Brent crude rose 3% to $107 a barrel and WTI to $95, raising pressure.
Analysts linked the yield jump to U.S. growth and a fast-pace PMI, not weakness.
Mohamed El-Erian warned a supply-demand imbalance will keep yields high despite lower oil prices.

History

Historical Context

The 1973 Arab oil embargo, triggered when OPEC nations halted shipments to the United States, caused oil prices to quadruple by October 1973. During the embargo, Brent crude surged to $3 per barrel, a 300% increase, while the 10-year Treasury yield spiked to 10.1%. Today, President Donald Trump’s rejection of Iran’s cease-fire and calls to reopen the Strait of Hormuz echo 1973’s supply shock, pushing Brent to $107 and 10-year yields to 5.26%. The parallel suggests that renewed Middle-East tensions can again force investors into safe-haven bonds, sustaining higher yields and volatile oil markets.
