The word “downgrade” often carries the sting of failure, like a lowered grade on a report card or an alarm bell going off. However, when it comes to sovereign credit ratings, the implications are more nuanced. Last Friday, Moody’s – one of the three major credit rating agencies – made headlines by announcing its decision to downgrade US debt one notch lower, from Aaa to Aa. This means that the United States no longer holds a top-tier rating with any of the three major ratings firms, with each agency citing rising federal debt and mounting interest costs as long-term concerns.
As financial advisors, part of our role is to help clients filter out the noise and remain focused on what actually matters for long-term financial security. That includes ignoring sensationalist headlines related to the US debt downgrade and, like the market, mostly viewing this as old news – after all, it has been more than a decade since S&P Ratings downgraded US debt in 2011, and a few years since Fitch Ratings made a similar move in 2023. That doesn’t mean there aren’t ripple effects from a lower credit rating, but the current downgrade doesn’t meaningfully change the landscape for long-term investors.
What is a Credit Rating, and Why Does it Matter?
A credit rating is essentially a measure of a borrower’s ability to repay their debts. Just as an individual’s credit score affects their ability to get a loan or mortgage, a country’s credit rating affects how it borrows money and at what cost.
Moody’s, along with S&P and Fitch, comprise the “Big Three” rating agencies. They assign letter-grade ratings (like AAA, AA, A, etc.) based on a nation’s economic growth, fiscal policy, current debt burden, and political stability. These scores, or sovereign credit ratings, provide investors with an independent assessment of a country’s creditworthiness and help them understand the level of risk involved in investing in that country’s debt.
So why does this matter? In theory, lower credit ratings can make it more expensive for governments to borrow money, just as a lower credit score may mean higher mortgage rates for an individual borrower. As the US issues new debt or refinances existing debt, investors may demand higher interest rates to compensate for what they perceive as added risk. That said, the US occupies a unique place in the global economy. Treasury bonds are still viewed as one of the safest investments in the world, and investor appetite hasn’t waned much since the initial downgrade in 2011. Keeping this in perspective: Moody’s has 21 notches on their ratings scale, and US government debt is still solidly at the second highest rating level.
What This Downgrade Means for Markets
In the short term, the market reaction has been fairly muted. Stock markets have remained relatively calm, while bond yields initially nudged higher but have already begun retreating back to prior levels. The US dollar also declined incrementally, which provides a small boost to international stocks within our portfolios. Taking a quick look at history, we can see a similar reaction following past downgrades in 2011 and 2023. Initial volatility was short-lived, and in some cases, the downgrade actually led to higher prices for US Treasuries as investors continued to view them as the safest asset in a period of uncertainty.
Despite the limited reaction by markets, the rationale behind Moody’s decision is worth paying attention to. The agency cited “rising political polarization” and “the lack of effective fiscal policy” as key risks, adding that “successive US administrations and Congress have failed to agree on measures to reverse the trend of large annual fiscal deficits and growing interest costs.” In plain terms, they’re concerned that ongoing political gridlock in Washington may continue to undermine long-term fiscal planning. The repeated debt ceiling showdowns, growing deficits, and absence of bipartisan agreement on spending and revenue are all contributing factors.
For investors, these themes are not new. We’ve long known that US debt levels are rising and that fiscal discipline is often abandoned in the name of politics and short-term spending. For long-term portfolios, these structural concerns are worth acknowledging, but they rarely have short-term implications. The downgrade is not a prediction of impending default, nor is it an indication that US Treasuries are unsafe. It is a reminder that ratings agencies have slight concerns about the long-term drag from US debt, which is a prudent thing to be concerned about even if it doesn’t have any imminent impact on the market. It is also worth remembering that since S&P Ratings first downgraded the US credit rating in 2011, investors have benefited significantly from staying in the market and sticking to a long-term financial plan.
Taking the Long View
With 24/7 news cycles and push alerts, it’s easy to get caught up in headlines and worry about what it means for your portfolio. At North Berkeley, we believe that perspective is key. Ratings agencies do serve a role in promoting transparency and accountability, but they don’t have a crystal ball. Their outlooks and ratings are only one piece of a much larger puzzle.
For long-term investors with diversified portfolios and a financial plan, this downgrade does not necessitate a change in strategy. Even amidst the current uncertainty, the US still has resilient capital markets, the global reserve currency, and a strong economy. These foundations remain intact. Diversified portfolios are built to weather periods of uncertainty, and just as we’ve managed through elections, recessions, pandemics, and rate hikes, our portfolios will navigate credit outlook changes, too. For our clients, we continue to focus on actions that are within our control: savings habits, spending decisions, investment discipline, and long-term goals. These are the drivers of financial success – not credit rating headlines.
