For every dollar directed toward fossil-fuel projects in 2024, banks headquartered across eight key Asia Pacific economies facilitated just 83 cents in clean energy financing. This figure, detailed in the May 14, 2026 report by BloombergNEF, Energy Supply Ratios for Investment and Financing in Asia, highlights a persistent structural imbalance in the region’s capital allocation. While this represents a high-water mark for the ratio since 2021, it remains firmly below the global benchmark of 0.89:1, signaling that regional financial institutions are struggling to outpace the inertia of legacy energy dependencies.
The Financing Gap in Asia Pacific
Follow the money across the region—encompassing Japan, South Korea, Taiwan, Singapore, Malaysia, Thailand, Indonesia, and the Philippines—and a clear trend emerges: fossil-fuel financing is declining at a glacial pace, while low-carbon capital inflows remain stagnant. Between 2022 and 2024, banks across these markets facilitated approximately $240 billion in annual energy supply financing. Despite the rhetorical shift toward sustainability, total low-carbon transactions in 2024 actually failed to surpass 2021 levels, remaining consistently dwarfed by fossil-fuel supply volumes.
The data suggests that the "green" transition in these markets is currently being driven by specific infrastructure needs rather than a wholesale pivot in banking strategy. While wind and solar financing remained broadly flat between 2023 and 2024, the growth in low-carbon portfolios was primarily buoyed by investments in power grids and energy storage. Large-scale projects, such as the financing of the largest solar and battery installation in Southeast Asia, have demonstrated that individual massive deals can disproportionately swing national performance metrics, masking the lack of broader, systemic shifts.
Institutional Divergence and Market Realities
Not all institutions are moving at the same speed. The report identifies a cohort of banks that successfully improved their low-carbon-to-fossil-fuel ratios in 2023 and 2024, including Japan’s MUFG and Mizuho, Taiwan’s Mega Financial Holding, Indonesia’s Bank Mandiri, Malaysia’s Maybank, and Thailand’s Krung Thai Bank and Kasikornbank. These improvements often reflect domestic realities; for instance, banks in Thailand and Indonesia saw fossil-fuel transaction volumes dip simply because local energy giants PTT and Pertamina required less refinancing.
The international influence is equally notable. Standard Chartered, BNP Paribas, Groupe BPCE, and Deutsche Bank remain significant players, facilitating energy supply financing within these Southeast Asian markets. However, the domestic-versus-international split can be stark. Japanese banks, for example, achieved a commendable 1.27:1 ratio within their home market, yet this progress was effectively diluted by their continued involvement in fossil-fuel deals across North America and Southeast Asia.
The Disconnect Between Investment and Alignment
The urgency for a shift is underscored by the 2026 energy shocks, which have exposed the systemic risks of fossil-fuel dependency. Although energy transition investment in the Asia Pacific region (excluding mainland China) grew by 23% in 2025—outstripping the global growth rate of 8%—the capital efficiency remains insufficient. The region saw only $1.30 invested in low-carbon supply for every dollar in fossil-fuel supply, lagging significantly behind Europe’s 3.5:1 ratio.
For the average investor, this mismatch presents a long-term risk. Achieving alignment with 1.5-degree warming scenarios requires a global average ratio of 4:1 by the end of the decade. As institutions like JPMorgan Chase, Citigroup, and Scotiabank adopt rigorous financing ratio disclosures, these metrics are becoming essential tools for internal benchmarking. The next reading of these energy supply ratios will serve as the primary signal of whether regional banks are merely engaging in window dressing or fundamentally restructuring their portfolios to mitigate the high costs of fossil-fuel volatility.
