FxWirePro: Are Banxico Rate Cuts On Cards? Uphold USD/MXN Debit Call Spreads

The Mexican central bank’s (Banxico) meeting minutes give the impression that massive rate cuts in support of the economy are rather unlikely. Even though the central bank cut its key rate by 50bp to 6.5% on 20th March, one week ahead of the regular meeting, one of the five members voted in favour of a smaller 25bp cut. And the minutes sound clearly cautious. On the one hand the central bank sees a high upside and also downside risk for inflation. After all what is going to be more pronounced? The supply side or the demand shock? And to what extent will the weak peso push inflation upwards? Can the significant fall of the oil price and other commodity prices (over) compensate for this development? And in the end of course the realisation that it is really up to the Ministry of Health and that of Finance to control the pandemic and cushion economic effects. The high Mexican key rate was so far unable to prevent the peso from depreciating significantly. Uncertainty is too high for that. From a longer term perspective, once the situation has calmed down again and investors begin investing in EM asset once again, it might help the peso that interest rates in Mexico are comparatively high (we only expect moderate rate cuts this year to 5.75%). Until then investors are more likely to be driven by concerns that both monetary and fiscal policy have reacted only moderately to the deterioration of the economic situation. The peso should therefore continue to struggle.
