Crypto News Round-Up — September 2025

September’s crypto markets have seen a flurry of regulatory and market developments. Key stories from the past day include the UK’s wavering stance on stablecoin regulation, a major capital raise for a leading stablecoin issuer, changes in U.S. ETF rules, and signals of large stablecoin growth – all amid an ongoing focus on crypto security. We review the highlights and their implications below.

• UK Stablecoin Regulation Limbo
• Tether Eyes $500B Valuation
• SEC Eases Spot ETF Rules
• Stablecoin Supply Boom
• Crypto Security & Hacks

UK Stablecoin Regulation Limbo

A recent Reuters report (Sept 23) warns that the UK’s indecision on stablecoin regulation could leave it trailing other markets. With global stablecoins pegged to dollar, euro, yen and more now a $280+ billion market, the US, EU and Japan have largely defined rules. In contrast, the UK “remains in limbo” on how to oversee these assets, potentially depriving British businesses and consumers of protections and opportunities (Reuters).

• Without clear laws, UK firms may fall behind as global stablecoin standards evolve.
• Consumers in the UK could face higher risks if current unregulated stablecoins are used without safeguards.
• Establishing a framework soon could help the UK tap into the booming stablecoin market.

Tether Eyes $500B Valuation

Reuters reports that Tether, the company behind the USDT stablecoin, is exploring a $15–20 billion private funding round that would imply a valuation around $500 billion. This early-stage raise, reported via Bloomberg News, reflects the massive scale of stablecoin issuance today. USDT is by far the largest stablecoin by supply, and a fresh capital infusion would be one of the largest fundraising rounds in crypto (Reuters).

• A successful raise could strengthen Tether’s market position and support further stablecoin growth.
• The implied $500B valuation highlights how high demand has become for dollar-backed crypto tokens.
• Investors’ interest in Tether suggests confidence in stablecoins as core infrastructure for crypto finance.

SEC Eases Rules for Spot Crypto ETFs

Late last week the U.S. Securities and Exchange Commission approved rule changes to simplify the listing process for spot cryptocurrency ETFs on major exchanges. Under the new rules, venues like NYSE, Nasdaq and Cboe will no longer need separate SEC permission for each new Bitcoin or Ether ETF listing. The change – reported by Reuters on Sept 18 – clears a major hurdle for crypto fund issuers and is expected to speed up approvals of new spot BTC/ETH ETFs (Reuters).

• Easier listings could lead to more Bitcoin and Ethereum ETFs hitting the market in the coming months.
• Streamlined approval gives institutional investors faster access to diversified crypto products.
• The move signals regulatory acceptance and may boost market confidence in mainstream crypto adoption.

Stablecoin Supply Booms, Deals Grow

Crypto analysts note that stablecoins continue to expand rapidly. An Axios crypto newsletter (Sept 23) highlights that total stablecoin supply is nearing $300 billion as more issuers enter the market. Even as token prices have been stagnant, stablecoins are being issued aggressively to facilitate trading and DeFi activity. The newsletter also reports a wave of mergers and acquisitions, suggesting industry consolidation is underway amid these liquidity changes (Axios).

• A surge in stablecoins reflects growing demand for dollar-backed crypto in trading, lending and payments.
• Rising stablecoin issuance has enabled more dealmaking and consolidation in the crypto industry.
• Monitoring this supply growth is key, as it impacts liquidity for Bitcoin, Ethereum and other tokens.

Crypto Security & Hacks

Security remains a top concern: Reuters notes that crypto thefts reached $2.2 billion in 2024, a record high for the industry. Major hacks like the $1.5 billion Ethereum theft in early 2025 underscore this trend (Reuters). While no new exploit has dominated the headlines in the past day, analysts warn that vulnerabilities persist in both cryptocurrency exchanges and DeFi platforms.

• Last year’s $2.2B in hack losses shows that cryptocurrency remains a target for cybercrime.
• Investors should remain cautious, as even large exchanges or projects can face breaches.
• Regulators and firms are likely to continue strengthening security standards in response.

Bottom Line

This week’s news highlights both the momentum and the challenges in crypto. Regulators in the U.S. are facilitating new investment vehicles, while the U.K. risks falling behind without clear policies. Stablecoin markets and fundraising are booming, reflecting strong investor interest and liquidity. At the same time, high-profile funding ambitions and rapid token issuance underscore the importance of security and oversight. As always, market participants should stay informed and cautious amid this evolving landscape.
