David Sacks Says High Rates Reflect Strong Nominal Growth, Not Just Inflation

David Sacks argues that U.S. interest rates are high largely because the economy is still running hot.
His framework compares interest rates with nominal GDP growth, which he says tend to track each other over time.
David Friedberg pointed out that short-term Treasury yields have risen roughly 60 basis points in about 30 days, increasing pressure on refinancing, auto loans and broader credit conditions.
Sacks identified diesel prices as the main economic drag, arguing that cheaper diesel could reduce inflation and eventually create room for rate cuts.
He also put GDP growth near 3.7%, reinforcing the idea that strong nominal growth can keep rates elevated even if inflation begins to cool.
The bigger takeaway is that the path to lower rates may depend on more than inflation alone.
If growth remains strong, the Fed may have less reason to cut aggressively.
That makes upcoming GDP data just as important as inflation reports when assessing the next move in rates.
