Oil prices soared again on March 3 as the Ukraine war sparked a run on commodities that raised fears of “stagflation” and stocks on Wall Street and in Europe fell as investors hoped central banks will be prudent as they move to tighten monetary policy.

The fresh surge in energy prices heightened worries about the European economic outlook, leading the euro to slide to its lowest level in almost six years against Britain's pound and pinning it near 21-month lows versus the dollar.

Brent crude futures, the international benchmark for oil, climbed to within 16 cents of $120/bbl before paring gains on signs of progress toward removing remaining issues blocking a revival of the 2015 Iran nuclear deal.

The yield on 10-year Treasury notes fell 2.8 basis points to 1.837%.

Germany’s 10-year government bond yield, the benchmark of the bloc, rose 0.9 basis point (bps) to 0.019%.
