World shares hit a three-week high on Wednesday and US index futures were indicating a steady open on Wall Street as strong US corporate earnings and the expected resumption of Russian gas supply to Europe tempered recession fears.
The dollar was trading near two-week lows on lower US rate hike expectations.
Russian gas flows via the Nord Stream 1 pipeline are seen restarting on time on Thursday after the completion of scheduled maintenance but at lower than its full capacity, two sources told Reuters, reducing investors' concerns about gas supply to Europe in tat-for-tat measures in response to the Ukraine conflict.
Markets still expect a large 75-basis-point interest rate rise from the US Federal Reserve next week to rein in white-hot inflation. But this represents a rowback from previous expectations of 100 bps.
In contrast, Reuters reported European Central Bank policymakers are mulling raising rates by a bigger-than-expected 50 basis points on Thursday.
"At the margins there is some good news like Nord Stream," said Luca Paolini, chief strategist at Pictet Asset Management.
"Overall, there is no reason why the market should rally that much, but it springs from inflation expectations."
S&P 500 futures and Nasdaq futures were flat, after a strong showing overnight on better-than-expected results from US companies including Netflix Inc.

The dollar gained 0.3 per cent to 107 against an index of currencies, but remained close to two-week lows hit in the previous session.
"The FX market has an even shorter-term focus than usual," said Societe Generale strategist Kit Juckes.
"The Nordstream 1 pipeline reopening, Italian political stability and whether the ECB hikes by 25 bps or 50 bps tomorrow matter more than what might happen in 2023. With such a short-term focus, of course volatility stays high."
