Credit spreads are one of the most useful market indicators for assessing financial conditions, risk appetite and the health of the corporate sector. They measure the additional yield investors demand to hold corporate bonds instead of the risk-free US Treasury bonds.<\/p>\n

For example, if a five-year US Treasury yields 4.0% and a five-year corporate bond with a similar maturity yields 5.5%, the credit spread is 1.5 percentage points, or 150 basis points. The additional yield compensates investors for taking on the risks associated with lending to a company, including the possibility of default, deterioration in its financial condition and lower liquidity.<\/p>\n

There are two broad credit markets that investors monitor particularly closely: investment-grade (IG) and high-yield (HY) corporate bonds. Investment-grade companies have stronger credit profiles, while high-yield companies generally have weaker balance sheets and higher levels of leverage. As a result, high-yield spreads tend to be particularly sensitive to changes in economic expectations and risk appetite.<\/p>\n

Why credit spreads are important?<\/p>\n

Credit spreads are important because they provide a real-time market assessment of corporate risk. When investors become more concerned about the economy, they generally demand greater compensation for holding corporate debt. They sell corporate bonds, pushing their prices lower and their yields higher relative to Treasuries. Credit spreads therefore widen.<\/p>\n

The opposite happens when investors become more confident about the economic outlook. Demand for corporate bonds increases, their yields fall relative to Treasury yields and credit spreads tighten.<\/p>\n

Put simply, tighter credit spreads generally indicate improving risk appetite and easier financial conditions, while wider spreads indicate increasing risk aversion and tighter financial conditions.<\/p>\n

What is the relationship with the stock market?<\/p>\n

The relationship becomes important when looking at the stock market. Stocks represent claims on future corporate earnings, while corporate bonds are claims on future corporate cash flows. Credit investors are often more focused on downside risks because they are concerned about whether companies will be able to service their debt. Equity investors, meanwhile, may continue focusing on earnings growth and valuations even when risks are beginning to build in the corporate sector.<\/p>\n

This means credit markets often respond to economic deterioration before it becomes obvious in the equity market.\u00a0Imagine that economic conditions are beginning to weaken. Companies may still be reporting relatively strong earnings because financial statements tend to reflect what has already happened. The S&P 500 may therefore continue rising as investors focus on current earnings and expectations for the future.<\/p>\n

At the same time, however, credit investors may become increasingly concerned about corporate cash flows, refinancing costs and default risks due to changes in the macro or geopolitical conditions. They begin demanding higher yields to hold corporate bonds, causing credit spreads to widen.\u00a0This is one reason credit spreads can lead the stock market.<\/p>\n

There is also an important feedback mechanism. When corporate borrowing costs rise significantly, companies may face higher interest expenses and more difficult refinancing conditions. Highly leveraged companies may reduce investment, hiring or share buybacks. Banks can also become more cautious about lending. The result is a tightening in financial conditions that can further weaken economic activity.\u00a0This makes credit spreads both a signal and a transmission mechanism for changes in financial conditions.<\/p>\n

High-yield spreads are particularly useful in this context because high-yield companies are generally more sensitive to the economic cycle. Their ability to service debt depends heavily on corporate cash flows and economic growth. A significant widening in high-yield spreads can therefore indicate that investors are becoming more concerned about growth, corporate profitability or default risk.<\/p>\n

Why a rise in Treasury yields isn’t always a bad news?<\/p>\n

Credit spreads also help investors interpret movements in Treasury yields. A rise in Treasury yields does not necessarily mean the same thing every time. For example, Treasury yields can rise because investors expect stronger economic growth. If credit spreads are tightening at the same time, the combination can be consistent with improving growth expectations and stronger risk appetite.<\/p>\n

But if Treasury yields are rising while credit spreads are widening, the message is different. It could indicate that investors are facing higher borrowing costs at the same time as concerns about corporate risk are increasing. The implications for equities can therefore be much more negative.<\/p>\n

Traders should be very cautious when the stock market and credit markets begin moving in opposite directions. For example, if the S&P 500 reaches new highs while credit spreads are steadily widening, the divergence can warn of a potential selloff to come. This is what happened before the dot-com bubble burst. Credit spreads were widening, while the stock market continued to rally. Eventually, the stock market crashed.\u00a0<\/p>\n

Keep in mind, that credit spreads can widen temporarily for technical reasons, and not every increase in spreads signals an equity selloff. The signal becomes much more meaningful when the widening is broad, persistent and accompanied by other signs of deteriorating financial conditions.<\/p>\n

Treasury yields, credit spreads and equities are different pieces of the same financial system, and they can provide different information about the economic outlook.\u00a0Because credit markets are highly sensitive to corporate financing conditions and downside risks, they can sometimes turn before the equity market does. This is why investors often monitor credit spreads as an early warning indicator.<\/p>\n
