Coinbase-backed advocacy group @standwithcrypto has endorsed 32 bipartisan candidates running for the US House of Representatives who supported the CLARITY Act, as campaigning ramps up ahead of the midterm elections. The endorsements come as the crypto industry channels nearly $200 million into the 2026 election cycle. Senate picks are expected to be announced closer to Election Day.

The US Department of the Treasury has established a QuantumReadiness Task Force to guide the financial sector's shift to post-quantum cryptography. Treasury announced the move on August 24, citing President Trump's Executive Order 14412, signed June 22, which instructs federal agencies to strengthen defenses against advanced cryptographic threats. Treasury said the effort will run through three workstreams: sector alignment, vendor readiness, and risks related to digital assets and emerging technologies. The sector-alignment track aims to coordinate federal agencies, banks, and other financial institutions so migration timelines stay broadly synchronized. Vendor readiness focuses on ensuring encryption providers serving Wall Street deliver quantum-resistant products. The digital-assets track reflects the view that crypto infrastructure faces the same quantum exposure as traditional finance, and potentially greater sensitivity because public-key cryptography underpins blockchain security. Treasury set firm timelines for the migration. Sensitive systems are required to move to post-quantum cryptography by December 31, 2030. Digital signature systems have until December 31, 2031. Treasury Secretary Scott Bessent and Assistant Secretary Luke Pettit are leading the initiative, positioning it as risk-based preparation rather than an emergency response. Treasury said the Task Force is intended to promote "cryptographic agility," enabling organizations to swap encryption algorithms without rebuilding systems from the ground up. Officials highlighted that the immediate concern is not that quantum computers can break today's encryption, but the "harvest now, decrypt later" tactic. Adversaries can collect encrypted financial data, government communications, and corporate information now, store it, and attempt to decrypt it once quantum capabilities mature. Treasury noted that the National Institute of Standards and Technology has already issued post-quantum cryptography standards. The Task Force also aligns with international efforts: in January, the G7 Cyber Expert Group published a roadmap calling for an orderly transition to post-quantum cryptography across global financial systems, and Treasury framed the US initiative as a response consistent with that direction. Digital assets received a dedicated workstream because many blockchains rely on elliptic curve cryptography for transaction signing and wallet security. Treasury warned that a sufficiently capable quantum computer could undermine those algorithms and, in theory, enable forged transactions on networks still using vulnerable cryptography. Treasury's involvement signals regulators are treating the issue as a systemic financial stability risk, with the Task Force focused on broad system implications rather than specific tokens or platforms.

Crypto advocacy groups the Crypto Council for Innovation (CCI) and the Blockchain Association have filed a lawsuit against the state of Illinois over its 0.2% tax on cryptocurrency transactions, arguing the measure violates the U.S. Constitution as well as federal and state laws.

The headline-grabbing reference to threats against the dollar system has drawn the most attention, but the sanctions package goes further. It explicitly names digital assets as a targeted sector, alongside gold, shipping and aviation. Crypto infrastructure is now formally within the scope of Iran-related enforcement.

U.S. Treasury Secretary Scott Bessent warned financial institutions worldwide that any entity enabling money laundering for Iran could be cut off from access to the U.S. dollar system. The Treasury announced new sanctions aimed at five overseas-facing sectors Iran relies on: digital assets, technology, gold, aviation, and shipping. Bessent said the actions widen secondary-sanctions exposure for parties that continue doing business with the Iranian regime.

The U.S. and Canada ended August 21, 2026, as the world's largest bilateral trading partners. By the next morning, the relationship had shifted sharply—at least on paper. Trade negotiations fell apart minutes before a midnight deadline, activating a 50% U.S. tariff on roughly $20 billion in Canadian imports under Section 338 of the Tariff Act of 1930. Canadian Prime Minister Mark Carney responded by pulling Ottawa's negotiating team out of Washington and unveiling a retaliatory tariff package set to take effect September 8. Ottawa's targets include U.S. steel, dairy products, electronics, and appliances, among other items. Washington and Ottawa traded blame for the collapse. U.S. Trade Representative Jamieson Greer said Canada changed its demands late in the process, seeking further concessions after the sides appeared close to a deal. Carney countered that the U.S. position was unreasonable and left Canada little room to negotiate. The breakdown extends a trade fight that has been building since 2025, with tensions spreading across sectors tied to cross-border supply chains. Automotive manufacturing, steel, and agriculture are most exposed because they rely on low-friction movement of goods across the border. A 50% tariff effectively removes that frictionless assumption. The stakes are substantial: annual U.S.-Canada trade exceeds $800 billion. Markets, for now, have taken the news in stride. The S&P/TSX Composite swung in both directions before settling near flat on August 24. The Canadian dollar slipped against the U.S. dollar, but the move was limited, suggesting investors see a serious disruption rather than an immediate crisis. The delay before Canada's retaliation begins means the economic impact may not show up clearly in market and trade data for several weeks. The auto sector warrants close attention. North American vehicle production is highly integrated, with components often crossing the border multiple times before final assembly. Canadian steel makers are also key suppliers to U.S. manufacturers, and a 50% duty would price them out of large parts of the market. The next key date is September 8. Without an agreement, both governments will begin collecting additional tariff revenue while exporters in both countries absorb the costs. For investors with Canadian equity exposure, near-term tariff risk is concentrated in auto-related names, steel producers, and agricultural exporters. Energy remains a factor as well. Canadian oil exports to the U.S. make up a meaningful share of the more than $800 billion in annual trade and could face shifting tariff dynamics under the dispute. A weaker Canadian dollar could cushion some of the blow for Canadian exporters by lowering U.S.-dollar prices, partially offsetting the tariff hit. The trade-off is higher domestic import costs and a more complicated inflation outlook for the Bank of Canada.

Taiwan prosecutors have indicted a senior distribution manager at Nvidia's Taiwan office, accusing him of running a scheme that allegedly moved more than 100 advanced AI servers into China by using third-country routing and forged paperwork to evade U.S. export controls. The Keelung District Prosecutors' Office said it brought charges against nine people on August 24, including allegations of document forgery and breach of trust. The Nvidia manager, identified by the surname Chang, was detained in July as the probe intensified. Prosecutors allege the group shipped high-performance Nvidia GPU-based servers, including B300 and Blackwell models, through transit points such as Japan and Indonesia before they reached China. Authorities said falsified documents were used to make the exports appear compliant. The U.S. first imposed broad restrictions on advanced AI chips headed to China in 2022 and has tightened the rules several times since, turning top-tier Nvidia GPUs into sought-after restricted items for Chinese buyers. Prosecutors are seeking prison terms of up to six years. Seven of the nine suspects had already been detained before the indictment. The case comes as enforcement efforts expand. In March 2026, U.S. authorities charged three individuals tied to Supermicro in a related alleged scheme valued at more than $2.5 billion, describing a network that relied on third-party intermediaries to channel controlled technology into China. Taiwan's case stands out because of Chang's senior role inside Nvidia's Taiwan operations, with access to supply-chain and inventory systems, rather than acting as an external reseller. Nvidia had not publicly commented on the charges as of the indictment. For Taiwan, the prosecution underscores a tougher stance in policing the U.S.-led effort to restrict advanced technology flows to China. Taiwan is home to TSMC, which manufactures Nvidia's most advanced chips, and bringing criminal charges involving an employee of a major customer signals heightened enforcement attention in Taipei.

U.S. Treasury Secretary Bentsen said on Aug. 25 (UTC+8) that the department has not yet carried out any bond repurchases under its buyback program, adding that the next operation is scheduled for Sept. 9. The Treasury previously said that, starting Sept. 9, it will raise the maximum size of its long-term liquidity support buyback operations from $2 billion per operation to at least $4 billion. Market sources also said the Treasury could draw roughly $1 trillion from its Treasury General Account to support the newly announced expansion of the program. (Source: BlockBeats)

NEW: Sen. Cynthia Lummis said the CLARITY Act "has had a lot of landmines placed in its way during the course of the year." She said banks are seeking revisions to the Genius Act—the stablecoin bill that cleared Congress last summer—and want those changes incorporated into the CLARITY Act.
