Monetary policy货币政策

Stable prices (Typical) 稳定物价（典型功能） PBoC: “The objective of the monetary policy is to maintain the

stability of the value of the currency and thereby promote economic growth”

中国人民银行：“货币政策的目标就是要维护币值稳定从而促进经济发展。” Full employment (unusual for an OECD central bank)提高就业水平（对于一个 OECD 国家的中央银行，不是很寻常的职能）

Financial stability (contain systemic risks) 金融稳定（包含系统风险） Supervision & Regulation of banks (Safety/Soundness)对于银行的监管和政策规定（安全性 / 稳健性）

Payments system 支付系统 Government’s bank 政府的银行

3. Traditional Monetary Policy传统的货币政策

3.a. Monetary Policy: Dual Goals货币政策：双重目标

8

Price stability 价格稳定Sustainable growth / full employment 可持续增长 / 充分就业

This This ““dual mandatedual mandate”” is distinct. is distinct. 这个“双重使命”非常独特。这个“双重使命”非常独特。

3.a. Trying to achieve monetary policy goals is a bit like:

9

Driving in the fog on a curvy road with cliffs on both sides, where there are long and variable lags between when you turn the steering wheel and when the wheels actually turn.

The cliffs on one side represent inflation and the cliffs on the other side represent recession and unemployment.

Central banks try to figure out “targets” so that they neither:

Turn the wheel too hard and unexpectedly get inflation orTurn the wheel too little and fall off the cliff into a recession.

The fog represents how difficult it is to actually see what is going on in terms of employment, inflation, and growth. People debate which way the wheel should be turned.Who are those people?

3.a. 争取达到货币政策的目标就像是：

10

在大雾里边开车，路上弯弯曲曲，两边都是悬崖，而且你在打方向盘的时候，方向盘和车轮之间还存在长短不一的时间差

路两边的悬崖，一边代表通货膨胀，一边代表衰退和失业

中央银行需要找到“目标”，这样他们可以避免：把方向盘打得太猛以至于造成预料之外的通货膨胀，或者把方向盘打得不够从而造成经济衰退

路上的雾代表着实际上很难看清真实的失业，通货膨胀，以及经济增长的情况人们争论究竟应当怎样打方向盘那这些争论的人是谁呢？

3.b. Monetary Policy: Structure

11

Who: Federal Open Market Committee (FOMC)5 Federal Reserve presidents vote. All 12 attend.7 members of the Board of Governors[Monetary Policy Committee for PBoC]

When: FOMC typically meets 8 times per year[Quarterly for PBoC]

What:FOMC Directives / Announcements / Statementshttp://www.federalreserve.gov/newsevents/press/moneta

ry/20130918a.htm[http://www.pbc.gov.cn/publish/english/970/index.html

for PBoC]

3.b. 货币政策：结构

12

相关方： 美国联邦公开市场委员会 (FOMC)全体 12 位主席出席， 5 位主席轮流投票7 位理事会成员[中国人民银行货币政策委员会 ]

时间： FOMC 通常在一年之内会面 8 次[中国人民银行是每季度一次 ]

做什么 :FOMC 的指令 / 公告 / 声明http://www.federalreserve.gov/newsevents/press/moneta

ry/20130918a.htm[http://www.pbc.gov.cn/publish/english/970/index.html

for PBoC]

3.b. Example: FOMC directive 9/18/07

13

The Federal Open Market Committee decided today to lower its

target for the federal funds rate 50 basis points to 4-3/4 percent.

Economic growth was moderate during the first half of the year, but the tightening of credit conditions has the potential to intensify the housing correction and to restrain economic growth more generally.  Today’s action is intended to help forestall some of the adverse effects on the broader economy that might otherwise arise from the disruptions in financial markets and to promote moderate growth over time. 

The Committee judges that some inflation risks remain, and it will continue to monitor inflation developments carefully. 

In a related action, the Board of Governors unanimously approved a 50-basis-point decrease in the discount rate to 5-1/4 percent. 

3.b. 举例：美国联邦公开市场委员会指令 9/18/07

14

美国联邦公开市场委员会今天决定将其联邦基金利率降低 50 个基点至百分之 4-3/4 。

今年上半年的经济增长相对平缓，但是信贷条件的紧缩将有可能加重房产市场的调整，并且在更广泛的层面上抑制经济增长。今天的决定将帮助预先防止由于金融市场的不稳定给经济带来的负面影响，同时在未来促进经济适度增长。

美国联邦公开市场委员会判断一定的通货膨胀风险仍然存在，并且将继续小心监控通货膨胀情况的发展。

与以上决定相辅，理事会一致通过将贴现率增加 50 个基点至百分之 5-1/4 。

3.b. FOMC

15

• There was a large change in the nature of the FOMC statement following the crisis: quantitative easing.

金融危机之后，在 FOMC 的声明中出现了比较大的变化：量化宽松

• We need to understand the mechanics of monetary policy to 我们需要了解货币政策的技术细节以便understand why this change happened, and理解为什么会出现这样的变化what this means for business conditions in the

future and around the world.这个变化对于商业环境和世界其他市场的影响是什么

Fed influences the money supply primarily by using two tools:

美联储主要通过使用下边的两个工具来影响货币供应量：Open market operations 公开市场操作Discount loans 贴现贷款

To link the analysis of monetary policy to bank balance sheets, it is helpful to examine how these tools influence bank reserves.

为了能够将针对货币政策的分析同银行的资产负债表联系起来，很有必要解释一下这些工具是如何影响银行的准备金水平

注意：向有困难的银行通过贴现贷款而避免市场恐慌

这是：美联储作为最后贷款人的角色

3.c.4.Targeting

27

How does the Fed know the appropriate value of securities to purchase or the rate at which it should charge banks to borrow (discount loans) or the level of reserve requirements when changes in these actions only influence prices and employment with long variable lags?

One way is for the Fed to target the federal funds rate because its an easy-to-observe, though limited, indicator of credit conditions. Example:

Buy Treasury securities through Open Market Operations until the targeted FFR is achieved.

Then, wait, and see how this influences prices and unemployment.

Then, decide if it wants to alter the targeted FFR.

3.c.4. 目标设定

28

美联储是如何知道究竟购买多少有价证券，或者应当向银行收取多少借款利息（贴现贷款），或者当上述的这些行动仅仅会对市场价格水平和就业率情况产生很长的滞后作用的时候，商业银行的存款准备金应该维护在什么水平？

一种方法就是美联储可以通过设定联邦基金利率目标，因为这是一个虽然有限，但是很容易观察的有关信贷条件的指标。例如：

在公开市场上购买国债，直到达到联邦基金目标利率为止然后，观察这样的行动如何影响物价水平和失业情况然后决定是否改变联邦基金的目标利率

b. Fed implements quantitative easing 美联储开始实行量化宽松政策

c. New FOMC statement 新的 FOMC声明

d. “New” balance sheet “新的”资产负债表

e. Challenges: “Tapering” 挑战：“逐渐减少”31

4. Non-Traditional Monetary Policy

非传统的货币政策

4.a. Traditional Monetary Policy did not work

32

By 2009, the Federal Funds Target Rate had fallen to zero.It was no longer an effective indicator of credit

conditions.Also, because of liquidity fears, short-term interests

became “disconnected” from longer rates, which further reduced the usefulness of targeting the FFR.

Banks did not use the discount window much because of the stigma associated with borrowing directly from the Fed.

But, there were fears of deflation, which would push the real value of debt up and would push real wages up (and hence encourage more unemployment)

What to do?

4.a. 传统的货币政策失效

33

到 2009年，美联储的联邦基金目标利率降低到 0联邦基金利率不再能够真实反映实际的信贷情况还有，由于对于流动性的恐惧，短期利率和长期利率

“脱钩”，这更造成了联邦基金目标利率的有效性商业银行不再经常使用贴现窗口这一工具，因为从

美联储借款往往充满了屈辱但是，市场上也存在对于通货紧缩的恐惧。通货紧缩将推升实际的债务总值，以及工资水平（因而将会导致更高的失业率）

那怎么办？

4.b. Fed adds “Quantitative Easing” (QE)

34

QEQE1: 11/2008 - 6/2010: Large-scale asset purchases

of $600 billion of mortgage-backed securities from banks.

QE2: 10/2010 – 6/2011: large-scale purchases of about $600 billion in long-term Treasury securities.

QE3: 9/2012 - … : $85 billion/month of mortgage-backed securities and long-term Treasury securities.

Boosted the Fed’s balance sheet by almost $3 trillion.Also: “Forward Guidance”

Fed seeks to “guide the economy” by telling us what they will do in advance, especially to FFR and QE

4.b. 美联储推出了“量化宽松（ QE ）”政策

35

量化宽松（ QE ）QE1: 11/2008 - 6/2010: 大规模地从商业银行手中购买了价值 6000亿美元的抵押贷款证券

QE2: 10/2010 – 6/2011: 大规模地购买了价值6000亿美元的美国国债

QE3: 9/2012 - … : 每月购买价值 850亿美元的抵押贷款证券和美国长期国债

将美联储的资产负债表总额增加了近三万亿美元还有：“前瞻性指导”

美联储尝试着通过告诉我们它将怎样做，特别是怎样设定联邦基金利率和量化宽松的规模，来“指导经济的走势”。

4.c. FOMC: statement: Sept. 18, 2013

36

Information received since the Federal Open Market Committee met in July suggests that economic activity has been expanding at a moderate pace… the unemployment rate remains elevated.

Apart from fluctuations due to changes in energy prices, inflation has been running below the Committee's longer-run objective, but longer-term inflation expectations have remained stable.

The Committee expects that…economic growth will pick up from its recent pace and the unemployment rate will gradually decline

4.c. FOMC: 2013 年 9 月 18日声明

37

在联邦公开市场委员会（ FOMC ）七月份会议之后，我们收到的信息表明经济活动的开展速度比较缓和 … 失业率维持在比较高的水平

除了由于能源价格的变化造成的波动之外，通货膨胀水平处于委员会的长期目标之下，但是长期通货膨胀的预期保持不变。

委员会预计 … 经济增长的速度将会从现在的水平上开始加快，而失业率将会逐渐降低

Continued

38

the Committee decided to await more evidence that progress will be sustained before adjusting the pace of its purchases. Accordingly, the Committee decided to continue purchasing additional agency mortgage-backed securities at a pace of $40 billion per month and longer-term Treasury securities at a pace of $45 billion per month.

highly accommodative stance of monetary policy will remain appropriate for a considerable time after the asset purchase program ends and the economic recovery strengthens. the Committee decided to keep the target range for the

federal funds rate at 0 to 1/4 percent and [it] anticipates that this exceptionally low range for the federal

funds rate will be appropriate at least as long as the unemployment rate remains above 6-1/2 percent,

inflation between one and two years ahead is projected to be no more than a half percentage point above the Committee's 2 percent longer-run goal, and longer-term inflation expectations continue to be well anchored

继续

39

委员会决定在调整其购买规模之前，还需要继续等待收集一些更多的证据，现在的购买速度将持续。因此，委员会决定将继续按照每月 400亿美元的规模购买抵押贷款证券，以及每月 450亿美元的规模购买美国长期国债。

在资产购买程序结束之后，和经济复兴到来之前的很长一段时间内，货币政策将维持在一个高度适应的姿态委员会决定将其联邦基金目标利率维持在 1/4百分点，并

且委员会认为，只要是失业率水平在 6-1/2百分比之上，那么

联邦基金利率维持在这个非常低的水平就是非常适合的。通货膨胀率在未来的一到两年内，预计将不会超出委员会

所设定的 2% 这个长期目标的 0.5 个百分点，并且，长期通货膨胀的预期一直处于很好的控制之内

4.e. Fed’s challenges

45

Since the economic recovery is weak, it continues to:Target the FFR at about zero.Conduct large-scale asset purchases of long-term

assets to push long-term interest rates down and stimulate economic activity.These are shrinking in size though as the Fed tapers down QE.

But, five years of expansionary monetary policy creates risksUnprecedented reserves … inflation risk (why is

inflation bad)Induce investors to purchase stocks with interest

rates so low.

4.e. Fed’s challenges美联储面临的挑战

46

由于经济复兴的趋势很弱，美联储不得不持续：将联邦基金目标利率设置在接近于 0大规模购买长期金融资产以便压低长期市场利率，从

而刺激经济发展这种购买活动在规模上正在变得越来越小，因为美联储在不断消减 QE 规模

但是，持续了五年的宽松的货币政策也产生了风险：从未有过的准备金规模 … 通货膨胀风险 （为什么通

货膨胀是不好的呢？）利率如此的低，诱导投资人购买大量股票

4.3. Fed’s Challenges and Tapering美联储面临的挑战： QE逐渐减少

48

How rapidly can the FED reduce its purchases of long-term Treasury and mortgage-backed securities: “Tapering?”

美联储削减国债和抵押贷款债券购买规模的速度有多快：“逐渐减少”？

How will the Fed know that economic growth has reached its “long-run potential” rate, or when unemployment is at some “natural” level, so that it knows when to “taper?”

美联储如何知道什么时候经济增长到达了其“长期的潜力水平”，或者，失业率降低到了“自然水平”，然后可以开始削减 QE ？
