FXStreet (Guatemala) - Valeria Bednarik, chief analyst at FXStreet explained that the dollar edged higher this Tuesday, benefited by an improving risk sentiment and a slid in oil prices to fresh multi-year lows, with US sweet, light crude reaching $30.00 a barrel. Key Quotes: "The common currency, however, is still refusing to give up against the greenback, given that the EUR/USD pair bounced from a daily low of 1.0819, holding within its recent range. But both, the Pound and the Canadian dollar plummeted to fresh multi-year lows, the first on the back of poor local data and the second following oil's prices. In the US, consumer confidence edged up in January, as the IBD/TIPP Economic Optimism Index posted a reading of 47.3 vs. 47.2 in December. The NFIB business optimism index also edged higher, reaching 95.2 in December from a previous 94.8, although missing expectations of 95.4." For more information, read our latest forex news.
