Correction and editorial revision — 23 October 2026: This retrospective replaces the earlier mixed-time narrative with dated provider observations. The earlier supply-shock and Fed-policy interpretation exceeded the price evidence retained for this article. The earlier causal explanations and trading implications are withdrawn; their removal is not a finding that every cited event was false. The original input file is unavailable. The cutoff below is the calendar day before the original publication date, selected for this reconstruction; it is not a claim about what was known when the original article was written.
This archive review uses observations available in the retrieved daily history on or before 2026-04-06. Each market has its own closing time. The question is: Does an Oil Spike Establish a Fed Policy Shift?
The measured comparison
WTI futures moved from $111.54 on 2026-04-02 to $112.41 on 2026-04-06: +0.78%, or $+0.87 per barrel in the quoted series. The five-interval change from 2026-03-27 was +12.82%. WTI futures history.
The US 10-year yield proxy changed +2.2 basis points over 2026-04-02–2026-04-06, while gold futures changed +0.11% over 2026-04-02–2026-04-06. These observations do not quantify lost production, shipping capacity or an inflation pass-through. An oil-price change cannot on its own separate a supply effect, a demand effect and futures-contract effects.
Reproducing the longer comparison
For WTI futures, the five-interval baseline is 99.64 on 2026-03-27; the endpoint is 112.41 on 2026-04-06. The calculation is (endpoint ÷ baseline − 1) × 100 = +12.82%. This uses the endpoints directly rather than adding rounded daily percentages. Five observations need not correspond to one calendar week when a market is closed.

Scope and limitations
Returns are calculated before rounding from Yahoo Finance daily history, not independently verified exchange settlement records. Index values are in points; the yield proxy is quoted in percent; currency quotes are local units per US dollar; gold and WTI futures are dollars per ounce and barrel. Futures-series changes can reflect contract rolls and are not a continuously held contract’s investment return. These are retrospective observations, not live prices or a reconstruction of every intraday quote available to the original author.
