The Superintendencia del Mercado de Valores updates the Single Account Plan (PUC) and DS-01 report to include new subaccounts and a dedicated sheet for transactions with the Social Security Fund (CSS) and SIACAP. These changes mandate that securities houses report balances and transaction details for these specific government institutions starting with the July 2026 reporting period, with a submission deadline of August 17, 2026. The updated CSV templates are available on the regulator's website under the SERI Forms section.
