European central bankers have aligned on a contentious issue: justifying the Federal Reserve's $3 billion allocation toward renovating headquarters when estimates suggest the actual cost should fall in the low hundreds of millions.

The math simply doesn't add up. A facility of that scale shouldn't command such an astronomical budget. Yet the Fed has absorbed the expense while simultaneously reporting cumulative losses exceeding $200 billion.

This raises uncomfortable questions about fiscal discipline and resource allocation within the world's most powerful monetary institution. How sustainable is this spending trajectory? What's the actual return on such capital deployment? For those tracking institutional efficiency and monetary policy execution, these numbers warrant serious scrutiny.
