In response to the surge in inflation that adopted the pandemic recession of 2020, Latin America’s central banks responded way more aggressively than authorities in different areas, as could also be seen in Determine 1 beneath.
Determine 1: Adjustments in Coverage Curiosity Charges Since December 2020
The relative hawkishness of Latin American central banks was additionally evident conditional on the rise of inflation, as proven in Determine 2. The horizontal axis exhibits how a lot core (excluding meals and vitality) inflation has elevated in every nation since December 2020, simply earlier than inflation began selecting up worldwide. The vertical axis measures every nation’s enhance in coverage rates of interest over that interval. Clearly, as indicated by the blue regression line, international locations experiencing bigger will increase in inflation have boosted coverage rates of interest by extra. The central banks of Latin America lie near or above the shaded area (representing a 68% confidence interval).
Determine 2: Will increase in core inflation and coverage charges from December 2020 to August 2023
My colleagues Rafael Guerra, John Kearns, Christian Higher, Aatman Vakil, and I wished to know whether or not Latin American central banks have at all times been very aggressive of their response to inflation, or whether or not they had grow to be extra hawkish in recent times. We began by estimating a panel Taylor Rule regression for coverage charges of the 5 principal inflation-targeting central banks—Brazil, Chile, Colombia, Mexico, and Peru—through the pre-pandemic interval. Column 1 (which features a actual alternate charge—not important) and column 2 (which doesn’t) present that within the pre-pandemic interval, each inflation and the output hole influenced coverage charges, and with reasonably-sized coefficients. However column 3, which extends the estimation by 2023 and contains dummy variables for the post-2019 interval, exhibits that the coefficient on inflation rose considerably and the coefficient on the lagged coverage charge fell, indicating much less interest-rate-smoothing.
Furthermore, as proven in Determine 3 beneath, projections of the pre-pandemic estimated Taylor Rule into the pandemic interval confirmed that many of the Latin American central banks tightened coverage way more sharply (the purple line) than predicted by the pre-pandemic mannequin (the blue line). This implies, once more, that Latin American central banks had grow to be way more hawkish towards inflation after 2019.

Nonetheless, we weren’t satisfied that the Latin American central banks’ response capabilities had really modified. As an alternative, we conjectured that Latin American financial coverage might have exhibited a non-linear response to inflation, with the sensitivity of rates of interest rising as inflation turns into particularly pronounced. Such conduct might replicate issues that the upper inflation rises, the higher the chance that inflation expectations grow to be unanchored, and subsequently the higher the necessity to reverse the rise in inflation.
So we re-estimated the Taylor rule mannequin described above, however including interplay phrases with inflation, as proven in Desk 2. The coefficient on the extent of inflation is now insignificant, whereas the coefficient on its sq. is optimistic and considerably completely different from zero. This configuration signifies that through the pre-pandemic interval, the sensitivity of rates of interest to inflation grew bigger as inflation itself rose. In different phrases, rates of interest exhibited a non-linear response to inflation.
In column 3, we lengthen the estimation by 2023 and embrace the interplay phrases with the pandemic dummy. The coefficients on each the output hole and the sq. of inflation are unchanged through the 2021–23 interval from their values within the pre-pandemic interval. This implies that this non-linear model of the mannequin might higher seize the conduct of financial coverage over each pre- and post-pandemic intervals. Notably, the non-linear mannequin nonetheless exhibits a big decline within the coefficient on the lagged coverage charge from the pre-pandemic interval; that is value exploring in additional analysis.
We now return to Determine 3 above. The inexperienced traces in Determine 3 evaluate the out-of-sample predictions of the non-linear mannequin to the precise paths of rates of interest (in purple) and the predictions of the linear Taylor rule fashions (in blue) described above. As could also be seen, the non-linear fashions come a lot nearer to monitoring the sharp rise in rates of interest throughout 2022 and 2023 in Brazil, Chile, and Colombia.
Subsequently, the aggressive response of financial coverage to inflation in 2021–2023 seems to have been much less of a break from earlier conduct than it’d seem from the attitude of a linear Taylor rule. That aggressive response was in keeping with earlier responses of Latin American central banks to sharp surges in inflation. Our outcomes are sturdy to completely different definitions of costs and output and completely different econometric specs. We intend in future analysis to see if this conclusion holds for financial coverage in different components of the world.
