Ultimately, the central bank's decision to stop purchasing government debt likely stems from its mandates around economic stability and price levels. However, by stopping debt monetization, the central bank allows suppressed market forces to re-emerge, bursting asset bubbles inflated by artificial credit. This unavoidable recession purges prior monetary distortions.
The central bank then faces a choice: accept the painful but necessary recession to restructure resources toward sustainable uses, or risk reigniting the boom-bust cycle by resuming easy money policies, delaying the reckoning but inevitably fueling higher inflation. The choice is either short-term pain to cleanse imbalances, or perpetuating distortions until they manifest as a graver predicament.
