Mumbai’s Office Market Gains Momentum

Mumbai’s commercial real-estate market witnessed robust growth in the first half of 2026, with gross office leasing rising 33% year-on-year to 7.3 million sq ft, according to a report by Knight Frank India. The strong performance places the city among the country’s leading office destinations, driven by rising demand from global capability centres (GCCs), BFSI firms and third-party IT and ITeS occupiers.

The report identifies the latest leasing figures as one of Mumbai’s strongest half-yearly performances in recent years, underpinned by large institutional transactions and sustained occupier confidence. The growing presence of multinational companies and technology-driven businesses has further reinforced the city’s position as a preferred commercial hub.

Demand Outpaces Supply

While demand remained buoyant, office completions declined 30% year-on-year to 1.6 million sq ft during the period. Despite the lower supply additions, Mumbai’s total office stock expanded by 3% year-on-year to 173.8 million sq ft, reflecting the long-term strength of the market.

The tightening demand-supply equation also resulted in a notable improvement in occupancy levels. Vacancy rates fell by 205 basis points year-on-year to 15.6% in H1 2026, supported by stronger leasing activity and a slowdown in fresh supply.

Rental values, meanwhile, remained stable, with average transacted rents increasing marginally by 0.5% year-on-year to ₹130 per sq ft per month, compared with ₹125 per sq ft per month in 2025.

GCCs Drive Leasing Activity

A major driver of this growth was the increasing footprint of global capability centres, which accounted for 46% of Mumbai’s total office leasing in H1 2026, a significant jump from 11% in H1 2025.
India-facing occupiers contributed 45% of total transactions, while flexible workspace operators and third-party IT services accounted for 6% and 4%, respectively.

Among Mumbai’s business districts, SBD Central emerged as the city’s largest office market, accounting for 46% of total leasing activity, largely led by transactions in Powai. SBD West captured 20% of leasing activity, while the peripheral business district accounted for 14%.

Collectively, SBD Central, SBD West and the peripheral business district contributed nearly four-fifths of Mumbai’s total office transactions during the period. BKC and off-BKC accounted for 16% of leasing activity, followed by Central Mumbai at 9% and CBD and off-CBD at 3%.

Rental values varied across business districts. BKC and off-BKC remained the city’s most expensive office markets, recording rentals in the range of ₹237–446 per sq ft per month in H1 2026. CBD and off-CBD followed with rentals between ₹200–279 per sq ft per month, while Central Mumbai recorded rentals ranging from ₹195–279 per sq ft per month.

In comparison, SBD Central registered rentals between ₹130–232 per sq ft per month, whereas SBD West recorded rentals in the range of ₹102–195 per sq ft per month.

Mumbai’s latest leasing performance highlights the evolving dynamics of India’s commercial real-estate sector, where demand is increasingly being shaped by global corporations, technology-led enterprises and flexible workspace models. As occupiers continue to prioritise quality assets and strategic locations, the city’s office market appears poised for sustained growth despite near-term supply constraints.

Mumbai’s office market is increasingly reflecting the city’s transition from a traditional financial hub to a diversified business ecosystem driven by technology, global capability centres and flexible workspaces. As demand continues to outpace new supply in several micro-markets, the next phase of commercial growth is likely to be defined not merely by leasing volumes, but by the quality, sustainability and adaptability of office spaces. The strong performance recorded in H1 2026 also underscores Mumbai’s enduring appeal among domestic and international occupiers seeking scale, connectivity and long-term value.

Key Insights

Mumbai’s office market delivered a strong performance in the first half of 2026, with leasing activity surging amid rising demand from GCCs, BFSI companies and technology firms.

Even as office completions slowed, vacancy levels continued to decline, signalling healthy absorption across key business districts. The sharp increase in GCC participation—from 11% in H1 2025 to 46% in H1 2026—underscores Mumbai’s growing importance as a global business destination. At the same time, rental stability and expanding office stock indicate that the city’s commercial real-estate sector remains resilient and well-positioned for future growth.
