Fiscal Injection, Monetary Impulse | EI Blog

FIMI does not predict what a government will do. It classifies what it has done, and directs the analyst toward the correct transmission mechanism, the correct positioning horizon, and the correct risk assessment.

The South Korean case was not a crisis. It was a clean, verifiable example of a mechanism that is becoming more common as governments in post-QE environments seek tools that produce monetary-scale demand effects without requiring central bank action. The same logic applied in three jurisdictions over six years. The probability of recurrence is non-zero, and the precedents make it not a hypothesis.

When the next case emerges practitioners who have a name for it and a checklist to verify it will be positioned ahead of those who reach for the nearest available label.

The label determines the position. The wrong label means the wrong trade.
