Bitcoin broke above $86,000 and reached its highest levels since late January, pushing the total crypto market capitalization back above $3 trillion. The rally was powered mostly by nearly $1 billion of inflows into US spot bitcoin ETFs — a record daily figure since October 2025 — with additional support from a short squeeze, record highs in Nasdaq and lower oil prices on hopes of a deal with Iran. The fear and greed index hit 79, and altcoins outperformed BTC: Bitcoin Cash jumped 20–27% after CME announced its futures, memecoins posted double-digit gains and Zcash led the rally. The day was just as busy on the corporate and regulatory front — from Binance's stake in Circle to fresh federal investigations and European central banks' proposals on stablecoins.
Bitcoin breaks out: highest level since late January
BTC exited its narrow range, clearing resistance near $86,500 and touching $87,350 — the highest since January 29 — after gaining roughly 12–13% in a week. The move was supported by risk appetite at record-high Nasdaq, a short squeeze and lower oil: WTI fell to $89.16 a barrel, the lowest since September 4, after Donald Trump said a deal with Iran is possible after November's elections.
Technical indicators point to a change in sentiment. Glassnode recorded the MVRV index crossing its 365-day moving average — the same pattern that preceded the bull markets of 2019 and 2023. According to CryptoQuant, BTC traded back above the 365-day moving average for the first time since March 2023, and long-term holders appear to have finished selling. The rally was also supported by the US Treasury's statement that it will at least double its liquidity-support operations. A reminder of the macro backdrop: on September 16, the Fed raised rates by 25 basis points to 3.75%–4%, the first hike since 2023.
Spot bitcoin ETFs attract nearly $1 billion in a single day
On Monday, US spot bitcoin ETFs posted $998.95 million in net inflows — the biggest daily total since October 2025. The leaders were IBIT ($381.37 million), ARKB ($289.12 million) and FBTC ($238.84 million), with MSBT and BITB also in positive territory. Cumulative net inflows since launch stand at $56.16 billion, and the funds hold $110.14 billion in BTC, about 6.30% of the market cap. According to Bitcoin Magazine and Decrypt, the key effect: BTC climbed above the estimated average ETF holder cost basis of $81,722, putting the average fund buyer back into profit for the first time since January.
The contrast with the previous week is telling: in the week to September 18, inflows were the lowest in history at just $6.2 million. The Glassnode Altcoin Cycle Signal, meanwhile, reached 81.25 out of 100, pointing to altseason, with BTC dominance stuck at 59.7%. Combined altcoin capitalization hit $1.19 trillion — the highest since late January, up 33% since August 19 — and ETH ETFs took in $270 million on the same day, also the biggest inflow since October 2025.
Binance: a $100 million stake in Circle and an Iran-related investigation
The largest crypto exchange found itself at the center of two major stories. Circle sold Binance 1,237,011 Class A shares at $80.84 apiece in a private placement that closed on September 17 — roughly $100 million and a discount of about 5% to the market price. In parallel, the two sides signed a five-year commercial agreement under which Circle pays Binance a monthly bonus tied to USDC volume processed through the Modular Smart Contract Wallet infrastructure. Binance cannot sell, transfer or hedge the shares for up to two years, but keeps voting rights; the deal replaces prior agreements from November 2024 and August 2025. The transaction makes the exchange a shareholder in the main rival to Tether's stablecoin issuer and strengthens USDC distribution on the largest trading venue; CRCL rose more than 1.3% in pre-market trading. CoinDesk
At the same time, Bloomberg reported that the US Attorney's Office in Manhattan and the DOJ's criminal division are looking into whether Binance knowingly allowed trading that violated US sanctions against Iran. Binance says it has a zero-tolerance policy toward sanctions violations and cooperates with law enforcement. The investigation follows DOJ actions to confiscate $61 million from Iranian oil sales that authorities say were laundered through Binance. The exchange previously pleaded guilty and paid $4.3 billion over violations of banking and sanctions laws; WSJ, NYT and Forbes have written that two Chinese companies moved billions of dollars through Binance in an Iran oil sanctions-evasion scheme — Binance has called those reports defamation.

ECB proposes expanding the stablecoin yield ban
The European System of Central Banks (ESCB) submitted a 57-page response to the European Commission's consultation on the MiCA review, which closes September 30. The central banks call for extending the ban on stablecoin yields to crypto lending, borrowing, staking and other stacked yield schemes, and for replacing the 30–60% bank-deposit reserve requirement with liquidity thresholds at one- and five-business-day maturities (under EBA standards — 40% within one day and 60% within five days for significant stablecoins). The ESCB warns that large redemptions could transfer stress from stablecoins to commercial banks. CoinDesk
The position could substantially limit stablecoin yields in the EU — including USDT and USDC; it was precisely a similar provision that led Tether to abandon its EU license earlier, and Tether CEO Paolo Ardoino flagged the point as a source of systemic risk back in 2024.
Stablecoins enter payment infrastructure
SoFi Bank and Mastercard announced that SoFi's card program, with an expected annual volume of more than $25 billion, now settles in the SoFiUSD stablecoin on Mastercard's global payment network. SoFiUSD is issued by SoFi Bank N.A. — a national bank under the OCC — and redeemable 1:1 for dollars (not FDIC-insured). It is the first time a stablecoin issued by a national bank is used for settlement over Mastercard's network. Merchants can receive USD payouts through Big Business Banking without holding stablecoins, and Galileo plans to offer SoFiUSD settlement options to card clients and issuing banks. Crypto.News
BVNK, the payment company Mastercard acquired for up to $1.8 billion, added native Stellar support to its stablecoin payments platform across more than 130 markets, for payments, payouts, remittances and treasury transfers. After the announcement, XLM rose roughly 2–2.7% to $0.2135–0.2141. Circle, meanwhile, enabled institutional clients to use BTC as collateral via the cirBTC token and borrow USDC on connected lending markets without selling bitcoin: the model launches through Arc and Ethereum, with Morpho as the first lending market.
The day also served as a reminder of local liquidity risks: Ethena's USDe stablecoin briefly dropped to $0.9202 on the USDE/USDT pair on Binance around 13:00 before recovering to parity; on Bitget the market only dipped to about 0.997 USDT. No causal link to a Binance maintenance window has been established.
Banks and institutions: tokenization on all fronts
Canada's six largest banks — BMO, CIBC, National Bank of Canada, RBC, Scotiabank and TD Bank — joined forces in a project to develop an interbank system of tokenized Canadian-dollar deposits, with other banks able to join. The first phase covers transfers of tokenized deposits between participants, following OSFI's September 10 clarification that tokenized deposits are legally no different from traditional ones. CoinDesk
The European Central Bank announced plans to invest a small portion of its own funds — from its non-monetary-policy portfolio — in tokenized euro-area government securities, settling in central bank money through the new Pontes DLT settlement system launched on Monday. Cointelegraph
RWA integration into the crypto ecosystem also continued. NEAR added access to 20 tokenized Ondo Finance assets — including Tesla, Nvidia, Apple, Microsoft, Amazon and QQQ — through near.com and NEAR Intents, payable in USDC and bitcoin without a separate brokerage account; the product is not available to US residents or in Canada. Coinbase launched fixed-rate USDC loans backed by cbBTC via Morpho Midnight on Base. Crypto lender Arch Lending said it plans to move into loans collateralized by tokenized stocks. And Prometheum's pilot detailed how investors would hold tokenized US stocks: Cede & Co. remains the registered owner of the underlying shares in DTC, with clients receiving securities rights under UCC Article 8.
CME to add BCH and UNI futures; ETPs expand beyond the majors
CME Group announced the listing of standard and micro futures on Bitcoin Cash and Uniswap on October 19 (pending regulatory review): the 250/25 BCH and 10,000/1,000 UNI contracts will become the exchange's 10th and 11th single-asset crypto futures — seven of the eleven were added this year. On the news, BCH jumped to $319.05 (+19.31%) with an intraday high of $324.99, while UNI rose to $9.62 (+7.04%). The expansion of regulated CME futures legitimizes BCH and UNI as institutional assets. Decrypt
The altcoin ETP lineup is growing too: 21Shares listed physically backed ETPs on Zcash and ether.fi on Euronext Paris and Amsterdam with a 2.5% annual fee, following the launch of Grayscale's Zcash product in the US. Privacy coins keep leading the move: the sector grew nearly fivefold in a year — from $6.2 billion to roughly $30 billion by 21Shares' estimate (CoinGecko values the category at about $36.9 billion), and ZEC is up nearly 1,100% over the year at above $1,500.

The US regulatory agenda: crypto after the CLARITY Act failure
Senator Cynthia Lummis publicly commented on the failed procedural vote on the CLARITY Act, saying Democrats chose "visceral hatred" of Donald Trump over good policy: every Democrat and three Republicans voted against advancing the bill. House Financial Services Chairman French Hill noted that Trump's meme coin had "poisoned the well" of debate. The crypto PAC Fairshake, backed by Coinbase and Ripple, is preparing $30 million to oppose former Senator Sherrod Brown in the Ohio Senate race — the biggest planned spend of the cycle — and crypto companies have contributed $206 million to the 2026 US election cycle overall, mainly through Fairshake. CoinDesk, Cointelegraph
The White House, meanwhile, says crypto market structure cannot wait for another attempt at the CLARITY Act: regulators are taking the initiative — crypto advisor Patrick Witt pointed to recent SEC and CFTC progress, while Treasury and bank regulators are working on GENIUS Act implementation rules on schedule. Franklin Crypto chief Chris Perkins argues the industry got its "rulebook" without Congress: two days after the vote, the SEC issued a five-year innovation exemption for tokenized-stock venues, and the CFTC said it would write its own rules if Congress doesn't. a16z and the DeFi Education Fund, in turn, asked the SEC for a safe harbor with a rebuttable presumption that DEX protocols and their frontends are not exchanges under the Exchange Act; a16z also proposed a registration regime for centralized crypto platforms modeled on the 1998 ATS rules.

Beyond the US: South Korea's FSC confirmed the Digital Asset Framework Act will go to the National Assembly subcommittee in November and plans to finish the second stage of stablecoin rules in 2026. In Russia, Prime Minister Mikhail Mishustin said the digital ruble is available for transactions nationwide since September 1; crypto payments have been banned there since 2022, and retail crypto investments are capped at 300,000 rubles a year.
Security: iOS threats and the Coldcard recovery
SlowMist warned that FomoPeek — an app available in the official App Store from September 9 to 17 and promoted via crypto opinion leaders — contained malicious modules capable of stealing seed phrases and private keys. In parallel, Google Threat Intelligence described a multi-stage DarkSword attack exploiting WebKit/JavaScriptCore vulnerabilities to gain access to iPhones and steal crypto wallet data; confirmed attacks targeted iOS 18.4–18.7 since November 2025. SlowMist advises treating seed phrases, private keys and sensitive data as compromised even after deleting the app. Protos
White-hat hackers, meanwhile, moved 52.37 BTC (over $4.5 million) from wallets affected by the Coldcard exploit to the Crypto Recovery Trust — a Wyoming trust set up to return funds to victims — roughly 2.8% of at-risk volume per Galaxy Digital. The root cause was a bug in Coldcard's firmware seed generation from March 2021; about 1,830 BTC (~$157 million) sit across 9,162 addresses. Decrypt
Exchanges and infrastructure
BitMEX is shutting down after 11 years: exchange operations cease on September 23 at 04:00 UTC, open positions will be forcibly closed, and withdrawals remain available. BitMEX failed to find a buyer after attempts to sell at a valuation of around $1 billion. CoinGape
Kalshi denied wash-trading allegations: a CoinDesk analysis found BTC and ETH perpetual volumes on the platform dominated by repetitive fixed-size trades — orders near $5,499 made up 57% of ETH perpetual volume on September 17–20. Kalshi says the trades came from a single market maker it pays to maintain orders. The platform also filed with the CFTC to launch margin trading on event contracts for qualified participants. CoinDesk
X added a "Trade" button to crypto cashtags for US users, routing to Coinbase, Kraken, Gemini, Interactive Brokers and Moomoo. On the news, DOGE hit an intraday high of $0.1059 — its highest since June. Coinbase, for its part, is opening US retail access to IPO allocations in its app, starting with the Oura IPO (allocations are managed by Coinbase Capital Markets via Apex Clearing).
Strategy bought back 5,553 of the 6,948 BTC it sold over the summer: it spent $445.4 million versus the $345.1 million raised from the sale — an opportunity cost of more than $100 million. Four long-dormant bitcoin wallets moved a combined 1,971.03 BTC (~$161 million) between September 6 and 22, including coins untouched since 2012 and 2016. Protos
Other events of the day
Avalanche activated the Helicon upgrade: the minimum staking period dropped from two weeks to 48 hours, uptime requirements tightened (90%) and a dynamic minimum gas fee was introduced. Pi Network lifted a KYC barrier for more than 417,000 Pioneers and is preparing a gas-fee fix for roughly 497,000 wallets. Prediction market Trueo is making Ethereum mainnet its primary deployment; Vitalik Buterin called the project "ethical," and the TRUE token rose about 900% in 24 hours. Cardano joined the x402 standard for AI-agent payments. Trader Peter Brandt published an XRP target of $5.40 and an ETH potential of up to $8,600 (after clearing $5,000) — an analyst's forecast rather than a confirmed event. Lido DAO approved an infrastructure update including an execution delegation framework and new deposit reserve controls.
Finally, the industry is pouring money into politics: crypto firms contributed $206 million to the 2026 US election cycle, and market-adjacent sectors drew attention too — Bernstein raised its prediction-market volume forecast to $10 trillion a year by 2035. The AI market moved as well: Anthropic released Claude Opus 5.5 at lower prices, and OpenAI responded shortly after with GPT-6 Sol and Luna, halving API prices versus GPT-5.6 promo tariffs.
The bottom line: the market is trading on a bullish note with broad participation for the first time in months — bitcoin's reversal is backed by technical indicators, institutional flows are back in the funds, and infrastructure from banks to payment networks keeps moving toward digital assets.
