As we celebrate Dussehra, the victory of Rama over Ravana, the Ramayana is worth rereading as a story about geography before it is a story about war. Lanka was not won by courage alone. It lay across the sea, an island fortress that no army on foot could march into. Rama's vanar sena could assemble, supply, and motivate itself, yet every plan for the campaign ended at the same obstacle: a vast stretch of ocean. The epic's answer was an act of engineering, the bridge raised across the waters, and its lesson was strategic. Before the battle could be fought, the route had to be solved.

 

Three thousand years of storytelling later, little has changed. The great contests of our age are still decided by who controls the narrow passage, the sea lane and the crossing point. Our armies are now tankers, our supplies are crude and gas, and our Lanka is whichever economy depends on a strait it does not command. Nothing much has changed except that the ocean now appears on the balance sheet.

 

I went into Tim Marshall's Prisoners of Geography expecting borders, mountains and military strategy. I came out thinking about oil invoices, freight rates, the rupee and the assumptions buried inside an investor's spreadsheet.

 

How much of what we call investment risk is simply geography in disguise? We call it an oil shock when crude becomes expensive, currency volatility when the rupee weakens, supply-chain disruption when a factory cannot get an input, and inflation when the household finally feels it. Often the cause is older than the headline: a country's dependence on a single sea route, a firm's reliance on a single distant supplier. This economy cannot produce enough of what it consumes.

 

Geography is not a headline. It is the condition beneath the headline. The map has not changed. Our attention to it has.

 

A strait that reaches your portfolio

 

2026 has made the argument tangible. Disruption around the Strait of Hormuz has turned a strategic vulnerability into a global energy and financial shock. Reuters reported that ship and mine incidents helped push crude towards $110 a barrel on Friday, 16 October, with Brent around $108 on Monday, 19 October. The price will keep moving. The mechanism will not: when a critical route is threatened, markets reprice energy's cost and availability at once.

 

So the useful question is not "where will oil trade next?" It is what expensive, uncertain energy does to inflation, currencies, interest rates, margins and the value of assets.

 

The shock is unevenly distributed. Exporters may enjoy a windfall; import-dependent economies pay the bill. Within one economy, an oil producer's higher realisation is an airline's higher cost and a paint maker's squeezed margins. A company with pricing power may pass the shock on. A leveraged business with thin margins may find itself facing a balance-sheet problem. The same event is a windfall for one portfolio holding and a strain for another.

 

Forecasting the next escalation or ceasefire is hard. Mapping a portfolio's exposure to either is far more achievable.

 

India: the oil shock travels through the rupee

 

India's geography gives it a large, connected domestic market and a long coastline for trade. It also gives it two structural dependencies: imported crude and the monsoon.

 

The first is already visible in the numbers. The Indian Express reported that India's net oil and gas import bill reached $57.8 billion in April–July 2026, up 43.4% from $40.3 billion a year earlier. Reuters reported on 19 October that the rupee was near ₹94.93 to the dollar, weighed down by importer demand. The RBI has moved to manage oil companies' dollar demand, and its October policy included a rate increase, the first in four years.

 

These are links in one chain: geopolitical risk, expensive energy, external payment pressure, a weaker rupee, inflation risk, and tighter financial conditions. A weaker rupee raises the rupee cost of the very energy that caused it.

 

The second dependence is quieter. A deficient monsoon is not only a weather event. It runs through farm output, rural incomes, food prices, and demand for two-wheelers, tractors, fertiliser, and consumer goods, narrowing the room for monetary policy. An energy shock arriving on top of a weak monsoon would compound rather than add.

 

None of this means India's growth story ends when oil rises. It means the path of growth, inflation and earnings becomes more conditional, and investors should ask which companies are adapting and which are hoping the next disruption does not arrive.

 

The Russia–Ukraine war shows the same logic from another angle. Refineries, export routes and sanctions regimes are instruments of strategy. The reported US–Russia diesel arrangement may shift flows. Still, it does not remove the risk to infrastructure, and a policy announcement is not the same as reliable supply. Portfolios that treat such constraints as temporary interruptions may underestimate how long they last.

 

The second-round effect, and why resilience has a price

 

The most consequential market effect of an energy shock may not be the first move in crude. It may be the second round. If energy feeds into broader inflation, central banks lose room to ease. Bond yields and borrowing costs rise, and equity valuations, which depend on the discount rate, fall. The uncomfortable combination is costs rising at the same moment the multiple investors will pay is shrinking. Credit investors face a parallel test: can a business service debt when operating costs, working capital and refinancing rates all climb?

 

Currency adds another layer. A weaker rupee helps some exporters, but raises the cost of imported inputs and foreign-currency liabilities. The net effect depends on revenue mix, sourcing, hedging and debt structure, not on whether a company carries the label "exporter." Nor are the winners simply "energy stocks." Higher crude helps producers only after taxes, regulation and costs, and only if the price lasts. Energy security may accelerate the adoption of renewables, storage, and domestic infrastructure, which are durable themes. Still, a compelling need is not a compelling valuation.

 

This is why resilience deserves to be treated as a financial characteristic. For years, markets rewarded efficiency: lean inventories, concentrated sourcing, the cheapest route. Multiple suppliers, inventory buffers, hedges, and strategic reserves can look wasteful during calm periods. Their value appears when normal routes fail. Resilience has a cost, and excessive redundancy destroys value. The test is whether the cost of protection is proportionate to the loss it prevents. In other words, evaluate it like any other capital-allocation decision.

 

Five questions before the model

 

I would add these to the usual review of valuation, balance sheet, and earnings quality, for a company or a country:

1. Where is the physical bottleneck? Identify the routes, ports, suppliers, or inputs the business depends on, and the points at which it could break.
2. What if disruption lasts six months, not six weeks? Stress-test margins, inventory, working capital, and debt-servicing capacity.
3. Who absorbs the higher cost? Pricing power matters most when costs are volatile.
4. What if inflation keeps rates higher for longer? Revisit refinancing needs and the valuation assumptions that rest on a lower discount rate.
5. Is the vulnerability changing, and is the market already pricing it? Alternative suppliers, domestic production, and better logistics can reduce exposure. A structurally exposed company may be attractively priced, or its discount may be entirely deserved.

 

Geography is a discipline, not a forecast.

 

One qualification. Geography explains constraints, not everything. Institutions, technology, capital allocation and human ingenuity can change what a physical location costs a country, and a favorable location does not make an asset cheap. The map tells us how durable an advantage or vulnerability is. Valuation tells us what we are paying for it. Before asking whether a business has a strong balance sheet, ask whether it can obtain the inputs it needs. Before assuming growth will continue, ask what could interrupt it. Before treating a distant event as distant, trace its route into energy prices, the currency, the cost of capital, and finally the portfolio.

 

My dear readers, The next shock may arrive as an oil spike, a shipping disruption or a currency move. Its form may surprise us. Its geography usually will not.

Read the map before you read the model.
