High savings, internal cash flows, and local-currency bank loans will support Asia's capex supercycle

Overview

The report examines how Asian companies will finance a new capex cycle. Morgan Stanley concludes that Asia has high domestic savings, current account surpluses, and relatively ample corporate cash, while external financing is dominated by local-currency bank loans. Capex acceleration is therefore not expected to encounter a significant macro funding bottleneck.

Core views

The report first characterizes the current rise in Asian capex as a potential supercycle that could approach the mid-2000s cycle in intensity and duration. AI and related digital infrastructure, energy, defense, and broader industrial investment form four interconnected structural drivers. Asian companies need both to catch up with US investment in AI and to serve as major suppliers in the global AI supply chain. AI-related power consumption, the energy transition, and energy security are driving energy investment higher; geopolitical tensions are reinforcing existing defense budget expansion; and supply-chain localization is transmitting this spending into the broader industrial system. The report expects Asian capex to rise from US$11 trillion in 2025 to US$16 trillion in 2030. Detailed estimates show total capex increasing from US$12.11 trillion in 2026 to US$15.69 trillion in 2030. Combined capex by AI hyperscalers and semiconductor manufacturers rises from US$450 billion to US$830 billion, capex driven by new structural demand increases from US$1.61 trillion to US$2.75 trillion, broad industrial capex rises from US$4 trillion to US$5.24 trillion, and other capex grows from US$6.5 trillion to US$7.7 trillion. Regarding macro funding constraints, the report argues that capex and export growth will raise productivity and aggregate corporate-sector savings, causing savings to increase faster than investment and recreating the widening current account surpluses seen across most Asian economies in the mid-2000s. Eight of the region's 12 economies currently run current account surpluses, and the report expects this trend to continue through 2027. Asia's current account surplus as a share of GDP has also risen to a post-global-financial-crisis high. Therefore, even as corporate financing demand rises alongside capex, domestic savings should still provide the primary funding base. Asia differs markedly from the United States in its external financing structure. After internal corporate cash flows, bank loans remain Asia's most important channel for financing capex, whereas the United States relies more heavily on market-based instruments and non-bank finance. As of the first quarter of 2026, loans accounted for 70% of total business-sector financing in China and approximately 60% in Asia excluding China. The report's summary of recent financing flows in Asia excluding China shows loans at approximately 70% and equity at approximately 9%. In China, debt securities account for 15%, ranking behind loans. Equity and investment fund shares are typically Asia's second-largest source of funding, while credit markets play a less important role, reflecting the fact that Asian credit markets are less developed than those in the United States. Compared with Asia, the euro area relies more on a combination of loans and equity-market financing. US dollar financing is not the preferred choice for Asian companies in this cycle. Local interest rates in Asia are lower than US rates, while Asian currencies face depreciation pressure, making US dollar debt more costly and riskier in exchange-rate terms than local-currency financing. Asian economies are therefore expected to continue relying on local-currency markets, and net issuance of Asian US dollar credit has been negative for four consecutive years. The report argues that this does not reflect inadequate overall financing capacity, but rather an active shift in financing activity toward lower-cost local bank loans and other local-currency channels. The funding structure of AI capex further reduces pressure on external markets. The report expects Asian AI capex to surge from US$80 billion in 2025 to US$195 billion in 2026 and reach US$250 billion in 2027, although it will remain below the US level. Approximately 85% of the funding is expected to come from internal accruals and balance-sheet cash. The residual cash balances of major Asian semiconductor companies are still increasing, and the report believes their capex could potentially be funded entirely with internal cash. By comparison, total US AI-related financing needs amount to US$3.21 trillion, of which 54.5% is expected to be provided by credit markets, indicating significantly greater US reliance on external credit financing. Financing mixes vary across economies. In China, banks provide 70% of funding, with debt securities ranking second at 15%, but domestic demand remains relatively weak and the recovery in corporate financing flows has been comparatively modest. Japan's financing is highly skewed toward loans, which now account for more than 100% of net financing, partly because share buybacks have turned equity financing negative; debt securities are a distant second. Loans remain South Korea's largest funding source, but trade credit, accounts payable, foreign direct investment, and external claims have also recovered, making the financing structure increasingly diversified. Bank loans have led the recent recovery in Indian corporate financing, with foreign direct investment and equity and investment fund shares serving as supplementary channels. In Taiwan, trade credit and accounts payable are the largest funding source, surpassing loans, while equity financing also plays an important role. In Australia, loans and equity or investment fund shares jointly dominate financing in nearly equal proportions. Finally, the report assesses the cycle's durability based on balance-sheet capacity. As of December 2025, non-financial corporate credit in Asia excluding China stood at 74% of GDP, below 75% a decade earlier, indicating that capex acceleration is not built on materially higher corporate credit leverage. Meanwhile, bank credit growth in Asia excluding China has risen to a 19-year high. Morgan Stanley therefore concludes that bank loans will remain the dominant external financing channel for corporate capex in this cycle, while relatively moderate starting leverage, high savings, and internal cash flows will extend the capex cycle.

Analysis framework

The report first identifies four categories of structural demand—AI, energy, defense, and industrial investment—and estimates their contributions to total capex from 2026 to 2030. It then assesses macro funding sufficiency through the relationship among savings, investment, and current accounts, before breaking down corporate funding sources into internal cash flow, loans, equity, bonds, trade credit, and foreign direct investment and comparing them with the United States and the euro area. Finally, the report evaluates the banking system's financing capacity using four-quarter rolling financing flows, corporate credit as a share of GDP, and economy-level data. Its treatment of Chinese financing flows excludes government bond financing and deducts changes in outstanding consumer loans to better approximate business-sector financing.

Impact & implications

The report argues that Asian capex expansion will not depend primarily on the US dollar bond market, but will instead be supported by internal corporate cash, local-currency bank loans, and some equity financing. The banking system will therefore remain the key external funding provider for the capex cycle, while the strong cash positions of AI and semiconductor companies can further reduce external financing pressure. Current account surpluses and relatively moderate corporate credit leverage mean that rising investment need not quickly translate into an external funding gap, helping extend the current industrial and capex cycle.
