S&P 500 Clubbed Lower by Wall Street Bear Upset Over Bigger National Debt

The upward momentum of the S&P 500 (Index: SPX) reversed in the previous week. The index fell 2.6% to close out the trading week ending on Friday, 23 May 2025 at 5,802.82.

Figuratively speaking, Wall Street bears clubbed the index lower because of a politics-oriented event. The stage for that action was set late in the preceding week after Moody's Investor Service finally got around to stripping the U.S. government of its AAA credit rating, becoming the third of the three major firms that rate the creditworthiness of governments to do so. Standard and Poor took that action in August 2011 and Fitch Ratings did the same in August 2023. Moody's action was long-expected because outlook on the U.S. government's fiscal health turned negative in November 2023.

With investors' nerves sensitized to the prospect for higher interest rates that come from the U.S. government getting a lower credit rating, the progress of the "One Big Beautiful Bill" toward passage on Wednesday, 21 May 2025 jolted them. Interest rates jumped and stock prices fell as the projected deficit associated with the spending package was larger than expected. The bill would go on to pass in the narrowly divided House of Representative early in the morning of Friday, 23 May 2025.

But the bigger news was President Trump's threatened 25% tariff on goods imported to the U.S. by Apple (NASDAQ: AAPL), which knocked the S&P 500's largest component stock lower on the day, taking the index lower by a smaller percentage along with it.

The total negative change in stock prices however wasn't large enough to move the trajectory of the S&P 500 outside the redzone forecast range on the alternative futures chart. Here's the latest update of the chart:

Alternative Futures - S&P 500 - 2025Q2 - Standard Model (m=+4.0 from 24 Feb to 8 Apr 2025, m=+1.0 from 9 to 25 Apr 2025, m=-2.0 from 28 Apr 2025) - Snapshot on 23 May 2025

We're continuing to monitor the S&P 500's trajectory with respect to the dividend futures-based model's projections to see if we might be on the cusp of a new market-regime-changing volatility event.

All in all, it's very rare to see a political event outside a change in tax rates produce a noticeable effect in stock prices, but an event that changes interest rates would be capable of the feat. Even so, the magnitude of the effects observed on each of the days they occurred don't even qualify as interesting in the context of the market's typical day-to-day volatility.

Here are the week's market-moving headlines.

The CME Group's FedWatch Tool showed no meaningful change from last week. It projects the Fed will avoid cutting the Federal Funds Rate until the conclusion of its 17 September (2025-Q3) meeting, at which time, it will cut rates by a quarter percent to a target range of 4.00-4.25%. After that, the FedWatch Tool forecasts the Fed will reduce U.S. interest rates a quarter point at a time at twelve-week intervals, coming after it meets on 10 December (2025-Q4) and 18 March (2026-Q1).

The Atlanta Fed's GDPNow tool projection of real GDP growth in the U.S. during the current quarter of 2025-Q2 remained steady at +2.4%, with no updates in the past week. The next update will come on 27 May 2025.
