How the Trackers Compare
The differences between providers are small. StatMuse’s monthly summary shows an open of $115,738.96 and a close of $108,236.71. Trader Villa’s Binance data shows an open of $115,764.07 and a close of $108,246.35. Best Crypto Checker shows a start of $115,697.30 and an end of $108,208.40. These variations reflect different venues and sampling methods, and they explain why monthly summaries can differ by a few basis points.
The Dollar Side of the Story
The clearest August 2025 dollar-index datapoint comes from PNC’s August 2025 Currency Review, which said the U.S. dollar index weakened 0.28% in the trailing quarter.
Barchart’s performance report shows a longer window: DXY was up 2.49 points (+2.52%) since 29 July 2025, with a 52-week low of 95.55 on 27 January 2026 and a 52-week high of 101.80 on 24 June 2026. That is not an August-only figure, but it is the closest dated DXY series among the cited sources.
What the Evidence Does and Doesn’t Show
None of the cited Bitcoin trackers connects the monthly decline to the dollar index. They report prices, not causation. PNC’s currency review covers the dollar, but it does not mention Bitcoin. As a result, there is no public quantitative study in the sources reviewed here that directly attributes or measures the impact of DXY movements on Bitcoin prices specifically for August 2025.
What the evidence does show is that Bitcoin fell about 6.5% in August 2025 while the dollar index weakened 0.28% on a trailing-quarter basis. That is a snapshot, not proof of an inverse relationship.
Key Takeaways
- Bitcoin fell about 6.5% in August 2025, closing near $108,236.71.
- The U.S. dollar index weakened 0.28% in the trailing quarter, according to PNC’s August 2025 review.
- No cited source quantifies DXY’s impact on Bitcoin for that month.
The Bottom Line
The August 2025 record is clear on price: Bitcoin declined about 6.5%, with trackers clustered near $108,236.71. The dollar side is thinner. PNC’s review shows the index down 0.28% over the trailing quarter, and Barchart’s 52-week report shows it higher since 29 July 2025. Readers should be cautious about claims that quantify DXY’s impact on Bitcoin for that specific month, because the cited sources do not support one.
