FRED Shock Summary

The administered-rate configuration was unchanged between September 18 and September 19. IORB remained at 3.90%, while the federal funds target range remained 3.75%-4.00%. IORB therefore sat 15 basis points above the lower bound and 10 basis points below the upper bound, placing it in the upper portion of the 25-basis-point target range. Because all three policy-rate observations were identical across the two dates, this packet records stability in the supplied policy-rate settings rather than a day-to-day change.

The notable movement occurred instead in the two uncertainty measures. The U.S. Economic Policy Uncertainty Index declined from 243.20 to 155.89, a drop of 87.31 index points, or approximately 35.9%. The Equity Market-related Economic Uncertainty Index fell more sharply, from 55.04 to 15.16, a decrease of 39.88 points, or approximately 72.5%. Thus, both supplied uncertainty indicators moved downward on the same date, with the equity-market-related measure showing the larger proportional change.

Taken strictly as a cross-section of these lagged deterministic observations, the packet separates into two patterns: unchanged administered and target rates, and substantially lower daily uncertainty readings. The common direction of the two uncertainty indices strengthens the descriptive observation that measured uncertainty was lower on September 19 than on September 18 across both indicators supplied here. However, a two-day comparison does not establish a persistent trend, and the magnitude of a one-day index movement should not by itself be interpreted as evidence of a lasting change in the underlying policy or market environment. Nothing in the supplied observations establishes a causal connection between the unchanged rate configuration and the declines in the uncertainty indices.

Yahoo Shock Summary

Both supplied crypto assets closed higher on September 19 than on September 18. Bitcoin rose from 80,901.46 to 81,233.68, an increase of 332.22 or 0.41%. Ethereum rose from 2,611.35 to 2,631.96, an increase of about 20.62 or 0.79% using the packet’s reported change. The direction was therefore consistent across the two assets, while Ethereum recorded the larger percentage move.

The relative magnitude is informative descriptively. Ethereum’s reported 0.79% gain was roughly 0.38 percentage points larger than Bitcoin’s 0.41% gain and was about 1.9 times Bitcoin’s percentage increase. Despite that difference in amplitude, neither observation represents a large single-day percentage change in isolation. The main cross-asset signal contained in this limited snapshot is consequently synchronized positive movement rather than divergence: both assets advanced, with Ethereum moving somewhat more strongly in percentage terms.

The observations are limited to two consecutive completed closes for two crypto assets. They establish neither a multi-day trend nor the cause of the shared direction. They also provide no information about intraday paths, trading volume, volatility, positioning, other asset classes, or subsequent prices. Accordingly, the defensible interpretation is narrow: on September 19, both Bitcoin and Ethereum finished above their September 18 closes, and Ethereum exhibited the larger proportional increase. No broader claim about market regime, persistence, or future direction follows from these observations alone.
