Bitcoin ETFs Experience $390 Million Outflow Despite Cooling Inflation

Author: Coinstack

Compiled by Deep潮 TechFlow

Deep潮 Overview: Although cooling inflation data should have been favorable for risk assets, spot Bitcoin ETFs experienced their largest weekly outflow in six weeks, compounded by a sudden delay in the regulatory agenda, signaling a shift in market risk appetite. This week, Trump’s Crypto Summit and the Jackson Hole meeting will become key variables. This article breaks down market conditions through the lenses of fund flows, on-chain data, and narratives.

🗓️ Tuesday, August 18, 2026 | Estimated reading time: 7 minutes

Bitcoin closed on Sunday at approximately $62,800, posting a weekly decline of about 3%, the worst weekly performance in six weeks.

Spot Bitcoin ETFs experienced a net outflow of $389.7 million between August 10 and 14, the largest weekly outflow in six weeks.

The CPI in July rose 0.1% month-over-month and 3.4% year-over-year, in line with market expectations.

The SEC abruptly canceled the vote on the Crypto Regulatory Framework scheduled for August 14, delaying the first formal proposal.

Strategy sold another 1,690 BTC, cashing out $108.6 million, and raised $653 million through new share issuance.

This week’s highlights: Trump Crypto Summit (August 19), FOMC Meeting Minutes (August 20), Jackson Hole Symposium (August 27–29).

This week revealed a disconnect that will impact September’s market dynamics. The July CPI and PPI data, released on Wednesday and Thursday, both came in softer—historically, this would have triggered a Bitcoin rally. Yet the reality was that spot Bitcoin ETFs saw a net outflow of $389.7 million for the week—the largest outflow in six weeks—while BTC declined by approximately 3%. Simultaneously, the CLARITY Act, the Crypto Regulatory Framework, and tokenization exemptions all stalled within the same 72-hour window. Institutional allocators are reducing risk ahead of the Jackson Hole symposium, rather than chasing rate-cut trades based on inflation data.

Here’s what cryptocurrency investors need to understand in the coming week…

Wait for the results next week.

👉 Last week's voting results: Option 3—Regulation (the CLARITY Act)—led with 43.75% of the votes.

Top-performing major coin: Ethereum (down 1.8%)

ETH was the most resilient among major cryptocurrencies this week, closing Sunday at approximately $1,874. Cooler inflation data and lighter selling pressure on ETH ETFs resulted in a relatively shallow pullback compared to the top four cryptocurrencies.

Worst-performing major coin: XRP (down 3.5%)

XRP fell to $0.99, breaking below the $1.00 mark, due to the probability of the CLARITY Act's debate being terminated dropping to 19% and XRP ETF weekly inflows registering only a modest $2.25 million.

This week's market drivers

Soft CPI and PPI data failed to trigger a rebound, as ETFs resumed outflows and the SEC delayed its vote on crypto regulations, continuing the institutional risk-aversion sentiment.

Inflation data came in mild, but spot BTC ETFs still saw net outflows of nearly $390 million.

What happened?

U.S. spot Bitcoin ETFs recorded a net outflow of $389.7 million between August 10 and 14, according to SoSoValue data, marking the largest weekly outflow in six weeks. Ethereum ETFs also saw a modest net outflow of $2.26 million during the same period. In contrast, Solana ETFs experienced a net inflow of $10.26 million, with August 10 posting the largest single-day inflow since May.

Why is it important?

Outflows occurred against the backdrop of moderate inflation data. Following the CPI release, the CME FedWatch tool lowered the probability of a September rate hike to 42%, and yields on U.S. Treasuries across all maturities declined. Nevertheless, investors continued to withdraw funds. As of August 14, the total net asset value of U.S. spot Bitcoin ETFs was approximately $76.6 billion.

Investor Highlights

Monitor whether outflows continue through the Jackson Hole symposium on August 27–29. If Chair Warsh signals a dovish stance, capital flows should reverse quickly. If BTC outflows exceed $200 million for a second consecutive week, it will confirm the start of a broader risk-off cycle.

5.1 July CPI fell to 3.4%, core PPI at 4.2%

What happened?

According to the U.S. Bureau of Labor Statistics report, the CPI rose 0.1% month-over-month and 3.4% year-over-year in July, both in line with market expectations. Core CPI year-over-year declined to 2.5%. Producer prices remained flat, and core PPI rose 4.2% year-over-year, consistent with expectations.

Two consecutive mild data releases strengthened the case for a pause in rate hikes in September, lowering bond yields and supporting risk assets over the medium term.

Both data points were "in line with expectations," not "below expectations." The three FOMC dissenters on July 29 have not softened their public stance, and overall inflation remains stubbornly above the 2% target.

5.2 SEC votes to rescind the Crypto Regulatory Rule

What happened?

The SEC canceled its planned public meeting on August 14 regarding the Crypto Regulatory Framework, its first formal set of rules specifically targeting cryptocurrency. Another tokenization innovation exemption has also been indefinitely postponed.

The proposal has been delayed, not withdrawn. The CFTC’s Innovation Advisory Committee will meet on August 20 to potentially address the regulatory gap for commodity-based cryptocurrencies.

Due to the Clarity Act's cloture vote scheduled for September 15 and its unlikely passage with 60 votes, both legislative and regulatory pathways have stalled within the same two-week period.

5.3 Trump will meet with crypto CEOs at the White House on August 19

What happened?

President Trump is expected to attend a meeting on Wednesday with executives from Coinbase, Ripple, Gemini, Kalshi, Chainlink Labs, and a16z. SEC Chair Atkins, CFTC Chair Selig, Treasury Secretary Bessent, and Commerce Secretary Lutnick are also expected to participate.

This event serves as a precursor to the CFTC’s Innovation Advisory Committee’s first meeting on August 20, signaling the administration’s intent to continue advancing cryptocurrency policy.

Just posturing, no vote. Despite this summit, the probability of the CLARITY Act passing by 2026 on Polymarket remains at 19%.

BTC and stablecoins account for 73% of the top 20 market capitalizations.

According to CoinStats data compiled on August 15, the total market capitalization of the top 20 cryptocurrencies is $2.087 trillion, with Bitcoin accounting for 60.84%, Ethereum for 10.88%, and USDT plus USDC combined at approximately 12.2%.

What does the data indicate?

Nearly three-quarters of the value in the top 20 cryptocurrencies is now concentrated in Bitcoin and USD-pegged stablecoins.

What could this mean?

Capital remains on defense rather than rotating out. Altcoin gains remain narrow and isolated (e.g., Chainlink, Curve, Worldcoin), not broad-based. Mechanically, an altcoin season is unlikely until the share of stablecoins contracts.

Jackson Hole setup

Why is it getting attention?

Federal Reserve Chair Kevin Warsh will deliver his first Jackson Hole speech on August 27–29, following the July 29 meeting, where the Fed held rates steady in a 9–3 vote. Traders are seeking clear signals regarding the September FOMC meeting.

Why it might heat up

Two mild inflation readings and a decline of 23,000 non-farm payroll jobs in July provided cover for Warsh’s shift toward a dovish stance. Historically, crypto markets have typically led Fed pivots by two to six weeks.

Why it might cool down

Since taking office, Walsh has reduced the Fed’s forward guidance, and three hawkish opponents continue to speak out. If he adopts a cautious stance, it could trigger a “sell the fact” reaction.

Solana ETFs are quietly diverging

Last week, the U.S. spot Solana ETF attracted $10.26 million in inflows, while Bitcoin and Ethereum funds experienced outflows. As of August 14, the cumulative net inflow into the SOL ETF reached $1.16 billion.

The first step in Solana's mainnet upgrade on August 17 is reducing the slot time to approximately 350 milliseconds. The market anticipates additional Solana ETF applications. Tokenized equity shares on Solana continue to drive increased real-world usage.

Solana reported a $30.3 million loss in the second quarter due to an SOL write-down. If BTC drops below $60,000, correlation could drag down SOL, even amid inflow narratives.

Understand the divergence in ETF fund flows

When Bitcoin ETFs experience outflows while Solana, XRP, and HYPE ETFs attract inflows, the signal is a rotation, not an exit. For the week ending August 14, three of the six crypto ETF categories tracked by SoSoValue recorded net inflows. The U.S. dollar remains near recent lows.

For serious investors, the pattern is this: under mixed market conditions, when BTC dominance declines, allocators typically rebalance. They shift toward smaller, asymmetric opportunities rather than exiting their crypto exposure entirely. Track SoSoValue’s weekly category snapshots rather than focusing solely on BTC’s headline numbers.

Cboe BZX has applied to list 3x leveraged Bitcoin and Ethereum ETFs, adding leverage to the crowded long positions.

Strategy sold another 1,690 BTC, earning $108.6 million. This is its fourth reduction in 2026.

The total amount stolen due to the Coldcard vulnerability has risen to 1,816 BTC (approximately $116 million). Over 5,200 addresses have been affected.

Circle's Arc mainnet is still scheduled to launch on September 16, with 11 founding validators.

Riot Bitcoin Mining platform signed a 20-year, $9.1 billion lease with a leading cutting-edge AI laboratory at the Rockdale campus.

In mid-August, a rare situation emerged: inflation softened, labor markets weakened further, and regulatory pressure eased—yet risk assets did not rise. This suggests investors are waiting for the Jackson Hole symposium rather than positioning against the trend. If Chair Warsh acknowledges worsening labor conditions, a repricing in September will likely occur ahead of the FOMC meeting.

The next two weeks will test whether Walsh pivots to a dovish stance or holds firm, and whether the CLARITY Act can pass through its September window before the midterm election cycle closes.
