Article 1

U.S.-China Tensions Become Clear at the Shangri-La Dialogue

Taiwan and Security Become the Biggest Focus

At the Shangri-La Dialogue, the Asian security conference held in Singapore, the confrontation between the United States and China came into focus again.

The biggest themes were:

• The Taiwan Strait situation
• The South China Sea issue
• Semiconductor supply chains
• Managing military tensions

The U.S. side emphasized the importance of maintaining peace in the Taiwan Strait, while China strongly criticized interference in its internal affairs.

Economic Impact

The Taiwan issue is not only a security issue.

Taiwan is home to TSMC, one of the world’s largest semiconductor foundries. If a military conflict occurs, industries such as:

• AI
• Automobiles
• Smartphones
• Cloud services

could suffer serious damage.

In markets, Taiwan contingency risk remains an important investment theme.

Impact on Japan

Because Japan is close to Taiwan, it would be directly affected in areas such as:

• Energy transportation
• Maritime logistics
• Defense policy

Recent increases in defense spending are also linked to this regional situation.

Social Impact

When security risks rise, they can lead to:

• Lower investment
• Weaker consumption
• Employment anxiety

Younger generations tend to feel greater uncertainty about the future.

Article 2

AI Infrastructure Investment Expands Further

Concerns Also Grow Over Rising Global Electricity Demand

Major global IT companies are further accelerating construction of AI data centers.

Particularly notable are large-scale capital investments by:

• Microsoft
• Google
• Amazon
• Meta

Why Investment Continues

In the generative AI race, the situation remains:

“The companies that secure computing power win.”

As a result, investment is expanding in:

• GPUs
• Data centers
• Power generation facilities
• Optical communications networks

Economic Impact

AI investment is currently giving a major boost to:

• Semiconductor markets
• Construction
• Power industries
• Telecommunications

It has become one of the biggest drivers of global economic growth in 2026.

Social Impact

However, there are also challenges.

AI infrastructure consumes enormous amounts of electricity, raising concerns over:

• Higher electricity prices
• Water shortages
• Increased environmental burden

Impact on Japan

Japanese companies are benefiting significantly in:

• Semiconductor materials
• Manufacturing equipment
• High-performance components

At the same time, strengthening domestic power supply systems has become an urgent task.

Article 3

The Ukraine War Enters a New Phase

Ceasefire Prospects Remain Unclear as Russian Offensive Continues

Intense fighting continues in eastern and southern Ukraine.

The Ukrainian government has warned that Russian forces are preparing a new offensive.

Economic Impact

The prolonged war continues to affect:

Crude Oil Prices Rise Again

Continued Caution Over the Middle East Situation

Crude oil prices continued to rise in markets.

The background includes:

• The Iran situation

They may also affect central banks’ rate-cut plans.

Impact on Japan

In Japan, this affects:

• Electricity bills
• Food logistics costs

In rural areas especially, where dependence on cars is high, the burden on households becomes heavier.

Social Impact

Higher energy prices place a larger burden on low-income groups and may widen social inequality.

Article 5

Concerns Grow Over Europe’s Economic Slowdown

German Manufacturing Remains Weak

In Germany, Europe’s largest economy, the recovery in manufacturing remains slow.

The background includes:

• Persistently high energy prices
• Slower Chinese demand
• High interest rates

Economic Impact

If Germany’s economy remains weak, overall EU growth will also decline.

This is also an important risk factor for the global economy.

Impact on Japan

Europe is an important market for Japanese companies.

Exports in areas such as:

• Automobiles
• Machine tools
• Chemical products

may be affected.

Social Impact

In Europe, dissatisfaction is growing over:

• Youth unemployment
• Housing problems
• Rising living costs

This may encourage political change.

Article 6

Extreme Weather Risks Expand Due to Climate Change

Warnings Over Heat and Heavy Rain Around the World

Meteorological agencies in various countries are warning that the risk of extreme heat and heavy rain will rise toward the second half of 2026.

Economic Impact
