USA & Canada Intelligence Brief August 3 — Key Facts
—Brazil tariff A new 25% US tariff on most Brazilian goods took effect on 22 July, replacing a 50% duty the Supreme Court struck down in February; broad carve-outs soften it and President Lula has gone to the WTO rather than retaliate at once.
—Import average The measured effective US import tariff stood at 7.2% in May 2026, the latest official reading, after February’s Supreme Court ruling voided the emergency-powers duties.
—Wall St rally Amazon’s US$200.6 billion quarter and soaring cloud growth lifted the S&P 500 to 7,489.72 on Friday.
—Water cyberattack An Iran-linked hack struck over 30 Minnesota water systems, triggering a public blame fight between Trump and Governor Walz.
—Canada wildfires Around 800 fires burn across Canada, with 5,000-plus people across British Columbia placed under evacuation orders in one day.
—Trade deadline Canada faces 50% US tariffs on about US$20 billion of goods from 19 August, intensifying urgent trade talks.
USA & Canada Intelligence Brief August 3 — Wall Street celebrated strong gains after Amazon’s cloud-fuelled earnings beat, yet the mood darkened elsewhere as Washington’s new 25% tariff on most Brazilian goods took hold and a tariff wall widened over more than 60 nations. Canada faced a double crisis, racing to dodge looming US duties while roughly 800 wildfires burned and thousands fled their homes.
United States – Brazil tariff reset to 25%
Duties take hold
Washington’s tariff campaign against Brazil has been reset. The original 50% duty — imposed in 2025 over the prosecution of former President Jair Bolsonaro — was struck down by the US Supreme Court in February, which found the emergency-powers law could not justify it. In its place, a 25% tariff on most Brazilian goods took effect on 22 July under Section 301, though Washington exempted most of Brazil’s exports, including coffee, beef, orange juice and Embraer aircraft; a separate forced-labour probe could add a further 12.5%. President Lula has taken the dispute to the World Trade Organization and readied Brazil’s economic-reciprocity law but has so far held back on counter-tariffs, betting on negotiation.
United States – Tariff wall snaps shut
A wider barrier
As Washington’s mid-summer tariff push took hold, fresh duties now cover imports from more than 60 countries. The measured average effective tariff on goods entering the United States stood at 7.2% in May 2026, the most recent US International Trade Commission reading — well below the 2025 peak, because the Supreme Court voided the emergency-powers tariffs in February, but set to climb again as the new Section 301 and Section 338 duties bite.
Trump’s tariff wall is the dominant economic story for both economies, leaving markets euphoric while trade, security and wildfire anxieties mount.
United States – Markets rally as July ends red
Amazon powers a rally
Amazon delivered a blockbuster second quarter, with net sales reaching US$200.6 billion and its cloud division AWS surging 37% to US$42.2 billion. Chief Executive Andy Jassy’s results ignited a rally in the largest technology names that carried the S&P 500 to a close of 7,489.72 on Friday 31 July.
United States – Water-system cyberattack
Security and blame
An Iran-linked cyberattack struck more than 30 municipal water systems across Minnesota in late July, raising urgent security fears. In late July, President Trump publicly blamed Governor Tim Walz for the breach, while Walz accused the president of attempting a cover-up, turning a public-safety crisis into a political clash.
Canada – Wildfire emergency
Flames force thousands to flee
About 800 wildfires were burning across Canada on 3 August, with the Bradley Creek blaze near Okanagan Lake, British Columbia, triggering new evacuation orders. More than 5,000 people across British Columbia were placed under evacuation orders in a single day, deepening a summer of anxious flight from the flames.
Canada – Trade-deal countdown
A mid-August deadline looms
Canada is scrambling to avoid sweeping US Section 338 tariffs of 50% on roughly US$20 billion of goods, set to kick in on 19 August. Prime Minister Mark Carney and President Trump have agreed to intensify negotiations, with the country’s economic security hanging on a deal that must be struck within weeks.
The Bigger Picture
A split-screen moment defines North America: while Amazon’s cloud-driven results pushed the S&P 500 to a strong Friday close, unease spreads beyond the trading floor as Washington resets its Brazil tariff to 25% and widens a tariff wall affecting over 60 nations, while he and Minnesota’s Governor trade blame over a foreign cyberattack on water systems.

Frequently Asked Questions
What tariff does the United States now charge on Brazilian goods?
A 25% tariff on most Brazilian goods took effect on 22 July 2026 under Section 301, replacing the 50% duty the US Supreme Court struck down in February. Washington exempted much of Brazil’s export base, including coffee, beef, orange juice and Embraer aircraft. President Lula has taken the dispute to the World Trade Organization rather than retaliate immediately.
Why did Wall Street rally at the end of July 2026?
Amazon’s second quarter drove it. Net sales reached US$200.6 billion and the AWS cloud division grew 37% to US$42.2 billion, igniting a rally in the largest technology names. The S&P 500 closed at 7,489.72 on Friday 31 July, although the index still finished the month lower, its first losing July since 2014.
Who is suspected of hacking Minnesota’s water systems?
US intelligence agencies suspect Iran-linked hackers were behind a coordinated late-July attack on more than 30 municipal water systems across Minnesota. The incident quickly turned political: President Trump publicly blamed Governor Tim Walz and questioned whether Iran was involved at all, while Walz said federal cuts to cyber defences had left the country exposed.
When do the new 50% US tariffs on Canada take effect?
On 19 August 2026, under Section 338 of the 1930 Tariff Act, covering roughly US$20 billion of Canadian goods. Prime Minister Mark Carney and President Trump have agreed to intensify negotiations, leaving Ottawa only weeks to reach a deal, and doing so while about 800 wildfires burn nationwide and thousands in British Columbia are under evacuation orders.
