Spain ranks 16th out of the 88 countries analysed in the 2026 edition of the Global Real Estate Transparency Index (GRETI), compiled by JLL and LaSalle Research and published on 15 October. The country has moved up two places since the previous edition and remains in the “Transparent” category.
The index assesses real estate transparency using quantitative data and information gathered by JLL and LaSalle teams across 88 countries and 146 urban markets. The scale runs from 1, full transparency, to 5, full opacity. With a score of 2.01, Spain is ahead of markets such as Dubai, Switzerland, Poland and Italy. Markets classified as “Transparent” and “Highly Transparent” account for more than 98% of global real estate capital, reflecting the link between transparency, market depth and the ability to attract investment.
The report also identifies trends that are changing the sector’s information needs, including the growth of alternative real estate assets, the energy transition, more diverse sources of financing, the rise of artificial intelligence and regulatory change.
Investment in alternative segments accounts for around 20% of global real estate volumes, roughly double the share of a decade ago, although the report notes that information is still limited in some of these sectors. Global investment linked to the energy transition reached $2.3 trillion in 2025.
In financing, banks, insurers, debt funds and private credit providers are broadening the base of real estate lenders and helping to improve the information available. However, the market remains fragmented and lacks a centralised database.
More than 90% of investors and occupiers surveyed use AI-based tools. At the same time, cybersecurity and uncertainty over AI’s impact on future demand for space are among the medium-term risks for real estate portfolios. The report also suggests that some regulatory changes could open the market to new types of investors and lead to more than $800 billion in new allocations to real estate by 2030.
