The Part I of this series argued that while currency intervention can temporarily moderate disorderly foreign exchange movements, it cannot correct the structural conditions that leave the rupee vulnerable to external pressure. The next question is how policymakers can assess whether growth choices are reducing India’s exposure to external shocks. Exchange rates, current account balances and reserves remain essential indicators, but they do not fully reveal whether economic expansion is strengthening the capacity to meet future external payments.

This relationship may be described as the ‘growth productivity of foreign exchange’. It is neither a standard statistical measure nor a call to minimise imports. Rather, it is a framework for assessing whether incremental economic activity expands future capacity to earn or conserve foreign exchange, and whether those returns justify the external claims created along the way.

A practical assessment can be organised around three connected dimensions: exposure, earning capacity, and shock absorption and adjustment.

Measuring Resilience
Exposure concerns the foreign exchange required to sustain production and investment. Beyond headline import values, policymakers need to identify where external requirements are concentrated, how quickly they can change and whether firms have realistic alternatives when supply or financing is disrupted. Sector-level mapping can reveal dependencies concealed by aggregate trade figures. A small imported component, for instance, may constrain an entire production chain, while a broad import category may contain readily substitutable inputs. The objective is to identify bottlenecks and estimate the economic consequences of disruption than label all imports as risks.

Earning capacity asks whether foreign exchange receipts are durable, diversified and resilient to changes in demand or market access. The analysis should distinguish recurring contractual receipts from volatile or concentrated earnings and assess dependence on a narrow set of customers, destinations, firms or activities.

Services exports and remittances remain important strengths, but concentration can expose receipts to common shocks. Policymakers, therefore, need to understand how widely earning capacity is distributed and how readily it can adapt when one source weakens.

Shock absorption and adjustment examine what happens when pressures arrive.  Reserves provide time, but resilience also depends on how quickly firms can hedge, refinance, switch suppliers, redirect exports or reduce non-essential foreign exchange outlays. Relevant indicators include the maturity and currency composition of external liabilities, access to hedging, market liquidity, contractual payment schedules and the time needed to restore disrupted supply or receipts. The central question is how much time the available buffers buy and whether stakeholders can use it effectively.

These dimensions could form an External Economic Resilience Dashboard, which, instead of duplicating the  existing balance-of-payments statistics or assessments, would integrate established capabilities to assess external exposures, the quality of foreign exchange receipts and the capacity to absorb and adjust to shocks.

Indicators could include critical-input concentration, substitutability, export-receipt concentration, external payment schedules, liability maturities and hedging availability.

Results should be disaggregated by sector rather than collapsed into a single score, which could conceal trade-offs, dependencies and vulnerabilities that emerge only under particular conditions.

To make the dashboard operational, it would need clear ownership, common definitions and a regular review cycle. Data gaps should be recorded than be obscured by estimates, while indicators should distinguish observed exposures from contingent risks. Findings should inform contingency planning, including thresholds for intensified monitoring and pre-agreed coordination among relevant agencies. Reviews should track material changes, not merely compliance with thresholds, and document scenario assumptions to ensure comparability over time. This would strengthen the evidence base within existing institutional mandates without requiring an additional layer of exchange-rate management.

The dashboard should also support integrated external-sector stress tests. Policymakers could model scenarios in which energy prices rise as export demand weakens, portfolio investment reverses and external borrowing costs increase. These exercises should trace how the initial shock travels through sectors, firms and financial institutions, estimate the timing and scale of resulting foreign exchange needs, and distinguish temporary liquidity shortfalls from persistent financing gaps. They should also identify which adjustment channels remain available and which could fail simultaneously. The objective is preparedness, not prediction.

Investment appraisal could use the same framework without turning it into a rigid entry test or a blanket import-substitution target. One further consideration is the interval between an investment’s foreign exchange requirements and its capacity to generate returns. Even economically viable projects can intensify external pressure when substantial payments fall due well before earnings materialise. Recognising this temporal gap would add a useful dimension to appraisal: not simply whether an activity creates value, but whether the external economy can sustain the path to its eventual returns.

From Defence to Resilience
The framework also changes how success should be judged. A weaker rupee does not necessarily signal policy failure, just as nominal stability does not prove that competitiveness is improving. A wider current account deficit may reflect productive investment, while a comfortable aggregate position can conceal concentrated exposures or repayment pressures. Assessment must therefore combine the direction of conventional indicators with evidence of the economy’s ability to absorb shocks and adjust without disruptive cuts in activity or repeated emergency financing.

India needs neither a permanently appreciating currency nor insulation from global markets. It needs growth that broadens durable foreign exchange earning capacity, exposes vulnerabilities before they become acute and gives firms and policymakers time to respond when shocks arrive.

The test of resilience is not whether the rupee can be defended at every moment, but whether India’s economy becomes less vulnerable to the forces that repeatedly make that defence necessary.
