The question of whether Nepal’s monetary policy is independent has long been debated among academics, policymakers, and market participants. Nepal has maintained a fixed exchange rate with the Indian rupee for about three decades, leading many to argue that the Nepal Rastra Bank (NRB) has little or no control over domestic monetary conditions. In my view, Nepal’s monetary policy is independent, but within limits.
The starting point for understanding this issue is the Mundell–Fleming trilemma, or the “impossible trinity.” The framework states that a country cannot simultaneously maintain a fixed exchange rate, full capital mobility, and an independent monetary policy. A country can choose only two of these three objectives. Nepal’s monetary policy framework reflects one such combination. It maintains a fixed exchange rate with the Indian rupee while imposing significant restrictions on cross-border capital movements. Because capital mobility is limited, the NRB retains a meaningful degree of monetary policy autonomy despite the exchange rate peg.
Empirical evidence also supports this interpretation. Bhatta et al. (2022) find little evidence that uncovered interest parity (UIP) holds in Nepal. In other words, domestic interest rates do not automatically converge to India's interest rates. Consequently, the NRB retains discretion to influence domestic liquidity conditions through its monetary policy instruments, including short-term interest rates and liquidity management operations.
This autonomy, however, should not be viewed as absolute. Nepal’s current account is largely open, and cross-border trade, remittances, tourism, and informal financial channels create de facto capital movements that are not always captured by formal regulations. Such leakages can weaken the effectiveness of domestic monetary policy and make maintaining the exchange rate peg more challenging. Therefore, it is more accurate to describe Nepal as having limited, rather than complete, monetary policy independence.
Another issue that frequently creates confusion is the distinction between financial openness and financial integration. Although the two concepts are related, they are not synonymous. Financial openness refers to the legal and regulatory framework governing cross-border capital movements. Nepal continues to maintain significant restrictions on portfolio investment and many other forms of short-term capital flows, indicating a relatively closed capital account. Financial integration, by contrast, refers to the extent to which an economy is connected with the rest of the world through trade, investment, remittances, banking relationships, and other financial linkages. Nepal is deeply integrated with India through trade, labor migration, remittances, tourism, and foreign direct investment, despite maintaining restrictions on many forms of capital mobility. Thus, a country may be highly integrated with another economy while remaining only partially financially open.
Nepal's long-standing fixed exchange rate with Indian currency has also attracted attention. The rationale extends beyond exchange rate stability. India is Nepal’s largest trading partner, accounting for the overwhelming share of Nepal’s merchandise trade. A stable bilateral exchange rate reduces transaction costs, minimizes exchange rate uncertainty, and facilitates cross-border trade and investment. Nepal and India also share an open border, extensive labor mobility, tourism, and remittance flows. Because the two economies are closely linked and often experience similar regional economic shocks, the costs of maintaining a fixed exchange rate are comparatively lower than they would be for economies with less integrated trading relationships.
The exchange rate peg also contributes to macroeconomic stability by serving as a credible nominal anchor (see Mundell's Optimal Currency Area). For a small open economy that imports a substantial share of its consumption and intermediate goods from India, exchange rate stability helps contain imported inflation and anchor inflation expectations. This is particularly important when the exchange rate pass-through to domestic prices is significant.
Beyond these economic considerations, the peg also serves an important institutional purpose. The monetary economics literature has long emphasized that discretionary monetary policy may suffer from the time inconsistency problem. Kydland and Prescott (1977) demonstrated that policymakers may announce a low-inflation policy but later have incentives to pursue expansionary monetary policy to stimulate output or employment in the short run. Recognizing these incentives, economic agents adjust their expectations, leading to higher inflation without a permanent increase in output. Barro and Gordon (1983) formalized this argument by showing that discretionary monetary policy creates an inflationary bias because rational agents anticipate policymakers’ incentives.
A credible commitment mechanism can mitigate this problem. For many small open economies, a fixed exchange rate provides such a mechanism by tying domestic monetary policy to a stable external nominal anchor. In Nepal’s case, the peg to the Indian rupee strengthens policy credibility by constraining discretionary monetary expansion, anchoring inflation expectations, and reinforcing confidence in the monetary framework. While the peg does not eliminate the need for prudent domestic policymaking, it helps reduce inflationary bias and supports the broader objectives of price stability and external sector stability.
This does not imply that Nepal has surrendered monetary policy altogether. Rather, the exchange rate peg and capital controls together define the scope within which monetary policy operates. The NRB retains discretion over domestic liquidity management and short-term monetary operations, but these decisions must remain consistent with the objectives of preserving exchange rate stability and maintaining adequate foreign exchange reserves. Nepal’s monetary policy framework represents a pragmatic balance between credibility, stability, and domestic policy flexibility. The exchange rate peg provides a credible nominal anchor and supports macroeconomic stability, while capital controls preserve a meaningful, though necessarily limited, degree of monetary policy independence.
