The Essence of Finance
At its very basics, the financial system:
- Consists of financial intermediaries between borrowers and lenders
- Moves claims around the world over people, time, space, and uncertain states of nature.
- Turns illiquid assets into liquid assets…- but the mismatch of assets and liabilities causes the
fundamental instability of the financial system.

How the Fed influences financial markets
• Begin with short-run interest rate (federal funds rate)
• Supply of money and reserves determined by central bank (Fed, ECB, …)
• Demand for transactions money (M1) from medium of exchange;
• Equilibrium of supply and demand for money/reserves → short-term nominal risk-free interest rate.
• Then to other assets and rates:
• Short risk-free rate + expectations → long risk-free rates• Risky rates = risk-free rate + risk premiums• Real rate = nominal rate – inflation (Fisher effect)
![Page 10: 1 Money, Finance,and the Crisis of 2008-2012. Outline of money section 1.Essence of financial markets 2.Balance sheets 3.Introduction to the supply and.](https://reader030.fdocuments.in/reader030/viewer/2022020117/56649daa5503460f94a97959/html5/thumbnails/10.jpg)
Central thing to understand is how the Fed (and other central banks) determines short run, nominal interest rates.
They do this by determining the level of bank reserves; then short rates are determined by supply and demand in the bank-reserve market.
We emphasize policy in normal times. Today is not a normal times because in liquidity trap and Fed balance sheet greatly expanded.

Actual Financial Balance Sheets (pre-crisis 2008:Q1)
Note: the current Fed balance sheet is extremely different and not representative, so I have used an older balance sheet.
Banks are required to hold reserves against transactions balances.
Reserves are cash plus deposits at the Fed.

Theory of Central Bank Interest Rate Determination
• Definition of transactions money is M1= Cu + D. Assume currency is exogenous. Then analysis the supply and demand for bank reserves, which yields the equilibrium “federal funds rate.” Bold = Fed instruments.
• Demand for R:• Bank regulation: reserve requirement on checking deposits (D).• (1) R > h D• (1’) R = hD In normal times (not now!)• The demand for checking deposits is determined by output and
interest rate:(2) Dd = M(i, Y)• This leads to the demand for reserves by banks in normal times:(3) Rd = h M(i, Y)
• Supply of R:• Fed supplies non-borrowed reserves (NBR) by open-market
operations (OMO). Additionally, banks can borrow at discount rate d. This leads to supply of reserves function:
(4) Rs = NBR + BR(d)• Which yields equilibrium of the market for reserves• (5) h M(i, Y) = NBR + BR(d)
![Page 21: 1 Money, Finance,and the Crisis of 2008-2012. Outline of money section 1.Essence of financial markets 2.Balance sheets 3.Introduction to the supply and.](https://reader030.fdocuments.in/reader030/viewer/2022020117/56649daa5503460f94a97959/html5/thumbnails/21.jpg)
21
• So this shows the way the Fed determines i:
h M(i, Y) = NBR + BR(d)
• Note the three instruments of (normal) Fed policy, h, NBR,
and d.• Essence of modern central banking:
• Banks required to hold reserves against demand deposits
• Fed intervenes through open market operations to set NBR
• The interaction of supply and demand determines short interest rates.
• This affects the entire term structure of interest rates; other asset prices; and the economy.
• However, in times of stress (financial crises), the central bank can use non-conventional tools – this is the central issue of US monetary policy today.
