Credit spreads: Is there something you're not telling me?

10 min read 21 Oct 25

Corporate bond markets are showing signs of complacency, with tight spreads masking deep macroeconomic and geopolitical risks. In a market facing elevated government debt levels, questions around central bank independence, as well as both macro and micro economic risks, Harriet Habergham unpicks how bond investors can navigate this environment. 

Corporate bond markets are playing ostrich. Spreads are tight, valuations stretched and investors are chasing yield with a blissful detachment from risk. Underneath this lies a complex reality.

Credit spreads are at historically tight levels. As at the end of August 2025, the ICE BofA US Corporate Index Option-Adjusted Spread was at 0.78, the lowest since June 1998.  

“Spreads over governments are too thin and that’s even before you consider what is going on in the world – there are a lot of risks around.”

After a decade of ultra-low interest rates and pallid growth, investors were left hungry for yield. In the period following the COVID crisis, which sparked an inflationary uptick and left central banks scrabbling to hike interest rates, investors have piled in, buying up yield. Ben Lord, manager of the M&G Global Corporate Bond Strategy, acknowledges that “all-in yields are attractive”, with investment grade (IG) bonds in the US and UK having yielded somewhere between 5% and 6% for a high-quality company.

However, Lord highlights that around 4% to 5% of this figure is generated by the government bond yield, meaning only circa 100 bps is generated by the credit spread (the difference between the corporate bond yield and the government bond yield).  

“Spreads over governments are too thin and that’s even before you consider what is going on in the world – there are a lot of risks around,” he says. 

At current levels, spreads paint a picture of strong company fundamentals, a positive macroeconomic backdrop and a sunny horizon.

However, underneath the surface are a myriad of risks, with the largest risks most likely to be those we cannot know yet. In the words of Richard Ryan, co-head of Fundamental Fixed Income, “we are always operating in the grey.” He adds: “We can’t always know where we’re going but we need to know where we are now.”

He highlights that over the last two decades, we have experienced six significant credit market sell-offs, of which only one of those, the global financial crisis (GFC), came from a corporate credit consumer leverage problem. The remaining five were sparked by external factors ranging from a global growth scare to a pandemic. Strong fundamentals aren’t necessarily a guarantee that a company won’t be susceptible to market shocks. Furthermore, with valuations where they are, there is no margin for error in the event of such an external shock.

As Nick Smallwood, manager of the Emerging Market Bond Strategy, outlines: “The markets are brushing these risks off,” but he warns that if we experience an event which causes the market to fall out of bed, “it could fall out of bed quite hard.”

The risk-free rate

The corporate bond yield is made up of two components: the relevant underlying government bond yield (also known as the risk-free rate) and the credit spread (or risk premium) for lending to a company.

A question weighing on investors’ minds is how risk-free is the risk-free rate? In a world where government bond yields have surged as many governments amass more and more debt without a sustainable solution, is there a point where spreads over government bonds could turn negative?

“The fiscal reality of the world that we live in today means that risk free rates aren’t the same as they were and aren’t the same as they should be – that’s just the nature of an overborrowed government,” Lord argues.

“The fiscal reality of the world that we live in today means that risk free rates aren’t the same as they were and aren’t the same as they should be – that’s just the nature of an overborrowed government.”

“I think the risk-free rate is a term that needs to be revisited, especially given the fiscal situation that we ourselves in large parts of the world [are experiencing], and the huge demographic shift as the ‘baby boomer’ generation retires.”

The debt-to-GDP ratio in OECD countries reached 111.6% in 2022, compared to 51.3% in 20001, showing the inexorable rise in debt levels in developed markets (DM). Not only have debt burdens increased, but debt servicing costs have risen, making up 3.3% of national income in 2024, compared to 2.4% in 2021 for OECD countries.  

Given the comparative health of IG corporate balance sheets, could spreads over government bonds turn negative?

Historically in recessionary periods or times of crisis, the widening of corporate bond spreads is offset by a rally in government bonds, providing an element of protection. However, governments have provided a strong fiscal impulse, taking on substantial levels of debt, when growth is still reasonably healthy. As Lord highlights: “The fact we are worried about fiscal risks when the sun is shining is concerning.” In a recessionary scenario, tax revenues will drop while government expenses rise, meaning governments would need to borrow more to fill that hole. Ryan likens running a government to running a household budget; the recent leap in debt burdens, he says, is akin to having your mortgage rate doubled or tripled in cost, eating up spending power and rather than reining it in and borrowing more and more on the credit card.

If governments continue to take on higher debt loads, it could create a scenario where a risk-off event, such as a recession, could see credit spreads move wider, while government bond yields remain elevated, leaving the developed world in a fiscal crisis. At this point, higher quality names could trade at government bond yields or lower.

“In this scenario, our long-term valuation framework of taking credit risk when we are paid for it would have reached its extreme conclusion,” Lord says.

However, while this scenario could occur, it is unlikely to be long-lasting. Companies operate within a legal framework. If the public sector is struggling for money while the private sector remains relatively strong, governments will turn to both wealth taxes and corporation taxes to take resources.

Furthermore, governments will be able to pull the levers of the printing press and quantitative easing, making a default highly improbable. Instead, the economy would face inflation and the devaluation of currencies, which would present different opportunities and different threats to companies.

Nevertheless, as Lord highlights, it is important to be asking whether government bonds do offer a risk-free rate or whether they will find themselves in the crosshairs of the bond vigilantes in a risk-off event.

A murky macroeconomic picture

With growth and inflation hanging delicately in the balance in many countries, the future path of interest rates in different regions across the globe remains a key risk for bond investors. The trajectory of both growth and inflation will become clearer as the ramifications of tariffs, heightened geopolitical risk and the impacts of a prolonged period of higher interest rates play out. However, the macroeconomic picture remains murky, with significant divergence across regions.

Smallwood highlights that for most of the world, a lot of the risks are “emanating from the US”.

The path of US inflation remains bumpy, coming in at 2.9% in August, higher than the Fed’s target rate, and many believe tariff-induced price increases are still working their way through the market.

Meanwhile, weakening labour market data, alongside potential tariff-related impacts on US economic activity, caused the Fed to resume its interest rate cutting cycle in September, which has been supportive for fixed income. However, with many investors banking on further cuts, Ryan warns that the market’s fixation on easier monetary policy and lower rates could be a risk if these don’t transpire.

“We don’t know what the effects of trade policy are yet because a lot of the data is backward-looking. We can see some trends, where consumers in the US rushed out to buy their cheap goods on Amazon ahead of the tariff policies and now consumer demand is dropping off,” he explains. “So we are in a period of fluctuation, [and] we won’t know what the world looks like for a couple of quarters while everything washes through the system and we get some stability.”

US monetary policy has received a lot of attention, not just from investors but from the president himself. After bringing interest rates down to 4.5% in December 2024, the Fed subsequently held rates steady for five consecutive meetings. During this period, Trump repeatedly exerted pressure on the central bank to lower interest rates, engaging in various tactics from personal attacks against Fed Chair Jerome Powell to seeking to oust members of the Fed’s Board of Governors. 

“Political intervention in the central bank could call into question the credibility of policy in the US, undermining a key stabilising factor in its financial system.”

“If the central bank was to lower rates without having the economic backdrop to warrant it, then you start getting worries around Fed independence and so on, [and] that’s going to cause problems across all markets – not just emerging markets (EM),” Smallwood argues.

Muddying the picture further

Another risk facing corporate bond investors lies in assessing the image of corporate health. There has been an increased prevalence of liability management exercises (LMEs). Default rates are currently elevated but stable. However, this may not be the full picture. LMEs are essentially a debt restructuring technique where a company can alter existing debt, sometimes forcing losses onto creditors. This aggressive company behaviour can distort default numbers. According to Ryan: “If you include LMEs, the default numbers would be elevated and we would see a reaction in spreads, yet they remain low.”

As Ryan points out, prior to the GFC there was a belief that economic cycles were a thing of the past and therefore it was possible to take on more leverage without fear of a recession. However, “that leverage built and built, until it cracked,” he says.

The advent of private credit has also served to obfuscate the picture, providing borrowers with avenues to avoid “default in the traditional sense, and instead default by the back door,” adds Lord.
 

Zooming in

Having considered the risks posed to corporate bonds on a macroeconomic level, it is equally as important to consider the microeconomic shocks. This was demonstrated in early 2025, as China unexpectedly pulled ahead in the AI race. The release of the DeepSeek AI chatbot in January 2025 demonstrated how a single company can have a profound impact on not just a sector, but a whole market.

Ryan highlights household names that have disappeared such as Kodak, Polaroid and Nokia. “Companies can come along and change our marketplace, but there is always another company nipping at your heels and the whole world could change again,” he argues.

“Companies can come along and change our marketplace, but there is always another company nipping at your heels and the whole world could change again.”

“We need to be humble enough to know that we might not see these things coming, but they will have an outsized effect on the marketplace.”

While a single disruptor can pose a risk to a whole market, the remaining companies can still provide opportunities for fixed income investors. Ryan highlights Xerox as a good example; fewer people use its products and there is a visible path of decline. However, if you are being paid a substantial risk premium that takes these factors into account, the firm could still present an attractive possibility. For a bond investor, we believe it is a risk worth taking if you are being paid to do so.
 

The name of the game

Given the complex, volatile landscape, accompanied by generationally tight credit spreads, how does an investor navigate this?

For Lord, if the largest proportion of IG yield is coming from the government bond yield, then it makes sense to reduce credit risk and add risk through a long duration position in government bonds.

“I’ve always done the same thing when spreads get down to these levels: sell risk and wait for a correction. It can take a long time or happen quickly, this time it is taking a long time for risk to correct,” he says.

However, Lord argues that “something always comes along – you never know what it is, you cannot predict what it is, but you can look at valuations; we use spreads in credit risk terms and when they are this tight you sell and you wait.”

Ryan agrees, adding: “There is a huge amount going on in each jurisdiction and I think people are struggling to assess that risk.”

In this scenario, it is important to be nimble and ready to react when valuations reach attractive levels again, because the market tends to sell off suddenly and rapidly.

For example, while certain spreads widened to an extent in the bout of tariff-related volatility in April 2025, markets were quick to retrace and it was a very short window of opportunity. Furthermore, markets didn’t experience a full sell-off, with only certain sectors such as autos, pharmaceuticals and to some extent travel selling off to attractive levels, offering a fleeting chance to go out and buy.

“For us at the moment, it is a question of being confident in the knowledge that even if we don’t know what is going to happen, something will come along and present an opportunity – it always does,” Ryan adds.

The current complacency exhibited by markets, while dangerous, offers active managers a potential to pick up the pieces when something eventually cracks.

“Our goal is to be the last man standing when the market cracks,” Ryan explains. “To be the person picking up the pieces and buying into these assets. The great thing about being able to do that is you don’t need to buy the riskiest assets at that point, [because] good quality assets are really cheap and you can make decent returns.”

In the meantime, Ryan prefers to take advantage of sectoral shifts, “which helps you put runs on the board and keep yourself ticking along, waiting effectively for that opportunity where you can really meaningfully change the risk profile.” Discipline and agility is the name of the game.
 

An emerging opportunity

Similarly to DMs, corporate credit spreads in EMs are also tight. However, in EMs, this is reflective of strong fundamentals: most corporates are not too indebted, balance sheets are strong and local rates are coming down.

However, as Smallwood points out, despite this strength, “you do still get paid more to be in EMs, even in IG.” He highlights that this has been reflected in flows as DMs investors have been “looking to get a bit more bang for their buck out of EMs, particularly in IG.”  

EM corporate bonds offer investors an opportunity to pick up extra yield without forgoing credit quality. 

“EM corporate bonds offer investors an opportunity to pick up extra yield without forgoing credit quality.”

Smallwood highlights strong names, such as Singaporean banks or the Qatar National Bank, which while not necessarily as large as US counterparts, are “rock solid” credits, that have been supported by liquidity and a strong macroeconomic backdrop while providing high yields. The risk/reward profile of EM credits looks stronger than that in DM. For example, if you take Banco do Brasil – a majority state-owned bank diversified across a G20 economy – versus a US monoline oil company, Banco do Brasil likely pays more than the US oil company, despite both being BB rated.

We are seeing this in high yield (HY) markets too, with EM HY corporates giving a spread of circa 440 bps, while US HY has a spread of just under 280/290 bps. This is despite an arguably weaker fundamental outlook for US HY, an asset class more afflicted by tariff uncertainty, which could affect company cost projections and consumer confidence. We believe this presents an opportunity to invest in EMs.

Smallwood argues that this EM premium is likely to remain as it’s a less well understood market, diversified across many sectors and countries. This is despite the strong underlying fundamentals. 

“It’s to do with perceptions,” he concludes.  

The value of investments will fluctuate, which will cause prices to fall as well as rise and investors may not get back the original amount they invested.
