We told you to lock in a CD rate before the Fed cuts. That was March. The Fed hasn’t cut once since then — and now the CME FedWatch Tool shows the futures market pricing in something closer to a hike. Roughly 82% odds of one at the September 16 meeting, per the latest CME data. Six weeks ago that number was below 53%. Go back further and it was closer to a coin flip against.

Here’s the uncomfortable part: our own March CD roundup told readers the “window” to lock in 4.20% would close when the Fed cut in September. We were reasoning from the Fed’s own dot plot at the time, which is normally the sane thing to do. Then the Iran war blew a hole in the oil market, and the entire premise flipped. This is the correction.

Quick Take: What Changed Since March

Metric	March 2026	August 2026
Fed funds rate	3.50-3.75% (held)	3.50-3.75% (held)
Sept. 2026 hike odds (CME FedWatch)	Not meaningfully priced	~82%
Top 12-month CD rate	4.20%	Up to 4.50%+
CD rate direction	Falling, “lock in before cuts”	Rising, weekly increases outnumber cuts 5-to-1
Brent crude	~$70s	Above $84/barrel
Dominant savings advice	Lock in before the cut	Reconsider locking in long

What Actually Happened

Start with the Fed meeting itself. On July 29, the FOMC voted 9-3 to hold the federal funds rate at 3.50-3.75% — the fifth straight hold. Three committee members (Beth Hammack, Neel Kashkari, and Lorie Logan) dissented in favor of raising rates a quarter point immediately. That’s not a footnote. Three sitting FOMC members wanted to hike in July, not September.

The trigger is the war. Iran-linked strikes on U.S. forces and shipping disruption through the Strait of Hormuz sent Brent crude above $84 a barrel, up more than 38% for the year. Oil at that level feeds directly into headline inflation, and the Fed’s post-meeting statement explicitly flagged the conflict’s “uncertain” economic implications while noting inflation remains “elevated relative to the Committee’s 2 percent goal, in part reflecting supply shocks… including energy.”

Markets took the hint. CNBC reported odds of a Fed hike surging as oil ripped higher through late July, with September-meeting hike probabilities jumping from below 53% to roughly 82% in the span of about a week. That’s not drift. That’s a repricing.

Why This Matters for a CD Post We Wrote Five Months Ago

Our March piece wasn’t wrong about the data available in March. The Fed’s dot plot pointed to one cut, probably September. CD rates were falling in anticipation. Locking in 4.20% for 12-18 months looked like the obvious move against a falling-rate backdrop.

The mistake — if you want to call it that — was treating a dot plot as a fixed destination instead of a snapshot. Dot plots move. This one moved a lot, and fast, because of a variable (a Middle East oil shock) that wasn’t in the March forecast at all.

If you opened an 18 or 24-month CD in March at 4.00-4.20% expecting to beat a falling-rate market, you’re not in a bad spot — you locked a decent rate and it’s still paying what it said it would pay. But the framing of “lock in before the cut” as urgent, time-sensitive advice doesn’t hold anymore. The cut isn’t the base case right now. A hike might be.

CD Rates Are Already Moving

This isn’t theoretical. CD Valet’s latest weekly tracking recorded 539 existing CD rates increasing against just 105 decreases — nearly 84% of all rate changes were increases. That reverses a trend that had been running the other direction earlier in the year. CD Valet’s own reporting shows the increase share climbing steadily: about 54% of changes were hikes in May, more than two-thirds in June, and now approaching 84% heading into August.

The median CD rate ticked up too — 3.25%, a small but real move in a market where CD rates had mostly been sliding since 2024.

Good CD rates in August 2026 run 3.95% to 4.50% depending on term, with the top end of that range — per Bankrate’s August tracking — actually higher than the 4.20% top rate we cited back in March. Banks aren’t cutting offered rates in anticipation of a Fed cut anymore. Some are raising them in anticipation of a hike.

What This Means If You’re Sitting on Cash Right Now

You’re not too late. The rate environment didn’t collapse — it improved. Top CD rates today beat the top rates from our March roundup. If you’ve been sitting in a high-yield savings account waiting for a better entry point, that entry point may have just arrived.

The “lock in before it’s gone” urgency is gone — for now. In March, the argument for a CD over a HYSA was “grab this rate before the Fed cuts it away from you.” That specific argument doesn’t apply while hike odds sit near 82%. A floating-rate HYSA could plausibly rise alongside a Fed hike, the same way it fell when cuts were expected.

Shorter terms make more sense than they did in March. If you believe the Fed hikes in September — or even just holds through year-end — locking money into a 24 or 60-month CD forecloses on capturing a higher rate a few months from now. A 6 to 12-month CD or a T-bill ladder keeps you closer to the current, rising rate rather than freezing you at today’s number.

Nobody actually knows what happens next. That’s not a cop-out — it’s the honest state of the data. Oil-driven inflation spikes can also break growth, and a war that escalates further could just as easily tip the economy toward the kind of slowdown that eventually forces cuts anyway. The FedWatch odds reflect a probability, not a certainty. Three months from now this post could look as outdated as the March one does today.

Should You Still Open a CD Right Now?

Yes, but hold the term shorter than you would have in March.

1. If you need the money in under a year: A 6 to 9-month CD or a HYSA still makes sense. You’re not giving up much and you keep flexibility to re-lock at a higher rate if the hike materializes.
2. If you have money you truly won’t touch for 2+ years: Rates in the 3.60-4.00% range on longer CDs are still solidly ahead of the national average, and a genuine multi-year lock protects you if this hike cycle proves temporary and cuts eventually resume (which they usually do, eventually).
3. If you’re not sure: Split it. Put a portion in a short CD or T-bill to stay flexible through year-end, and leave the rest liquid in a HYSA until the September meeting actually happens and the FedWatch odds either confirm or reverse.

What to Watch Before September 16

A few data points will move the FedWatch odds meaningfully between now and the meeting:

• Any further Iran war escalation or de-escalation. Oil is the transmission mechanism here. A ceasefire that brings Brent back toward $70 would likely knock hike odds down fast.
• The August and early-September CPI prints. If energy-driven inflation shows up in core CPI, not just headline, that strengthens the case for a hike.
• Jobs data. A weakening labor market gives the Fed room to look through an oil shock. A resilient one, like the 4.2% unemployment rate cited in the July statement, doesn’t.

The Bottom Line

The Fed didn’t hike in July — it held, 9-3, with three governors publicly wanting more. The market thinks September could be different, and it’s put real money behind that view: CME FedWatch odds near 82%, up from roughly half that just weeks earlier. CD rates are already responding, with hikes outnumbering cuts by more than 5 to 1 in CD Valet’s latest read.

If you followed our March advice and locked a rate, you’re fine — you got a real, guaranteed return that’s still paying out. If you didn’t lock anything yet, the calculus has changed: shorter terms, more flexibility, and less urgency to lock in a number before it “disappears,” because the number is currently going up, not down.

We’ll revisit this again after the September meeting. Given how fast this reversed once, we’re not assuming it holds.
