Iran has once again threatened to block the Strait of Bab al-Mandab, a strategic chokepoint for maritime oil transport. According to FX Street, this waterway has become critical for Saudi exports that have been rerouted away from the Strait of Hormuz due to ongoing regional tensions.

Commerzbank has highlighted that this renewed threat significantly heightens geopolitical risks surrounding global oil supplies. The potential disruption at Bab al-Mandab could ripple through international markets, further complicating an already fragile energy landscape.

For Japanese investors and traders, this development underscores the increased volatility risk in energy markets, particularly in FX and equities linked to oil prices, given Japan's reliance on stable oil imports for its economy.
