Impact on Foreign Exchange and the AI Industry

The "coordinated yen-buying intervention (a rapid shift from the 164 yen range to the 157 yen range) for the first time in about 28 years" implemented at the end of July 2026 has brought asymmetric (contrasting) ripple effects to the AI industries in Japan and the U.S. in terms of both market sentiment and cost structure.
Beyond mere "fluctuations in exchange rate figures," there are impacts on the AI industries in both Japan and the U.S. across three axes: "Capex (capital investment) efficiency of AI infrastructure investment," "evaluation of earnings (ROI)," and "geopolitical and supply chain strategy."

1. Impact on Japan's AI industry: "Temporary easing" and "selection" of structural high costs

Since Japan's AI ecosystem relies heavily on the U.S. (dollar-denominated) for AI models (OpenAI, Anthropic, etc.), hardware (NVIDIA GPUs, etc.), and cloud infrastructure (AWS, Azure, etc.), exchange rate fluctuations have a direct impact.

① Reduction in procurement costs for AI infrastructure and computing resources (positive)

Suppression of hardware import prices: In the super-weak yen phase of 164 yen to the dollar, procurement budgets for NVIDIA's latest GPUs, server equipment, and cooling facilities for data centers were significantly squeezed.
The strengthening of the yen to the 157 yen range (briefly reaching the 155 yen range) lowers the procurement costs (in yen) for computing resources for domestic cloud operators, major telecommunications companies, and research institutions, providing a breather for AI data center expansion plans.

"Purchasing power defense" for promoting Sovereign AI: In "Sovereign AI (building domestic LLMs and domestic computing infrastructure)" led and subsidized by the Japanese government, the risk of the external purchasing power of subsidies diminishing has been temporarily avoided.

② Curbing the burden of cloud and API usage fees (running costs)

Reducing profit pressure on AI startups and SaaS operators: API usage fees for OpenAI and others, and dollar-denominated cloud usage fees for AWS and others, were directly hitting the running costs of domestic AI ventures and companies. With the rapid depreciation of the yen being halted, controlling inference costs and model development expenses has temporarily become easier.

③ Tightening of the domestic investment and fundraising (VC) environment

Selection by overseas money targeting "cheap yen": Extreme yen depreciation made Japanese AI startups look "cheap" from the perspective of overseas VCs, but with the coordinated intervention and the accompanying prospect of additional interest rate hikes by the Bank of Japan (rising interest rates), easy carry-trade-style capital supply will recede.
From now on, a severe selection process will proceed toward "companies with clear profit models" rather than "companies that simply use AI."

2. Impact on the U.S. AI industry: "Improvement of export environment" and "stricter ROI" due to correction of strong dollar

In the U.S., the AI market is currently shifting from "expectations (PoC)" to a "practical verification phase that strictly questions returns (ROI) on huge investments." The "correction of excessive dollar strength" through coordinated intervention has the following effects on major U.S. AI companies.

① Preventing the erosion of "overseas earnings" for hyperscalers and AI companies

Recovery of translation gains from overseas sales: For U.S. Big Tech and AI companies such as Microsoft, Alphabet, Meta, and Palantir, excessive dollar strength was a factor in pushing down performance (exchange rate headwind) when converting sales from overseas markets, including Japan, into dollars. With the strong dollar being corrected to a certain extent, the negative impact of exchange rates on the performance of globally expanding AI companies will be mitigated.

② Maintaining price competitiveness of U.S.-made AI hardware (NVIDIA, Intel, etc.)

Synergy with export tariffs and trade policy: While the super-weak yen exceeding 160 yen gave excessive price competitiveness to Japanese semiconductor parts and equipment manufacturers, it relatively inflated the overseas sales prices of cutting-edge AI chips (Intel 18A, etc.) manufactured and exported within the U.S. The correction of the strong dollar supports both "the return of manufacturing to the U.S." and "global exports of cutting-edge AI hardware".

③ Cooling down investor sentiment and the "AI bubble theory"

Vigilance against rising cost of capital (WACC): Behind the U.S. participation in the coordinated intervention was the intention to prevent the risk that "Japan would sell a large amount of U.S. Treasuries for unilateral intervention, causing U.S. long-term interest rates to soar." The avoidance of a sharp rise in U.S. interest rates provides a floor for high-valuation (high stock price) AI tech stocks, but on the other hand, for "overheated mega-Capex (capital investment)," the market will strengthen its tendency to more strictly demand return on investment (ROI).

3. Japan-US AI Industry

Since the Japanese AI industry relies on the United States (dollar-denominated) for much of its foundational infrastructure and software, cost performance improves as the yen strengthens.

Procurement costs for servers and GPUs become cheaper
Because cutting-edge GPUs like those from NVIDIA and AI-dedicated servers are fundamentally priced in dollars, a shift toward a stronger yen allows Japanese data centers and companies to procure more computing resources (AI infrastructure) with the same budget.

Monthly costs (running costs) for cloud and APIs are reduced
Payments to services such as OpenAI, Anthropic, AWS, and Azure are dollar-denominated (or dollar-linked). A stronger yen means more profit remains in the hands of Japanese AI startups and business enterprises.

The movement from 164 yen to 157 yen due to this coordinated intervention can be understood as having brought a 'positive impact (benefit) of easing the burden of procurement and operations' to the Japanese AI industry, which had been suffering from high costs due to excessive yen depreciation.
