Cryptocurrencies extended their weekend slide on Monday, hampered by a further drop in the <a href="https://www.thenationalnews.com/business/cryptocurrencies/2022/09/17/ether-drops-to-lowest-in-seven-weeks-as-traders-divert-attention-from-the-merge/" target="_blank">second-largest token, Ether</a>, as well as the prospect of a <a href="https://www.thenationalnews.com/business/economy/2022/09/17/goldman-cuts-us-growth-forecast-for-2023-after-change-in-fed-rate-hike-path/" target="_blank">global wave of monetary tightening</a>. Ether fell as much as 10.04 per cent to a two-month low and was trading at $1,308.36 at 9.20am UAE time on Monday, while <a href="https://www.thenationalnews.com/business/cryptocurrencies/2022/09/07/bitcoin-slumps-as-crypto-market-capitalisation-dips-below-1tn/" target="_blank">Bitcoin receded</a> 6.06 per cent to $18,822.29. Tokens such as XRP, Avalanche and Polkadot posted heavier losses. An Ether jump since mid-June that was spurred by hype around an <a href="https://www.thenationalnews.com/business/cryptocurrencies/2022/09/13/ethereum-merge-blockchain-upgrade-set-to-cut-energy-use-by-995/" target="_blank">upgrade of the Ethereum blockchain </a>is rapidly unwinding now that the revamp is done. Meanwhile, investors are bracing for volatility from the jumbo interest-rate hike expected this week from the US Federal Reserve to fight price pressures. The Ethereum update — known as the Merge — to slash energy usage is a “ginormous shift” but “in this inflationary environment macro trumps everything”, Antoni Trenchev, managing partner at cryptocurrency lender Nexo, wrote in a note. That is evident in the pressure on a range of assets: global stocks are closer to wiping out a climb since mid-June that for many was a bear-market rally. US equity futures were in the red on Monday, while a dollar gauge pushed higher. Elsewhere, reports that Ripple Labs and the US Securities and Exchange Commission are seeking an immediate ruling in a court case over Ripple’s affiliated token XRP saw the latter shed as much as 12 per cent. The SEC argues Ripple was “reckless” in its claims that XRP is not a regulated security.
