With GDP at 0.5% and CPI dropping today — is the stagflation framework actually the right lens for the current US economy?

Yesterday the final Q4 2026 GDP estimate came in at 0.5%, down from the preliminary 0.7% and significantly below the previous quarter's 4.4%.

Today US CPI for March drops. Given six weeks of elevated oil prices from the Iran conflict, expectations are for a notable increase.

My question is whether stagflation is actually the right analytical framework here, or whether there are important distinctions being glossed over.

The classic stagflation framework from the 1970s involved supply-side shocks causing persistent structural inflation alongside demand weakness. The current situation feels somewhat different — the inflation pressure is primarily energy-driven and potentially temporary if the ceasefire holds, while the growth slowdown may reflect pre-existing labor market softness rather than a structural demand collapse.

Does that distinction matter for how central banks should respond? And is there a cleaner framework for distinguishing between a temporary supply-shock-driven inflation-growth tension versus a genuine stagflation dynamic?

Also interested in whether the FOMC's stated view — that they'll look through temporary oil-driven price spikes if the conflict de-escalates — represents sound policy or creates risks of its own.
