Extract: Government spending has increased substantially in recent years. Consequently, the breakeven oil price rose to $106 a barrel in 2014 from $69 a barrel in 2010. As a result, with the large decline in oil prices, the fiscal deficit has increased sharply and is likely to remain high over the medium-term.
Over the 2004-15 sample period, the correlation between the daily changes in breakeven inflation and West Texas Intermediate (WTI) spot oil prices is positive and substantial, ranging from 0.34 to 0.41, depending on the forecast horizon of breakeven inflation.
