Towards the end of the trading session, the US dollar showed signs of nervousness despite an initial rise influenced by higher-than-expected producer price index (PPI) figures for January and concerns over escalating tensions between the US and Iran. The PPI increased by 0.5% last month, surpassing analysts' expectations of a 0.3% increase, indicating a stronger-than-anticipated inflation scenario which is significant for monetary policy considerations in the US.

During intraday trading, the dollar index reached a low of 97.62 after starting at 97.79, while the euro recovered to 1.1818 from an initial 1.1797 against the dollar. Since February, the dollar has shown gains of approximately 0.6%, marking its first monthly rise since October of the previous year, while the euro recorded losses of 0.4%, reflecting its first monthly decline since October as well. This shift indicates potential adjustments in market expectations regarding currency performance amid economic indicators and geopolitical developments.

Against the Japanese yen, the dollar stabilized at 156.16, showing a rise of 0.9% in February against the yen. Meanwhile, the British pound declined by 0.20% against the dollar, reaching 1.3451, ending a quarterly rise. Such fluctuations in currency values underscore the ongoing global economic challenges and the impact of geopolitical uncertainties on national currencies, influencing both investor behavior and monetary policy planning moving forward.
