratio of loans to deposits. The LCR is a regulatory 30-day stress test that prescribes outflow rates and qualifying liquid assets. The LDR is a high-level indicator; the LCR is a supervisory rule.
