**Summary**: Talks to reduce US–Mexico tariffs on steel, aluminum and autos have reportedly stalled due to opposition from the US commerce secretary. The impasse preserves existing trade frictions, supporting a higher cost base for North American metals and autos and adding modest upside to US steel and aluminum prices.

## Detail

An intelligence report cites the Wall Street Journal in noting that negotiations between the United States and Mexico to reduce tariffs on steel, aluminum and automobiles have once again been blocked by US Commerce Secretary Howard Lutnick. While details on the scale and structure of the contested tariffs are limited in the brief, the key point for markets is that anticipated de‑escalation in North American trade frictions on these sectors is not materializing in the near term.

For metals markets, the failure to reach a deal sustains existing tariff barriers on Mexican steel and aluminum into the US market. That maintains a degree of segmentation in North American supply, supporting domestic US price premia for flat steel products and certain aluminum semis relative to global benchmarks. For autos, ongoing tariffs and uncertainty on cross‑border trade costs complicate OEMs’ supply chains and may encourage incremental reshoring or sourcing from alternative jurisdictions, which can be costlier in the short run.

The immediate effect is to remove a downside catalyst for US steel and aluminum prices that would have come from cheaper Mexican imports and more integrated supply. Instead, the status quo keeps a modest risk premium in place tied to policy unpredictability and potential further protectionist measures. Hot‑rolled coil and certain specialty steel products used in autos are most exposed. Aluminum markets, already sensitive to energy costs and Chinese export dynamics, may see incremental support for US Midwest premiums if Mexican inflows remain constrained.

Historically, tariff announcements and rollbacks in the steel/aluminum space (e.g., Section 232 actions, USMCA carve‑outs) have driven short‑term 2–5% moves in regional price benchmarks and equities of North American mills and fabricators. This episode is a negative surprise relative to expectations of gradual liberalization, so directionally it is mildly bullish for US‑domiciled producers and mildly bearish for Mexican exporters and integrated auto OEMs with heavy Mexico–US cross‑border flows. The impact is likely persistent as long as Lutnick’s opposition holds, with risk that the issue feeds into broader North American trade tensions ahead of US political milestones.
