What’s Behind the IMF’s 0.4-Point Upgrade to Asia-Pacific Growth?

By Yuanyin in Tokyo

On October 15, during its annual meetings in Bangkok, the International Monetary Fund released its latest Regional Economic Outlook for Asia and the Pacific, raising its 2026 growth forecast for the region from 4.4% to 4.8%.

A 0.4-percentage-point upgrade may not look dramatic. But against a backdrop of weaker global growth and lingering energy shocks from the Middle East, the revision deserves attention.

IMF Asia and Pacific Department Director Krishna Srinivasan summarized the drivers clearly: the energy shock had a significant negative impact, but economies adapted better than expected; the AI boom provided varying but broadly positive support; and trade remained “quite resilient” despite tariff disruptions.

Two positive forces offset one major negative shock.

That raises the next question: who are the growth leaders, and who is providing the floor?

AI Moves From Concept to Physical Infrastructure

One line in the IMF report stands out: “strong demand for AI-related technologies.”

The most direct beneficiaries are economies embedded in the semiconductor and computing-hardware supply chain.

The IMF sharply raised its 2026 growth forecast for South Korea, while its forecast for Taiwan reached 10.7%, up 5.5 percentage points from its April estimate. Such a large revision cannot be explained by household consumption or domestic demand alone. It reflects booming exports of AI-related hardware — advanced semiconductors, server components and data-center equipment.

For South Korea, the IMF even expects potential growth to rise for a second consecutive year, driven by the AI-related semiconductor boom. If realized, it would be the first such increase in around four decades.

But the benefits are highly uneven.

The IMF has described many economies as showing a K-shaped growth pattern: technology-related sectors are expanding rapidly while other sectors lag behind. Growth in advanced Asian economies is expected to accelerate from 2.5% last year to 3.2% in 2026, while emerging Asia is projected to slow from 5.6% to 5.1%, partly because of higher energy prices.

In other words, the AI boom is creating a new dividing line across Asia-Pacific.

Economies deeply integrated into the computing-hardware chain are benefiting. Those that rely heavily on imported energy but lack technological depth are under greater pressure.

The pattern can be seen in a single AI server. Its production may involve Korean memory chips, Taiwan-based manufacturing, assembly and thermal-management components from mainland China, and data-center infrastructure in Southeast Asia.

A meaningful share of the IMF’s 0.4-point upgrade is hidden in the customs declarations generated at each stage of that chain.

Where Is the Resilience in Intra-Asian Trade?

The IMF’s second major support factor is the resilience of trade within Asia.

More precisely, while trade with the United States has weakened, intra-Asian trade has increased significantly.

For years, markets have focused on “decoupling” and “friend-shoring,” but the actual restructuring of trade flows has been more complicated than a simple relocation of production.

The IMF noted that Asia-Pacific governments have largely resisted the temptation to introduce more restrictive measures and have instead continued to deepen regional trade arrangements.

Under the RCEP framework, intermediate goods, electronic components and industrial parts continue to move across borders. In a period of tariff uncertainty, this regional network has created a degree of internal stability.

The economies receiving some of the largest forecast upgrades — including India, South Korea and parts of Southeast Asia — are also among those benefiting from strong technology-supply-chain demand.

That matters because technology supply chains depend heavily on repeated cross-border movements of intermediate goods. The final assembly location of a device may account for only a small share of its total value added, while components may cross several borders before the finished product is completed.

RCEP’s tariff reductions and cumulative rules of origin reduce the cost of these movements.

Energy trade is also changing. Higher oil prices caused by Middle East tensions have pushed some Asian economies to adjust their sourcing strategies. China has drawn on oil reserves and expanded renewable-energy use, while India and Japan have sought alternative energy suppliers.

These adjustments cannot fully offset the Middle East shock, but they are contributing to denser economic links within the region.

China: A Stabilizing Anchor and Multiplier

Srinivasan offered one particularly striking estimate:

A one-percentage-point increase in China’s growth could lift growth in other regional economies by around 0.3 percentage point.

He also emphasized that China accounts for more than half of Asia-Pacific GDP and contributes roughly one-third of global economic growth.

What does that 0.3 multiplier mean?

In rough terms, if China were to grow one percentage point faster than the baseline because of stronger policy support or improved external conditions, the combined effect on the rest of Asia-Pacific could be comparable to the annual growth contribution of a medium-sized economy.

The effect comes from two channels.

China is a major source of final demand, pulling in imports from neighboring economies. At the same time, it remains a central node in regional intermediate-goods supply chains, importing components and raw materials that are either absorbed domestically or incorporated into exports.

But China’s role in the current cycle is different from that of the region’s technology-export leaders.

The IMF’s upgrade applies to the region as a whole, while China’s growth pattern is not identical to that of economies benefiting directly from the AI hardware boom.

China’s response to energy shocks — drawing on reserves, restraining demand and accelerating renewable-energy substitution — reflects a stronger shock-absorption function than an AI-driven acceleration effect.

In this sense, China acts more as a stabilizing base for regional demand and supply-chain resilience than as the most visible growth engine in this particular upgrade.

The Hidden Side: K-Shaped Growth and the Fragility of the AI Boom

The IMF also provides several clear warnings.

First, low-income economies and Pacific island countries are being left behind.

The IMF has lowered growth forecasts for a number of these economies, in some cases significantly. Diesel remains essential for power generation in low-income countries, while aviation fuel is critical for remote island economies. Higher fuel prices therefore hit directly at their growth foundations.

When the regional average is revised upward, these downward revisions can easily disappear from view.

Second, the concentration of the AI boom is itself a risk.

The IMF has warned that South Korea is benefiting disproportionately from the AI upcycle, but that this also makes the country increasingly exposed to changes in the AI business cycle.

If the boom reverses sharply, exports could fall, investment could weaken, and tax revenues and financial conditions could deteriorate.

The same logic applies to other semiconductor-exporting economies in Asia.

Asia-Pacific’s exposure to a single technology cycle is increasing, not decreasing.

Third, fiscal buffers are not unlimited.

Many governments have introduced broad support measures that are not always well targeted, increasing pressure on public finances. At the same time, sovereign bond yields across Asia have risen sharply, reflecting growing investor concerns over fiscal sustainability.

The cost of adapting to energy shocks ultimately has to be absorbed somewhere — and in many economies, fiscal space is already becoming tighter.

Taken together, these warnings point to one conclusion:

The 4.8% forecast is credible, but the real story is that Asia-Pacific’s growth engine is changing.

The new engine — AI hardware and intra-regional trade — is powerful, but highly concentrated and unevenly distributed.

The old buffers — fiscal space, energy reserves and low-cost labor — are being consumed.

And China’s role in this transition is increasingly that of a stabilizer: helping the region shift gears without stalling, even if it is not the source of the strongest acceleration in this particular cycle.
