# US Dollar Hits 15-Month High Amid Inflation Concerns Rising US inflation triggers interest rate hike bets, weakening the Brazilian Real significantly. - **Source:** [Agência Brasil](https://agenciabrasil.ebc.com.br) - **Published:** 2026-11-10 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/7a101a02-84f2-4936-a042-af46dff71b68 ## Dollar Surge Reaches Peak The US dollar surged by 1.46% on Tuesday, reaching R$ 5.586. This marks the currency's highest closing value in over 15 months, specifically since July 31, 2025. The rapid appreciation follows a 5.20% increase in October and a further 2.60% gain during the first six trading sessions of November. ## Inflation Triggers Market Shift The primary catalyst for the dollar's rise was the US Consumer Price Index (CPI) data for October. Inflation rose by 0.4%, surpassing the anticipated 0.3%. The core indicator, excluding volatile food and energy prices, also climbed by 0.3%, signaling persistent inflationary pressures within the world's largest economy. ## Fed Rate Hike Expectations Following the CPI release, market expectations for Federal Reserve interest rate hikes intensified. The probability of a 0.25 percentage point increase in December rose to 88.2%, up from 84%. Furthermore, the chance of a more aggressive 0.50 percentage point hike emerged, reaching 11.8% after previously being estimated at zero. ## Ibovespa Follows Global Trend The Brazilian stock index, Ibovespa, closed down 0.52% at 171,336.99 points. This decline mirrored the negative sentiment across international markets, including Wall Street, where the S&P 500 fell by 0.38%. Investors remain cautious as higher US interest rates typically reduce the appeal of emerging market assets like Brazilian equities. ## Domestic Monetary Policy Pressures The minutes from Brazil's Copom meeting further weighed on local sentiment. The Central Bank highlighted rising inflation expectations and lowered economic growth projections. Officials attributed price pressures to supply shocks, including El Niño effects, labor costs, and the real's depreciation linked to ongoing uncertainties regarding domestic fiscal policy decisions. ## Oil Prices Decline Globally Oil futures experienced a second consecutive day of losses. Brent crude for January delivery fell 1.17% to US$ 91.49 per barrel, while WTI for December dropped 0.93% to US$ 86.04. The decline was driven by the stronger dollar and potential diplomatic easing of tensions between the United States and Iran. ## Geopolitical Impact on Commodities Market participants reacted to signals of potential diplomatic progress between Washington and Tehran. President Donald Trump indicated that the US is unlikely to escalate the conflict, which reduced risk premiums. Additionally, reports of recovering production in the Middle East and stabilized flows through the Strait of Hormuz pressured prices downward. ## Broader Economic Outlook Implications The current market environment reflects a global shift toward restrictive monetary policies. While the Ibovespa maintains a 6.34% gain for the year, the recent volatility highlights the sensitivity of emerging markets to US inflation data. Investors are now closely monitoring central bank communications to gauge the duration of high-interest rates. ## Sources covering this story - https://agenciabrasil.ebc.com.br/economia/noticia/2026-11/dolar-sobe-146-e-fecha-no-maior-valor-em-15-meses — --- _Summary written by Brifing from the original reporting.
