Bumpy road: Market shock to diplomatic uncertainty

26 June 2026
Brent crude surged from around $70 per barrel (bbl) in mid-February to almost $120 bbl in late March before retreating to around $80 bbl following the ceasefire and signing of a memorandum of understanding (MoU) between the US and Iran.

The Russia-Ukraine war, now in its fifth year, continues to weigh on oil and gas markets through intensifying conflict and infrastructure attacks, with no credible diplomatic off-ramp visible in the near term. The overall risk landscape has become more concentrated around a smaller number of high-impact, high-likelihood flashpoints.
