In a remarkable turn of events, the dollar soared to multi-week highs against both the euro and yen on Monday, buoyed by promising data indicating a rebound in U.S. business activity for March. This surge followed reports of President Biden's potential flexibility regarding upcoming tariffs, igniting investor confidence.

The cryptocurrency realm also celebrated, with Bitcoin rising to a staggering $88,772—the highest it has been since March 7—driven by an overall increase in risk appetite among traders.

Key metrics from S&P Global reveal that the flash U.S. Composite PMI Output Index—a critical gauge of both manufacturing and services—jumped significantly from 51.6 in February to 53.5 this month. Any reading above 50 signifies expansion, showcasing a resurgence in the private sector. Interestingly, the services sector played a pivotal role in this upswing, likely influenced by escalating temperatures as spring approaches. In contrast, manufacturing slipped back into contraction for the first time in three months.

Adam Button, chief currency analyst at ForexLive in Toronto, emphasized the importance of the services sector's performance, stating, "The services side is a much larger component of the U.S. economy, making this news quite positive."

The dollar's ascent against the yen was further propelled by reports from credible sources such as Bloomberg and the Wall Street Journal, suggesting that the Biden administration intends to omit certain sector-specific tariffs while implementing reciprocal levies by April 2. "The initial shock regarding tariffs has evolved into a more measured market perspective," noted Button.

At its peak, the dollar increased by 0.7% against the yen, hitting 150.35, reaching heights not seen since March 3. As Karl Schamotta, chief market strategist at Corpay, put it, "There's a wave of cautious optimism sweeping the foreign exchange markets, stemming from hopes that next week's tariff announcements will be less severe than initially anticipated."

However, traders remain wary, avoiding large directional bets as the tariff discussions could provoke retaliatory responses from major trade partners, potentially destabilizing both U.S. and global economies and further elevating volatility in currency markets.

Throughout the year, the dollar has faced headwinds as investors' initial hopes for prompt pro-growth policies from Biden transitioned to concerns over the implications of ongoing trade restrictions. Recently, Biden announced intentions to impose a 25% tariff on automobiles while also targeting semiconductors and pharmaceutical imports. Nevertheless, lobbying efforts from major U.S. automakers seeking exemptions led the administration to postpone certain auto tariffs.

Meanwhile, the euro eased slightly by 0.09% to $1.0804, experiencing its lowest value since early March at $1.079. The Eurozone displayed promising growth in business activities, witnessing its fastest pace in seven months, despite a deceleration in service sector expansion.

In the UK, sterling made a slight gain, climbing 0.09% to $1.2926 ahead of a significant budget update scheduled from British finance minister Rachel Reeves later in the week.

Further complicating the global economic landscape, the Turkish lira experienced minor weakening following the jailing of Istanbul Mayor Ekrem Imamoglu, a key opponent of President Tayyip Erdogan, on graft charges—a claim Imamoglu staunchly denies. The lira briefly plummeted to a record low last week amid tight monetary policy decisions.

As markets remain highly attuned to potential geopolitical developments, attention now turns to the ongoing discussions for a ceasefire in the Black Sea, as U.S. and Russian officials convene in Saudi Arabia.
