Oil market volatility amid the conflict in the Middle East has started to ring alarm bells for Asian refiners. Hamas' surprise attack on Israel has fanned worries of a long-drawn period of geopolitical turbulence at a time when global oil markets are already been facing a squeeze in supplies, while demand continues to grow. This has rekindled the debate on oil crossing the $100/b threshold again.  S&P Global Commodity Insights' Asia energy editor Sambit Mohanty speaks with Kang Wu, head of global demand and Asia analytics, and Daniel Colover, head of market engagement for the Middle East, on how some of the recent geopolitical developments, including the removal of sanctions on Venezuela, could potentially affect Asian oil markets.
