The Brazilian real fell about 0.6pc following a global surge in risk assets on Monday after the United States and China agreed to get back to negotiating their long-drawn trade dispute, which has roiled for financial markets.

In Brazil, investors are awaiting lawmaker Samuel Moreira's presentation of proposed changes to the government's pension reform bill in a congressional committee later in the day.

The Colombian, the Chilean and the Argentine pesos all dipped slightly.
