FXStreet (Mumbai) - Oil prices are down once again as the concerns of excess supply persists, dragging the treasury yields lower as well. At the time of writing, the WTI futures were down 0.43% or 16 cents at USD 36.16/barrel. Brent futures were down 18 cents at USD 37.74/barrel. Meanwhile, the benchmark 10-yr yield was down almost 2bps at 2.209%. The 2-yr yield, which mimics rate hike expectations, fell 1.2bps to 0.944%.
