Oil prices have firmed amid fading optimism over a potential deal between the US and Iran, which has heightened concerns about supply risks. According to FX Street, ING analysts Warren Patterson and Ewa Manthey highlight that the diminished prospects for an agreement are keeping the market cautious.

The uncertainty surrounding US-Iran negotiations contributes to an environment where supply disruptions remain a key risk factor for oil markets. This dynamic has supported prices despite broader market pressures.

For Japanese investors, ongoing supply uncertainties in global oil markets could influence energy costs and impact related sectors, underscoring the importance of closely monitoring geopolitical developments.
