Saudi army conducted missile attack on areas of Amran and Saada provinces in northern Yemen, according to IRNA

Saudi strikes on Amran and Saada, the Houthi heartlands along the northern border, are a recurring feature of this conflict and in past cycles have tended to signal an escalation or breakdown of ceasefire arrangements rather than a new phase on their own. The sourcing matters here: IRNA is an Iranian state outlet, and reports of Saudi operations carried first through Iranian media have historically been contested or timed for narrative effect, so confirmation from Saudi or independent channels is the immediate tell. The transmission channel on genuine escalations of this kind has run through crude via the risk premium on Gulf supply and through freight and insurance costs on Red Sea and Bab el-Mandeb shipping lanes, rather than through any direct output loss, since these provinces are not producing or transit infrastructure. The distinction worth drawing is between a routine border strike, which past episodes suggest fades quickly, and one that accompanies a collapse of back-channel talks or renewed attacks on Saudi energy facilities or shipping, which is when the crude premium has tended to build. Worth watching is Houthi retaliation rhetoric, any threat to tanker traffic, and whether Riyadh confirms or stays silent.
