According to Jin10, the New Zealand dollar gave back earlier gains in early European trading on Thursday and turned lower against the U.S. dollar as market sentiment weakened. Escalating tensions in the Middle East pushed oil prices higher and lifted U.S. Treasury yields, limiting further dollar losses after its Asian-session decline. Yemen's Houthi movement attacked a Saudi airport again, driving oil prices higher. Brent crude rose to around $102 a barrel as concerns grew that Saudi oil facilities could face further attacks and supply constraints. Higher crude prices also pushed U.S. Treasury yields higher, as markets believe elevated energy prices will force central banks to tighten monetary policy. That offset the dollar's slight weakness after the Federal Reserve's September meeting minutes showed the Fed still worried about inflation but did not change market expectations for unchanged rates in October.
