Ay Mamá, Las Nuevas Bancadas: A Chronicle by Fernando Vivas on Peru’s New Congress

Peru’s newly elected Congress is facing a pivotal moment as it prepares to implement a bicameral system, a reform that will double the size of legislative factions and reshape the balance of power between established parties and emerging forces. According to political analyst Fernando Vivas writing in El Comercio, the transition to a two-chamber legislature will transform existing congressional bancadas into expanded, dual entities, with some groups growing to as many as six members while others remain small, consisting of only three senators or more.

Vivas describes the current vote-counting process as unfolding “gota a gota” — drop by drop — as officials finalize the exact number of seats each party will hold in the new Congress. This careful tally is critical because the bicameral structure, approved in recent constitutional reforms, will not simply replicate the current unicameral model but will instead create two separate chambers: a Senate and a Chamber of Deputies. Each party’s representation will be split across both, effectively doubling the number of legislative groups and altering internal dynamics.

The analyst warns that while the reform promises greater deliberation and reflection — what he calls “bicameralidad reflexiva” — it also carries risks of renewed political pacts that could undermine accountability. He references the threat of a new “‘pacto mafioso’ con iniciativa de gasto,” suggesting that alliances formed behind closed doors might once again prioritize mutual benefit over public interest, particularly in budgetary decisions. This echoes concerns from past periods when informal agreements between parties led to opaque spending and weakened oversight.

To understand the implications, Vivas urges readers to examine both the veteran legislators returning to office and the newcomers entering Congress for the first time. The interplay between these two groups, he argues, will determine whether the bicameral system strengthens democratic deliberation or becomes another vehicle for entrenched interests. The experience and institutional memory of returning members could provide stability, while the influx of new representatives may bring fresh perspectives — or be absorbed into existing power structures.

The shift to bicameralism marks a significant departure from Peru’s recent legislative framework, which had operated under a single congress since the 1993 constitution. Proponents of the reform argue that two chambers will improve checks and balances, enhance regional representation through the Senate, and slow down hasty legislation. Critics, however, caution that without strong ethical safeguards and transparency measures, the expanded legislature could increase opportunities for patronage and gridlock.

As the final seat allocations are confirmed, the formation of the new bancadas will be closely watched by political analysts and citizens alike. The success of the bicameral system will depend not only on its design but on how parties adapt to the dual-chamber reality, whether they prioritize cooperation or confrontation, and whether the promised deliberative gains materialize in practice. For now, the country waits as the final votes are tallied and the contours of Peru’s next Congress take shape.
