Is the US making $2 billion a day on tariffs?
No.
The extremely high tariffs (announced on April 2) take effect only on April 9. (What you call the "blanket 10% rate" took effect on April 5.) The Trump quote is from April 8 and uses the present continuous, implying that the US was already "making $2bn a day in tariffs" even before the April 9 tariffs took effect.
Trump (2025-04-08, YouTube):
The tariffs you've been hearing about, ... taking in almost $2 billion a day in tariffs, $2 billion a day, and we're doing very well.
Your question was also posted before April 9 midnight US Eastern Time and uses the present continuous.
So, you're asking about whether the US was making $2 billion a day on and prior to 2025-04-08.
And the answer is "No". Congressional Research Service (2025-01-31):
In FY2024, ... CBP collected $77 billion in tariffs
That's about $0.21B per day.
Trump did increase tariffs on Canada, Mexico, and China prior to April 9, but these alone would've been nowhere near enough to increase tariffs ten-fold.
CBP (2025-04-08):
CBP has successfully implemented 13 tariff-related presidential actions during this Administration and each day collects over $200 million in additional associated revenue.
(The "13 tariff-related presidential actions" refer to the tariffs that took effect before April 9.) Assuming this is true and taking the earlier figure of $0.21B a day, that brings the daily tariff take to $0.41B a day, still far short of the claimed $2B a day.
If not, is there evidence for where Trump pulled this number from?
I have none.
We can ask a separate and different question (this might have been the question you actually wanted to ask):
Will the US make $2 billion a day on tariffs from April 9?
Answer: Also no.
Bloomberg (2025-04-08):
All of the tariffs Trump has imposed, along with those he has threatened, since January would generate around $300 billion in annual revenue on average, according to an analysis from Bloomberg Economics. That’s at the low end of the range, with Treasury Secretary Scott Bessent having floated a figure of up to $600 billion.
Bloomberg (2025-04-04):
Treasury Secretary Scott Bessent has said the tariffs could bring in anywhere from $300 billion to $600 billion a year.
"$300 billion in annual revenue" equals about $0.82B per day, while "$600 billion" equals about $1.6B per day.
So, even the high and optimistic estimate by Bessent falls short of Trump's $2B a day.
Some other estimates:
- The Committee for a Responsible Federal Budget (2025-04-07):
we estimate the reciprocal tariffs could generate roughly $100 to $200 billion through the rest of Calendar Year (CY) 2025 if they remain in place and $1.8 trillion through Fiscal Year (FY) 2034 if they are made permanent.
TPC estimates Trump’s taxes on imported goods would raise about $3.3 trillion from 2026-2035, plus an additional $190 billion for the remainder of 2025, roughly half of Navarro’s prediction.
Note that the above estimates may not even take into account the likely possibilities of massive retaliation by other countries (already starting to take place with China) and a deep global recession.
- The Committee for a Responsible Federal Budget:
the negative economic feedback could be significantly larger if tariffs lead to a recession, economic warfare, or loss of confidence by markets.
TPC’s analysis includes the effects of lower income and payroll tax revenues. However, it does not estimate the effects of retaliation or how much an expected decline in corporate profits and wages would slow the economy. If it did, tariff revenues would be even lower.
Note added on 2025-04-10
On 2025-04-09, after all of the above text was written, Trump backtracked and announced a 90-day pause to the dramatically higher tariffs that were due to take effect on 2025-04-09—with the important exception of China, on which he imposed tariffs of 125% because according to Trump,
They were very disrespectful. They didn't respond right. They retaliated.
The Financial Times (2025-04-10):
The US now has a 10 per cent baseline tariff on imports from all countries ...
Autos and auto parts also dodged the 10 per cent levy — but they remain subject to a separate 25 per cent tariff introduced by Trump last month.
(I'm not sure if for some hours on 2025-04-09, the tariffs might actually have been in effect and enforced and collected by CBP.)
Given the now dramatically lower tariffs (than those that were supposed to take effect on 2025-04-09), it is clear (from the above information and arguments) that at least for the next 90 days (and almost certainly even after), US tariff revenue will not be anywhere near $2B/day.
