What's happening
The Iran conflict has triggered a sharp repricing across global fixed-income markets, with investors fleeing government bonds in response to surging energy costs and renewed inflationThe rate at which prices rise across an economy. fears. Treasury yields, gilts, and Japanese government bonds all climbed to multi-year highs this week, erasing months of disinflationary momentumThe empirical fact that winners keep winning over the medium term..

After spending time with leaders across Asia and China, Ray Dalio says the perception of American power is shifting fast.
