Fluctuations in credit spreads serve as an indicator of investor sentiment and capital flows in the corporate bond market. “Credit Signal” intuitively analyzes the overall market trends and context by focusing on weekly changes in credit spreads. <Editor’s Note>

[E-Daily Marketin Reporter LEE GEON-EOM ] Although corporate bond spreads remain stable, interest rates are skyrocketing, pushing companies’ financing burdens to their limit. While there are no signs of a severe liquidity crunch in the market—thanks to higher-than-expected economic growth and the inflow of “semiconductor money”—rising interest rates are directly translating into higher interest expenses for companies, suggesting that potential risks are mounting.

According to the Bond Information Center of the Korea Financial Investment Association on the 18th, the yield on 3-year unsecured corporate bonds (rated ‘AA-’) stood at 4.726% as of the previous day, the 17th. On the 15th, the rate soared to 4.750%, setting a new high for the year. This represents a sharp increase of more than 130 basis points (1 bp = 0.01 percentage point) from the 3.4% level seen in early January.

It is noteworthy that, even amid this sharp rise in yields, credit spreads have actually narrowed or remained stable. Credit spreads refer to the difference between the yield on government bonds—which are considered safe assets—and the yield on corporate bonds issued by individual companies.

As of yesterday, the spread between 3-year government bonds (4.063%) and “AA-” rated corporate bonds stood at 66.3 basis points. This is a significant narrowing compared to 72.3 basis points on August 5, early last month. The market interprets this as a result of institutional investors’ robust pent-up demand for high-quality bonds, which is strongly supporting the spread.

The problem is that, regardless of the spread, the cost of issuing long-term debt—which has reached the 4.7% range—is itself placing enormous pressure on companies. As expectations for an interest rate cut cycle fade and concerns about prolonged high interest rates grow, the interest burden on companies that engaged in preemptive fundraising is snowballing.

Particular concern stems from the fact that conditions in the short-term funding market are following a similar trend to those in the long-term market. In fact, the yield on 91-day corporate commercial paper (CP)—which had remained stable around the 3.15% mark until mid-August—has been on a steady upward trajectory, reaching 3.26% as of the 17th. In addition to the interest rate burden in the long-term corporate bond market, the short-term funding market also appears to be gradually reflecting concerns over tightening liquidity in its pricing.

The market views the current stability in spreads as largely attributable to supply and demand rather than an improvement in corporate fundamentals. This is why warnings are emerging that, as the fourth-quarter book-closing season for institutions approaches, the funding environment could become even more strained—in addition to the interest rate burden—if even the latent buying demand that has been holding onto high-quality bonds begins to subside.

A bond market official expressed concern, stating, “Although credit spreads are remaining tight, the funding conditions companies actually experience remain fragile because Treasury yields have risen so sharply.” He added, “With expectations for interest rate cuts fading and uncertainty mounting, there is growing concern about the shock the market would face if spreads were to waver due to a liquidity shortage.”
