The Brazilian real weakened toward 5.5 per US dollar, nearing the early August low of 5.52 seen October 10th after a fresh repricing of trade risk raised immediate dollar demand. Reciprocal port fees and Chinese sanctions on US-linked units of South Korea’s Hanwha increased shipping frictions and the probability of sustained trade disruption, prompting importers, exporters and carriers to boost dollar hedges and cash buffers. Even strong Chinese commodity purchases, such as record September iron ore imports, do not eliminate the risk that seaborne flows will be delayed or rerouted, which reduces expected dollar receipts for exporters. Those external forces are compounded by domestic fiscal uncertainty after Congress shelved a tax overhaul that had been expected to improve the public finances, raising anticipated issuance and lowering foreign appetite for local currency assets.
