Wall street bets on shielding Indian real estate from climate disaster
Synopsis

Climate resilience is emerging as a new measure of value in India's real estate market. Investors are pouring money into infrastructure to protect rental income and asset values. This reflects a broader shift unfolding across India's significant real estate market. Capital is migrating toward buildings that can withstand a hotter, wetter climate. Climate risk now informs investment theses for many companies.

Every year during India’s monsoon season, the Mithi River swells into a brown, fast-moving force that courses through the heart of Mumbai, the country’s financial capital and second-largest city. Roads disappear under water. Cars are stranded. Entire neighborhoods almost shut down.

For years, the deluge damaged Equinox Business Park, a sprawling campus larger than seven football fields that’s built along the river’s flood plain. Basement pumps would fail, and water would seep into the grounds. Repeated flooding deterred tenants, with occupancy languishing at 16%.

Then Brookfield Asset Management Ltd. bought Equinox in 2018. The New York-based company spent $26 million raising low-lying sections of the site, strengthening flood defenses and upgrading drainage systems, according to an estimate from a person familiar with the project who was granted anonymity to discuss private financial data.

Today the corporate headquarters of India’s Leela Palaces Hotels & Resorts Ltd., an outpost of Boston-based financial giant State Street Corp. and other tenants occupy more than 99% of Equinox. Last year, Brookfield sold a 97% stake in Equinox to Singapore’s sovereign wealth fund, GIC Pte., valuing the office park at almost 40 billion rupees ($420 million). Brookfield investors more than tripled the value of their equity in the property. The flood-protection measures enabled them to reap a premium in the sale, says the person close to the deal.

This transformation reflects a broader shift unfolding across India’s $300 billion real estate market. As floods, storms and extreme rainfall become more frequent, climate resilience is emerging as a new measure of value. From the vulnerable coastlines of Mumbai and Chennai to the flood-stricken office districts of Bengaluru and Gurgaon, investors are pouring money into drainage systems, flood barriers and surrounding infrastructure to protect rental income and preserve asset values — in some cases, paying for projects such as roads that are normally the responsibility of governments.

The result is a repricing of urban India and a gradual redrawing of the country’s investment map, as capital migrates toward buildings that can withstand a hotter, wetter and more unpredictable climate. At a news conference in July, Arpit Agrawal, a Brookfield managing partner who heads its India and Middle East infrastructure group, said the company had commissioned a study to assess whether land it was considering for a data center could be prone to flooding and ended up choosing another location because of the results. “Climate risk informs our investment thesis,” said Agrawal, whose group is separate from the company’s real estate practice.

The 2005 Mumbai flood, which killed more than 1,000 people, still haunts India. It remains the country’s costliest natural disaster, resulting in $500 million in claims that year, according to reinsurer Swiss Re AG. The company estimates that a repeat could set insurers back as much as $2.3 billion and envisions that other flooding scenarios could be even worse; what’s more, over the past two decades, individual events costing $1 billion have become increasingly common. Last week, India put many of its northern states on high alert after catastrophic flash floods swept through neighboring Nepal.

Costly calamities

Like appraisals and engineering studies, formal climate-risk assessments are fast becoming fixtures in India’s commercial real estate. The country’s $7 billion National Investment and Infrastructure Fund Ltd., backed by the government and other investors, completed its first climate study last year as a way of evaluating its portfolio, which includes ports, roads and airports.

Brookfield, Blackstone Inc. and other giant investment firms increasingly use such assessments to decide whether to build, buy or expand. Singapore-based CapitaLand Investment Ltd. says it screens all investments for unacceptable climate threats. “The conversation is shifting from assessing risk to deciding where capital should go,” says Parag Khanna, founder and chief executive officer of AlphaGeo, which provides weather-based forecasting and risk analysis.

Consider the challenge of developing in Chennai. Formerly called Madras, the city on the Bay of Bengal in southern India has experienced repeated flooding from cyclones and torrential rains over the past decade. There, DLF Ltd., the largest publicly listed real estate company in India, has relocated critical electrical systems above ground level and strengthened drainage and rainwater-harvesting infrastructure, says Sriram Khattar, DLF vice chairman and managing director of its rental business. (Singapore’s GIC owns a 33% stake in DLF’s commercial leasing arm.)

Or visit Bengaluru, the center of India’s renowned tech corridor along the flood-prone Vrishabhavathi River. There, in 2020, Indian real estate conglomerate Sattva Group and Blackstone bought what is now called Global City, a massive office campus. Since then Sattva studied flood and soil patterns to identify water levels, dredged one of the river’s tributaries and removed obstructions to improve water flow. The company raised ground levels and built larger storm water tanks and higher capacity pumps to collect rainwater. The campus is now able to remain operational even during the city’s heaviest downpours. (Global City is now part of Knowledge Realty Trust, which listed in 2025 and is owned by Blackstone, Sattva and public shareholders.)

Those measures are adding 100 to 200 rupees per square foot in development costs at Global City, says Shivam Agarwal, Sattva’s vice president for strategy. That isn’t chump change for a business park the size of Global City, which will ultimately span almost half a square mile, and offers cricket, soccer, volleyball and basketball. Sattva figures it will spend 1.2 billion to 2.4 billion rupees. Tenants demand it, Agarwal says. “Flood protection has become a standard requirement for Grade A office space.”

In India’s otherwise hot property market, climate concerns are surfacing during real-estate-related initial public offerings. Blackstone, for example, owns Horizon Industrial Parks Ltd., which has properties across India and raised $272 million in an August IPO. (The investment firm still holds a 75% stake.) Horizon’s warehouses store merchandise and send out trucks to deliver products for Amazon.com Inc. and other customers that need to keep business going even during lousy weather.

In offering documents, Horizon warned investors about the potential financial impact of climate-related disruptions. Flooding from the Yamuna River in 2023 snarled freight movement across India’s busiest logistics corridor, around Delhi. In the south, cyclones and coastal flooding periodically disrupted operations at Chennai’s port and airport, and storm-related power shortages hit a nearby industrial hub.

Blackstone-backed Bagmane Prime Office REIT, which listed in May, struck a similar note, telling investors that its Bengaluru portfolio had “historically been subject to floods due to heavy rainfall, which have affected the operations of certain buildings in our portfolio assets.”

Even a few flooded buildings can set a company back by millions of dollars. Last year a climate-risk assessment, commissioned by Blackstone and conducted by insurance broker Marsh & McLennan Cos., identified two Indian properties as particularly exposed: a warehouse in the northern state of Haryana vulnerable to river flooding and a shopping mall in Chennai exposed to tropical cyclones, according to a person familiar with the findings who asked for anonymity because the results haven’t been made public. Marsh estimated that a severe cyclone could inflict about $5.25 million in physical damage on the Chennai mall. Flooding at the Haryana warehouse could cause a further $1.6 million in property damage.

Investors are increasingly weighing a question: Will owners be able to insure, finance and, ultimately, sell properties in a warming world? Some from Southeast Asia are souring on Chennai, opting to exit flood-prone cities rather than expand their exposure, says Ghulam Zia, senior executive director for real estate consultant Knight Frank in India.

Insurance bills are set to rise. Companies are incorporating flood risk into the cost and terms of their policies, as well as rewarding efforts to mitigate it, says Nisheeth Srivastava, India head of construction and infrastructure for insurance broker Aon Plc.

Signaling a potential upside for the industry, homebuyers are now willing to pay for climate protection in the same way they might appreciate an apartment with central air conditioning and a kitchen with granite countertops and professional-grade appliances.

Mumbai homes in flood-prone neighborhoods can sell for 15,000 rupees per square foot, compared with about 40,000 rupees in comparable areas without that threat, says Insha Wani, an analyst at the Climate and Sustainability Initiative, a research organization in New Delhi.

Developer Sanghvi Realty raised the foundation of one residential project in Mumbai by 6 feet, added multiple layers of waterproofing and installed pumps to keep out floodwater. This protection increased construction costs about 20%, but the company figured it would be repaid with higher sales. “We knew there would be takers if we could solve this flooding problem,” Managing Director Pakshal Sanghvi says. “We saw this as an opportunity.”
