Why Grids, Governments and Bond Markets Are Discovering the Same Problem

Markets are moving from rewarding promised capacity to pricing what can actually be delivered when systems are under stress.

• China’s 2030 plan targets more than 2,800 GW of wind and solar, but planners reportedly expect these sources to provide only about 8% of their capacity during peak-stress periods; Australia’s planned 40 GW of new capacity could therefore translate into roughly 4 GW of dependable power under adverse assumptions.
• France’s 10-year spread over Germany widened from about 55 basis points in February to roughly 147 basis points by 5 October, while French debt reached about 119% of GDP, the 2026 deficit about 5.4%, and 10-year yields approached 5%.
• US marketable Treasuries stood at approximately US$32 trillion at the end of September, with about US$2.1 trillion of net issuance expected in 2026; short-term bills represented roughly 50% of issuance versus a historical norm near 20%.
• A 1 percentage-point rise in the average Treasury rate would eventually add around US$310 billion in annual interest costs, while interest already absorbs about 21% of federal revenue and total debt service is roughly 200% of revenue including principal.
• Hyperscaler bond issuance reached about US$220 billion in the first half of 2026, versus roughly US$108 billion in all of 2025, as AI infrastructure competes with governments for capital and raises the financing burden on the sector.

Takeaway: Investors should favour cash-generative businesses and scarce, dependable assets, remain cautious on highly leveraged growth and long-duration government bonds, and avoid treating the analysis as a forecast of an imminent crisis because productivity gains, policy intervention and cheaper storage could delay or reverse the adjustment.
