I. Introduction

Picture this: a farmer in Maharashtra stares helplessly at his parched land; a textile worker in Bangladesh wades through floodwater to salvage her only source of income; a middle manager in Chennai finds her insurance premiums soaring after yet another cyclone; and somewhere in Wall Street, a portfolio manager frantically recalibrates her climate-risk exposure algorithm. This isn’t dystopian fiction. It’s your Tuesday morning, courtesy of climate change.

We are beyond debating whether climate change is real; we’re grappling with how violently it is rewiring the rules of economics, society, and survival itself. What was once a slow-moving environmental concern now comes with a side of market volatility, inflation spikes, systemic credit risks, insurance black holes, and a long-overdue realisation: climate change is the new financial pandemic, only this one doesn’t flatten curves; it also flattens livelihoods. And within this chaos, a chilling pattern emerges: women, particularly in the Global South, suffer the most. Climate change is not just an ecological crisis; it’s also a threat multiplier, a poverty accelerator, and a deeply gendered disaster.

II. Climate change and the global financial ecosystem

A. Systemic risks and economic disruption

1. Extreme weather is the new market regulator: Climate events like floods, cyclones, and wildfires are increasingly becoming economic events. From Hurricane Sandy crippling the US East Coast to Assam’s annual monsoon floods, climate events are rewriting risk models. The financial cost of these disasters is staggering.

These disruptions devastate infrastructure, halt supply chains, and force market volatility. Mumbai’s recurring floods not only damage physical assets but also reduce business days and strain city resources.

The financial repercussions ripple through real estate values, insurance claims, and urban lending practices. Assam’s floods alone have caused billions in asset damage, prompting banks to rethink asset concentration in such zones. Gone are the days when markets were disrupted by interest rate changes or oil shocks.

Today, it’s cyclones, floods, and wildfires that are calling the shots. Supply chains are no longer just ‘global’; they're globally fragile. One freak weather event in one corner of the world can send prices soaring in another.

2. Droughts, crop failures, and agricultural finance in turmoil: Erratic rainfall and prolonged dry spells are wreaking havoc on India’s agricultural backbone. Farmers in Maharashtra and Karnataka have seen dramatic drops in productivity, leading to mass loan defaults and the erosion of local banking stability. Microfinance institutions that rely on high repayment rates suffer as climate unpredictability breaks traditional agrarian cycles. With rainfall patterns growing erratic, Indian agriculture is at a tipping point.

When rainfall patterns become unpredictable, so do crop yields and so does the income of many Indian farmers. This has a knock-on effect on microfinance institutions and cooperative banks. Now imagine the perspective of a bank manager in a rural branch. Every year, you're expected to lend under priority sector norms, but repayment becomes a game of Russian roulette thanks to climate uncertainties. The farmer is now a high-risk borrower, and the entire agricultural loan portfolio is wobbling.

3. Insurance markets in crisis: The traditional insurance model is crumbling under the weight of climate variability. As premiums rise and coverage becomes restrictive, insurance becomes inaccessible to the very groups that need it most. Government schemes like PMFBY are marred by exclusionary criteria, delays in settlement, and low awareness, particularly among women farmers who often lack formal land ownership or identification.
