The possibility of delayed US tax reforms weakening markets

Today most of the global markets have been weakened by news that the proposed tax reforms could be delayed, after a plan was unveiled to the Senate that is very different from that presented to the House of Representatives. In the Senate version, Republican members want to cut corporate tax in 2019, while the proposal in the House timetable was in 2018, which could complicate the biggest tax adjustment in the United States since the 1980s.
The news has weighed heavily on the US dollar as the dollar index began to recover somewhat during today's trading after falling yesterday to currently trading at levels of 94.36, but still recorded its worst weekly performance over the past four weeks.
The Reserve Bank of Australia announced its forecast this morning that inflation would reach below its target range by 2-3% by mid-2019, and previous forecasts had expected inflation to reach 2% by the end of 2018 before reaching 2.5% in 2019.
In line with these expectations, the Bank believes that inflationary pressures will take longer, so it may take time to tighten monetary policy and then raise interest rates.
