What happened
Brent crude futures fell below the $100-per-barrel mark, according to a report from Hafu Express carried by East Money.
The move marks the first time the benchmark has traded under that level since September 9.
Why it matters
The $100 level is a widely watched psychological threshold for oil markets, so a break below it can shift sentiment among traders and feed into expectations for fuel and energy costs.
Because the source gives no reason for the decline, the driver remains unclear from the available information.
