In the last two decades, Asia has quietly redrawn the global capital markets map. The transformation, as highlighted in the OECD’s 2025 Asia Capital Markets Report, is not just quantitative, it’s structural, strategic, and signals a long-term shift in the global economic centre of gravity.
Between 2000 and 2024, the number of listed companies in Asia surged by over 14,300, a stark contrast to the U.S. and Europe, which saw net declines of 2,243 and 1,055 respectively.
Market capitalisation followed suit: Asia added $25 trillion, while Europe stagnated. Only the U.S., bolstered by megacap tech giants, outpaced Asia in total growth, adding $35 trillion. Meanwhile, Asia’s corporate bond market outperformed both Europe and the U.S., expanding by $8.8 trillion.
These figures underscore a deepening reliance on market-based financing in Asia, but also raise an important question: is this enough to support the region’s outsized economic ambitions?
“Asia now accounts for 55% of all listed companies globally and 27% of total global market capitalisation,” according to the OECD (2025). That’s more than symbolic. It’s structural rebalancing.
The SME Financing Dilemma
Yet beneath the impressive headline growth lies a troubling bifurcation. In many Asian economies, especially in emerging and developing markets, the financial ecosystem remains overly reliant on banks.
While countries like Korea, Japan and Malaysia show relatively balanced capital structures, others, such as Cambodia, Sri Lanka and Viet Nam, have bank credit-to-GDP ratios that far exceed the global average, while the use of capital markets remains negligible.
The result? A large share of companies, particularly SMEs, remains financially constrained and unable to scale or innovate.
Despite comprising the backbone of the region’s private sector, 70% of MSMEs in emerging markets still lack adequate financing, according to the International Finance Corporation (IFC, 2024).
Traditional bank lending remains limited due to strict collateral requirements, with over 70% of loans in many countries still requiring security, and a widespread perception that SMEs are too risky.
The OECD’s 2025 data shows: in emerging Asian economies such as the Philippines and Viet Nam, constrained firms report significantly lower sales growth than their unconstrained peers. In sectors where innovation and scale are essential, such barriers are not merely operational, they are existential.
Capital Markets: A Conduit for Innovation and Sustainability
The real opportunity, and challenge, lies in capital markets’ role in unlocking innovation. The OECD shows that following an IPO, investment in capex and R&D increases significantly, especially in Asia’s technology and healthcare sectors.
For tech companies in the region, capital expenditure jumps from 7.5% to 11.4% of sales within three years of going public.
This relationship isn’t accidental. Innovation, by nature, demands risk-tolerant, long-horizon capital. Banks, by mandate and structure, are often ill-equipped to provide it.
Public equity markets, by contrast, pool resources from diverse investors and spread risk across portfolios. The result is not just better-funded firms, but more resilient, globally competitive industries.
China, Korea, Japan and Chinese Taipei exemplify this trend. These economies boast some of the deepest capital markets in Asia and have birthed world-leading companies in sectors like semiconductors, advanced manufacturing and biotech.
Notably, venture capital in China alone reached 5% of GDP by mid-2024, surpassing levels in North America and Europe.
But capital markets aren’t just about unicorns. They’re also about climate.
“Asia’s emerging economies face a $1.1 trillion annual climate finance gap, yet receive just $333 billion today,” notes the OECD, referencing data from Basu and Cheng Hoon (2024).
Without robust capital markets, the region simply cannot meet its decarbonisation goals. Sustainable bonds, equity, and green finance mechanisms are crucial to scaling renewable infrastructure and energy-efficient technologies.
Yet limited transparency, weak taxonomies and patchy regulatory standards continue to undermine investor confidence. Greenwashing concerns persist, keeping the cost of capital high for sustainable initiatives.
Uneven Growth, Unequal Access
Asia’s capital market growth is not monolithic. While Hong Kong and Chinese Taipei boast market capitalisation-to-GDP ratios exceeding 200%, many others, such as Bangladesh, Pakistan and Cambodia, remain below 40%.
This disparity reflects deeper challenges: from low investor participation and liquidity to inconsistent legal frameworks and shallow institutional investor bases.
It also highlights the critical importance of growth markets, specialised equity segments for high-potential SMEs and scale-ups.
Asia leads globally here, with over 8,500 listed growth companies accounting for 80% of global growth market capitalisation.
China dominates, listing over 2,000 such companies worth $2.5 trillion. Japan, Korea and India are also active players.
These markets operate under more flexible listing rules, often with reduced governance and financial requirements tailored to early-stage firms.
Sponsor models, as used in Hong Kong and Malaysia, help smaller firms navigate regulatory hurdles, while government-led initiatives in Korea, Malaysia and Singapore aim to boost research coverage and investor visibility.
Yet challenges remain. Thin liquidity, limited analyst coverage and institutional investor caution continue to constrain growth markets’ effectiveness.
The cycle is vicious: without visibility, there’s no liquidity; without liquidity, there’s no investor confidence.
The SOE Factor
State-owned enterprises (SOEs) continue to play an outsized role. At the end of 2024, SOEs accounted for 26% of market capitalisation in Asia, five times higher than in the rest of the world. In China, Malaysia, Singapore and Viet Nam, the figure exceeds one-third.
Critically, SOE listings have historically catalysed market development. China’s exchanges were launched precisely to float SOEs.
Viet Nam’s equitisation programme had a similar effect. Listing SOEs imposes market discipline, improves transparency, and boosts overall market depth. But it also poses risks: overconcentration, crowding out private firms, and political interference.
Asia’s rise in capital markets is a story of reform, but the next chapter must be about resilience. Regulatory harmonisation, deeper institutional investor pools (especially pensions and insurance funds), enhanced disclosure standards, and support for sustainable finance will be essential.
Market-based finance offers Asia more than capital. It offers a path to technological self-reliance, climate leadership and inclusive growth.
But this promise will only be realised if capital markets evolve from fragmented growth engines into integrated financial ecosystems.
As the OECD (2025) rightly concludes: “Asia has a strong capital market foundation, but continued reforms are needed to facilitate access to market-based financing and expand the institutional investor base. This will help ensure Asia’s capital markets match its economic significance and support sustained growth.”
The future of Asia’s economy will be written not only in factories or tech parks, but in trading floors, IPO prospectuses and green bond frameworks. The infrastructure of growth is financial. And in that race, Asia cannot afford to slow down.
