Bangkok, April 8, 2026 — Thailand's Capital Market Supervisory Board has formally approved regulatory frameworks for two new categories of debt instruments, transition bonds and "amber" bonds, while the country's Securities and Exchange Commission announced it expects to achieve regulatory clarity for Bitcoin ETFs and crypto-linked bonds by the third quarter of 2026. The related announcements from Thailand's capital market regulators position the country as one of the most advanced regulatory environments for digital assets in Southeast Asia, simultaneously advancing sustainable finance and digital asset infrastructure.

New Bond Categories

Transition bonds allow issuers to raise capital specifically for projects that facilitate climate transition, a scope that encompasses reducing carbon-intensive operations as well as broader adaptation and resilience efforts.

Amber bonds cover activities that still produce emissions but are verifiably on a science-based decarbonisation pathway consistent with both the Thailand Taxonomy and the Paris Agreement.

Phase 2 of the Thailand Taxonomy, launched in May 2025, uses a traffic-light classification system. Green denotes already-sustainable activities. Red designates activities judged incompatible with any credible decarbonisation pathway. Amber sits between the two, covering sectors including energy, transport, manufacturing, construction, waste management, agriculture, and aquaculture that have not yet reached net-zero but carry credible timelines for doing so, with a sunset date of 2040. The amber bond category gives investors a regulated vehicle for financing activities that are too emissions-intensive to qualify as green but are not disqualified by the red designation.

The CMSB's new framework converts amber from a classification label into a fundable bond category, opening regulated public markets to transitional-stage projects that previously had no dedicated financing vehicle.

Anek Yooyuen, Deputy Secretary-General and Spokesman of the Thailand SEC, said the new rules would enable issuers to raise funds for "transition-related projects and 'amber' activities" that still generate emissions but remain aligned with science-based pathways under the Thailand Taxonomy and the Paris Agreement.

Thailand's sustainability bond market already stood at roughly THB 910 billion (approximately USD 25.4 billion) in outstanding issuance as of mid-2025, representing about 5.3 percent of the total domestic bond market, according to THAIBMA data. Separately, ADB AsianBondsOnline figures, which draw on a broader data universe, indicate the sustainability bond segment grew approximately 34 percent year-on-year in 2025. Across both measures, the market is roughly 40 times larger than it was in 2019.

The SEC is also tightening disclosure standards across all sustainability-linked bonds to improve transparency and market credibility.

Bitcoin ETF Framework: Highest Risk Classification

Thailand's SEC expects to achieve regulatory clarity for Bitcoin ETFs and crypto-linked bonds by the end of Q3 2026.

The announcement builds on the country's June 2024 approval of its first spot Bitcoin ETF, issued by One Asset Management under the fund name ONE-BTCETFOF-UI.

That fund operates as a fund of funds, pooling exposure across 11 leading global Bitcoin ETFs and restricting access to institutional and high-net-worth investors.

The forthcoming framework will extend beyond a single product approval to set industry-wide rules on risk classification, disclosure requirements, and manager qualifications.

Yooyuen was direct about how these products will be treated: "Given the inherently high volatility of digital assets, these products will be classified at the highest risk level compared with traditional equity funds."

Asset managers seeking to offer Bitcoin ETFs or crypto-linked products must demonstrate sufficient expertise in handling complex and volatile assets and will be required to make clear disclosures about pricing sources and trading mechanisms.

Under existing rules, retail mutual funds in Thailand are capped at a 15 percent portfolio allocation to crypto assets, while institutional and high-net-worth investors face no allocation ceiling. Whether the forthcoming Q3 2026 framework will revise that retail cap has not yet been confirmed.

The market context underscores the regulator's caution. Bitcoin was trading at approximately USD 71,926 on April 8, having posted a 23 percent loss in the first quarter of 2026, its worst Q1 performance since 2018. The token was nevertheless up approximately 4.5 percent on the day itself, supported by geopolitical developments. The Crypto Fear and Greed Index sat at 9, a reading classified as extreme fear, with the market having remained in that zone for roughly 59 consecutive days as of late March.

Tokenised Securities on the Same Timeline

The SEC is simultaneously developing frameworks for tokenised securities and digital asset-linked bonds, targeting the same Q3 2026 window.

As of February 2026, the regulator was conducting public hearings on tokenised mutual funds, units issued via blockchain, with a tentative effective date in late Q2 2026.

The Bank of Thailand significantly expanded its Thai baht-backed stablecoin sandbox in December 2025, with open applications and no submission deadline.

Yooyuen has also stated that investment tokens will carry the same investment ratios as transferable securities such as stocks and bonds, on the basis that they share similar characteristics and risks.

Regional Context

Thailand's progress widens an already significant gap with most of its Southeast Asian neighbours.

Singapore maintains tight restrictions on retail access to crypto investment products, though it has established a licensing regime for crypto service providers through the Monetary Authority of Singapore.

In South Asia, the picture is mixed. India maintains a 30 percent capital gains tax on crypto with no ETF pathway. Pakistan passed a Virtual Assets Act in March 2026, establishing a federal licensing body with Shariah-compliant provisions and FATF-aligned anti-money-laundering protocols, though the act does not include an ETF component. Bangladesh maintains an outright prohibition on cryptocurrency. Sri Lanka has no active digital asset framework at this stage.

Hong Kong currently leads the Asia Pacific region with 18 spot, futures, and inverse Bitcoin and Ethereum ETFs listed on its exchange.

Thailand's framework is aimed at a comparable depth of product coverage while extending the model into bond markets. Based on publicly available regulatory information, no other Asian jurisdiction appears to have yet attempted that combination at scale.

For developers building regulated financial infrastructure, the SEC's explicit requirements around pricing source disclosure and trading mechanism transparency effectively create technical specifications for on-chain oracle and settlement systems.

With public consultations still open ahead of Q3 finalisation, builders have a concrete window to engage before the rules are locked.

Thailand's coordinated push across climate bonds, digital assets, and tokenised securities fits within the SEC's 2026 to 2028 strategic plan, titled "Building Trust, Powering Growth," which provides the institutional backdrop for a regulatory overhaul that extends well beyond any single product category. The scale of the domestic market gives the push commercial weight: roughly 8.2 million active Thai crypto traders, approximately 11.6 percent of the population, give the SEC both an economic incentive and a consumer-protection mandate to move quickly. Regional peers are watching. As Thailand raises the floor on regulatory infrastructure across sustainable finance and digital assets in parallel, neighbouring markets face growing pressure to respond in kind.
