Understanding the Interbank Rate in Ghana's Financial System

The interbank rate is the interest rate at which banks lend to each other on a short-term basis, typically overnight. It plays a crucial role in the liquidity management of banks and acts as a benchmark for various lending and deposit rates in the broader economy. Ghana’s interbank rate is directly influenced by the central bank’s policy rate, which is used as a tool to control inflation, stabilize the currency, and ensure financial system stability.

In 2023, Ghana’s interbank rate averaged 29.6%, a marked increase from previous years. This reflects the broader economic challenges Ghana faces, including persistent inflationary pressures, currency depreciation, and high levels of public debt. The interbank rate is an important tool in managing these macroeconomic challenges by influencing liquidity in the banking sector.

Key Drivers Behind the Rising Interbank Rate in Ghana

1. Inflation Control: One of the primary reasons behind the increase in the interbank rate is the high inflation rate, which peaked at over 40% in 2023. The Bank of Ghana has been aggressively raising interest rates to curb inflation, and the interbank rate has risen in tandem.

2. Cedi Depreciation: The Ghanaian cedi lost over 20% of its value in 2023, which prompted the central bank to raise rates to stabilize the currency. A higher interbank rate discourages excessive liquidity and supports the exchange rate by attracting foreign capital.

3. Monetary Policy: The Bank of Ghana’s decision to raise the policy rate to 30% in 2023 has had a direct impact on the interbank rate. Commercial banks respond by adjusting their short-term lending rates in the interbank market, leading to higher costs of borrowing for banks.

4. Liquidity Management: Banks use the interbank market to manage short-term liquidity needs. When liquidity is tight, the interbank rate rises as demand for funds increases. The current high rate reflects a constrained liquidity environment, exacerbated by economic uncertainty.

5. Government Borrowing: Ghana’s high levels of public debt and borrowing needs have pushed interest rates higher, including in the interbank market. The government’s need to finance its debt obligations has led to increased competition for funds, raising interbank rates.

Economic Implications of a High Interbank Rate

A high interbank rate has both positive and negative implications for the economy. On the positive side, a higher rate helps control inflation and stabilize the currency by restricting excessive liquidity. It also signals a commitment by the Bank of Ghana to maintain a tight monetary policy, which can boost investor confidence.

However, the downside is that higher interbank rates also increase borrowing costs for commercial banks, which pass these costs on to consumers and businesses through higher lending rates. In 2023, lending rates reached over 35%, making credit more expensive and dampening investment and consumption. This can slow economic growth in the short term, although it may help stabilize the economy in the long run.

Current Top 10 Factors Impacting Ghana's Interbank Rate:

1. Inflation Rates.
2. Bank of Ghana Policy Rate Adjustments.
3. Currency Depreciation (Cedi).
4. Liquidity Conditions in the Banking Sector.
5. Public Debt Levels and Government Borrowing.
6. Global Interest Rate Environment.
7. Capital Inflows and Foreign Exchange Reserves.
8. Political and Fiscal Stability.
9. Monetary Policy Alignment with IMF Programs.
10. Competition Among Banks for Short-Term Funds.

Projections and Recommendations:

Looking ahead, Ghana’s interbank rate is expected to remain elevated in the short term, as inflation and currency pressures persist. However, with effective monetary policy and external financial support, the rate could stabilize by late 2024. If inflation moderates and the cedi strengthens, the interbank rate could gradually fall to around 25-28%.

Recommendations for policymakers include:

• For the Bank of Ghana: Continue monitoring inflationary trends and adjust the policy rate accordingly to maintain economic stability while ensuring adequate liquidity in the banking sector.
• For Commercial Banks: Focus on efficient liquidity management and reduce reliance on short-term interbank borrowing by exploring longer-term funding options.
• For Investors: Take advantage of high-yield opportunities in the bond market but be cautious of potential volatility due to high interest rates.

Conclusions:

Ghana’s interbank rate plays a pivotal role in the country’s financial system, influencing liquidity management, lending rates, and overall economic stability. The sharp rise in the rate in 2023 reflects the broader macroeconomic challenges Ghana faces, particularly inflation and currency depreciation. While the high rate serves as a tool to stabilize the economy, it also poses challenges for borrowers and may dampen economic growth in the short term. Going forward, a balanced monetary policy will be key to managing these challenges and ensuring a stable interbank market.
