Fiscal Strategy Model

Page updated 15 Dec 2009

The Fiscal Strategy Model (FSM) projects the financial performance and the financial position of the government over a medium-term horizon and is published once a year with the Budget.

Note: Previously these medium-term projections were done by the Long Term Fiscal Model (LTFM) however the LTFM is now used solely for longer-term projections (minimum of 40 years).

Fiscal Strategy Model Projections

The principal purpose of the FSM is to produce the post-forecast fiscal projections. The Half Year Economic and Fiscal Update 2009 updated version of the FSM is published here on the Treasury's website.

The projections:

• begin from the end of the five-year forecasts in Economic and Fiscal Updates (EFUs) and cover a period of at least five further consecutive years;
• are strongly influenced by the EFU forecasts;
• are consistent with Government’s approach to fiscal management in that new initiatives are modelled through an assumed operating and capital allowance;
• rely on long-term assumptions such as future population growth and economic growth;
• include some degree of recovery to these long-term assumptions in the early years of the projections, if the long-term rates or levels have not been reached at the end of the forecast period; and
• are required to be published annually, as part of the Fiscal Strategy Report, under the Public Finance Act (1989).

Notes for this Version of the Fiscal Strategy Model

• Scenarios for different levels of operating expenses and revenue can be tested using the Ready Reckoner sheet of the FSM. The output of the Ready Reckoner is in the Option worksheet.
• The FSM has been updated to incorporate the latest economic and fiscal forecasts contained in the HYEFU. Assumptions underpinning the HYEFU FSM are outlined in detail in Projection assumptions of the Half Year Economic and Fiscal Update 2009 (15 December 2009).

Differences between the Fiscal Strategy Model and the Long-Term Fiscal Model

Treasury produces a second model of projections of fiscal variables in the Long-Term Fiscal Model (LTFM).

The LTFM differs from the FSM in that modelling for the LTFM is for a minimum of 40 years and is not intended to assess the Government's fiscal strategy. In particular, the use of an operating and capital allowance ('Top Down' approach) to model new initiatives in the medium term (FSM) allows assessment of the Government’s stated intentions for future policy against its long-term objectives. In contrast, the LTFM grows individual expenditure classes based on 'Bottom Up' cost drivers, such as changes in population and assumed expense growth factors.
