Trump’s Trade War Hits Brazil, But Treasury Yields Stay Calm

U.S. Treasury yields barely budged Thursday, even as President Trump escalated his trade offensive with two major moves: 50% tariffs on copper imports and fresh levies on Brazil. The bond market’s muted reaction suggests that investors are still digesting the long-term impact of the White House’s intensifying trade war.

As of early morning trading:
-The 10-year yield hovered around 4.35%
-The 30-year yield nudged up to 4.88%
-The 2-year yield edged slightly down to 3.86%

Despite the escalating rhetoric, Treasury markets remained largely steady—a sign of cautious optimism or perhaps disbelief that the tariffs will fully stick.

Brazil in the Crosshairs
Late Wednesday, Trump slapped 50% tariffs on Brazilian imports, escalating a standoff sparked by the prosecution of former Brazilian President Jair Bolsonaro. The move also builds on earlier 10% tariffs imposed in April, which the White House now says weren’t enough to correct what it calls a “very unfair trade relationship”.

Brazil responded swiftly. President Luiz Inácio Lula da Silva vowed reciprocal action, citing Brazilian law that authorizes countermeasures against foreign trade restrictions.

Copper Tariffs Begin August 1
Alongside the Brazil move, Trump confirmed that copper imports will face a 50% tariff starting August 1, a decision reportedly driven by national security assessments. Copper is considered vital for defense, tech infrastructure, and clean energy—making it a strategic target for reshoring efforts.

Traders have already pushed copper prices higher in anticipation, with commodity markets bracing for supply constraints and cost shocks across sectors from construction to semiconductors.

Eyes on the Data
While geopolitics heats up, investors are also watching domestic signals. Weekly jobless claims for the period ending July 5 were set to be released later in the day, and the Fed’s stance on interest rates remains cautious.


​Bottom line: Trump’s trade war is back in full swing, now with Brazil and copper in the crosshairs. But Treasury yields are holding their ground—for now. Whether this calm lasts depends on whether the tariffs stick and how hard retaliation hits. Markets are watching—and waiting.
