Oil prices fell in early Asian trading on Tuesday, cutting into gains made in the previous session, as concerns about an oversupply outweighed optimism over a possible resolution to the US government shutdown.

Brent crude futures fell by 13 cents, or 0.2%, to $63.93 per barrel, while US West Texas Intermediate (WTI) crude was down 13 cents, or 0.2%, at $60 per barrel.

Both benchmarks rose by around 40 cents in the previous session.
