California has officially overtaken Japan to become the world’s fourth-largest economy, according to new data released by the International Monetary Fund (IMF) and the US Bureau of Economic Analysis (BEA). The Golden State’s gross domestic product (GDP) reached $4.10 trillion in 2024, narrowly edging out Japan’s $4.01 trillion.
Governor Gavin Newsom hailed the achievement as proof that California is not only thriving but leading the global economic race.
“California isn’t just keeping pace with the world — we’re setting the pace,” said Newsom in a statement celebrating the milestone.
California’s Economic Powerhouse: Innovation, Agriculture, Ports, and Hollywood
With its diverse economic base, California is a unique economic juggernaut:
- It hosts the nation’s largest manufacturing and agricultural sectors.
- It’s home to Silicon Valley, the epicenter of global tech innovation.
- The state is also the entertainment capital of the world, thanks to Hollywood.
- And it operates the two largest seaports in the United States — Los Angeles and Long Beach — critical to international trade.
California’s rise reflects its broad-based economic resilience, outperforming many nations through its ability to innovate and export across multiple industries.
The Big Picture: Who’s Ahead of California?
As of 2024, only three economies surpass California’s GDP:
- United States – $29.18 trillion
- China – $18.74 trillion
- Germany – $4.65 trillion
But when it comes to growth rate, California is leading the pack, with economic expansion outpacing even Germany, China, and the U.S. overall.
Clouds on the Horizon: Trade War Could Undermine Progress
Despite the record-setting numbers, Governor Newsom voiced serious concerns about the potential fallout from President Donald Trump’s escalating trade war — particularly the wave of tariffs that now threaten global supply chains and local industries.
In his remarks, Newsom criticized the federal government’s trade policy as a threat to California’s continued economic leadership:
“While we celebrate this success, we recognize that our progress is threatened by the reckless tariff policies of the current federal administration,” he said. “California’s economy powers the nation, and it must be protected.”
Newsom, a Democrat and potential 2028 presidential contender, has even taken legal action, filing a lawsuit challenging President Trump’s authority to impose widespread tariffs without congressional approval.
Trump’s Tariffs: Economic Strategy or Global Gamble?
President Trump has imposed sweeping levies under what he calls the “Liberation Day” trade initiative, aimed at reshaping global trade in favor of American manufacturing:
- 10% tariffs on nearly all imports to the U.S., with a 90-day delay on some.
- 25% tariffs on Mexico and Canada.
- Up to 145% import taxes on Chinese goods — and when combined with existing duties, some products face 245% effective rates.
- China has retaliated with 125% tariffs on U.S. exports, setting off a full-blown trade war between the world’s two largest economies.
The Trump administration maintains that these tariffs are necessary to “level the playing field”, bring back U.S. manufacturing jobs, and pressure foreign governments to open their markets.
IMF’s Warning: Tariffs Are Dragging Global Growth
The International Monetary Fund has expressed caution over the unfolding trade policies, especially in Japan, whose economy was overtaken by California this year.
Japan is dealing with a shrinking workforce and ballooning healthcare costs due to its rapidly aging population. The IMF recently cut Japan’s growth outlook and said tariffs are delaying consumer-driven recovery.
“The effect of tariffs announced on April 2 and associated uncertainty offset the expected strengthening of private consumption,” said the IMF in its World Economic Outlook report.
California’s Dilemma: Global Leader, Local Target
California’s economy may be global in scope, but it is also uniquely vulnerable to trade disruptions:
- Agricultural exports to Asia are at risk due to retaliatory tariffs.
- Tech components and electronics rely heavily on international supply chains.
- Ports may see declining throughput if tariffs slow global trade volumes.
This places California at a crossroads: a global economic leader caught in the crossfire of a high-stakes trade war.
The Bottom Line
California’s emergence as the fourth-largest economy in the world is a landmark moment in U.S. economic history. It reinforces the state’s status as a global innovation and trade hub, outperforming entire nations in both scale and speed.
But success brings exposure. And with Washington’s tariff machine in full gear, the state’s prosperity could be the next casualty of geopolitical brinkmanship.
