When Aristotle observed that "the whole is greater than the sum of its parts," he could hardly have imagined his words being applied to central banking in a small island nation navigating one of its worst economic crises in modern history. Yet the sentiment captures precisely what Sri Lanka's policymakers must internalize as the country works to rebuild its foreign exchange reserves — a task that demands wisdom, balance, and a long-term strategic vision rather than a desperate, cost-blind accumulation of dollars.
The Governor of the Central Bank of Sri Lanka, Dr. Nandalal Weerasinghe, has drawn well-deserved recognition for framing the reserve-building conversation within its proper broader context. Speaking at the Reserve Management Conference, Dr. Weerasinghe made clear that foreign reserves cannot and should not be built sustainably at any cost. It is a statement that sounds simple but carries profound implications for Sri Lanka's economic recovery trajectory.
Why Foreign Reserves Matter — But Are Not Everything
Foreign exchange reserves serve as a critical buffer for any nation. They provide the capacity to meet import obligations, service external debt, defend the national currency during periods of volatility, and signal creditworthiness to international investors and lenders. For Sri Lanka, which experienced a catastrophic reserve depletion leading to its 2022 sovereign default — the first in the country's post-independence history — rebuilding reserves has become a national economic priority.
However, the manner in which reserves are accumulated matters enormously. A country that builds reserves by suppressing domestic consumption, imposing harsh austerity measures that devastate ordinary citizens, or borrowing at punishing interest rates may achieve a healthier-looking balance sheet in the short term while sowing the seeds of deeper instability in the long run. Reserve accumulation pursued recklessly can undermine the very economic foundations it is meant to protect.
The Hidden Costs of Building Reserves at Any Price
Prof. Asoka S. Seneviratne's analysis highlights a critical tension that policymakers must navigate carefully. On one side sits the urgent need to restore reserve adequacy and regain access to international capital markets. On the other side lies the equally urgent need to restore economic growth, protect vulnerable populations, and maintain social and political stability.
When reserve-building strategies lean too heavily on contractionary monetary policy — keeping interest rates excessively high for prolonged periods — the collateral damage can be severe. Businesses struggle to access affordable credit. Investment dries up. Unemployment rises. Consumer spending contracts. The economy, already weakened by crisis, risks falling into a prolonged stagnation that ultimately makes reserve sustainability even harder to achieve.
Similarly, if reserve accumulation relies disproportionately on remittance inflows captured through aggressive exchange rate management, it may create distortions that discourage formal financial flows over time. Short-term reserve gains can mask medium-term structural vulnerabilities.
A Smarter Approach to Reserve Management
What does building reserves wisely actually look like in practice? Experts point to several interconnected principles that Sri Lanka's policymakers would do well to embrace fully.
First, reserve accumulation must be tied to genuine export growth and foreign direct investment attraction rather than relying primarily on debt inflows or temporary capital account measures. Sustainable reserves are earned through a competitive, productive economy — not borrowed into existence.
Second, monetary policy must be calibrated carefully to balance reserve objectives against growth imperatives. Central banks operating in post-crisis environments face the difficult challenge of maintaining credibility and currency stability without strangling economic recovery. This requires nuanced, data-driven decision-making rather than rigid adherence to a single policy target.
Third, fiscal discipline must complement monetary strategy. Sri Lanka's reserve crisis was not simply a monetary phenomenon — it was deeply rooted in chronic fiscal deficits, unsustainable debt accumulation, and governance failures that eroded economic resilience over decades. Rebuilding reserves without addressing these structural weaknesses would be building on sand.
The Broader Economic Vision Cannot Be Forgotten
Dr. Weerasinghe's framing reflects a sophisticated understanding that central banking does not operate in isolation. The health of a nation's foreign reserves is ultimately a reflection of the health of its broader economy — its productivity, its competitiveness, its institutional quality, and its social cohesion. A reserve buffer built atop a struggling, inequitable economy is far more fragile than a modest reserve cushion supported by robust, inclusive growth.
Sri Lanka stands at a genuine crossroads. The progress made since the darkest days of 2022 is real and should not be minimized. Reserves have recovered from critically low levels. The currency has stabilized. Inflation has been brought under control. The IMF program has provided a credible anchor for reform.
But the work ahead remains substantial. Policymakers must resist the temptation to declare victory prematurely or to pursue reserve targets in ways that sacrifice the long-term productive capacity of the economy. As Aristotle understood intuitively, the goal is systemic health — not the optimization of any single indicator at the expense of the whole.
Sri Lanka's reserves must be built wisely, strategically, and sustainably. Anything less would be a costly mistake the country cannot afford to make twice.
