NextFin News - The Chilean Senate began formal deliberations Wednesday on a sweeping economic reform package proposed by President José Antonio Kast, a legislative "mega-bill" that has become the centerpiece of his administration’s effort to dismantle decades of fiscal policy in favor of a free-market overhaul. The bill, which cleared the lower house in late May, arrives in the upper chamber as economists and opposition lawmakers intensify warnings that the proposed tax cuts and deregulation could destabilize the nation’s fiscal balance and widen social inequality.
The legislation includes the elimination of capital gains taxes on low-value stock sales, the creation of broad employment subsidies, and a significant reduction in corporate tax rates. President Kast, who took office in March 2026 following a campaign that mirrored the populist, law-and-order rhetoric of U.S. President Trump, has framed the bill as a "shock therapy" necessary to revive an economy that has struggled with stagnant productivity. However, the Senate’s Finance Committee has already signaled that the bill faces a much steeper climb than it did in the Chamber of Deputies, where a more fragmented opposition allowed for a swifter passage.
Carolina Gonzalez, a senior analyst at Santiago-based consultancy Andes Macro, noted that while the bill aims to stimulate investment, the fiscal cost remains "dangerously opaque." Gonzalez, who has historically maintained a cautious, data-driven stance on Chilean fiscal policy and often critiques rapid shifts in tax structures, argued that the administration has yet to provide a credible plan to offset the projected revenue losses. Her assessment, which reflects a growing skepticism among local institutional researchers, suggests that the bill’s current form may lead to a credit rating downgrade if the fiscal deficit widens beyond the 2.5% target set by the previous administration.
The debate in Valparaíso is unfolding against a backdrop of civil unrest. As the Senate convened, protesters clashed with police outside the National Congress, echoing the volatility that has defined Chilean politics since the 2019 social uprising. Critics of the bill argue that the employment subsidies are skewed toward large corporations and do little to address the rising cost of living for the middle class. Conversely, supporters within the Kast administration contend that the "trickle-down" effects of the tax cuts will eventually bolster the treasury through increased economic activity and foreign direct investment.
The Senate is expected to demand significant amendments, particularly regarding the "sunset clauses" for the proposed subsidies and the specific thresholds for capital gains exemptions. While the administration holds a narrow majority in the lower house, the Senate remains more balanced, with centrist blocs holding the power to stall or significantly dilute the "mega-bill." The outcome of these negotiations will likely determine the trajectory of the Chilean peso, which has seen increased volatility as investors weigh the promise of deregulation against the risk of renewed social instability.
