Something unusual happened on February 20, 2026. The Supreme Court ruled 6 to 3 that the International Emergency Economic Powers Act does not authorize tariffs. In plain terms, the Court struck down the legal basis for most of the broad tariff regime that had been reshaping trade policy. The Trump administration responded by imposing a 10% tariff under a different law, Section 122, on roughly $1.2 trillion worth of imports.
You are probably wondering what any of this has to do with your certificate of deposit.
The answer is more direct than most people realize. Tariffs affect inflation. Inflation affects what the Federal Reserve does with interest rates. And what the Fed does with interest rates affects what you earn on a CD. The chain is not complicated, but it rarely gets explained end to end for savers who are just trying to figure out whether now is a good time to lock in a rate.
So let’s walk through it.
The Tariff to Inflation to CD Rate Chain
Here is how it works in sequence.
When the government imposes tariffs on imported goods, businesses face higher costs. Most pass those costs on to consumers in the form of higher prices. That pushes up inflation. The Federal Reserve’s job is to keep inflation near 2%. When inflation rises above target, the Fed typically slows or pauses rate cuts, because cutting rates when prices are rising would make inflation worse.
That last part matters for CD savers. The Fed has been cutting rates since September 2024. Three cuts in late 2025 brought the federal funds rate down to 3.50% to 3.75%. CD rates followed those cuts downward. The expectation heading into 2026 was that rates would keep falling, with most forecasts pointing to another cut or two during the year.
Tariffs complicate that picture. Goldman Sachs estimated that tariffs caused inflation to rise by about half a percentage point in 2025. Prices that were broadly falling are now under upward pressure again. The American Bankers Association’s Economic Advisory Committee, which includes chief economists from major US banks, flagged that the Fed is likely to face serious challenges returning inflation to its 2% target specifically because of tariff effects.
| The practical result for CD savers: tariff-driven inflation gives the Fed a reason to pause rate cuts longer than previously expected. That means CD rates may not fall as fast as forecasters predicted at the start of 2026. Rates that looked temporary in January may end up being available longer. |
Two Possible Scenarios and What Each One Means
The honest answer is that nobody knows exactly how this plays out. The Section 122 tariff is scheduled to expire after 150 days. New trade investigations are ongoing. The situation is genuinely uncertain. But there are two distinct scenarios worth thinking through, because each one points to a different decision for savers.
Scenario 1: Tariffs Push Inflation Up, Fed Stays Put
If tariffs keep prices elevated and inflation stays above 2%, the Fed holds its rate steady or moves very slowly. Banks follow suit and keep CD rates competitive to attract deposits. In this scenario, the rates available today could remain roughly where they are for several more months. Locking in now at 4.00% or higher is not urgent in the sense that the rate will vanish tomorrow, but it protects you against the eventual decline that will come once inflation normalizes.
This scenario also means your real return (APY minus inflation) shrinks. If you earn 4.00% on a CD but inflation is running at 3.50%, your purchasing power is only growing by about 0.50%. CDs are still worth holding in this environment because they beat cash and savings accounts by a wide margin, but the real return math is less favorable than it looks on paper.
Scenario 2: Tariffs Tip the Economy Toward Recession, Fed Cuts Fast
The other scenario is more disruptive. Tariffs raise costs for businesses, reduce consumer spending, and slow economic growth. If growth slows enough to tip toward recession, the Fed cuts rates aggressively to stimulate the economy. In this scenario, CD rates fall quickly and significantly. The window to lock in anything above 4.00% could close in a matter of months.
This is the scenario where savers who acted early in 2026 will look back and feel good about it. A 2-year CD opened at 4.00% today keeps paying 4.00% regardless of what happens to the federal funds rate. If rates drop to 2.50% by the end of the year, which is not the base case but is within the range of possibility, that locked rate looks very different in hindsight.
| The key point: Both scenarios favor opening a CD sooner rather than later. In Scenario 1, you earn a solid rate that holds for a while. In Scenario 2, you lock in before rates fall faster than expected. The case against opening a CD would require rates to somehow rise significantly from here, which would need the Fed to start hiking again. Almost no forecaster currently expects that. |
What the Numbers Look Like Right Now
As of April 2026, here is where competitive CD rates stand across major term lengths at online banks and credit unions:
| Term | Best Available APY | FDIC National Average | Gap |
| 3 months | 4.15% | 1.28% | 2.87% more |
| 6 months | 4.33% | 1.47% | 2.86% more |
| 12 months | 5.11% | 1.52% | 3.59% more |
| 2 years | 4.20% | 1.49% | 2.71% more |
| 5 years | 4.15% | 1.34% | 2.81% more |
The gap column is what matters most. Regardless of which tariff scenario plays out, the difference between what most people are earning at traditional banks and what is available at competitive online institutions is enormous. That gap exists independently of Fed policy. It is a structural feature of how online banks compete.
Use the calculator at highyieldcdcalculator.com to see what these rates mean in dollar terms for your specific deposit. Enter your amount at 4.00% APY for a 1-year or 2-year term, then compare it against what your current savings account pays. The dollar difference is usually the most convincing argument.
The Specific Tariff Risk Most Savers Are Not Thinking About
Here is the part that most coverage misses entirely.
The Section 122 tariff that replaced the struck-down IEEPA tariffs is scheduled to expire after 150 days. That puts the expiration date around late July 2026. What happens at that point is genuinely unknown. The administration could let it expire, renew it, replace it with something else, or negotiate new trade agreements that change the picture entirely.
Each of those outcomes has different inflation implications, which have different Fed implications, which have different CD rate implications. The one common thread across all of them is uncertainty. And in an uncertain rate environment, locking in a guaranteed return becomes more valuable, not less.
A CD does not care about tariff policy. Once you open one, your rate is fixed for the full term. The bank is contractually obligated to pay you that APY regardless of what the Fed does, what tariffs do to prices, or what happens at the next FOMC meeting. That is precisely the feature that makes CDs useful when the economic outlook is murky.
How to Think About This With the Calculator
The High Yield CD Calculator at highyieldcdcalculator.com lets you model any of these scenarios directly. Here are three calculations worth running:
Calculation 1: What you earn at today’s rate
Enter your deposit amount, 4.00% APY, and a 2-year term. That gives you your baseline. This is the return you can lock in today before any further Fed decisions or tariff developments.
Calculation 2: What you earn if rates drop 0.50%
Run the same deposit at 3.50% APY for 2 years. The difference between these two results is what waiting through one or two more Fed cuts could cost you in real dollars.
Calculation 3: What you earn if inflation stays elevated
Take your projected interest earnings from Calculation 1. If inflation runs at 3.00% during your CD term, subtract that percentage from your APY to get your real return. A 4.00% APY CD in a 3.00% inflation environment gives you roughly 1.00% real growth. That is still better than keeping money in a checking account, but it changes how you might think about term length.
| One practical note: If you are uncertain about the inflation outlook and do not want to commit to a 5-year term, the current rate environment actually makes short-term CDs attractive. A 12-month CD at 4.15% to 5.11% APY lets you lock in a strong rate now while keeping the door open to reassess when economic conditions become clearer. |
The Bottom Line
Tariffs have introduced genuine uncertainty into the 2026 economic outlook. That uncertainty works in opposite directions for different financial products. For stocks, it creates volatility and risk. For CDs, it creates a case for locking in a guaranteed return while one is available.
The two scenarios that could play out, sticky inflation keeping rates elevated or tariff-driven slowdown pushing rates down fast, both point toward opening a CD sooner rather than waiting. What varies between them is how urgent the timing is, not whether the decision itself makes sense.
The rates available right now at competitive online banks are several times the national average and represent levels that have not been common for most of the past decade. Whether tariff pressures push them higher, lower, or sideways from here, those rates exist today. The calculator shows you exactly what they are worth for your deposit.
