South Korea's total ESG-related financing reached KRW 2,012.6 trillion — equivalent to approximately USD 1.5 trillion — by the end of 2024, crossing the KRW 2,000 trillion threshold for the first time since the market was established, according to data published by the Korea Sustainability Investing Forum. The milestone caps a period of sustained expansion that has more than doubled the market from its 2019 base, reflecting consistent growth across the three main product categories of ESG investments, ESG loans, and ESG bonds over five years of rapid development.
However, the headline figure masks a material deceleration in the underlying growth trajectory. Annual growth in 2024 came in at 8.9%, the first time the market has recorded a single-digit expansion rate and a sharp retreat from the 20–30% annual growth rates that characterised the years of peak ESG momentum. The slowdown invites questions about whether South Korea's ESG finance market has transitioned from a high-growth early phase into a period of maturation, or whether the deceleration reflects cyclical headwinds — including elevated interest rates and a more sceptical global ESG investment environment — that could partially reverse as conditions evolve.
INVESTMENTS DOMINATE, SUSTAINABILITY LOANS FALL
ESG investments accounted for the largest share of total financing at KRW 945.5 trillion, representing 47% of the aggregate. ESG loans followed at KRW 753 trillion, representing 37.4%, while ESG bonds contributed KRW 247.5 trillion, accounting for 12.3% of the total. The relative weight of each segment reflects the structural character of South Korea's financial system, in which the combined volume of institutional asset management and bank lending substantially exceeds the country's capital markets by total assets deployed.
Sustainability-linked loans — products that tie borrowing costs to the achievement of pre-agreed environmental or social performance targets — declined by 20.6% year-on-year, the sharpest contraction among the major product categories tracked by KoSIF. The fall mirrors trends observed in European markets, where heightened scrutiny of the stringency of sustainability-linked loan targets has prompted both borrowers and lenders to step back from the product structure. KoSIF data also showed that only 29 institutions offered renewable energy financial products, suggesting that availability remains concentrated in a small segment of the financial system rather than broadly distributed across lenders of different sizes.
INSTITUTIONAL COVERAGE AND STRUCTURAL GAPS PERSIST
The concentration of ESG finance provision among a relatively limited number of institutions has been identified by South Korean regulators and market participants as a structural constraint on the market's next stage of expansion. The country's financial regulators have been developing ESG disclosure guidelines applicable to listed companies, but the translation of disclosure obligations into active product development at smaller and regional financial institutions has been considerably slower than at the large listed banks and asset managers that dominate the KoSIF data.
The KoSIF findings arrive as ESG finance globally faces political and regulatory headwinds in several major jurisdictions. For South Korea, the domestic context includes ongoing policy debates about how ESG criteria should interact with industrial policy priorities, particularly for energy-intensive export industries such as steel, shipbuilding, and petrochemicals that are central to the country's economic structure. Whether the 2024 deceleration proves temporary or marks a more durable structural plateau will depend in part on how those competing priorities are resolved in the regulatory frameworks taking shape over the period ahead.
