Step 1:
Deficit financing refers to financing government expenditure through borrowing or printing new currency when expenditure exceeds revenue.
Step 2:
Deficit financing is mainly used for:
• Economic development
• Removing depression
• Poverty alleviation programmes
• Financing public sector activities
Step 3:
Deficit financing generally increases purchasing power and aggregate demand in the economy.
Hence, decreasing aggregate demand is not its objective.
Step 4:
Therefore, the option which is not an objective of deficit financing is:

\boxed{\text{To decrease aggregate demand}}
\]
Hence, the correct answer is:
\[
\boxed{\text{(2) To decrease aggregate demand}}
\]
