Global markets opened under pressure on September 15 as surging oil prices and rising government bond yields combined to unsettle investors.
Oil and rates collide
Reuters reported that the MSCI World index fell while European shares declined. At the same time, the U.S. 10-year Treasury yield moved above 5 percent as traders priced a higher probability of additional Federal Reserve tightening.
Why the combination matters
Higher oil prices can feed inflation, while higher bond yields increase the return available from relatively low-risk assets. That can make expensive growth stocks less attractive and raise the cost of borrowing for businesses and households.
What investors will watch next
Markets are likely to focus on whether energy prices stabilize, whether inflation expectations rise further and how central banks respond. Companies with heavy fuel exposure and high financing needs could face the sharpest pressure.
