The Reserve Bank will cut the cash rate to a record low of 0.25 per cent and target four-year government bonds in the country’s first major quantitative easing package worth a speculated $50 billion, all designed to contain a blowout in borrowing costs for corporates and the federal government
…The three-year bond rate has increased from a low of 0.37 per cent in early March as market panic set in, to 0.5 per cent, having traded at 0.75 per cent in mid-February. While the five-year bond rate has also risen 40 per cent since March, from 0.45 per cent to 0.65 per cent, having traded at 0.8 per cent in mid-February.
