US Secretary of State Rubio says if Russian President Putin attends the G20, it could be an opportunity to speak with US President Trump

The pattern in episodes where US-Russia engagement has been telegraphed through multilateral summit sidelines is a sequence of trial balloons, then staff-level groundwork, then either a confirmed bilateral or a quiet walk-back, with sanctions, energy flows and any ceasefire track the substantive variables rather than the optics of the meeting itself. The Secretary of State's phrasing, built on a conditional attendance that is itself uncertain, leaves the remark several steps removed from anything tradeable. Where such headlines have moved markets in the past, the transmission has run through crude and European gas on sanctions-easing speculation, and through gold and the franc and yen on the risk sentiment side, but those moves have historically faded absent confirmation of an actual agenda. The tells worth watching are whether the Kremlin confirms attendance, whether a formal bilateral is scheduled rather than a pull-aside, and whether officials on either side attach specific subjects such as Ukraine or sanctions to the encounter. As it stands this is atmospherics.
