Teen social media ban spreads around the globe

In December, Australia became the first major economy to ban teenagers from accessing social media platforms. The policy has initially been met with some scepticism and concerns about enforcement. However, if it produces clear benefits, then other countries could quickly follow suit.

One potential scenario is that Australian teenagers change their behaviour faster than expected. This could see young people spending more time outdoors, increased participation in organised sport and clubs and a substantial increase in demand for leisure and fitness activities. If this happens, we could see a domino effect, with governments around the globe recognising the benefits and introducing similar measures.

For financial markets, the implications would be significant. Expectations for long-term user growth and advertising revenues at major social media platforms could be revised lower.

At the same time, investors would be likely to move capital into sectors aligned with physical activity. Leisure, sporting goods, outdoor clothing and fitness-related businesses could all benefit, reinforcing a shift towards a more diversified and balanced equity market.

China invades Taiwan

The Chinese army, navy and air force launched large-scale military exercises around Taiwan shortly before the New Year, rehearsing seizing or blockading the island.

The drills came only 11 days after the US announced the sale of weapons systems worth £8.2 billion to Taiwan, which is reinforcing its defences against China. The Beijing government regards the island as Chinese territory and is committed to ‘reunification’.

A Chinese invasion or any significant further escalation of military action would have a global economic impact. Taiwan produces over 60% of the world’s semiconductors, including more than 90% of advanced chips vital for the technology, automotive and defence industries. Any disruption would trigger severe shortages, driving costs higher and fuelling global inflation.

Western nations would be likely to impose sweeping sanctions on China, prompting retaliation and accelerating trade fragmentation. Japan has signalled it would back Taiwan militarily, which could draw the US into the conflict.

Financial markets would be likely to react sharply, with global equities tumbling, while safe-haven assets such as the US dollar, gold and Treasuries surge.

Global breakthrough in nuclear fusion

More than 50 companies worldwide are pushing to overcome considerable technical obstacles to create the first commercially viable nuclear fusion reactor, which is a technology long hailed as the ‘holy grail’ of clean energy.

One contender is a group combining the Trump family’s media group and Google-backed fusion energy company TAE Technologies. The group plans to start work this year building what it claims will be the world’s first ‘utility-scale’ nuclear fusion power plant.

Unlike traditional nuclear fission, fusion generates minimal waste and zero carbon emissions, delivering almost limitless power from abundant resources like hydrogen. This breakthrough could revolutionise the global energy system, slashing dependence on fossil fuels and reshaping industrial and geopolitical dynamics.

Energy costs would fall sharply, lifting productivity and easing inflationary pressures worldwide. Economies reliant on oil and gas exports would face structural decline, while the renewable energy, electrification and infrastructure sectors would be likely to surge.

For investors, the implications are profound. Shares in traditional energy giants could see sharp falls, while companies in advanced materials, grid technology and clean-energy infrastructure would stand to benefit significantly.

Japan embraces ‘Sanaeonomics’

Shortly after her election last year, Japan’s Prime Minister Sanae Takaichi unveiled a £100 billion stimulus package. After decades of cautious policymaking, she may have the ambition to maintain this momentum through ‘Sanaeonomics’ – a turbocharged, unapologetically bold successor to Abenomics.

Channelling the conviction of her political idol, Margaret Thatcher, Takaichi could potentially drive through sweeping pro-growth reforms with a speed and clarity Japan has not seen in a generation. This would be likely to see corporate governance improved, productivity incentives unleashed and the long-discussed restructuring of Japan’s companies and economy finally become a reality.

As the economic transformation gathers pace, the Bank of Japan begins a meaningful normalisation of interest rates. Real yields turn positive, confidence spikes and the enormous yen carry trade hits the buffers. This trade has been one of the defining flows of the past decade, with investors borrowing in yen at very low interest rates and investing this cash in growth assets elsewhere in the world. If these positions were rapidly unwound, it would be likely to drive the yen sharply higher and unleash a torrent of capital back into Japanese markets.

Winners would be likely to include Japanese equities and unhedged yen holders. Losers could include carry trade borrowers and exporters reliant on a weak yen.

Should this scenario become a reality, Japan – long dismissed as a value trap – could become the most exciting story in global markets.
