FRED Shock Summary

The supplied FRED observations show no day-to-day change in the administered-rate configuration but a pronounced increase in broad U.S. economic policy uncertainty alongside a smaller rise in equity-market-related uncertainty. The Interest Rate on Reserve Balances remained at 3.65% on September 5, unchanged from September 4. The federal funds target range was also unchanged, with the lower limit at 3.50% and the upper limit at 3.75%. Taken strictly from these observations, the policy-rate settings represented in the packet were stable across the two dates, with IORB positioned 15 basis points above the lower bound and 10 basis points below the upper bound of the target range.

The largest movement in the supplied data is in the Economic Policy Uncertainty Index for the United States, which increased from 194.77 to 648.29. That is a rise of 453.52 index points, or approximately 232.8% relative to the previous observation. The magnitude of this one-day increase indicates a substantial change in the measured level of policy-related uncertainty captured by this index between September 4 and September 5. The observation itself does not identify the events or information responsible for that movement, so no specific causal explanation can be established from this packet alone.

Equity Market-related Economic Uncertainty also increased, but much less dramatically, moving from 111.16 to 121.57. The 10.41-point increase is approximately 9.4% relative to the previous value. The direction of change therefore aligns with the broader policy-uncertainty measure, while the scale differs sharply. Within this limited snapshot, uncertainty indicators were higher on September 5 even though the supplied administered policy rates were unchanged. The data support describing a divergence between stable rate settings and rising measured uncertainty, but they do not establish that either development caused the other.

Yahoo Shock Summary

The supplied cryptocurrency observations show modest positive moves in both Bitcoin and Ethereum between the completed closes of September 4 and September 5, with Ethereum posting the larger percentage increase. Bitcoin closed at 79,823.87 on September 5, up 151.90 from 79,671.97 on September 4. The reported change of 0.19% indicates that Bitcoin was effectively little changed on a one-day percentage basis despite ending slightly higher.

Ethereum closed at 2,480.74 on September 5, compared with 2,456.08 on September 4. Its increase of 24.66 corresponds to a reported gain of 1.00%, making Ethereum’s move materially larger than Bitcoin’s in percentage terms over the same interval. Ethereum therefore outperformed Bitcoin by roughly 0.81 percentage points on this single-session comparison.

Taken together, the two observations indicate a broadly positive but uneven crypto-market move: both assets advanced, while the strength of the increase was concentrated more in Ethereum than in Bitcoin. The data do not show a broad selloff, nor do they show a large synchronized surge across the two assets. Instead, they describe a relatively stable Bitcoin close accompanied by a more noticeable, though still limited, gain in Ethereum. Because the packet contains only two assets and two consecutive completed closes, it does not establish a sustained trend, a change in market regime, or the cause of the relative performance difference.
