Rising Interbank Rates Signal Tighter Liquidity

The interbank market in Vietnam has seen a sharp increase in average interest rates across most short-term maturities, according to recent data. Overnight rates climbed by 7.5%, reaching 12% annually, while one-week rates rose 6.1% to 11.6% annually. The two-week rate remained stable at 7.45% annually, and the one-month rate increased slightly by 0.3% to 7.75% annually. These spikes reflect a tightening of liquidity in the financial system, driven by heightened demand for short-term funding among banks.

To counter the rising rates, the State Bank of Vietnam (SBV) injected 90,000 billion VND into the market through the Open Market Operation (OMO). The funds were allocated across three maturities: 7 days (35,000 billion VND), 14 days (40,000 billion VND), and 56 days (15,000 billion VND), all at a uniform rate of 4.5% annually. The SBV emphasized that the full amount of the auction was subscribed, indicating strong demand from financial institutions for liquidity.

Despite the injection, the net inflow of 31,033 billion VND into the repo market raised concerns about the effectiveness of the SBV’s measures. With 58,967 billion VND in maturing instruments, the central bank’s decision not to issue new securities further tightened liquidity. This has led to a surge in the total amount of funds circulating through the repo market, now standing at 275,704 billion VND. However, the SBV’s efforts to stabilize the market remain under scrutiny as the interbank rates continue to climb.

Analysts Highlight Systemic Liquidity Pressures

According to Chứng khoán Vietcombank (VCBS), liquidity and capital adequacy pressures have been intensifying since mid-2025, exacerbating the challenges faced by the banking sector. The reduced liquidity buffers at several banks, particularly smaller institutions, have limited their capacity to absorb short-term shocks. This has forced banks to rely more heavily on the interbank market for funding, which now carries higher costs due to the elevated rates.

The analysts warn that the limited flexibility to manage liquidity risks is creating a precarious situation for financial institutions. With the interbank rates at historic highs, banks are struggling to balance their funding costs and maintain profitability. The reliance on short-term borrowing has also increased the risk of liquidity crunches, especially for smaller banks that lack the depth of capital to weather prolonged periods of tight credit conditions.

The situation is further complicated by the fact that the interbank rates are not only influencing the cost of borrowing for banks but also affecting the broader financial ecosystem. As banks pass on these higher costs to their customers, the interest rates on savings and loans are rising, which could dampen consumer and business spending. This dynamic is creating a feedback loop that could further strain the financial system if not addressed proactively.

Central Bank Tightens Regulations to Stabilize Financial Markets

In response to the volatile interbank rates, the SBV has issued directives to ensure compliance with its macroeconomic stability goals. The central bank has mandated that banks prioritize measures to stabilize interest rates, adhere to publicized deposit rates, and maintain transparent reporting on lending spreads. These regulations aim to prevent the escalation of market distortions and ensure that the financial system remains resilient to external shocks.

The SBV has also emphasized the need for banks to enhance internal oversight and enforce strict compliance with interest rate guidelines. Non-compliance with these measures could result in severe penalties, underscoring the central bank’s commitment to maintaining order in the financial markets. Additionally, banks are required to disclose their average lending rates, the spread between deposit and lending rates, and details of credit programs on their websites to improve transparency for customers and businesses.

Beyond regulatory compliance, the SBV has directed banks to focus on balancing their capital usage and maintaining adequate liquidity. This includes directing credit flows toward priority sectors such as production, infrastructure, and growth drivers, while ensuring the safety of the broader financial system. The central bank’s strategy highlights a dual focus on both short-term stabilization and long-term structural reforms to safeguard the stability of the financial sector.

CONCLUSION

The surge in interbank rates in Vietnam reflects a complex interplay of liquidity pressures, regulatory interventions, and market dynamics. While the SBV’s efforts to inject liquidity and stabilize the financial system are critical, the persistent high rates underscore the underlying challenges in the banking sector. Analysts warn that without sustained improvements in liquidity management and capital adequacy, the financial system could face further instability. The central bank’s regulatory measures, combined with banks’ adherence to transparency and compliance, will be key to navigating this turbulent period. As the market continues to evolve, the balance between short-term stabilization and long-term resilience will determine the trajectory of Vietnam’s financial landscape.
