Monetary policy is often feared to have limited traction in emerging markets. Yet, empirical evidence supporting or disproving these concerns is scarce. This column constructs novel monetary policy shocks based on analysts’ forecasts of policy rate decisions. Critical for the identification of the shocks, analysts can update their forecasts up to the time of the monetary policy meeting to incorporate any information deemed relevant to the interest rate decision. Using these shocks, the authors find that monetary policy in emerging markets wields considerable influence on financial and macroeconomic conditions, with a particularly pronounced impact on leveraged firms.
Proverbial concerns remain about the traction of monetary policy in emerging markets due, for example, to lower financial development and weaker institutional credibility (Frankel 2010). These concerns have been amplified by highly influential studies showing that powerful global financial forces – largely driven by US monetary policy – strongly affect financial conditions in emerging markets, even those with flexible exchange rates (Rey 2013, Bruno and Shin 2015, Kalemli-Özcan 2019, Miranda-Agrippino and Rey 2020). More recently, De Leo et al. (2023) have documented that a US monetary tightening raises borrowing and lending rates in emerging markets even though local central banks react by cutting policy rates.
This evidence has been at times interpreted as indicating severe impairments in the transmission of monetary policy in emerging markets. As discussed in Rey (2013), the strength of the global financial cycle might even transform Mundell’s Trilemma into a Dilemma, where countries can only maintain monetary policy independence by regulating capital flows or adopting stringent macroprudential frameworks. However, as discussed in Obstfeld (2015) and Gourinchas (2018), the fact that emerging markets’ financial conditions are sensitive to global financial shocks does not necessarily imply that monetary policy in emerging markets can no longer influence domestic macroeconomic and financial conditions. Global financial shocks clearly pose challenges – possibly even trade-offs – for emerging markets’ central banks. But domestic monetary policy may still retain traction in steering economic conditions.
An accurate assessment of monetary policy transmission in emerging markets requires carefully identifying domestic monetary policy shocks. This task has proven to be particularly challenging. For example, high-frequency identification techniques that have been successfully used in advanced economies (Kuttner 2001) are problematic in the context of emerging markets because of limited market liquidity.
New monetary policy shocks for emerging markets
To overcome these challenges, in a recent paper (Checo et al. 2024) we construct a new set of monetary policy shocks for 18 emerging markets, going back in some cases to the early 2000s, using analysts’ forecasts of policy rate decisions. The identification assumption is that analysts construct their forecasts by factoring in the endogenous reaction of monetary policy to economic conditions. Hence, forecast errors can be leveraged to isolate the variation in monetary policy decisions unrelated to economic developments. Critical for identification, we use survey data collected by Bloomberg which allows analysts to update their forecasts up to the time of the monetary policy meeting to incorporate any data releases that could influence the policy rate decision. We indeed find evidence that analysts tend to provide accurate forecasts by finalising their submissions closer to the policy meeting when the policy rate decision is more uncertain.
To further ensure that forecast errors are free from any endogenous variation in monetary policy linked to macroeconomic developments, we orthogonalise them with respect to a broad range of macroeconomic and financial variables available before each policy meeting, as in Bauer and Swanson (2023b). We detect limited predictability of the forecast errors, consistent with the notion that analysts already incorporate the endogenous response of monetary policy to economic conditions.
Monetary policy transmission to financial markets
We start by examining the effects of monetary policy shocks on financial markets in the days following monetary policy decisions. We find that monetary policy has pronounced and persistent effects on sovereign bond yields (Figure 1, Panel A). A one percentage point monetary policy shock raises one-, two-, and five-year bond yields by about 100, 80, and 50 basis points, respectively. Monetary policy also tends to compress bond spreads, appreciate the exchange rate, and reduce stock prices, but these effects are short-lived, dissipating within a few days after the policy announcement (Figure 1, Panel B).

Notes: The figure shows the effects of a one percentage point monetary policy shock on financial variables during the 30 days following the shock. The shaded areas correspond to 90% confidence intervals constructed with robust standard errors.
Monetary policy transmission to macroeconomic conditions
We then assess the transmission of monetary policy to macroeconomic conditions (Figure 2). In line with theoretical predictions, a monetary policy tightening depresses economic activity. Industrial production declines rapidly (Panel A), reaching a trough after about three quarters. The unemployment rate increases more gradually but also more persistently (Panel B). Tightening monetary policy also reduces inflationary pressures. The impact is relatively rapid on producer prices (Panel C) while consumer prices decline after a longer lag (Panel D). We also find evidence that the exchange rate tends to appreciate in response to a monetary policy tightening. The transmission lags and the quantitative effects of monetary policy on macroeconomic conditions are broadly in line with the evidence from the US presented in Bauer and Swanson (2023a).

Notes: The figure shows the effects of a one percentage point monetary policy shock on macroeconomic variables during the 36 months following the shock. The shaded areas correspond to 90% confidence intervals constructed with standard errors clustered at the country level.
Monetary policy transmission across firms
Lastly, we also examine the transmission of monetary policy using firm-level data. This makes it possible to explore the heterogeneity in the impact of monetary policy shocks depending on firms’ financial conditions. Echoing the evidence from advanced economies (Caglio et al. 2022), we find that a monetary policy has stronger effects on investment decisions by highly leveraged firms. We also find suggestive evidence of stronger investment responses among firms with lower liquidity or that do not pay dividends. These results confirm the importance of financial frictions in influencing the transmission of monetary policy, even in emerging markets.
Figure 3 Heterogeneous responses of investment across firms
Notes: The figure shows the effects of a one percentage point monetary policy shock on firm-level variables during the 12 quarters following the shock, differentiating across firms’ financial characteristics. Panel (a) compares firms with the leverage ratio equal to the 10th and 90th percentiles of the sample distribution and panel (c) compares firms that paid dividends in their past to firms that never did. The shaded areas correspond to 90% confidence intervals constructed with standard errors clustered at the firm and time level.
Encouraging evidence about monetary transmission in emerging markets
In summary, the analysis provides encouraging evidence about the strength of monetary policy transmission in emerging markets. Using our newly constructed monetary policy shocks, we show that monetary policy influences financial markets, macroeconomic conditions, and firm-level decisions in line with theoretical predictions. Monetary policy in emerging markets may thus be better positioned to control domestic economic conditions and lean against global financial shocks than commonly assumed. The surprising resilience of emerging markets during the post-pandemic global monetary tightening offers an additional indication of such a success, which is likely underpinned by improvements in macroprudential (Sandri et al. 2020) and monetary policy frameworks (Kalemli-Özcan and Unsal 2019).
