The data on lending and deposit interest rates from the Bank of Tanzania's Monthly Economic Review (September 2025) indicate a gradual easing in borrowing costs amid stable savings returns, aligning with the broader monetary policy shift following the Central Bank Rate (CBR) cut to 5.75% in July 2025. This occurs against a backdrop of robust economic momentum, with Q3 2025 GDP growth estimated above 6% (driven by agriculture, mining, and construction) and headline inflation at a benign 3.4%. The narrowing interest rate spread suggests improving financial intermediation efficiency, which could sustain private sector credit expansion (16.2% y-o-y in August). Drawing from the document and recent analyses, these trends imply enhanced affordability of credit, bolstering investment and consumption while mitigating risks from global uncertainties like elevated policy volatility.

When contextualized with international outlooks, such as the IMF's projection of 6% GDP growth and 4% inflation for 2025, and the World Bank's upgraded Sub-Saharan Africa forecast to 3.8% (with Tanzania as a regional outperformer), the rate dynamics signal a supportive environment for inclusive development. However, persistently high lending rates (above 15%) could still constrain SME access, potentially capping growth below potential if not addressed through further reforms.

Implications for Tanzania's Economic Development

1. Lending Rates: Gradual Easing to Fuel Investment, But High Levels Pose Affordability Challenges

• Key Observations Recap: The overall TZS lending rate dipped to 15.07% (from 15.16% in July), with short- and medium-term rates stable around 15-16%. Longer-term rates (3+ years) trended lower at 14-14.22%, while prime (negotiated) rates edged up to 12.72%. This follows a broader decline from 15.23% in June, per earlier reviews.
• Implications for Economic Development:
  • Boost to Private Sector Expansion: The modest easing enhances credit affordability, directly supporting the 16.2% y-o-y private credit growth noted in the document, particularly in high-impact sectors like agriculture (30.1%) and trade (29.2%). Lower long-term rates could accelerate infrastructure financing, such as renewable energy projects or agricultural mechanization, aligning with Tanzania's FY2024/25 growth of 5.6% driven by these areas. The Deloitte East Africa Outlook (2025) highlights that such rate cuts foster fixed investment optimism, potentially drawing foreign direct investment (FDI) up 10-15% in services and mining.
  • Inclusive Growth Potential: Personal loans (36% of credit) for MSMEs stand to benefit, aiding job creation in a context of 5.5% unemployment. However, rates above 15% remain elevated regionally (e.g., vs. Kenya's 13-14%), which a ResearchGate study links to slowed consumer spending and higher commodity costs, risking a 0.5-1% drag on GDP if unmitigated.
  • Risks: The slight uptick in prime rates may signal selective tightening for low-risk borrowers, potentially widening inequality in credit access. Amid moderating global oil prices (Chart 1.5), sustained high rates could amplify imported inflation pass-through to transport costs (1.4% inflation component).

2. Deposit Rates: Stability with Upside for Savings Mobilization

• Key Observations Recap: Savings rates held at 2.90%, while overall time deposits fell slightly to 8.61% (from 8.83%). Shorter maturities (1-2 months) offered 10-10.7%, dropping to 7.16% for 24 months; negotiated rates rose to 10.99% (from 10.72%).
• Implications for Economic Development:
  • Strengthened Banking Liquidity and Funding: Rising negotiated rates attract institutional savers (e.g., pensions), funding the 21% M3 money supply growth and reducing reliance on costly interbank borrowing (IBCM rates at 6.48%). This ties into the SECO Economic Report (2025), where deposit rates averaged 8.14% annually, supporting 15.1% private credit expansion and financial deepening (bank deposits at 25% of GDP).
  • Encouraging Household Savings: Unchanged low savings rates may deter retail savers amid 3.4% inflation, but competitive time deposit yields (up y-o-y) promote formal savings, crucial for resilience against food price shocks (7.7% food inflation). The World Bank's January 2025 prospects note that easing rates overall will rebound household consumption by 2-3% in 2025, as savers shift to productive investments.
  • Risks: The dip in longer-term deposits could signal caution on inflation outlook, potentially limiting banks' long-term lending capacity if global commodity pressures (e.g., elevated fertilizers) erode confidence.

3. Interest Rate Spread: Narrowing Margins Signal Efficiency Gains

• Key Observations Recap: The short-term spread (1-year lending minus deposit) tightened to 5.66 percentage points (from 6.68 pp in August 2024), reflecting faster deposit rate adjustments than lending.
• Implications for Economic Development:
  • Improved Financial Intermediation: A narrower spread indicates better policy transmission from the CBR cut, pressuring banks to optimize costs and pass on benefits to borrowers. This supports the document's liquidity improvements (via reverse repos), fostering a 23.2% broad money (M2) growth and efficient resource allocation to growth sectors.
  • Bank Profitability and Stability: While margins compress (potentially squeezing net interest income by 0.5-1%), it encourages non-lending revenue diversification (e.g., fees), enhancing sector resilience. A RePEc study on Tanzania notes that govt borrowing crowds out spreads, but current trends mitigate this, aiding fiscal-monetary coordination for 4.5% deficit financing.
  • Risks: Further narrowing could raise non-performing loans if banks cut risky lending, per the ResearchGate analysis, especially in agriculture vulnerable to weather (e.g., El Niño echoes).

Overall Summary and Forward Outlook

These rate movements imply a pro-cyclical boost to Tanzania's development: easing lending costs and mobilizing deposits sustain credit-driven growth (targeting 6% GDP), while the narrowing spread enhances efficiency amid low inflation risks. This aligns with the IMF's 2025 staff report praising policy easing for strong activity (5.5% in 2024, accelerating), and the World Bank's emphasis on lower rates spurring consumption and FDI. Compared to EAC peers (e.g., Uganda's wider 7-8 pp spreads), Tanzania's metrics underscore competitive advantages.

Yet, high baseline lending rates highlight needs for structural reforms like digital lending to cut costs 2-3%. If global trends hold (e.g., SSA inflation easing per WB), Q4 2025 could see further declines, pushing annual growth to 6.2-6.5%. Monitor debt dynamics, as domestic borrowing (TZS 1,644 bn in August) could reverse spreads if issuance accelerates.

In April 2025, Tanzania’s banking sector exhibited stable yet dynamic interest rate trends, reflecting a competitive financial environment. The overall lending rate eased to 15.16% from 15.50% in March 2025, enhancing credit access, while the short-term lending rate rose slightly to 16.15%, indicating cautious short-term lending. Deposit rates showed mixed trends, with the 12-month deposit rate increasing to 9.27% from 8.14%, incentivizing long-term savings, and negotiated deposit rates rising to 10.52%. The interest rate spread narrowed to 6.88% from 7.72% a year earlier, signaling improved banking efficiency. The following table summarizes these key figures.

1. Lending Interest Rates (April 2025)

Lending interest rates reflect the cost of borrowing from commercial banks, influencing credit access for businesses and individuals. The provided data shows a stable yet slightly easing lending environment.

Key Figures:

Analysis:

• Overall Lending Rate: The decline from 15.50% in March 2025 to 15.16% in April 2025 (a 0.34 percentage point drop) indicates a marginal easing of borrowing costs. This aligns with the stable Central Bank Rate (CBR) of 6% maintained by the Bank of Tanzania (BoT) in April 2025 (Monthey Economic Review), suggesting a cautious monetary policy to support economic growth while managing inflation (3.2% in April 2025). Compared to April 2024 (15.51%), the rate is down by 0.35 percentage points, reflecting a gradual trend toward lower borrowing costs.
• Short-term Lending Rate: The increase from 15.83% in March 2025 to 16.15% in April 2025 (up 0.32 percentage points) suggests banks are charging slightly more for loans with maturities up to one year. This could reflect higher perceived risk or demand for short-term credit, possibly linked to seasonal economic activities (e.g., agricultural trade, as food stocks rose to 557,228 tonnes). Compared to April 2024 (16.17%), the rate is nearly stable, with a minor decrease of 0.02 percentage points.
• Negotiated Lending Rate: The slight decline from 12.94% in March 2025 to 12.88% in April 2025 (down 0.06 percentage points) and a more significant drop from 13.46% in April 2024 (down 0.58 percentage points) indicates that prime or large borrowers (e.g., corporations or institutional clients) benefit from more favorable terms. This aligns with TICGL noting negotiated rates for prime borrowers averaging around 12.77%–12.79% in late suggesting continued flexibility for high-value clients.

Insights:

• The slight decline in the overall lending rate to 15.16% suggests improved access to credit, supporting economic activities like investment and consumption. The Monthey Economic Review notes a projected GDP growth of 6% in 2025, which may be bolstered by these lower borrowing costs.
• The rise in short-term lending rates to 16.15% could indicate banks’ caution in extending short-term credit, possibly due to seasonal liquidity demands or minor risk concerns, despite stable macroeconomic conditions (inflation at 3.2%).
• The lower negotiated rates (12.88%) reflect banks’ willingness to offer competitive terms to prime borrowers, likely to support key sectors like manufacturing or trade, as noted in the diversified loan portfolio.

Source Context:

• TICGL indicate that lending rates have been relatively stable, with November 2024 rates at 15.67% overall and 12.77% negotiated, consistent with the April 2025 trend of gradual declines. Historical data shows lending rates at 16.68% in 2020, suggesting a long-term downward trend from higher historical averages (19.78% from 1992–2020).

2. Deposit Interest Rates (April 2025)

Deposit interest rates reflect the returns offered by banks to attract savings, influencing liquidity and consumer behavior.

Key Figures:

Analysis:

• Savings Deposit Rate: The slight increase from 2.86% in March 2025 to 2.89% in April 2025 (up 0.03 percentage points) and from 2.70% in April 2024 (up 0.19 percentage points) suggests banks are marginally increasing incentives for savings accounts. This aligns with TICGL noting a rise in savings deposit rates to 3.02% in August 2024, indicating a trend of encouraging household savings.
• Overall Time Deposit Rate: The decline from 8.00% in March 2025 to 7.82% in April 2025 (down 0.18 percentage points) but an increase from 7.55% in April 2024 (up 0.27 percentage points) reflects a mixed trend. The monthly decline suggests eased liquidity pressure, as banks may have sufficient deposits, consistent with the Monthey Economic Review’s indication of high liquidity in the banking sector (evidenced by Government Securities Market oversubscription, previous responses).
• 12-month Deposit Rate: The significant rise from 8.14% in March 2025 to 9.27% in April 2025 (up 1.13 percentage points) and from 8.94% in April 2024 (up 0.33 percentage points) indicates banks are offering higher returns for longer-term deposits to lock in funds. This contrasts with TICGL noting a decline to 8.18% overall deposit rates in November 2024, suggesting a strategic shift toward long-term deposits by April 2025.
• Negotiated Deposit Rate: The increase from 10.35% in March 2025 to 10.52% in April 2025 (up 0.17 percentage points) and from 9.59% in April 2024 (up 0.93 percentage points) shows banks are competing for large or institutional deposits. This aligns with TICGL reporting negotiated deposit rates at 10.14% in November 2024, indicating a continued upward trend.

Insights:

• The rise in savings (2.89%) and 12-month deposit rates (9.27%) suggests banks are incentivizing long-term savings, possibly to support lending activities or manage liquidity, as deposits are a primary funding source.
• The decline in overall time deposit rates to 7.82% reflects ample liquidity, reducing the need to aggressively attract deposits, consistent with the Monthey Economic Review’s note of high banking sector liquidity (e.g., TZS 2,611.1 billion in Interbank Cash Market transactions, previous responses).
• Higher negotiated deposit rates (10.52%) indicate competition for large depositors, likely institutional clients or pension funds, which hold significant domestic debt (26.5% by pension funds).

Source Context:

• TICGL confirm a trend of rising deposit rates, with January 2025 rates at 10.08%, up from a historical average of 9.12% (2016–2025). The April 2025 negotiated rate of 10.52% continues this upward trend, reflecting banks’ efforts to attract deposits amid strong credit demand.

3. Interest Rate Spread

The interest rate spread, defined as the difference between lending and deposit rates, indicates banking sector efficiency and credit risk perceptions.

Key Figures:

• Short-term Interest Rate Spread:
  • April 2025: 6.88 percentage points
  • April 2024: 7.72 percentage points
  • Change: Decrease of 0.84 percentage points

Analysis:

• Declining Spread: The reduction from 7.72% in April 2024 to 6.88% in April 2025 indicates a more competitive and efficient banking system. This aligns with TICGL noting a narrowing spread to 5.93% in November 2024, suggesting continued improvement. The spread is calculated as the difference between the short-term lending rate (16.15%) and a corresponding deposit rate (e.g., 12-month deposit rate of 9.27%), yielding 6.88 percentage points.
• Implications: A narrower spread suggests lower credit risk perceptions and increased competition, as banks charge less of a premium on loans while offering better returns to depositors. This is supported by the Monthey Economic Review’s stable macroeconomic environment (inflation at 3.2%, CBR at 6%) and TICGL noting reduced credit risk.
• Context: The document’s indication of high liquidity in the Government Securities Market (e.g., TZS 1,076.7 billion in bond bids, previous responses) and Interbank Cash Market (TZS 2,611.1 billion) supports efficient liquidity management, contributing to the narrower spread.

Source Context:

• TICGL confirm a trend of narrowing spreads, with August 2024 at 6.68% and November 2024 at 5.93%, reflecting improved banking efficiency. The April 2025 spread of 6.88% is slightly higher but consistent with this trend.

Conclusion

In April 2025, Tanzania’s lending and deposit interest rates reflected a stable and competitive financial sector. The overall lending rate eased to 15.16%, benefiting borrowers, while short-term rates rose slightly to 16.15%, indicating caution in short-term lending. Negotiated lending rates (12.88%) favored prime borrowers. Deposit rates showed mixed trends, with savings (2.89%) and 12-month rates (9.27%) rising, incentivizing long-term savings, while overall time deposit rates fell to 7.82%, reflecting ample liquidity. The interest rate spread narrowed to 6.88% from 7.72%, signaling improved efficiency and reduced credit risk. These trends align with the Monthey Economic Review’s stable monetary policy (CBR at 6%) and moderate inflation (3.2%), supporting economic growth projected at 6% in 2025. The following table summarizes these key figures.

The table is designed to present the data clearly and concisely, including comparisons with March 2025 and April 2024, as well as the interest rate spread, wrapped in an artifact tag as per the guidelines.

In March 2025, Tanzania’s financial system experienced a moderate tightening in borrowing conditions, with the overall lending rate rising to 15.50%, up from 15.14% in February 2025. Short-term loans (up to 1 year) averaged 15.83%, while medium-term loans (1–3 years) rose above 16%, reflecting higher credit risk pricing. In contrast, negotiated lending rates for prime borrowers declined to 12.94% from 13.42%, indicating competitive conditions for low-risk clients. On the deposit side, returns eased due to improved liquidity, with the 12-month deposit rate dropping sharply to 8.14% from 9.48%, and the negotiated deposit rate falling to 10.35% from 11.40%. Consequently, the interest rate spread widened to 7.69 percentage points, compared to 6.29 points in February, highlighting growing bank profit margins and a cautious credit outlook.

1. Lending Interest Rates (TZS Loans)

Interpretation: Lending rates rose slightly across most loan durations in March 2025, reflecting cautious pricing due to liquidity costs and credit risk. However, negotiated rates (for prime borrowers) declined, indicating banks' willingness to offer competitive rates to low-risk clients.

2. Deposit Interest Rates (TZS Deposits)

Interpretation: Deposit rates declined slightly, particularly the 12-month and negotiated deposit rates, due to improved liquidity conditions in the banking system, reducing banks' need to compete for deposits.

3. Short-Term Interest Rate Spread

• The interest rate spread (difference between short-term lending and deposit rates) widened to 7.69 percentage points in March 2025, from 6.29 in February and 7.23 in March 2024.

Implication: A widening spread suggests improved bank profitability on new lending, but may also imply tighter borrowing conditions for depositors.

In March 2025, lending interest rates slightly increased, while deposit rates softened due to ample liquidity. The negotiated lending rate dropped to 12.94%, showing room for favorable terms for low-risk borrowers. These trends reflect active monetary management and a stable credit environment.

What the Figures Tell Us

1. Borrowing Costs Are Slightly Rising

• The overall lending rate increased from 15.14% in February to 15.50% in March 2025.
• Rates for short- and medium-term loans also rose.
• 👉 This suggests that banks are charging more for credit, possibly due to:
  • Inflation expectations,
  • Higher demand for credit,
  • Or cautious risk pricing.

2. Preferred (Low-Risk) Borrowers Still Get Better Deals

• The negotiated lending rate fell from 13.42% to 12.94%.
• 👉 This means banks are competing more for large or safe borrowers, such as corporates or government clients, by offering lower rates.

3. Depositors Are Getting Lower Returns

• Deposit rates fell slightly:
  • 12-month deposit rate dropped from 9.48% to 8.14%.
  • Negotiated deposit rate declined from 11.40% to 10.35%.
• 👉 This indicates that banks are less pressured to attract new deposits, thanks to improved liquidity in the system.

4. Wider Interest Rate Spread = Higher Bank Profit Margins

• The interest rate spread (gap between lending and deposit rates) increased to 7.69% in March from 6.29% in February.
• 👉 A higher spread often means better margins for banks, but it also signals higher borrowing costs for the public compared to the returns they earn from savings.

Overall Interpretation

The data shows a stable but cautious banking environment in Tanzania. Banks are raising lending rates slightly to manage risks and inflation, while lowering deposit rates as liquidity improves. However, prime borrowers still enjoy favorable terms, and banks are earning more from the gap between what they pay and what they charge.
