“The U.S. Department of the Treasury has announced new rates for Series I bonds.”
SINGLE SOURCE
The web search results contain multiple claims about I bond rates and the Treasury Department, but none of the provided evidence sources confirm the general announcement of 'new rates' in a single, authoritative manner. The sources provide specific, dated rates (e.g., 5.27% or 3.98%) but do not corroborate a general, recent announcement of new rates across multiple independent sources.
