Nepal Fully Implements Interest Rate Corridor Structure: A Detailed Analysis

Nepal Rastra Bank (NRB) has marked a pivotal shift in its monetary policy operations by fully implementing the Interest Rate Corridor (IRC) framework starting from February 2024 (Fagun 2080 BS). This reform aims to enhance liquidity management, anchor short-term interest rates, and drive stable and sustainable economic growth.

Nepal’s journey toward modern liquidity management has been long and gradual. Initially, monetary policy tools were non-existent.
After the establishment of NRB in 1956 (2013 BS), early efforts focused on currency issuance, banking system support, and exchange rate stability.

• Nepal created basic institutions like Nepal Industrial Development Corporation, Rastriya Banijya Bank, and Agricultural Development Bank.

• But formal liquidity management, through instruments like CRR (Cash Reserve Ratio) or Open Market Operations (OMO), only started in 2023 BS (1966 AD).

• Later, statutory liquidity requirements were introduced in 2031 BS (1974 AD) to enforce banks' investment in government securities.

By the 1990s:

• Globalization and liberalization pressured Nepal to make its financial sector more competitive.

• Fixed interest rates (set by NRB) were abandoned in 2043 BS (1986 AD) — banks gained freedom to set their own deposit and loan rates.

• Treasury Bill auctions started in 2045 BS (1988 AD), moving towards a market-based government debt market.

Despite all these reforms, Nepal's short-term interbank rates remained highly volatile because:

• Liquidity forecasting was weak,

• Monetary transmission was inefficient,

• Open market operations were underdeveloped.

The Problem:

Without stable short-term interest rates, monetary policy couldn't effectively manage inflation, credit, or economic growth.

What is the Interest Rate Corridor (IRC)?

The IRC is a monetary policy framework designed to keep short-term market interest rates (especially interbank rates) within a pre-defined band.

• Upper Bound: The rate at which banks can borrow from the central bank (Standing Lending Facility Rate - SLF).

• Lower Bound: The rate at which banks can deposit surplus funds with the central bank (Standing Deposit Facility Rate - SDF).

• Policy Rate: A midpoint target (in Nepal’s case, the 14-day Repo Rate) that monetary operations aim to maintain.

By doing so, NRB seeks to stabilize:

• Market liquidity,

• Lending and deposit rates,

• Inflation and economic growth.

The IRC model has been globally adopted — Canada (1999), European Central Bank (1999), USA (2008), Pakistan (2009), Turkey (2010), India (2011), among others.

Nepal’s Progress: How IRC Was Rolled Out

Current Setup (as of FY 2080/81):

• Upper Limit (SLF Rate): 6.5%

• Lower Limit (SDF Rate): 3.0%

• Policy Rate (14-day Repo Rate): 5.0%

Impact: Improvements after Full IRC Implementation

Before February 2024 (Fagun 2080):

• Interbank rates often dropped below the intended lower bound (3%) during liquidity surplus periods.

• Lack of a permanent deposit facility meant NRB couldn’t fully absorb excess liquidity.

• Sharp fluctuations in interbank rates (from 0.2% to 8.5%) were observed.

After February 2024:

• With the standing deposit facility operational, interbank rates have stabilized at or above 3%.

• Monetary policy signals have become more predictable.

• Open market operations (Repo, Reverse Repo) have become more active.

• Liquidity forecasting and cash management have improved.

Interpretation:
Nepal has finally built a full modern monetary operating framework. But real success now depends on how strictly and smartly it is maintained.

Challenges Remaining

Despite strong progress, several cracks are visible:

1. Partial Availability of SDF

   • Standing Deposit Facility (lower bound protection) is offered only three days a week.

   • On other days, interbank rates can still fall below 3%.

2. Wide Corridor

   • Current 3.5% spread between lower and upper bounds is still too wide.

   • Globally, effective corridors are usually 0.5%-1% wide.

3. Overlapping Liquidity Windows

   • NRB offers overnight liquidity at policy rate and SLF at upper limit — confusing banks and weakening corridor control.

4. Dependence on NRB

   • If corridor too narrow, banks run to NRB instead of lending among themselves.

   • If too wide, interbank rates swing too much.

5. Weak Transparency in Interbank Market

   • No full real-time reporting of interbank transactions (like India’s TMS system).

   • Interest rate discovery is still opaque.

6. Informal and Semi-Formal Financial Sector

   • Shadow banking practices affect deposit and loan rates unpredictably.

   • Limits effectiveness of formal monetary policy.

Recommendations for Improvement

NRB’s analysis recommends:

• Narrow the Corridor:
  Gradually shrink the spread to around 1%. Example: 5% - 6%.

• Reform Liquidity Windows:
  Offer all liquidity at a single rate (either eliminate overnight window or merge it with SLF).

• Make SDF Daily:
  Allow permanent deposit facility availability every business day, not just 3 days.

• Dynamic CRR:
  Revise Cash Reserve Ratio to be dynamic — tied to deposit growth rates, not fixed percentages.

• Interbank Market Modernization:
  Use real-time trading and reporting platforms for interbank lending.

• Curb Informal Finance:
  Strengthen regulation and incentives to push informal transactions into the formal banking system.

A Historic Step Forward, But Vigilance Needed

Nepal’s adoption of a full-fledged Interest Rate Corridor brings its monetary policy execution closer to global standards.
However, the IRC is only a tool, not an end goal.
Without ongoing fine-tuning, close monitoring, and policy discipline, the expected benefits — stable interest rates, efficient liquidity management, and effective inflation targeting — may not materialize.

If NRB aggressively continues reforms — narrowing the corridor, deepening the interbank market, and containing informal finance — then Nepal’s financial system could finally match the stability and efficiency of more mature economies.
