Chile's peso led losses across Latin American currencies on Thursday as the central bank indicated that monetary policy would remain loose for longer, while most other units came off a series of strong sessions.

The peso dropped 1.2% as the central bank projected monetary policy to remain below neutral levels for the next two years. This came after the bank hiked rates to 0.75%, citing a pickup in local economic growth and inflation.

Still, the dovish outlook means Chilean lending rates will largely lag their emerging market peers. Brazil and Mexico, for instance, have hiked rates to 4.25% each this year, as economic growth and inflation heats up.

While Chile's interest rates sinking to 0.5% have been a symptom of the COVID-19 pandemic, the bank had been steadily cutting rates since mid- to late-2019 as a series of violent anti-government protests disrupted economic activity.

Focus is now on the drafting process of a new Chilean constitution, which investors fear could introduce radical changes to market policy.

"We see very limited value in the monetary policy committee's dovish unconditional medium-term guidance, particularly in the context of fiscal policy in hyper-drive," Goldman Sachs analysts wrote in a note.

"A significant improvement in the COVID backdrop, above target headline and core inflation and supportive external backdrop have reduced to a very significant extent the need for monetary policy to continue to support the recovery."

Goldman Sachs sees Chilean rates between 1.5% to 1.75% by end-2021, while Credit Suisse sees them at 1.5%.
