QE & Reserve Requirements - Quick Reference

Quantitative Easing (QE) Overview

• QE: central bank asset purchases to inject liquidity and support spending/credit growth.
• Data signal: QE should show up in macro data as spending and credit expand.
• Asset mix in QE: transcript discusses buying securities; question arises about including non-Treasury assets (e.g., MBS); the excerpt indicates focus on Treasuries with some ambiguity about other assets.

Asset Purchases in QE

• Common focus: U.S. Treasuries as the primary purchases.
• Transcript note: question about whether non-Treasury securities (like mortgage-backed securities) are included; the exact answer in the excerpt is unclear.

Reserve Requirements

• Definition: Reserve requirements are the minimum amount banks must deposit at the Federal Reserve.
• Notation: R = r \cdot D where r is the reserve ratio and D is deposits.
• Example: Decreasing reserve ratio from 0.10 to 0.05: r: 0.10 \rightarrow 0.05.
• Effect: Lowering the reserve ratio reduces the amount of reserves banks are required to hold.

Bank Reserves

• When the reserve ratio falls, banks are holding fewer reserves at the Federal Reserve.
• This reflects that the deposits kept at the Fed decrease as the required reserve portion shrinks.

Quick Clarifications from Transcript

• Reserve requirements refer to the minimum deposits banks must place with the Federal Reserve.
• The discussion includes how changing the reserve ratio affects how much banks must hold in reserve at the Fed; lowering the ratio means fewer required reserves.
