The British pound is lacking strength for any upside correction on Tuesday morning in Asia. The bulls are not active despite the weakness in the U.S. dollar. Consequently, the GBP/USD is struggling near the major psychological resistance level at 1.2300 level. Investors are looking for any fresh economic catalysts to take over this level. Meanwhile, the dollar index slipped a little in the red zone and showed a modest intraday loss. Momentum indicators are in the neutral zone but a break below the $1.2250 support zone could not be ruled out. The price is likely to post a steep fall once it breaks this support zone.
