Experts Warn Higher Bond Yields Could Pressure Equity Markets
Experts are watching the interest rate paid on US government bonds.
The US 10-year yield is currently 4.8%, close to levels that could worry stock investors.
Some experts say a rise to 5% could cause a quick reaction in stock markets.
Alain Bokobza believes 5.5% could put stronger pressure on stocks because borrowing would become more expensive.
Higher borrowing costs can make company profits and stock prices look less attractive.
Grace Peters still sees possible gains for US and European stocks.
She says a 5% to 8% decline could happen and would be a normal pullback rather than a major collapse.
Experts say earlier earnings upgrades linked to artificial intelligence have helped stocks withstand rising yields so far.
Societe Generale’s Alain Bokobza says a 5.5% US 10-year yield could overwhelm earnings growth and pressure equity valuations.
JPMorgan’s Grace Peters warns that a 5% yield could trigger a psychological shock and knee-jerk equity-market reaction.
Peters still expects potential upside for US and European equities, while describing a 5% to 8% correction as possible.
Barclays’ Emmanual Cau calls bond markets the “elephant in the room” and says investors may become more nervous at 5%.
The US 10-year yield is at 4.8%, while yields across several G7 countries are at multi-year highs.
