Earlier this year, the Association of Southeast Asian Nations (ASEAN) concluded negotiations on the Digital Economy Framework Agreement, or DEFA—the world’s first comprehensive, region-wide agreement dedicated to the digital economy. The pact is expected to be signed at the ASEAN Summit this November, when leaders from the group’s 11 member states will converge in Manila. 

DEFA may sound like the sort of acronym-laden agreement that disappears quickly from the headlines. It should not. The agreement is an attempt to do for the key elements of modern digital trade—data, digital payments, e-commerce, online consumer protection, and AI—what trade agreements once did for ports, tariffs and containers: create common rules and standards to drive seamless commerce across borders.

DEFA is an overlooked attempt to solve one of the digital economy’s defining problems: commerce is increasingly borderless, but the rules governing it are not. Signing the agreement will only be the first step; ASEAN’s 11 members will have much work to do to make DEFA work in practice. But if they succeed, they’ll show how different economies can integrate while still preserving their differences.

Asia’s next great growth story won’t be a single country growing into “the next China.” It will be a region—ASEAN, in this case—finding ways to connect itself and reaping the rewards of that closer integration.

Companies operating across Southeast Asia today must often navigate 11 different regulatory environments. Large companies may be able to shrug off those compliance costs, but for a small manufacturer in Bangkok or Surabaya, it can be the difference between serving one market and reaching many.

DEFA aims to make that leap easier. If implemented well, it can give regional hubs greater reach, help global companies build more consistent operations across ASEAN, and allow small businesses to connect more readily with new customers, suppliers and partners beyond their home borders.

The opportunity in ASEAN is immense. A benchmark study by Google, Temasek and Bain estimated that the region’s digital economy surpassed $300 billion in gross merchandise value in 2025. ASEAN’s own studies project that the region’s digital economy could reach $1 trillion by 2030 on its current trajectory—and potentially touch $2 trillion if policymakers implement DEFA rules expeditiously.

These figures will only grow as ASEAN’s middle class comes into its own. As Wolfgang Fengler of World Data Lab underscored at Mastercard’s ASEAN Inclusive Growth Summit last year in Kuala Lumpur, Southeast Asia is now at a “middle-class majority” tipping point. By 2032, ASEAN’s middle class will have grown by 112 million.

This middle-class cohort will shape ASEAN’s growth and digital consumption patterns for decades. But it will also bring about a deeper change that won’t show up in GDP figures. When people enter the middle class, they don’t just consume more. They expect more: better services, safer transactions, access to capital, protection from fraud, and room to grow their small businesses.

That is why DEFA is so critical. Through rules that promote cross-border data flows, regional commerce, and harmonized cybersecurity standards, DEFA will help ASEAN embrace the modern-day digital economy. At the same time, it is sending a broader signal to policymakers and corporate leaders around the world: integration still matters, even in this age of tariffs, trade wars, and digital sovereignty.

Since its founding in 1967, ASEAN has had to embrace both integration and diversity. Its membership includes advanced hubs like Singapore, emerging markets like Indonesia, and small island economies like Timor-Leste. ASEAN’s leaders have navigated this diversity by striving for commonality, not conformity, in how they bridge different systems.

Global leaders should pay attention to DEFA, as it shows one way that regions can foster growth in the digital age without eroding trust, deepening inequality or stifling innovation.

Small and medium enterprises (SMEs) are eager to reach regional markets, yet they face uneven rules, fragmented payment systems, and different standards from country to country. Every additional layer of friction translates into forgone sales and lost revenue—not just for the business, but also for governments who see the digital economy as a key source of tax revenue.

Of course, DEFA will not solve all these issues overnight. The hard work comes after the ink dries in Manila, and it will require policymakers, industry partners, and civil society to bring the agreement to life.

The real litmus test will be how DEFA works for ordinary people and businesses. Can payments clear securely across borders? Can consumers participate online without falling prey to scammers? Can small businesses sell beyond their home markets and grow cross-border orders?

Assuming the agreement can deliver these outcomes, DEFA will be remembered as more than a diplomatic milestone. It will mark a moment when Southeast Asia asserted leadership in the digital domain.

And if ASEAN’s bet pays off, it won’t just carry Southeast Asia into the digital future. It may show others how to get there too.
