# Mexican peso volatility and depreciation trends > Live situation record from CLSTR: https://clstr.news/situations/global-market-volatility-and-inflation-trends > Updated: 2026-10-20T21:41:54.000Z. Sources: 49. Developments: 5. Global financial markets continue to experience intensified volatility driven by rising US Treasury yields, surging oil prices, and Middle East geopolitical tensions. The US ten-year Treasury yield has climbed above 5.2%, while Brent crude prices have risen above 100 USD per barrel following US President Donald Trump’s rejection of an Iranian proposal regarding the Strait of Hormuz. This environment of risk aversion has significantly impacted emerging market currencies, specifically the Mexican peso. The currency has reached a near one-year low, closing at approximately 18.41 pesos per US dollar after five consecutive weeks of losses. This represents a 9 percent decline since its yearly low in early September. The depreciation is increasingly driven by shifting monetary policy expectations. Recent minutes from the Banco de México (Banxico) monetary policy meeting revealed that three out of five Governing Board members are open to considering further cuts to the benchmark interest rate, depending on inflationary conditions. Investors are concerned that these potential cuts in Mexico, contrasted with a more cautious stance from the US Federal Reserve, will further narrow the interest rate differential. This trend reduces the attractiveness of the peso for ‘carry trade’ operations, with speculative positions betting on peso appreciation reportedly plummeting by nearly 80 percent during the first week of October. As of mid-October, the peso has entered a six-week losing streak, reaching a low of 18.6060 pesos per dollar—its weakest level since November 2025. Beyond interest rate differentials, depreciation is being fueled by geopolitical instability following reports of an explosion involving a tanker in the Strait of Hormuz, uncertainty surrounding the upcoming US elections, and the ongoing review of the US-Mexico-Canada Agreement (USMCA). Recently, the peso has shown signs of recovery, breaking its six-week losing streak. ## Claims - The Mexican peso closed at 18.41 units per dollar on Friday.
