2026-08-13 Review: Did Lower Yields Establish Rate-Cut Expectations?

Correction and editorial revision — 23 October 2026: This retrospective replaces the earlier mixed-time narrative with dated provider observations. The original article treated a nominal yield move as proof of expected policy changes. The earlier causal explanations and trading implications are withdrawn; their removal is not a finding that every cited event was false. Historical closing observations can differ from the intraday quotes used in the earlier version.

This archive review uses observations available in the retrieved daily history on or before 2026-08-13. Each market has its own closing time. The question is: Did Lower Yields Establish Rate-Cut Expectations?

What changed in the calculation

• For KOSPI, the archived input reported +7.37%. Matching its quoted value to 2026-08-13 and comparing with 2026-08-12 gives +3.56% in the provider daily series.
• For US 10-year yield proxy, the archived input reported -0.79%. Matching its quoted value to 2026-08-13 and comparing with 2026-08-12 gives -0.88% in the provider daily series.

The comparison above concerns the archived input and dated daily history. The table below uses a single stated cutoff with each instrument’s own preceding observation; it does not assert simultaneous prices. For the yield proxy, percentage changes in the quote are distinct from basis-point changes and from bond returns.

The measured comparison

The US 10-year yield proxy moved from 4.682% on 2026-08-12 to 4.641% on 2026-08-13. The difference is -0.041 percentage points, or -4.1 basis points. Dividing the change by the earlier yield instead gives -0.88%; that relative change in a yield quote is not a bond investment return. US 10-year yield proxy history.

From 2026-08-06 to 2026-08-13, the proxy changed -2.9 basis points. The daily change is only one part of that interval. The Nasdaq’s latest daily return was +0.81%, and its five-interval return was +1.73%. These measurements do not decompose expected policy rates, inflation expectations, real yields or the term premium. A nominal yield series cannot stand in for all four.

Reproducing the longer comparison

The five-interval baseline is 4.670% on 2026-08-06; the endpoint is 4.641% on 2026-08-13. Subtract the baseline from the endpoint and multiply by 100 to obtain -2.9 basis points. No compounding is needed to express the difference between two yield levels.

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.
