A confluence of developments, including this downgrade, has the potential to move US yields higher.

What happened

Credit rating agency Fitch Ratings downgraded US debt from AAA to AA+ on August 1. Its rationale was “expected fiscal deterioration over the next three years, a high and growing general government debt burden, and the erosion of governance relative to ‘AA’ and ‘AAA’ rated peers over the last two decades that has manifested in repeated debt limit standoffs and last-minute resolutions.”1

How markets reacted

Markets were somewhat surprised and rattled by the decision. The timing was odd, given that it occurred well after the debt ceiling issue was resolved. The downgrade was based on information that has been widely known for some time, so there were no real surprises.

Our take on what happened

The reality is that recent US administrations (Presidents Trump and Biden) learned from the mistakes past administrations made in providing inadequate fiscal stimulus during the Global Financial Crisis. Fiscal stimulus was far greater in response to the pandemic, which resulted in higher debt. Therefore, higher debt levels can be seen as contributing to growth. In addition, while debt-to-GDP (gross domestic product) is very elevated, debt-to-US government assets isn’t a concern.

It’s also important to note that, in my opinion, a downgrade doesn’t typically have a material impact on markets until you get close to a junk rating. So, I believe this is largely irrelevant despite some initial shock. It seems unlikely to me that it’ll have any meaningful impact beyond the very short term.

This downgrade takes the Fitch rating of the US below their ratings for Germany, Switzerland, and Singapore, which all have AAA status. The US rating is the same as that of Canada at AA+. However, the new US rating from Fitch compares favourably to both France and the UK, which have AA- ratings, and Japan, which has an A rating.1

Our outlook on the situation

We believe this downgrade will have no meaningful impact beyond the very near term. US debt was already downgraded by Standard & Poor’s in 2011, with no material impact beyond a very short-term reaction. There have been concerns for many years about US government debt levels. Despite these concerns, over the last three decades, US Treasury yields remained relatively low and the stock market has made significant gains.2

Our resulting investment strategy

We maintain our existing investment views. We anticipate volatility in the near term (the Federal Reserve is still data dependent). We expect some digestion of stock market gains and the potential for a minor pullback in the near term as markets reprice when the Federal Reserve begins to cut rates. We’d expect global risk appetite, however, to start rising later this year as markets ultimately look forward to and discount an economic recovery next year.

What we’re watching out for and the risks to our view

US yields may potentially move higher because of a confluence of developments, including this downgrade. Other developments include the issuance of more US debt (now that the debt ceiling is resolved), and the Bank of Japan’s alterations to its yield curve control policy, which makes Japanese government bonds more attractive for Japanese investors to own than they had previously been (relative to US Treasuries).
