AI boom creates analytical challenge for central banks as surging spending meets import offsets

Published

on

As massive investments in artificial intelligence continue unabated, the contribution of these outlays to the US economy and their precise impact on productivity remain subjects of intense debate.

The AI boom is heavily reliant on huge imports of hardware that the United States does not manufacture domestically.

This dynamic creates an unusual disconnect between the sheer scale of investment activity and the way it is reflected in official statistical releases, particularly GDP.

In this context, not all capital expenditures are reflected equally in GDP metrics. The construction of AI infrastructure relies heavily on imported semiconductor chips, servers, and networking hardware.

Consequently, a significant portion of the investment surge is offset in government growth calculations.

Artificial intelligence does not possess its own distinct, comprehensive category within official statistical frameworks. This obliges economists to infer its contributions from baseline investment and trade classifications.

In a paper published this month, Federal Reserve economists Paul Soto, Mason Thieu, and Jeffrey Allen wrote:

“The lack of a dedicated category for AI-related investment in national accounts, combined with the high import content of the equipment driving infrastructure buildouts, presents a heightened challenge in precisely measuring how much recent GDP growth has been powered by AI-related capital spending.”

The US economy expanded at an annualized rate of 2.1% in the first quarter. Federal Reserve economists estimate that AI expenditures—comprising capital outlays in software, data centers, energy infrastructure, and computing hardware—contributed approximately 0.73 percentage points to GDP growth.

However, the estimated contribution of AI investments would have been substantially larger were it not for the counterbalancing drag generated by imported AI components.

Net imports of computers, peripheral equipment, and components alone subtracted 0.45 percentage points from headline growth.

US AI import shares expand papidly

According to research by Minneapolis Fed economist Michael Waugh, AI-related products accounted for 23% of total US imports in 2025, up from 15% in 2023.

Computer hardware constitutes roughly half of these incoming shipments.

The remainder consists of electrical equipment, networking hardware, and cooling systems essential to building and operating AI data centers.

The Trump administration largely exempted many of these AI-related inputs from broad-based tariffs.

The interplay between AI capital outlays and trade dynamics was particularly pronounced in late 2025. Corporate entities funneled enormous capital into AI hardware during the final three months of the year, but once imports were factored into the equation, the net boost to GDP was largely erased.

Federal Reserve economists noted that the net impact of AI investments “varied significantly across quarters, as sharp import spikes in certain periods produced a negative contribution from net exports of computers, peripherals, and parts that offset the bulk of gross capital expenditure.”

Net imports exert drag on headline growth

Federal Reserve economists estimate that AI infrastructure investments added just 0.14 percentage points to GDP, even though top-line expenditures in relevant categories contributed roughly 0.75 percentage points prior to accounting for trade flows.

Net imports of AI equipment reduced overall GDP growth by 0.61 percentage points over the period.

Economists project that the economy expanded at an annualized rate of 1.8% during the April-June quarter. The official report will be released today (July 30).

Goldman Sachs anticipates a rebound in consumer spending alongside continued strength in corporate capital outlays driven by AI equipment expenditures.

The AI expansion is simultaneously forcing economists to re-examine traditional methodologies for measuring the broader economy.

Because growth is increasingly anchored in imported hardware and intangible software assets, conventional indicators of broader economic activity are becoming harder to interpret.

The productivity question: Capital utilization over AI adoption

Artificial intelligence appears to be enhancing worker productivity across a range of industries, and the US economy as a whole has recorded a notable productivity gain over the past few years.

However, it is far from certain that the former is directly driving the latter. A controversial new analysis indicates that companies are extracting more hourly output per worker not through widespread AI adoption—at least for now—but through more efficient utilization of existing capital assets.

According to Ernie Tedeschi, chief economist at Stripe, AI advancements may be yielding meaningful micro-level gains in specific sectors, but they have not served as the primary catalyst behind one of the most significant macroeconomic trends of recent years.

After decades of sub-par gains, the recent acceleration in labor productivity has stood out as one of the most positive developments for the US economy over the past few years.

Tedeschi noted that output per hour worked increased by 2.5% over the past year, compared to an average annual growth rate of 1.6% over the preceding two decades.

While that difference might appear modest, if sustained over even a few years, it compounds into a powerful effect, driving per-worker income and output to substantially higher levels.

However, Tedeschi found that while labor productivity has risen, total factor productivity—which measures output per unit of combined labor and capital inputs—remained virtually unchanged.

Examining performance across sectors, he observed that industries with high AI adoption did exhibit higher productivity growth, but that trend actually predated the pandemic—well before advanced large language models (LLMs) entered widespread commercial deployment.

Instead, Tedeschi concluded that higher output has been driven by more intensive and efficient utilization of existing capital stock.

Tedeschi wrote:

“Consider factories already built running longer hours, fully amortized server racks and GPU clusters being driven harder, or existing hotel rooms achieving higher occupancy rates. Economists refer to this as ‘capital intensity’ or ‘utilization rate.’ Higher capital utilization represents real economic gains, but it is fundamentally distinct from micro-level technological efficiency.”

In statements to Axios, Tedeschi said the US is in a period of elevated productivity growth and that it is increasingly plausible AI plays a role, but added a note of caution:

“We must remain realistic about how AI fits into this process, because doing so helps us discern whether AI represents a temporary fluctuation along the growth trajectory or a more permanent, transformative shift.”

AI boom complicates central bank strategy

While central bankers operate under mandates to preserve price stability, foster full employment, and maintain financial stability, the AI boom introduces fresh complexity across all three domains.

A report by the Bank for International Settlements (BIS) indicates that AI is blurring the traditional signals central bankers rely on to formulate monetary policy.

According to the BIS, the technology is simultaneously influencing both the supply and demand sides of the economy, triggering structural and cyclical shifts at the same time.

In the United States and other primary hubs of AI innovation, the near-term investment surge has sparked sharp demand for semiconductors and data center infrastructure components.

Concurrently, the stock market rally has inflated paper wealth, further stoking consumer demand. However, concerns persist that a portion of this market valuation may be illusory, raising fears of an AI asset bubble that could eventually burst.

While AI presents a medium-term risk of large-scale labor displacement, empirical evidence that this process has begun remains inconclusive.

Conversely, a scenario in which AI advances unlock substantial productivity gains would represent a favorable supply shock, which would typically be expected to exert downward pressure on inflation.

BIS economists Iñaki Aldasoro, Leonardo Gambacorta, Enisse Kharroubi, and Matthias Rottner wrote:

“The vast uncertainty surrounding the ultimate impact of AI presents distinct challenges for monetary policy and financial stability. First, AI simultaneously impacts demand and supply from both cyclical and structural perspectives. Moreover, these effects vary widely across individual sectors, complicating any assessment of underlying economic trends. Elevated uncertainty heightens the risk of policy missteps.”

Central banks—including the Federal Reserve, which concludes its policy meeting today, as well as the Bank of England and the Bank of Japan, both scheduled to meet tomorrow—are forced to make real-time interest rate decisions based on limited clarity regarding the direction, magnitude, and timeframe of the AI boom’s macroeconomic impact.

Independent US oil firms set to sign output deals in Venezuela

Published

on

Several independent US oil producers are expected to sign production contracts with Venezuela’s state-owned oil company in the coming days.

According to sources who spoke to Politico on condition of anonymity because details of the event have not yet been made public, a signing ceremony involving several small US producers and Petróleos de Venezuela (PDVSA) was scheduled to take place in Houston on Tuesday (18 August) evening.

One source said Venezuela’s oil minister and the head of PDVSA’s exploration division were scheduled to attend the ceremony. Another source added that the event could be postponed until Wednesday morning.

The White House, which did not immediately respond to a request for comment, was not expected to be officially involved in Tuesday’s ceremony.

However, the development follows a visit by senior officials to Caracas in late April, where they signed memorandums of understanding that established the framework for formal production agreements in the country, which holds some of the world’s largest oil reserves.

Despite the tailwind provided by high crude prices, negotiations had stalled over key details such as dispute resolution, while officials in Caracas contended with two devastating earthquakes in June that claimed thousands of lives.

Venezuela’s interim president, Delcy Rodríguez, announced new regulations last month that offer more favourable fiscal terms to international oil companies.

According to an industry source close to the negotiations, the signing of the contracts comes after the Trump administration renewed pressure on Rodríguez to ensure PDVSA concludes agreements with American firms.

The source said these efforts included outreach by Secretary of State Marco Rubio to discuss how increased oil revenues could assist the country following the devastating earthquake earlier this summer.

The source added:

“Delcy reached a renewed awareness that increased oil production is the way to rebuild after the earthquakes and to achieve what her government wants to do for the people suffering from the earthquakes.”

David Goldwyn, president of the international energy consultancy Goldwyn Global Strategies, said investments from independent oil producers and boosting output from existing fields would serve as the “primary source of new oil growth for the next few years” for Venezuela.

“While the oil majors are trying to buy time to see how the political situation clarifies and whether they can cherry-pick the best assets, independent companies can de-risk their projects in the short term,” Goldwyn said.

However, Goldwyn noted that these investments would add no more than 300,000 barrels per day to the country’s oil production over the next year, falling far short of the multi-million-barrel increase that officials in Caracas and Washington wish to see.

“Until the framework improves, electricity is restored, and the political picture becomes clear, all we will see is incremental production growth,” the strategist said.

US-Brazil rift widens over proposed sanctions and trade tariffs

Published

on

Diplomatic tensions between the two countries remain at a peak as the US government considers new sanctions targeting a judge on Brazil’s Supreme Court.

According to sources familiar with the matter who spoke to the Financial Times (FT), the Trump administration is evaluating new measures against Justice Alexandre de Moraes, whom it sanctioned last year on human rights grounds before subsequently rescinding that decision.

Washington’s renewed focus on the magistrate threatens to widen the rift between Brazil and the US across trade and political spheres, casting a shadow over upcoming elections in Latin America’s largest nation.

A little over a year ago, De Moraes was subjected to sanctions under the Global Magnitsky Act. US Treasury Secretary Scott Bessent accused him at the time of engaging in a “repressive censorship campaign, arbitrary detentions that violate human rights, and politicized prosecutions,” including measures directed at former Brazilian President Jair Bolsonaro.

Bolsonaro, an ally of Donald Trump, was sentenced last year to 27 years in prison for plotting a coup.

However, sanctions targeting the judge, his wife, and a company owned by his family were lifted in December following a meeting and phone conversations between Trump and his Brazilian counterpart, Luiz Inacio Lula da Silva.

According to a source familiar with the matter who requested anonymity, US interest in De Moraes was revived partly due to a case that ignited a debate over press freedom in Brazil.

The judge authorized police raids against a journalist and two sources as part of an investigation into media coverage concerning a Supreme Court justice and his family.

De Moraes defended the action, arguing that the information in question had been illegally obtained and disclosed, thereby endangering the safety of the justice’s family.

The judge gained global prominence several years ago following a public conflict with Elon Musk, which briefly led to the billionaire’s X platform being blocked in Brazil.

Supporters say he “helped protect Brazilian democracy against a wave of misinformation.”

However, critics, including the Trump administration, view him as violating free speech rights.

“He went after the president’s supporters. Not just Elon Musk, but MAGA supporters in Brazil as well. Even if we want to build good relations with Brazil, it is clear that this man is an adversary,” said a person familiar with the US government’s thinking.

Another person stated that the reimposition of Magnitsky sanctions is “under evaluation,” noting that such sanctions entail the freezing of US-based assets and a prohibition on American companies and individuals conducting business with targeted parties.

While it remains unclear whether or when a decision will be reached, any such move would intensify an escalating retaliatory spiral between the two most populous countries in the Americas.

Tensions initially erupted more than a year ago when Trump imposed a 50% tariff on Brazil while demanding that prosecution proceedings against Bolsonaro be dropped.

That tariff was subsequently invalidated by the US Supreme Court.

A brief period of de-escalation since then has drawn to a close, with the US applying a 25% import tariff on numerous Brazilian products in July.

Last month, Brazil denied entry to two Trump envoys over concerns regarding potential interference in its upcoming October elections. Washington rejects those allegations.

Lula, who is seeking re-election for a fourth presidential term, suggested that the US might act to support his main opponent, Senator Flavio Bolsonaro, the jailed former leader’s son.

The 80-year-old president has also engaged in a sharp public exchange of words with US Secretary of State Marco Rubio.

On Sunday, thousands of supporters gathered to welcome Lula at a stadium in Sao Bernardo do Campo, an industrial suburb of Sao Paulo, for the official launch of his election campaign.

Lula originally achieved prominence in the area during the late 1970s as a union leader heading metalworkers’ strikes.

Speaking at the venue, Lula said, “I thank the working men and women of this country who believed that someone like themselves could achieve more than someone different from them. As long as I am alive, I will not stop fighting, and I will not allow the right [to prevail].”

AIPAC super PAC pours millions into key Democratic primary races

Published

on

The United Democracy Project (UDP), the super PAC of the American Israel Public Affairs Committee (AIPAC), has directed nearly $2.5 million into a special election for the California seat formerly held by Representative Eric Swalwell, marking one of the group’s final targeted contests ahead of November.

The UDP spent approximately $2.5 million to campaign against state Senator Aisha Wahab, the favourite in the race, and to promote Bay Area Rapid Transit (BART) Board President Melissa Hernandez. The expenditure attracted significant attention, given that Wahab finished well ahead of Hernandez in the June special primary.

AIPAC links have also emerged as a central issue in two Democratic contests in Florida and New Hampshire, among the final states on the 2026 primary calendar. Intra-party friction over the role of money in politics and questions regarding the extent to which US support for Israel should continue remain heavyweight concerns ahead of the November elections.

“I wish that AIPAC would realise that, for better or worse, it has become a lightning rod, and that is helping less, unfortunately, not just themselves, but the cause they advocate for,” said a national Democratic strategist who has previously worked with the UDP.

An AIPAC spokesperson disputed this assessment, pointing out that more than 250 candidates backed by the group have won their primaries.

“Our community of 7 million Americans is focused on helping pro-Israel Democratic and Republican candidates win in November,” the spokesperson added.

UDP spends millions in California’s 14th District

AIPAC’s super PAC is making a multi-million-dollar expenditure in California’s 14th Congressional District, previously represented by Swalwell, who resigned following sexual assault allegations that he denied.

Wahab and Hernandez are facing off in two separate races this year. The first, taking place on Tuesday, will select a representative to complete the remainder of Swalwell’s term. The second race will be held in November for a full two-year term.

Wahab finished 26 percentage points ahead of Hernandez in the special primary. The margin in the primary for the full term was 21 percentage points in Wahab’s favour.

Despite these margins, the UDP has spent roughly $2.5 million to date to boost Hernandez and campaign against Wahab. A separate group called Bold America, which received funds from the UDP and was established by former members of the Congressional Hispanic Caucus, has also spent approximately $1.8 million.

Wahab opposes unconditional aid to Israel. Last year, she introduced a resolution in the California legislature calling for an end to the Israel-Hamas war.

Wahab has also described the war in Gaza as a “genocide”. Hernandez, speaking at a candidate forum this spring, declined to use the same term, though she condemned “the destruction in Gaza”.

Wahab asserted that she has been targeted due to racism and bias.

“Power brokers in Washington also have a need to control every voice on highly critical votes,” Wahab told The Hill. “I have been very clear about my stance on human rights and doing what is best for the American people.”

UDP spokesperson Patrick Dorton, in a statement to The Hill, described Wahab’s assertions as “100% absurd”. Dorton stated that the group supports members of both the Congressional Black Caucus and the Congressional Hispanic Caucus.

Bold America did not respond to a request for comment from The Hill.

Hernandez, in a statement to The Hill, pointed to her campaign’s “thousands of supporters” and said that “no single supporter dictates her agenda”.

“My opponent wants to turn this race into a national issue, whereas the race should actually be about how best to serve the voters in the East Bay and Tri-Valley,” Hernandez said.

The spending in the race attracted particular notice after the UDP spent tens of millions of dollars earlier this month in the Michigan Senate primary to support Representative Haley Stevens, who narrowly lost to progressive candidate Abdul El-Sayed.

“In many cases, as a political operative, my advice was that we shouldn’t get into this specific race, because we would become the issue itself and… we would harm the candidate we were trying to help,” said Garry South, a veteran California strategist who has worked on independent expenditure campaigns in the real estate sector.

“Frankly, I think AIPAC has reached that point,” South added.

FEC complaints surface in California race

The race has intensified in recent days. A supporter of Hernandez filed a complaint against Wahab with the Federal Election Commission (FEC).

According to the complaint, Wahab’s state Senate committee gave money to a county party organisation, which then used a portion of those funds to support Wahab’s congressional campaign. The complaint alleged that external activities supporting Wahab constituted an “illegal and unreported in-kind contribution”.

Wahab told The Hill that her campaign had not received any notice from the FEC. The Alameda County Democratic Central Committee said in a statement that it was aware of the complaint but maintained that its activities complied with “federal election laws”.

“Until the FEC actually takes action, this is nothing more than a political allegation floated by our opponents,” Wahab said.

According to a report by KQED, Wahab’s campaign also plans to file a complaint with the FEC regarding a series of social media posts targeting the candidate, which Wahab characterized as defamatory.

The report stated that the complaint will request an investigation into whether the online activity was conducted in a coordinated manner to influence the election outcome and whether the activity ought to have been officially reported.

AIPAC influence debated in Florida race

The California contest is not the only election on Tuesday where AIPAC’s influence has surfaced as an issue.

Oliver Larkin, an activist and democratic socialist who is an outspoken critic of AIPAC and unconditional US aid to Israel, is running against Representative Jared Moskowitz in Florida’s redrawn 25th Congressional District.

The district, which covers parts of Miami-Dade, Palm Beach, and Broward counties, is viewed as a swing territory that could be won by either party. AIPAC is supporting Moskowitz in the race.

In an interview with The Hill, Larkin pointed to the war in Gaza and AIPAC’s support for “this deeply disastrous foreign policy”. Larkin said the group had also “supported 109 Republican insurrectionists in the 2022 midterms”.

Larkin further noted that the Israel-Hamas war, particularly its disproportionate influence on the 2024 presidential race, sits “at the centre of many struggles within the Democratic Party over the influence of money in politics”.

Halie Soifer, CEO of the Jewish Democratic Council of America, described AIPAC as an “easy target for the far left, especially since the targeting is mutual”.

In an interview with The Hill, Soifer said that some candidates have turned debates over military aid to Israel into “politically convenient talking points”, but added that these do not resonate “everywhere”.

Moskowitz declined an invitation from the Sun Sentinel Editorial Board to participate in a joint interview with Larkin.

“I do not believe it is appropriate to share a platform with a candidate who has repeatedly embraced the support of individuals and organisations that circulate antisemitic rhetoric and hostility toward the Jewish community,” Moskowitz wrote.

Larkin, who has engaged with figures including the controversial leftist Twitch streamer Hasan Piker, acknowledged that such individuals “do not always use the most politically correct language”.

However, Larkin added: “Cherry-picking these statements to equate anti-Zionism with antisemitism does a disservice to the nuanced critique articulated by individuals like Hasan Piker.”

AIPAC backing creates new divide in New Hampshire

Next month’s Senate primary in New Hampshire has also highlighted differing stances within the Democratic Party regarding AIPAC and its allies.

Karishma Manzur, a Democratic scientist, criticized Representative Chris Pappas—the favourite running to replace Democratic Senator Jeanne Shaheen—for taking money from special interest groups, including AIPAC.

Pappas is listed among the supported candidates on AIPAC’s website.

Manzur, who opposes unconditional aid to Israel and has described the war in Gaza as a “genocide”, said: “Any candidate or lawmaker who takes even $1 from corporations or corporate PACs is no longer a public servant; they are merely a contractor for their client.”

Pappas’s campaign maintained that Manzur exaggerated the amount of support the candidate received from AIPAC’s PAC. The campaign also stated that Pappas does not accept donations from corporate PACs and noted that he introduced a bill aimed at limiting election spending by foreign nationals.
