M3 money supply growth of 25.8% reflecting financial deepening
The external position improved substantially, with foreign exchange reserves reaching USD 6,329 million (equivalent to 4.9 months of import cover) and a narrower current account deficit. This external strength, combined with declining global fuel prices, contributed to stable inflation within the Bank of Tanzania's 3-5% target range.
These fundamentals fostered a liquid, confident financial system evident in active government securities markets and robust interbank cash market activity. Strong demand for Treasury instruments reflected investor trust in macroeconomic stability, low inflation, and accommodative monetary policy (CBR at 5.75%), enabling cost-effective domestic financing for development priorities like infrastructure under the Fifth Phase Development Plan (FYDP III).

2. Interbank Cash Market (IBCM)
The interbank cash market continued to play a critical role in short-term liquidity redistribution among banks, closely aligned with the Central Bank Rate (CBR). The IBCM serves as a vital mechanism for banks to manage their daily liquidity positions, facilitating the efficient allocation of surplus funds from cash-rich institutions to those experiencing temporary shortfalls.
In December 2025, the IBCM witnessed extraordinary growth and deepening, reflecting enhanced banking sector confidence, improved liquidity circulation, and the effectiveness of the Bank of Tanzania's monetary policy framework. The market's performance demonstrated the financial system's maturity and the strengthening of interbank relationships.
Interbank Cash Market Activity
Market turnover in the IBCM experienced remarkable expansion during December 2025, surging to unprecedented levels that signaled robust liquidity conditions and active trading among financial institutions.

Key Insight: Interbank Market Turnover
The sharp increase in turnover indicates improved liquidity circulation and stronger interbank confidence. The near-doubling of month-on-month activity (95.5% increase) and more than doubling year-on-year (115.3% increase) reflects several positive developments: enhanced trust among financial institutions, effective reverse repo operations by the Bank of Tanzania (TZS 1,419.3 billion), robust private sector credit growth (23.5%), and overall banking sector health. This exceptional growth demonstrates the IBCM's increasing importance as a liquidity management tool for Tanzania's financial institutions.
The tenor structure of interbank transactions reveals important insights about liquidity management preferences and monetary policy alignment. The distribution of transaction tenors demonstrates how banks strategically manage their short-term funding needs in alignment with the Bank of Tanzania's policy framework.

Key Insight: Transaction Tenor Structure
The dominance of 7-day transactions (39.9% of total) shows alignment with the Bank of Tanzania's liquidity management framework and policy signalling horizon. This concentration reflects strategic planning by financial institutions, matching the BoT's typical open market operations cycle and the CBR signaling period. The preference for 7-day tenors over overnight funding indicates confidence in near-term liquidity positions and reduces the operational burden of daily refinancing. This maturity profile supports more stable and predictable liquidity management across the banking sector.

Key Insight: Monetary Policy Transmission
Interbank rates remained close to the CBR, confirming effective monetary policy transmission and adequate liquidity conditions. The IBCM rate of 6.29% staying within the policy corridor of ±2 percentage points around the 5.75% CBR demonstrates that the Bank of Tanzania's monetary policy signals are effectively transmitted to the interbank market. This close alignment indicates: (1) adequate systemic liquidity without excess or scarcity, (2) successful open market operations by the BoT, (3) market confidence in the policy framework, and (4) efficient price discovery in the interbank market. The stability of rates supports predictable borrowing costs for banks and contributes to overall financial system stability.
The comprehensive analysis of Tanzania's government securities market and interbank cash market in December 2025 reveals a financial system operating at peak efficiency, characterized by exceptional liquidity, strong investor confidence, and effective monetary policy transmission. These market dynamics provide robust support for both fiscal operations and monetary policy effectiveness in Tanzania.
In December 2025, Tanzania's financial markets demonstrated extraordinary strength across all key indicators. The oversubscribed auctions for both Treasury Bills (1.94x) and 20-year Treasury Bonds (3.44x), combined with surging interbank cash market turnover (TZS 3,481.9 billion, representing a 95.5% month-on-month increase), highlighted three critical achievements:
💰
Ample Liquidity
Banking sector liquidity remained abundant, enabling robust market activity and supporting credit expansion to the private sector at 23.5% growth.
📈
Investor Confidence
Exceptional demand for government securities across all tenors reflects strong confidence in macroeconomic stability and fiscal sustainability.
🎯
Policy Effectiveness
Interbank rates staying within the CBR corridor confirm effective monetary policy transmission and central bank credibility.
💼
Reduced Borrowing Costs
Declining yields (T-bills to 5.87%, bonds easing to 12.02%) enable efficient financing for infrastructure and development under FYDP III.
Strategic Implication: This financial market strength bolsters Tanzania's macroeconomic stability, supporting sustained GDP growth projections of 6.3% for 2026. The liquid and efficient government securities market enables the government to finance development priorities at competitive rates, while the deepening interbank market enhances financial sector resilience and supports monetary policy effectiveness. Together, these factors position Tanzania's financial system to effectively support economic transformation objectives under the Fifth Phase Development Plan.
