US Treasury yields increased during the week of March 13, 2026, after oil prices briefly exceeded $100 per barrel, prompting investors to delay expectations for Federal Reserve rate cuts into later 2026. Markets now price in only one rate cut for the year, down from prior forecasts, as February CPI data appears outdated amid March's energy inflation spike. The bond market showed unhinged behavior amid fears of higher headline inflation, slower growth, and stagflation risks from sustained high oil prices. A prolonged oil elevation could pair high inflation with unemployment rises, complicating Fed policy.
