As a student of economics, I am interested in how macroeconomic frameworks illuminate complex economic outcomes. The so-called liquidity paradox is one such case: despite abundant deposits in the banking system, real economic activity may remain subdued.
At first glance, this appears to be a financial anomaly. Yet persistent excess liquidity is rarely a standalone phenomenon. Rather, it reflects deeper structural and sectoral imbalances within the economy. While temporary liquidity fluctuations are common in business cycles, repeated episodes of surplus funds alongside weak investment suggest a sustained gap between savings and productive capital formation.
Understanding this dynamic requires moving beyond institutional or policy-specific explanations and returning to the fundamental national income identity that governs the financial balances of households, firms, the government, and the external sector.
The Unavoidable Identity
`S - I = \text{Current Account Balance}`
In macroeconomics, the "Liquidity Paradox" is explained by a simple equation:
`(S - I) + (T - G) = (R+ X - M)`
`(S - I)`: Private Savings minus Private Investment.
`(T - G)`: Government Tax Revenue minus Spending (Fiscal Balance).
`(R+X - M)`: Exports/Remittances minus Imports (Current Account Balance).
In Nepal today, this equation is heavily lopsided. Savings (`S`) are at an all-time high due to record-breaking remittances. Meanwhile, Investment (`I`) is shrinking because businesses are hesitant to expand. When the private sector saves more than it invests, that money flows into bank vaults.
Unless the government spends its budget (`G`) or the country starts importing capital goods (`M`), that money stays "trapped" as excess liquidity. The NRB manages the flow, but it doesn't create the structural dam holding the water back.
Breaking Down the Sectoral Imbalances
The reason we shouldn't "blame" the central bank alone is that liquidity is being forced into the system by three other powerful sectors:
The government often collects revenue efficiently but struggles to spend its development budget. When capital expenditure is delayed, the "multiplier effect" vanishes. Without government-led infrastructure projects, the private sector (cement, steel, construction) has no incentive to take out new loans.
Even with interest rates at multi-year lows, credit demand is stagnant. Why? Because businesses are facing high operational costs and low consumer demand. When entrepreneurs choose to "wait and see" rather than build factories, the `S - I` gap widens. Monetary easing can reduce the cost of borrowing, but it cannot directly improve expected profitability. Share of private investment in GDP has declined to about 14 percent in 2025 compared to about 22 percent in 2021. This shortfall in private investment is the direct contributor of today's excess liquidity.
3. The External Sector: The Remittance Mirage (`R+ X - M`)
Nepal’s strong remittance inflows have supported a current account surplus and boosted domestic deposits. When foreign exchange earnings are converted into domestic currency, liquidity expands. If these inflows are not matched by increased imports of capital goods or higher productive investment, surplus liquidity accumulates within the banking system.
Yet external strength also provides macroeconomic stability. Adequate reserves enhance confidence and reduce vulnerability to external shocks. The challenge is not the inflow itself, but limited domestic absorption capacity.
4. The Household Sector: Precautionary Savings
Amidst economic uncertainty, families are choosing to save rather than spend. This high level of "precautionary savings" further boosts bank deposits, contributing to the glut of loanable funds that no one is currently willing to borrow.
Reserve Adequacy: The "Golden Cage"
Foreign exchange reserves are currently enough to cover over 18 months of imports. While this provides security, it is also a mirror of domestic inactivity. High reserves occur because the country is not spending foreign earnings.
The Way Forward: A Multi-Sector Solution
A balanced approach is necessary. Excess liquidity cannot be solved by monetary tightening alone, nor should it be viewed as a technical failure of liquidity management. When savings persistently exceed investment, the solution must address the deeper structural drivers behind that imbalance.
In Nepal’s case, this requires coordinated reform across investment climate, fiscal execution, financial markets, institutional quality, and external management.
1. Improve the Investment Climate: From Saving to Investing
Nepal’s excess liquidity reflects cautious private behavior in an environment where regulatory uncertainty, slow contract enforcement, and weak property rights raise the perceived risk of long-term investment. Interest rates alone cannot overcome these structural constraints. Strengthening rule of law, ensuring consistent and transparent regulatory enforcement, improving dispute resolution, and securing collateral and land titling systems would reduce risk premiums and encourage firms to shift from defensive saving toward productive investment — the most organic way to absorb surplus liquidity.
2. Enhance Fiscal Effectiveness: Capital Expenditure as a Catalyst
Liquidity often accumulates when budgeted public spending, especially capital expenditure, is under-executed due to procurement delays and administrative bottlenecks. Front-loading high-quality infrastructure investment can stimulate private-sector borrowing, crowd in complementary investment, and strengthen aggregate demand. The solution is not simply larger deficits, but better execution — prioritizing productivity-enhancing sectors and improving public financial management so that fiscal policy supports structural transformation rather than short-term consumption.
3. Deepen Financial Markets: Channel Savings into Long-Term Capital
A bank-dominated financial system concentrates savings in short-term deposits, limiting their productive use. Developing government and corporate bond markets, strengthening pension and insurance funds, and expanding long-term financing instruments would create alternative channels to absorb excess deposits. Financial deepening transforms idle liquidity into infrastructure and industrial investment, reducing repeated reliance on central bank absorption tools and strengthening capital allocation efficiency.
4. Strengthen Institutions, Rule of Law, and Governance
Persistent liquidity surplus ultimately signals limited confidence in long-term economic prospects. Strong institutions — credible courts, transparent regulators, enforceable bankruptcy laws, and secure property rights — create predictability and reduce uncertainty. Strict but impartial enforcement of laws ensures that investment decisions are based on market fundamentals rather than discretionary practices, gradually shifting the economy from precautionary savings toward sustained capital formation.
5. Strengthen External Management: From Sterilization to Strategic Utilization
While sterilization operations can manage short-term liquidity pressures arising from remittance and foreign exchange inflows, they do not resolve structural imbalances between savings and investment. A strategic approach would use external strength to enhance domestic productivity — facilitating capital goods imports, encouraging technology adoption, and channeling remittances into investment vehicles. By expanding the economy’s absorption capacity, external inflows can become a driver of growth rather than a recurring source of excess liquidity.
Conclusion
Liquidity can be understood as a reflection of an economy’s capacity to transform savings into productive capital formation. It indicates how effectively remittance inflows and domestic deposits are intermediated into investment in agriculture, industry, infrastructure, and technology. Persistent excess liquidity, therefore, may signal not merely a technical imbalance in money markets but a deeper shortfall in investment absorption and confidence. When legal protections are credible and institutional incentives align with productive risk-taking, financial resources are more likely to flow toward long-term capital formation rather than remain concentrated in low-risk assets.
Attributing prolonged liquidity mismatches solely to monetary management overlooks the broader macroeconomic structure within which policy operates. The Nepal Rastra Bank can influence liquidity conditions and interest rates, but it cannot independently generate sustainable credit demand. Nepal’s recurring episodes of surplus and tight liquidity reflect underlying sectoral imbalances between savings and investment, fiscal plans and execution, and external inflows and domestic absorption capacity. Weak coordination across macroeconomic policies, elevated business uncertainty, and institutional constraints further shape these outcomes. In environments where contract enforcement and bankruptcy resolution mechanisms remain limited, banks may rationally prefer collateral-based lending, which constrains financing for innovation-driven or intangible-capital-intensive ventures.
The policy implication is not a single corrective measure, but institutional strengthening and coordinated reform. A predictable legal framework, improved governance quality, and well-designed investment incentives would gradually reduce perceived risk and encourage productive borrowing. As confidence and institutional credibility deepen, surplus liquidity can be intermediated more effectively into enterprises that expand productive capacity. In such a setting, liquidity would no longer appear paradoxical; rather, it would function as a catalyst for sustainable and broad-based economic growth.
