Why the Mexican peso surged against the USD?

On Wednesday, the US dollar decreased in value against other major currencies, including the Mexican peso, by over 1%, due to reports of slower than expected US inflation. This suggests that the Federal Reserve may pause its interest rate hikes. According to data from the US Labor Department, inflation in April decreased to 4.9%, which is the lowest year-over-year increase in two years and lower than market forecasts of 5%. The slower inflation was attributed to slower growth in food prices and a further decrease in energy costs.

However, core inflation remained high at 5.5%, indicating that interest rates may need to stay high for some time to control it. Fed funds futures traders are anticipating a pause before expected rate cuts in September, which might be a little optimistic, as the Fed's target range remains at 5% to 5.25%.

The Mexican peso gained strength to 17.544, its highest value since July 2017, as the difference between US and Mexican monetary policies became more pronounced. The RSI on the USDMXN suggests it is in an extreme oversold condition, so a pullback may be necessary. Resistance levels from 2017 for the pair may no longer be relevant, but the strongest value the peso reached in 2017 was $17.430, while the peak in 2016 was $17.050.

For fundamental context, Banxico increased rates to an all-time high of 11.25% in March, despite a decrease in annual headline inflation that was greater than expected. Mexico's proximity to the US has also made it an attractive location for foreign companies to open factories targeting the American market and diversifying production from China. Additionally, the US economy's robust state has led to a rise in remittances to Mexico from expats.
