Social media has changed who can give financial advice, but not the forces that shape it. Today’s “finfluencers” can reach millions without a television programme, a radio show or a wealthy clientele. Their best guidance is familiar: build an emergency fund, avoid scams, control expensive debt and invest for the long term. Yet once they move beyond those basics, their advice often reflects the characteristic financial habits of their own countries - sometimes correcting those habits and sometimes reinforcing them.

Kevin Warsh wants to reshape the Federal Reserve, but he is beginning with advice rather than decrees. The new chair has assembled five public task forces to examine how the Fed communicates, manages its balance-sheet, uses alternative data, understands artificial intelligence and diagnoses inflation. The panels bring impressive expertise into the open. Their harder task will be turning divergent views into recommendations that the Fed’s consensus-driven leadership will actually adopt.

China’s economy is weakening at an awkward moment. Its exports still look formidable, but the trade surplus that helped sustain growth may already have peaked. At home, meanwhile, fiscal policy is moving in the wrong direction: tax receipts are rising faster than spending, narrowing the budget deficit when weak demand calls for stimulus. The result is an accidental austerity that exposes the limits of relying on exports and high-tech industry.

Oil markets are sending a misleadingly calm signal. Even after renewed fighting around the Strait of Hormuz, Brent crude remains well below its April peak. Yet the fuels people and businesses actually use - petrol, diesel and jet fuel - are scarce and expensive. The reason is that the global energy shock has shifted from oil wells to refineries: the world has enough crude, but too little capacity to turn it into usable products.

The contest over global finance is shifting from currencies to the infrastructure that moves money. America still dominates that infrastructure through the dollar, its banks and firms such as Visa and Mastercard. Yet governments increasingly see dependence on American payment rails as a strategic vulnerability. Their response is to build national and regional alternatives - a trend that could weaken American financial power while making the global system more costly and fragmented.

Artificial-intelligence sovereignty sounds like national control over models, chips and computing infrastructure. For most countries, that goal is unrealistic. The frontier is increasingly dominated by America and China, whose governments can shape not only how advanced models are made safe, but also who is allowed to use them. The practical challenge for everyone else is therefore to reduce vulnerability without wasting fortunes on an impossible race for total independence.

America’s effort to reduce its dependence on Chinese clean-energy companies is producing an unexpected result: Chinese owners are leaving, but much of their machinery, technical knowledge and supply chain remains. The policy may strengthen American manufacturing, yet it does not automatically create technological independence.

This summary covers The Economist’s July 4th, 2026 Asia article listed in the contents as Subsea data cables and published under the headline The new geography of subsea cables.

The internet may feel weightless, but almost all international traffic still travels through fibre-optic cables on the ocean floor. Artificial intelligence is now changing where those cables go. Big technology companies need direct, high-capacity links between data centres, while governments and operators want routes that avoid politically risky waters. Together, those pressures are pulling Asia’s digital infrastructure away from familiar coastal corridors and across the open Indian and Pacific oceans.

Artificial intelligence is making it easier for people to enter court without hiring a lawyer. That can widen access to a system whose cost and complexity shut many people out. But early evidence suggests that chatbots are also filling courts with fabricated precedents, overconfident claims and far more paperwork. The result is not the disappearance of lawyers so much as a new division of labour between machines that make legal help cheaper and humans who verify what the machines produce.
