What changed, where the supply base is thin and what to do about it, for a 24-supplier watchlist, from public data every six hours.
Rhine waterway at critically low levels and energy prices elevated; commodity input costs rising sharply across metals and oil.
The Rhine at both Maxau and Kaub is below critical thresholds, historically signalling barge capacity constraints. Simultaneously, EU natural gas is 131% above September 2025 baseline and Brent crude is 37% above its one-year median, while aluminium costs have spiked 23% in the same period. These world-level pressures compound shipping friction and raise input costs for any aluminium-intensive or energy-dependent supply lines.
