MAB · 84/100 — La note Magna est notre composite 0–100 de la puissance nationale structurelle — cinq dimensions, plus de 100 indicateurs. C'est l'évaluation propre du Bureau, pas un miroir des chiffres de la Banque mondiale ou de la CIA.
Momentum +6 — Momentum trimestriel : la lecture du Bureau sur la trajectoire du pays au dernier trimestre, de −10 (dégradation rapide) à +10 (accélération).
Fin septembre a concentré le signal du trimestre : le sommet Trump–Xi a apporté des baisses de tarifs réciproques et une trêve commerciale jusqu'en janvier 2027, tandis que l'annonce de l'aciérie Mesabi à 15 milliards de dollars a confirmé le pari industriel.
L'autre face de la même lame : l'escalade tarifaire contre le Canada montre que le réflexe protectionniste reste intact — le momentum est positif, mais payé en frictions.
