US macro dashboard in one call: Fed funds, CPI, PCE, jobs, GDP, and the Treasury yield curve
The US macro backdrop in one call: the federal funds rate, CPI and PCE inflation, the labor market (unemployment, payrolls, wages), real GDP, and the Treasury yield curve. No ticker needed. Replaces six macro calls (fed-funds + inflation + pce + labor-market + gdp + treasury-yields) at a lower combined price. Spans FRED, BLS, Treasury; sections degrade independently.
