Introduction
When I first started exploring the world of interbank lending, I found myself overwhelmed by the jargon and complex mechanisms behind interest rates like LIBOR and LIBID. While LIBOR (London Interbank Offered Rate) often steals the spotlight, its lesser-known counterpart, the London Interbank Bid Rate (LIBID), plays an equally crucial role in financial markets. In this guide, I’ll break down LIBID, explain how it functions, and highlight its significance in the global banking system.

What Is LIBID?
LIBID represents the average interest rate at which major London banks are willing to borrow funds from other banks in the interbank market. Unlike LIBOR, which reflects the offered rate (what banks charge for lending), LIBID is the bid rate—the rate banks are willing to pay to secure short-term loans.
Key Differences Between LIBOR and LIBID
| Feature | LIBOR (Offered Rate) | LIBID (Bid Rate) |
|---|---|---|
| Definition | Rate banks charge for lending | Rate banks pay to borrow |
| Market Role | Reflects lending costs | Reflects borrowing demand |
| Calculation | Based on bank submissions | Based on actual transactions |
| Volatility | More sensitive to credit risk | Less volatile |
How LIBID Works
Interbank lending ensures financial institutions maintain liquidity. When a bank faces a short-term cash shortage, it borrows from another bank with excess reserves. The rate at which this borrowing happens is influenced by LIBID.
The Mechanics of LIBID
- Banks Submit Rates: Major banks report the rates they are willing to pay for deposits.
- Trimmed Average Calculation: The highest and lowest submissions are discarded, and the remaining rates are averaged.
- Publication: The final LIBID rate is published daily.
The formula for LIBID can be expressed as:
\text{LIBID} = \frac{\sum_{i=1}^{n} r_i - \text{Max}(r_i) - \text{Min}(r_i)}{n-2}Where:
- r_i = Submitted bid rates
- n = Number of contributing banks
Example Calculation
Suppose five banks submit the following bid rates for a 3-month deposit:
| Bank | Bid Rate (%) |
|---|---|
| Bank A | 2.15 |
| Bank B | 2.30 |
| Bank C | 2.10 |
| Bank D | 2.25 |
| Bank E | 2.05 |
- Remove Outliers: Discard the highest (2.30%) and lowest (2.05%).
- Average Remaining Rates:
Why LIBID Matters
1. Benchmark for Short-Term Borrowing Costs
LIBID helps banks determine the cost of securing overnight or short-term loans. A rising LIBID signals tightening liquidity, while a falling LIBID suggests excess reserves.
2. Influence on Derivatives and Loans
While LIBOR is more commonly referenced, LIBID impacts certain financial products, including:
- Floating-rate notes (FRNs)
- Interest rate swaps
3. Indicator of Banking Sector Health
A widening spread between LIBOR and LIBID (\text{Spread} = \text{LIBOR} - \text{LIBID}) indicates increased perceived credit risk.
Historical Context: LIBID vs. LIBOR
Before the 2008 financial crisis, LIBOR and LIBID spreads were narrow, reflecting high trust among banks. Post-crisis, the spread widened dramatically:
| Year | Avg. LIBOR (%) | Avg. LIBID (%) | Spread (%) |
|---|---|---|---|
| 2007 | 5.35 | 5.30 | 0.05 |
| 2009 | 1.10 | 0.90 | 0.20 |
| 2020 | 0.30 | 0.15 | 0.15 |
This shift highlighted counterparty risk concerns as banks became wary of lending to each other.
The Decline of LIBID and the Rise of SOFR
With the phasing out of LIBOR, alternative benchmarks like the Secured Overnight Financing Rate (SOFR) gained prominence. Unlike LIBID, SOFR is based on secured transactions (backed by Treasury collateral), reducing manipulation risks.
Comparing LIBID and SOFR
| Aspect | LIBID | SOFR |
|---|---|---|
| Basis | Unsecured interbank loans | Secured repo transactions |
| Risk Profile | Higher credit risk | Lower risk (collateralized) |
| Volatility | More sensitive to bank stress | More stable |
Practical Implications for Investors
1. Assessing Bank Stability
A sudden spike in LIBID suggests liquidity concerns. For example, during the 2008 crisis, LIBID surged as banks hoarded cash.
2. Pricing Short-Term Instruments
Money market funds and commercial paper rates often correlate with LIBID movements.
3. Transition to New Benchmarks
With LIBOR’s discontinuation, understanding LIBID’s legacy helps in adapting to SOFR and other alternatives.
Conclusion
While LIBID may not be as widely discussed as LIBOR, its role in interbank lending is indispensable. By understanding how it functions, investors and financial professionals can better navigate short-term funding markets. As the financial landscape evolves, transitioning to new benchmarks like SOFR will require a solid grasp of these foundational concepts.
