BlackRock’s IBIT sees $144M in net outflows as bitcoin ETFs drop
BlackRock’s IBIT just experienced $144 million in net outflows, and it’s largely tied to the rising Treasury yields. Investors are pulling back from riskier assets, including bitcoin ETFs, which is shifting the market dynamics a bit.
This trend reflects a broader caution in the market, as higher yields often lead investors to seek safer, more stable options. It’s interesting to see how quickly sentiment can change when macroeconomic factors come into play.
Keep an eye on how this might affect overall bitcoin positioning in the coming weeks. For listeners who want low-fee crypto exposure, our markets partner Kraken supports BTC — link in show notes.
The Fed raised interest rates by a quarter point, the first hike since 2023, yet Bitcoin climbed to around $76,138. This move defies the usual expectation that tighter policy crushes risk assets. Traders had already positioned themselves ahead of the announcement, with a 92.7% chance of a hike priced in. The immediate reaction saw Bitcoin dip to $75,350 before bouncing back sharply.
Interestingly, historical patterns show traders often adjust their positions pre-announcement, leading to less volatility after the news drops. Some analysts suggest that a single hike could actually calm long-term yields instead of spooking the market, especially since the Fed's statement was measured and unanimous.
While Bitcoin and XRP faced pressure from the failed CLARITY Act in the Senate, which wiped out over $300 million in leveraged positions, not all altcoins followed the same path. Zcash, for example, saw a notable rally. With 16 Fed officials anticipating another rate hike this year, the focus may shift to whether the CLARITY Act debate will reignite before the next Fed meeting.

Ethereum’s client diversity picture fractures under incompatible estimates
Ethereum's client diversity is showing some cracks, with a recent snapshot revealing conflicting estimates on client shares. Teku was pegged at 99.83% by one source, while another had Lighthouse at 51.32%. This inconsistency raises concerns about the safety of the network, as a bug affecting a client with over 33% of nodes could halt transactions, or worse, lead to incorrect chain finalization.
Researchers are exploring ways to enhance validator privacy, including daily key changes and zero-knowledge proofs to obscure links between validator activities. However, these measures could complicate how we assess client and operator concentration. The push for privacy must also consider the need for accurate measurement systems to maintain Ethereum's safety protocols.

Bitcoin absorbs Fed rate hike as officials see more tightening
Bitcoin's price action has been pretty steady, even as the Fed raised rates. In the derivatives market, we saw about $82 million in net selling for Bitcoin and $68 million for Ether, but on the spot side, Bitcoin managed to pull in around $15.5 million in net buying. That suggests there’s some solid demand holding up against the selling pressure from derivatives.
Interestingly, there was a notable shift in Bitcoin exchange flows post-rate hike, with around 2,170 Bitcoin moving onto exchanges, followed by 1,260 being withdrawn. It seems like investors are recalibrating rather than just pulling back entirely. The focus now is whether this demand can sustain itself as we look ahead to more potential tightening from the Fed.

Analyst Says This Setup Could Send Bitcoin Above $90K by November
Bitcoin's sitting at around $76,000, and analyst Matthew Hyland thinks it could push above $90,000 by early November. He sees a bullish divergence forming, suggesting a potential reversal despite the market's bearish sentiment. Hyland believes this could be a daily cycle low, even as some analysts are calling for a drop to the $70,000-$72,000 range.
Interestingly, while some traders are feeling the pressure, others are pointing to a significant increase in Bitcoin holdings over the last year as a bullish indicator. The recent drop followed the Senate's failure to advance the CLARITY Act, which led to a notable capitulation event among short-term holders.

What Happens to Ethereum Price Now That the Clarity Act Has Failed
Ethereum (ETH) and the wider crypto market felt the impact of the Clarity Act failing to clear the Senate. Analysts had touted the bill as a major tailwind for the second-largest cryptocurrency. Expectations that its advance would trigger a rally have now been reset. The setback has left its mark on ETH. Over the past week, Ethereum price dropped around 3%. The altcoin dipped to $2,388 after the CLARITY Act failed, then rebounded to $2,400 shortly after. In comparison, other major altcoins like XRP and Hyperliquid have dropped over 8%. US-listed spot Ethereum funds also saw heavy selling.
Circle opens Arc mainnet as it seeks an edge for USDC utility
Circle's Arc mainnet launches on September 16, allowing USDC to handle both payments and transaction fees from the same balance. This could streamline stablecoin usage and potentially increase USDC demand as it competes with Tether. The public rollout follows a private network that had over 100 builders engaged last month.
Arc is a layer-1 blockchain designed for stablecoin transactions, ensuring payments finalize in under a second. Users can send and pay fees with USDC without needing a separate token, simplifying the process. This could enhance user experience and encourage businesses to adopt USDC for both payments and settlements.
The validator set includes major players like BlackRock and Visa, which adds institutional credibility. However, while Arc aims to boost USDC's utility, the real test will be whether it attracts new users and funds. The launch alone won’t guarantee market share growth; it’s about whether easier transactions lead to more USDC adoption.

US lawmakers advance bill to lock Trump’s Bitcoin reserve into law
The legislation would effectively codify Trump’s Bitcoin reserve policy, locking up Bitcoin acquired through civil and criminal forfeiture for 20 years. US lawmakers took a step on Wednesday to put US President Donald Trump’s executive order to establish a strategic Bitcoin reserve into law. The American Reserve Modernization Act of 2026 (H.R. 8957) passed the US House Committee on Financial Services in a 28-21 vote.
