President Trump's trade war has led to even bigger trade deficits with China, even though it was intended to improve the trade balance. But it's not just China — the deficit has increased with most of our other major trade partners, too.

Why it matters: While economists agree that trade deficits aren't a good way to measure a trade relationship, they are the metric Trump fixates on, made campaign promises about and uses to evaluate relationships with other countries.

Throughout his campaign, Trump vowed that he would wipe away the U.S.'s trade deficits: "You will see a drop [in the trade deficit] like you’ve never seen before.”

Reality check: Among the U.S.'s 15 biggest trading partners, the trade balance has moved in the wrong direction for Trump in 10 of those countries between 2016 and 2018, while the aggregate trade deficit has jumped from $503 billion to $628B.

While Trump can explain the deficit spike with China as a short-term sacrifice for long-term benefit, it doesn't account for the wider trend.

The latest: The U.S. trade deficit in the first 6 months of 2019 is even bigger than in the last two years.

What's going on: Trump's tax cuts are as much to blame for the increase in the trade deficit as anything else, writes Axios Markets editor Dion Rabouin:

More money in Americans' pockets leads to more consumption, often of Chinese-made goods.

The tax cut helped boost the value of the dollar, which makes imports to the U.S. relatively cheaper.

The big picture: Trade deficits mean we buy more from a country than they buy from us, but that doesn’t necessarily mean the relationship is unfair, writes Axios business editor Dan Primack.

For example, you have a “trade deficit” with your local grocery: you give them money and get food in return.

Between the lines: Despite the dubious merit of the trade deficit as a useful barometer of the health of a trade relationship, Trump's obsession with the number has led to strained relations with key allies.
