Crypto news we’re watching

Westpac and Commonwealth Bank involved in world first

In a world-first between mainstream regulated banks, Westpac and Commonwealth Bank used a CBDC (central bank digital currency), being a digital version of the Australian dollar backed by the RBA, to trade and pay for market securities. Imperium Markets hosted the trade last Thursday.

The benefits of running on decentralised ledgers are improved liquidity and  efficiencies in payments, reconciliation and clearing. A lot of the debt markets processes are still manual, operating via phone calls, emails and spreadsheets, creating operational risks. Given new technological risks and need for regulations, banks will proceed with caution.

David Walker, Westpac Chief Technology Officer, said: “A major advantage is the ability to instantly access cash for wholesale investors which they can’t today as it currently takes hours to days. This will allow them to better manage intraday liquidity, creating greater operational efficiency, while also providing transparency for regulators1.”

Bank of Italy partners with Polygon and Fireblocks

Italy’s Central Bank, looking to explore tokenisation of real-world assets, has partnered with Polygon, the Ethereum scaling solution, and crypto custodian  Fireblocks, to develop a DeFi ecosystem for traditional finance.

Over the next six months, Milano Hub, the innovation centre of Italy’s central bank, will look to develop an “Institutional DeFi for Security ecosystem.” The goal is to help traditional finance firms experiment with security tokens and transact using DeFi in a safe and regulated manner.

Milano Hub said, “DeFi is an innovative financial technology based on decentralised protocols that aims to replicate existing financial services in an inclusive transparent manner2.”

CRYP company spotlight

Applied Digital Shares hit ATH (Nasdaq: APLD)

Top 10 holding in the Betashares Crypto Innovators ETF (CRYP) (as at 31 July), Applied Digital, ‘designs, develops, and operates next-generation datacentres across North America to provide digital infrastructure solutions to the rapidly growing high performance computing HPC industry’, according to its website. Currently, 100% of its revenues still come from hosting crypto mining activities, but it has plans to diversify away from crypto mining industry into artificial intelligence (AI).

Last Tuesday, the company announced fiscal Q4 sales had almost tripled and signed its first AI client, which sent shares 17% higher. Revenue went from US$7.5m in the quarter ending May a year ago to US$22m this year. Losses also widened from US$2.3m the previous year to US$6.5m, but the market seems to be hopeful that the signing of two new contracts with AI customers, totalling up to US$640m over 36 months, may prove they have a real AI pipeline3.

Altcoin news

Over the week to 30 July, the largest mover within the Top 20 was Dogecoin (DOGE), with a 11.31% gain. Dogecoin moved to a two-month high on speculation that it could become a payment option on the Twitter platform that has rebranded to X. Twitter owner, Elon Musk, also added the DOGE symbol to his bio.

Musk’s vision for X is that it becomes an “everything” app similar to WeChat in China. Twitter CEO Linda Yaccarino tweeted that: “X is the future state of unlimited interactivity – centred in audio, video, messaging, payments/banking – creating a global marketplace for ideas, goods, services, and opportunities. Powered by AI, X will connect us all in ways we’re just beginning to imagine4.”

Investing in crypto assets or companies servicing crypto-asset markets should be considered very high risk. Exposure to crypto assets involves substantially higher risk when compared to traditional investments due to their speculative nature and the very high volatility of crypto-asset markets.
Investing in crypto assets or crypto-focused companies is not suitable for all investors and should only be considered by investors who (i) fully understand their features and risks or after consulting a professional financial adviser, and (ii) who have a very high tolerance for risk and the capacity to absorb a rapid loss of some or all of their investment. Any investment in crypto assets or crypto- focused companies should only be considered as a very small component of an investor’s overall portfolio
