1 Central banking before and after the crisis Francesco Daveri
2 The issues Today’s monetary policies in place all around the world are super-expansionary What does “super-expansionary” mean in practice? Super-expansionary with respect to what? More generally, how does a Central Bank formulate its monetary policy? Which goals, which instruments? How is this policy actually implemented?
Policy rates at zero for a decade (not forever, though)... 3
... But also the quantity of Central Banks’ money has exploded since 2008-q4.. 4
Outline Central banking in normal times Tools? Goals? Central banking in “abnormal” times During and after the crisis 5
6 The tools of central banks Open-Market Operations The Fed conducts open-market operations when it buys Government bonds from or sells government bonds to the public: When the Fed buys government bonds, money supply increases. Money supply decreases when the Fed sells government bonds. Reserve Requirements The Fed also influences money supply with reserve requirements. Reserve requirements are regulations on the minimum amount of reserves that banks must hold against deposits. Changing the Reserve Requirement: The reserve requirement is the amount (%) of a bank’s total reserves that may not be loaned out. Increasing (decreasing) the reserve requirement decreases (increases) money supply Changing the Discount Rate The discount rate is the interest rate the Fed charges banks for loans. Increasing (decreasing) the discount rate decreases (increases) money supply
7 The open market operations of the Central Bank affect its balance sheet The assets of the central bank are the bonds it holds. The liabilities are the stock of money in the economy. An open market operation in which the central bank buys bonds and issues money increases both assets and liabilities by the same amount.

9 The role of monetary policy We – as citizens - are normally concerned about inflation and growth (want low inflation and high growth). Central bankers are delegated to achieve – a combination of - these goals Monetary policy is supposed to keep GDP as close as possible to its long-run full employment level as well as inflation close to target (may be 2%) Two kinds of shocks: Aggregate demand (eg. House prices or stockmarkets fall) Short run aggregate supply (eg. oil or commodity prices or wages going up)
The central bankers’ problem of today: low growth in Europe and low inflation in EZ and Usa 10
Many worried about the risk of deflation 11
12 How monetary policy is implemented: the Taylor rule In practice, most central bankers implement inflation targeting following an unofficial rule of thumb in setting the policy rate. This is the Taylor Rule (from John Taylor, Stanford economist): R t = c ( - * ) + d (output gap) R = target policy rate (e.g. discount rate) * = long-term goals for inflation (2%?) = actual inflation c, d = positive constants, measuring CB response to deviations of inflation and output from their long-run values (output gap=y-y * ) NOTE: Given the delays of effectiveness of monetary policy (it takes time for interest rate cuts to affect market rates), it is the EXPECTED inflation and output gap that matter for the Taylor rule
13 The four implications from the Taylor rule 1: economy in long run equilibrium 1) If the economy is OK, do nothing. As = * and y=y *, the economy is in its long-run equilibrium. So R =0, i.e. the discount rate should stay constant
14 The four implications from the Taylor rule 2: Aggregate demand shock 2) As the economy overheats (eg positive AD shock), R should go up for two reasons: > * and GDP>GDP *. The opposite if economy hit by negative AD shock
15 The four implications from the Taylor rule 3: Aggregate supply shock 3) When the economy is hit by a supply shock, the Taylor rule gives ambiguous indications on what to do with R As > * R should go up YET as Gdp1. When faced with inflationary shock, the CB goal is to cool the economy down. To do this, CB must raise R by more than the increase in . Otherwise, the real interest rate goes down (and the economy does not cool down)
16 The four implications from the Taylor rule 4: asset market shocks 4) What should central bankers do with asset (foreign exchange, stock, bond, housing) markets? If CB follows Taylor rule, “do nothing” is a good policy, unless asset price behavior is a threat to stability of future inflation or GDP
17 The blue line shows what the Fed actually did The Fed and the Taylor rule
What went wrong with monetary policy before the crisis? Before the crisis: based on the Taylor rule, discount rates kept too low for too long (during the second half of the 1990s and ) This conclusion stems from today’s hindsight, though US productivity data (see next slide) were so good that most observers believed that a new Internet-based economy was around and therefore that the output gap was relatively low – so no need to raise the discount rate even when faced with very fast Gdp growth 18
Monetary policy in “abnormal” times Monetary policy in abnormal times MP during and after the crisis 20
21 The Fed during the crisis: aggressive moves Since August 2007, the Fed has responded aggressively to the crisis. The Federal Open Market Committee (FOMC) began to ease monetary policy in September 2007, reducing the target for the federal funds rate by 50 basis points. As indications of economic weakness proliferated, the FOMC brought down its target for the fed funds rate by a total of 325 basis points by the spring of This response stands out as very rapid. Once financial and economic crisis gained momentum, another set of cuts for fed funds target rate by an additional 100 basis points in October 2008 half of that reduction was part of unprecedented coordinated interest rate cut by six major central banks on October 8, 2008 (including China’s) Dec 2008: further target rate cut to range of 0-25 basis points Since then, no major changes. Expectation of rate increases looms, though.
22 What was new this time around: The Fed as a direct lender of last resort During current crisis the Fed has been more active in another role: the lender of last resort Before the crisis: Fed had “discount window” (a virtual teller window where banks could borrow money overnight at the “discount rate”, with discount rate>Fed funds rate). Idea: banks should try to borrow from each other first before coming to the Fed. Result: lending via discount rate was minimal. During the crisis: banks unwilling to lend to each other and so the Fed kept widening the discount window to make it easier for banks to get funding
23 The Fed providing liquidity, then buying “toxic” assets in
24 Why standard policies of the past have been insufficient this time Yet providing liquidity to banks and primary dealers this time was not a solution. Liquidity is not enough when there are concerns about capital, asset quality, and credit risk. So limited willingness of “liquid” intermediaries to extend credit to each other To address these issues, a second set of Fed policy tools provision of liquidity directly to borrowers and investors in key credit markets through purchases of private and public bonds All these tools go under the label of measures of «quantitative easing” to expand credit further when policy rate has gone down to zero. We have seen four waves of QE (see picture). The Fed has currently entered a new phase labeled «Tapering» (gradual decrease of purchases). It is NOT a shift to restrictive monetary policy but just a shift to less expansionary monetary policy.
Was it (all this activism) worth eventually? Yes, super-expansionary monetary (and fiscal) policies have worked. 26
The daily volatility of the S&P 100 (US stock mkt index) declined dramatically … 27 Vix Index = a measure of expected volatility in the Us stock exchange (S&P 500) in the next 30 days Vix at its maximum level with Lehman bankruptcy. Also jumps up when Greek crisis recognized to be pan-European issue (May 2010) and also with sovereign debt crisis (summer-fall 2011) Figure shows that Vix has come down to more reassuring levels after ECB’s LTRO1 and 2. It may not last so low.
The interbank market, quickly back in business in Spreads dangerously up, recently Three-month Libor – OIS Spreads (basis points) 3-month Libor = variable, thus risky, rate. OIS = Overnight Indexed Swap; based on overnight rate, hence certain for fixed by Central Bank. The spread between the two rates is a measure of the functioning of the interbank mkt. If interbank mkt works well, spread is close to zero 28
Stock and commodity markets quickly recovering since early Yet Government bond yields start to seriously diverge in EZ 29
QE (Quantitative Easing) has worked Spreads between corporate and Government bonds, on one side, and AAA rate on the other have fallen 30
15 Memo: Bond Prices and Bond Yields Let’s take a closer look at the bond market. It is the PRICE of bonds that is determined in the bond market. Yet from the bond price, the bond interest rate is determined in turn. Understanding the relation between the interest rate and bond prices will thus prove useful Treasury bills, or T-bills are issued by the U.S. government promising payment in a year or less. If you buy the bond today you pay $P B. If you hold it for a year, the rate of return (or interest) on holding a $100 bond for a year is ($100 - $P B )/$P B. So the higher $P B the lower the rate of return (yield) on the bond Starting from the interest rate, we can figure out the price of the bond using the same formula from which we learn that there is a negative relation between bond price and bond yields
How about the ECB? 32
The ECB during the crisis: Trichet’s measures... Under Trichet (former ECB chairman before Draghi), ECB more cautious than the Fed and the Bank of England 2009: Fed & BoE slashed interest rates towards zero and started QE (buying government bonds with central-bank money) ECB was reluctant to cut its main rate below 1%. Resisted idea of buying government bonds directly. The Maastricht Treaty forbids this. Yet Trichet adopted his own non-standard measures. Unlimited loans to commercial banks for up to 1 year against a broad range of collateral. Effect? Similar to Fed and BoE Quantitative Easing A flood of liquidity from €442 billion auction of 1-year ECB loans in June 2009 pushed short-term interest rates close to US and UK levels Banks used much of the cash to buy government bonds, driving down long-term interest rates 33
... And Draghi’s silent bazooka Then Draghi came in and, two years on, has repeated the trick. Faced with: renewed recession; a bank-funding crisis; investor revulsion against all but the safest euro-zone Goverment bonds on December 8 th, 2011, the ECB announced the following: “It would provide unlimited funds for 36 months at its main interest rate (which it cut to 1%), at two auctions. The first of these, on December 21st, attracted bids of €489 billion. (The second occurred on Feb 29, 2012). That doubled the amount lent for one year in June 2009, and has had similar effects. Overall, 1 trillion euros: 131% of total European bank bonds maturing in 2012 and 72% for 2012 and 2013 combined. European banks are now effectively pre-funded through to
35 The ECB total assets: up with LTRO, then down as commercial banks repay their loans
The ECB “silent bazooka” has worked as well: sovereign bond yield curve brought down 36 Overnight interest rates have fallen dramatically. Longer-term bond yields for investment-grade eurozone countries have dropped, too
