U.S. credit rating slashed! Markets rallied last week, but can stocks keep climbing? Dive into the risks and retail earnings to watch...

Financial market analysis from 19/05/2025. Market conditions may have changed since publication.

Have you ever watched a house of cards wobble, wondering if it’ll collapse or somehow hold steady? That’s the vibe in Ascendant Markets has captured that feeling perfectly this past week. A downgrade in the U.S. credit rating sent shockwaves through financial circles, raising questions about what it means for stocks, bonds, and your portfolio. I’ve been glued to the market updates, and let me tell you, it’s been a wild ride.

Why the U.S. Credit Downgrade Matters

Last week, a major ratings agency dropped the U.S. sovereign credit rating from its top-tier status to the second-highest level, Aa1. Why? They pointed to the growing burden of financing the federal government’s ballooning deficit and debt. It’s like your credit score taking a hit because you’ve maxed out too many cards—only this time, it’s Uncle Sam.

The downgrade reflects the fiscal challenges of a nation spending beyond its means.

This isn’t the first time the U.S. has been knocked down a peg. Two other major agencies made similar moves in 2011 and 2023, but the sting still hurts. A lower rating signals to investors that U.S. Treasurys—those “safe” government bonds—might not be as bulletproof as they thought. And when trust wanes, investors often demand higher yields to compensate for the perceived risk.

How Treasury Yields Affect Your Investments

Rising Treasury yields are like a ripple in a pond—they touch everything. Higher yields make borrowing more expensive for companies, which can crimp corporate profits and weigh on stock prices. For everyday investors, this could mean a bumpier road for your 401(k) or brokerage account.

  • Increased borrowing costs: Companies face higher interest rates on loans, squeezing margins.
  • Valuation pressure: Stocks, especially growth stocks like tech, look less attractive when bond yields climb.
  • Portfolio rebalancing: Investors may shift from stocks to bonds for better returns.

But here’s where it gets tricky: markets don’t always react the way you’d expect. Despite the downgrade, U.S. stocks actually surged last week. What gives?

The Surprising Stock Market Rally

Against all odds, Wall Street threw a party last week. The S&P 500 jumped 5.3%, the Dow climbed 3.4%, and the Nasdaq? A whopping 7.2%. Tech darlings like Tesla and Nvidia led the charge, soaring 17% and 16% respectively. The catalyst? A 90-day trade truce between the U.S. and China, with both sides agreeing to pause tariff hikes.

It’s like the markets were so relieved about dodging a trade war bullet that they shrugged off the credit downgrade—for now. But I can’t help but wonder: is this rally built on solid ground, or is it just a sugar high?

Markets can stay irrational longer than you can stay solvent.

The trade truce is a big deal, no doubt. Tariffs are essentially taxes on goods, and rolling them back eases pressure on companies and consumers alike. But 90 days is a short window, and if negotiations stall, we could be right back to square one.

Tech Stocks: Riding High but Facing Risks

Tech stocks were the belle of the ball last week, but they’re not out of the woods. Take Nvidia, for instance. The chipmaker’s stock soared, yet it’s grappling with U.S. export restrictions on sending advanced chips to China. Why does this matter? Because China’s AI sector is no slouch—it’s projected to hit $50 billion in three years.

Losing access to that market would be, in the words of Nvidia’s CEO, a “tremendous loss.” And it’s not just Nvidia. Any tech firm with exposure to China is walking a tightrope as geopolitical tensions simmer.

So, while tech stocks are basking in the glow of last week’s rally, they’re not immune to the broader pressures of the downgrade and global trade dynamics.

Retail Earnings: A Window into Consumer Health

This week, all eyes are on retail giants like Home Depot, Target, and TJX. Their earnings reports will be like a stethoscope on the American consumer’s heartbeat. Are people still spending, or are they tightening their belts?

Retailers have been navigating a tricky landscape. On one hand, the trade truce could boost consumer confidence. On the other, rising yields and potential inflation might make shoppers think twice before swiping their cards.

  1. Home Depot: Watch for housing market signals—higher interest rates could cool demand.
  2. Target: Gauges middle-class spending; tariffs could hit their low-price model.
  3. TJX: Off-price retail may shine if consumers hunt for deals.

Personally, I’m curious to see if these retailers lean on AI-driven marketing to juice sales. Speaking of which…

AI’s Growing Role in Retail and Beyond

Across the Pacific, Chinese companies like Alibaba and Tencent are showing how AI is revolutionizing advertising. Click-through rates for online ads are soaring—hitting nearly 3% in some cases, up from a measly 0.1% for old-school banner ads. That’s a game-changer for retailers looking to stretch their marketing dollars.

AI is turning ads into precision-guided missiles for consumer wallets.

Here in the U.S., retailers are taking notes. Target, for example, has been experimenting with AI to personalize offers. If their earnings show a bump in sales, you can bet AI played a role. But there’s a flip side: as AI gets smarter, so do privacy concerns. Will consumers embrace the tech or push back?

Global Moves: Ceasefires and Geopolitics

Markets don’t exist in a vacuum, and global events are adding another layer of complexity. The U.S. is pushing for a ceasefire between Ukraine and Russia, with talks reportedly set for this week. Meanwhile, efforts are underway to cool tensions between India and Pakistan. These diplomatic moves could stabilize markets—or throw them into chaos if they fail.

Geopolitical stability is like oxygen for investors. When tensions ease, risk appetite grows, and stocks tend to rally. But if these ceasefire talks hit a snag, expect volatility to creep back in.

In my experience, markets hate surprises. Any hint of progress—or backsliding—in these talks will move the needle.

What’s Next for Investors?

So, where do we go from here? The credit downgrade is a wake-up call, but it’s not a death knell. Markets have weathered these storms before, and they’ll do it again. The key is to stay nimble and keep an eye on the big picture.

  • Monitor yields: Rising Treasury yields could signal trouble for stocks.
  • Watch retail: Earnings will reveal if consumers are still spending.
  • Track geopolitics: Ceasefire talks could sway market sentiment.
  • Diversify: Spread your bets to cushion against volatility.

Perhaps the most interesting aspect is how interconnected everything is. A downgrade in the U.S. ripples to China’s AI boom, which ties back to your local Target store. It’s a reminder that investing isn’t just about picking stocks—it’s about understanding the world.


As I wrap up, I can’t shake the feeling that we’re at a crossroads. The markets are buzzing with optimism, but cracks are forming beneath the surface. Will the rally hold, or will the downgrade’s aftershocks take their toll? Only time will tell, but one thing’s for sure: it’s never a dull moment in the world of finance.

There is risk in every investment. Cryptocurrencies are very volatile, but that risk is offset by the possibility of massive returns.
