Bond Selloff Upends Markets as Long-Term Borrowing Costs Surge

A selloff in global bond markets gathered pace, driving long-term borrowing costs in the US and Europe to the highest level in more than a decade, quashing appetite for riskier assets and dimming the outlook for growth.

(Bloomberg) — A selloff in global bond markets gathered pace, driving long-term borrowing costs in the US and Europe to the highest level in more than a decade, quashing appetite for riskier assets and dimming the outlook for growth.

Traders are bracing for an extended period of tight monetary policy, and demanding ever higher compensation to hold long-dated government debt. The repricing — which sent the yield on 30-year US Treasuries past 5% for the first time since 2007 — is spilling over into equity and corporate bond markets. 

“US yields at highs for the year are starting to look disruptive for other regions and sectors,” Steven Major, global head of fixed-income research at HSBC Holdings Plc., wrote in a note to clients.

The moves come as European Central Bank and Federal Reserve officials make it increasingly clear they are unlikely to ease policy any time soon, and are being compounded by concern over swelling government deficits and increased bond supply.

The 30-year US Treasury yield extended its largest quarterly jump in more than a decade. The German 10-year rate climbed to 3% — a level unseen since 2011. In Japan, swaps used to bet on 10-year bond yield shifts touched 1% for the first time since January.

“One thing that makes me nervous is the speed of the selloff which could weigh on market sentiment,” said Alexandra Ivanova, a fund manager at Invesco.

The jump in US yields, which now tower over peers, has powered a rally in the dollar over recent days, sending the euro to the weakest level in almost a year and driving the yen to 150 per dollar on Tuesday. 

The volatility has also spilled over to stocks and corporate notes. The S&P 500 index dropped to a four-month low on Tuesday while a key gauge of credit risk for Europe’s sub-investment grade companies surged to the highest since May.

“These moves are starting to cause worries across all asset classes,” said James Wilson, a money manager at Jamieson Coote Bonds Pty in Melbourne. “There’s a buyer’s strike at the moment and no one wants to step in front of rising yields, despite getting to quite oversold levels.”

Global bonds are down 3.5% in 2023 and yields worldwide are now at levels almost unthinkable at the start of 2023. The selloff has been so extreme it’s forced bullish investors to capitulate and Wall Street banks to tear up their forecasts.

The sharp moves have driven a measure of Treasuries volatility to the highest since May on Tuesday, while the correlation between Bloomberg’s gauge of global securities and an index of US government bonds soared to the most elevated since March 2020.

Emerging markets are also feeling the pain. The additional yield investors demand to own developing-nation sovereign dollar bonds rather than Treasuries jumped to a three-month high Tuesday, sending average borrowing costs to almost 9%. 

“Long EM duration is a pain trade for most real money investors,” Morgan Stanley analysts including Min Dai wrote in a note. Such positioning “increases the vulnerability of the market, especially if US Treasury rates continue to march higher.”

But the very short end of the Treasury market still looks attractive to some. An enlarged 52-week bill sale on Tuesday attracted record demand from non-dealers, as investors locked in a yield above 5% for the next year.

Current yield levels will “suck capital away from the more risky asset classes,” said Wilson from Jamieson Coote. “Investors do not need to move along the risk spectrum to generate attractive returns.”

The rout has also sent so-called real yields to multi-year highs, with the 10-year US inflation-adjusted rate climbing above 2.4% to the sort of levels reached in 2007.

“What’s the price for US 10-year yields if the US economy illustrates normal growth? It’s well in excess of 5% and that’s where we are going,” said Peter Kinsella, global head of FX strategy at Union Bancaire Privee Ubp SA.
