The watchdog was asked by Liberal MP John McKay to analyze the impact of lower oil prices on projected federal surpluses through 2019-20.
The projections work through the numbers for two scenarios:- West Texas Intermediate (WTI) stays at its recent price of $48 a barrel through the entire time period.
- WTI sits at an average of $51 for 2015 and then rises gradually to $81 in 2019.
In the rosier scenario, the analysis suggests the books can show a small surplus of $700 million, assuming the contingency fund is tapped.
"The path for oil prices over the next five years is uncertain," the report from Jean-Denis Frechette's office cautions.
If something resembling the first scenario comes to pass, the PBO estimates that a price of $48/barrel would would reduce federal budgetary revenues by approximately $7.6 billion annually, on average, over 2015‐16 to 2019‐20.
Overall, the federal budgetary balance would be reduced by $4.8 billion annually, on average, over 2015‐16 to 2019‐20.
Estimates don't factor in declining GDP
The impact across Canada's economy would result in lower household incomes and corporate profits, the report says, which would reduce the federal government's personal and corporate income tax revenues.
But lower prices also reduce the government's expenses when it purchases goods and services, partially offsetting the lost revenue.
Spending on programs that are indexed to inflation — elderly benefit payments and the Canada child tax benefit, for example — would be lower. Spending that's tied directly to growth in nominal GDP, like transfers to other levels of government, would also be lower.
The PBO stresses, however, that the impacts of lower oil prices considered in its two scenarios do not include impacts from Canada's lower real GDP that would likely materialize.
"As such, the fiscal impacts [in absolute terms] should be viewed as lower bound estimates," the report concludes.
Last week, the Bank of Canada scaled back its forecast for GDP growth, attributing low oil prices in its decision to cut the key overnight lending rate by a quarter of a percentage point.Suggest a correction
