(Bloomberg) -- Spiking energy prices, more US tariffs and mushrooming spending on artificial intelligence are reawakening investors' inflation fears. Most Read from BloombergA week that began with spiraling violence in the Middle East has culminated in oil breaking through $100 a barrel, which will lift costs along global supply chains.

No immediate interest-rate moves are currently anticipated, but a summer of inflation angst is now looking likely to persist in financial markets. Surging global bond yields are just one symptom of the alarm among investors that consumer prices risk getting out of control.
