On Friday, talks aimed at averting new high US tariffs on Canada ended without resolution.

Following the collapse of the negotiations, Canada announced that it would impose retaliatory tariffs on US goods on 8 September.

Both sides are blaming each other and appear to be preparing for a trade war.

Canadian Prime Minister Mark Carney said: “When you are attacked, you are at war. We have been attacked.”

Meanwhile, President Trump said on Truth Social: “Canada wants all the advantages of being a State, without being one!!!”

With no agreement reached, the US followed through on its threat to impose new 50% tariffs on $20 billion worth of Canadian goods.

The annual value of Canadian exports to the US stands at around $382 billion.

Although the new import duties primarily target the forestry, alcoholic beverage, dairy, and textile sectors, the affected products range from hockey sticks to dog collars and fake moustaches.

Canada has not yet released the list of products subject to retaliatory tariffs.

However, Carney pledged to retaliate on a dollar-for-dollar basis with the tariffs imposed by the US.

Carney stated that Canadian tariffs would also target similar sectors.

The US and Canada have a long history as allies and trade partners. However, when Trump imposed sweeping tariffs globally, Canada was one of the few nations to retaliate.

Ottawa adopted a “tough stance” by imposing retaliatory tariffs, while Canadians boycotted US-origin alcoholic beverages and travel.

Trump used an untested legal authority to impose the latest tariffs and has also repeatedly raised the prospect of making Canada the 51st state.

The USMCA (North American Free Trade Agreement), negotiated by Trump with Canada and Mexico during his first presidential term, is due for review, and the current trade dispute indicates that this process will be contentious.

The US national debt has reached a record $40 trillion as borrowing expanded at a historic pace.

The development has heightened investor concern over the state of US public finances, despite Donald Trump’s pledge to bring spending under control.

Gross federal debt crossed the threshold on Tuesday, according to Treasury Department data published on Wednesday.

Calculations by the Financial Times show that debt climbed by $3 trillion over the past year, registering the fastest rate of increase in history outside the pandemic period.

Marc Goldwein, senior policy director at the Committee for a Responsible Federal Budget think tank, said:

“This is like a giant, flashing ‘check engine’ light. It doesn’t mean your engine will melt down tomorrow, but it is a clear sign that things have gotten quite out of hand. And it’s not just the size of the number; it’s the speed at which we’ve reached it.”

The US national debt has surged over the past two decades, climbing from below $6 trillion at the start of the century (about $12 trillion in 2026 dollar terms) as massive public spending during the financial crisis and the Covid-19 pandemic compounded enormous budget deficits.

In the past 10 years alone, the total debt load has doubled. Debt held by the public—a key gauge tracked by markets that excludes intra-governmental holdings—now exceeds $32 trillion, roughly equal to the size of the US economy.

The non-partisan Congressional Budget Office expects debt held by the public to surpass the post-Second World War record of 106% of GDP by the end of the decade and to reach 120% by 2036.

As borrowing increased, investors began demanding a higher premium to hold US bonds.

This has driven interest rates higher, leaving debt servicing costs larger than national defence spending.

The situation has created unease in Washington. On Wednesday, prior to the release of the debt data, the Treasury Department announced it would double its buybacks of long-term government debt in a bid to halt a recent sell-off.

Last week, the US paid its highest borrowing costs since 2001 to sell 30-year bonds.

Wednesday’s 10-year Treasury auction produced the highest yields since 2007 as investors fretted over the scale of the debt.

Ed Yardeni, president of Yardeni Research, said: “That is an awful lot of money being borrowed. It is going to feed on itself with interest expenses. If interest rates rise because of concerns about the high debt load, that will lead to even more interest expense. It’s a vicious cycle.”

Trump returned to office in 2025 promising to rein in “wasteful” government spending.

Treasury Secretary Scott Bessent pledged to reduce the budget deficit to 3% of GDP by the end of Trump’s term.

However, measures to trim spending in some areas were offset by broad tax cuts in the president’s signature 2025 fiscal legislation, the “One Big Beautiful Bill”, which will add more than $4 trillion to the debt by 2034.

Trump also requested an increase of more than 50% in annual defence spending, seeking $1.5 trillion in the largest budget request in US history.

The deficit fell to 5.9% of GDP in 2025 from 6.3% the previous year. The CBO expects the deficit to decline to 5.8% this year. The US national debt comprises years of accumulated deficits compounded by interest charges.

Analysts noted that both US political parties missed opportunities during periods of economic expansion to take significant steps toward curbing spending.

Calculations by the Congressional Joint Economic Committee indicate that over the past year, total national debt grew by roughly $7.9 billion a day, or approximately $91,000 per second.

Budget specialists said they hoped crossing the $40 trillion threshold would spur politicians from both parties to take meaningful steps to bring borrowing back under control.

Michael Peterson, head of the Peterson Foundation, a think tank dedicated to returning debt to a sustainable trajectory, said:

“My hope is that this serves as a national alarm and wake-up call to address our fiscal future. If we keep borrowing this much, we are going to face a day of reckoning in financial markets… People will wake up one day and decide: ‘You know what? I’m more worried about the United States now. I’m going to demand higher interest rates, or I’m going to put my money somewhere else.'”

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.
