Credit markets dented as Middle East war adds another worry for investors
Impact of Middle East Conflict on European and U.S. Credit Markets
By Amanda Cooper
LONDON, March 2 (Reuters) - A number of key European credit indicators deteriorated on Monday, with an index of regional junk corporate credit hitting its highest yield since November on investor jitters over conflict in the Middle East and the fragility of the private credit market.
The U.S.-Israeli air war against Iran expanded to Lebanon as Israel responded to strikes by Hezbollah, while Tehran fired missiles and drones at Israel, Gulf states and a British air base in faraway Cyprus.
As sentiment faltered, investors ditched riskier assets such as credit, cryptocurrencies and equities.
Rising Default Insurance Costs and Market Stress
Surge in Cost of Default Insurance
The iTRAXX Europe Crossover index, which captures the cost of insuring against the risk of default on a basket of high-yield corporate debt, rose by nearly 11 basis points to around 270 bps, following the largest one-week rise last week since early October.
A similar measure of investment-grade credit, the iTRAXX Europe Main, rose by 1.5 bps to around 57 bps, the most since mid-October.
Last week's collapse of a niche British mortgage financing company has added to investors' worries over ballooning corporate debt levels related to the artificial intelligence boom, as well as over lending standards.
Much of this borrowing has come via private credit, typically less transparent and liquid than public markets, and more liable to seize up in the event of a shock to the financial system.
Expert Commentary on Credit Risks
"One should not lose sight of everything that is going on in the credit space (where spreads have in some cases been wafer-thin), and a known (difficult to quantify) risk that has in recent weeks been coming more and more to the fore - namely private markets and the exposure of banks through their lending books, to non-bank financial institutions," said Saltmarsh Economics chief economist David Owen.
JPMorgan boss Jamie Dimon said late last year that more "cockroaches" could emerge from pockets of Wall Street's multitrillion-dollar credit machinery.
Market Reactions and Potential for Recovery
A Possible Bounceback?
There were no new deals in the U.S. investment-grade bond market on Monday, according to International Financing Review (IFR) data. This will likely change on Tuesday after investors digest the latest geopolitical developments, according to Hans Mikkelsen, credit strategist at TD Securities.
"Today credit is already back to Friday's levels in many cases after the weakness overnight and in the morning," Mikkelsen said. "I expect the primary market to reopen tomorrow with a full plate."
At Friday's close, the ICE BofA U.S. Corporate Index traded at 118 bps, highest since late November, according to ICE data.
The ICE U.S. High Yield Index closed Friday at 312 bps, also the highest since late November, ICE data showed.
Broader Economic Implications
Short-dated U.S. Treasury yields rose as investors grew concerned about a surge in oil prices and a potential spike in global inflation.
"The regional concentration of global oil and gas supply flowing through the Strait of Hormuz and heightened uncertainties around the nature of the conflict point to elevated tail risks," said Nelson Jantzen, who covers high-yield bonds, leveraged loans and distressed leveraged credit at JPMorgan, in a note.
European shares fell broadly, led by losses in travel and leisure stocks, while bank stocks tumbled. Shares in major lenders such as HSBC, Banco Santander and Deutsche Bank fell 4% to 5%.
