(Bloomberg) -- Bitcoin extended a rally amid a brighter mood in global markets and as traders await US inflation data and monitor a seminal upgrade of the Ethereum blockchain.

The largest token rose as much as 3.3% on Monday and was trading a little above $22,000 as of 9:55 a.m. in London. Smaller coins like Solana also pushed higher but Ether lagged behind.

Bitcoin jumped about 10% on Sept. 9, part of a broader embrace of beaten-down assets encouraged by a weaker dollar that hinted at a little less investor fear in a tough year. The greenback continued to slide at the start of the week.

A blackout period for comments from Federal Reserve officials before the US interest-rate decision this month may be one of the factors helping Bitcoin, according to Tony Sycamore, senior market analyst for City Index in Sydney.

“The market knows that it’s got a break from this unrelenting hawkish Fedspeak for a couple of weeks and that the pace of central bank rate hikes is likely to slow,” he said.

The US inflation report due Tuesday is expected to show cooling headline price pressures. But a higher-than-anticipated print could harden expectations for restrictive monetary settings that are anathema for crypto prices.

Any bumps in the upgrade later this week of Ethereum -- the most important crypto network commercially -- could also sow disquiet.

Rising borrowing costs alongside blowups at crypto lenders and hedge funds have saddled Bitcoin, Ether and the wider MVIS CryptoCompare Digital Assets 100 Index with losses of more than 50% in 2022.

Ether, the native token for the Ethereum network, is particularly in focus ahead of the latter’s transition to a more energy-efficient blockchain, a process known as the Merge. The crypto community is on alert for any snafus that buffet the many financial applications that rely on the network.
