The USD/CAD pair is experiencing a tumultuous period, with the Loonie pair facing selling pressure as the US Dollar (USD) fluctuates due to potential diplomatic breakthroughs with Iran. The market's focus is on the possibility of a deal between the US and Iran, which could significantly impact the USD's value. This development, coupled with the Canadian markets' closure for Victoria Day, has led to a marginal drop in the USD/CAD pair to 1.3735 during the European trading session on Monday. The technical analysis reveals a complex landscape, with the 50% Fibonacci retracement near 1.3755 acting as a critical barrier. This level has proven to be a formidable resistance, preventing the pair from extending its advance. The Relative Strength Index (RSI) at around 56 suggests a modest bullish bias, but the momentum strength has yet to break through this retracement ceiling. On the upside, the 50% and 61.8% Fibonacci retracement levels at 1.3757 and 1.3807, respectively, present initial resistance. A sustained move above these levels could open the way toward 1.3877 and the cycle high area near 1.3966. Conversely, the 38.2% retracement at 1.3708 and the 20-day Exponential Moving Average (EMA) at 1.3696 provide support. A break below these levels could expose the 23.6% retracement at 1.3647 and more substantial structure around 1.3549. The market's sentiment is further complicated by the ongoing negotiations with Iran, which could significantly impact the USD's value and, consequently, the USD/CAD pair. As investors await the Canadian Consumer Price Index (CPI) data for April and the Federal Open Market Committee (FOMC) minutes of the April policy meeting, the Loonie pair's trajectory remains uncertain. The technical analysis, while providing insights, underscores the market's sensitivity to geopolitical developments and economic data releases. The USD/CAD pair's future trajectory will likely be shaped by the outcome of these negotiations and the release of key economic indicators, making it a crucial area of focus for traders and investors alike.
