2. Part 1: How to assess the EA MP compared to the US MP at the ZLB?
- There is a EA-US yield decoupling now larger & longer than in the mid-2000s
- It can be largely explained by ≠ R stars, expected accommodation & fundamentals
Part 2: Is there an impact of the EA MP on the US?
- Little literature about EA MP effects on US markets (≠ large US MP effects on RoW)
- Event graphs suggest some EA MP spillovers: not more since 2014 on US yields but
slightly + on equity & XR (even if XR related to oil price changes & not an objective)
Concluding paradox on the financing of both economies:
despite lower risk-free rates, the Cost of Equity remains ± stable/high
Main messages on EA vs. US Monetary Policies (MP)

1st decoupling 2004m11: 2 years before & after

Spread 10 years GER-US > 50 bps

5. 1… Why a decoupling? The possible role of R star (neutral rate)
Persistent differences in future short-term
interest rates may reflect different R stars
In 2015 (Holston …): EA = - 0.5% ; US = + 0.4%
(estimates surrounded by uncertainty but
now clearly lower in the EA than in the US)

Deeper decrease in the EA may be due to:
- lower productivity growth;
- lower working population growth …

6. 1… The role of CB Communication: expected accommodation
In line with ECB communication,
APP has been expected to grow
EA low yields reflect that market
participants price a persistent
stimulus from the Eurosystem
According to markets in Sept. 2016,
the risk of ECB tapering hasn’t (yet)
been the dominant scenario …

7. Let’s assume basic Taylor Rules (TR),
leaving aside ≠ in R stars; forecasts allow
us to derive a TR differential (in bp):
in 2016 ≈ 120; in 2017 ≈ 70; in 2018 ≈ 30
Thus, over the next 3 years, the average
TR differential ≈ 73bp while the 3y DE-
US spread is ≈ 150 bp
=> Fundamentals would account for half
of the 3y spread observed today
Taylor Rate = TR 2016 2017 2018
EA: HICP 0.2 1.2 1.6
HICP – target (1.9) -1.7 -0.7 -0.3
GDP 1.7 1.6 1.6
Δ GDP potential 0.2 0.1 0.1
Impact on basic TR -2.5 -1.0 -0.4

GDP 1.8 2.0 2
Δ GDP potential -0.5 -0.3 -0.3
Impact on basic TR -1.3 -0.3 -0.1
TR differential -1.2 -0.7 -0.3
Forecasts based on ECB’s MPE and on the FOMC, both in September 2016
Basic TR: coefficients on infl. / GDP = 1.5 / 0.5 (same in EA & US); potential growth: 1.5% in EA & 2.25% in the US

1… Why a larger/longer decoupling? The role of fundamentals

8. Part 1: How to assess the current EA Monetary Policy (MP)?
- The EA’s yield decoupling with the US is larger & longer than in the mid 2000s
- It can be explained by R star, expected accommodation & fundamentals
Part 2: Is there an impact of the EA MP on US markets?
- Little literature about EA MP effects on US markets (≠ large US MP effects on RoW)
- Event graphs suggest some EA MP spillovers: not more since 2014 on US yields but
slightly + on equity & XR (even if XR related to oil price changes & not an objective)
Concluding paradox on the financing of both economies:
Despite lower risk-free rates, the Cost of Equity remains ± stable/high
Main messages on EA vs US Monetary Policies

9. Part 2: EA/US short-term yield correlation & US conundrum
9
Rolling correlations (1-m windows)
for 3Y zero coupon yields DE & US
Even if there is decoupling, there is currently a US conundrum;
Similar trends in markets’ inflation expectations despite different inflation forecasts.
Does EA MP contribute to the decline in the US yield curve?

10. Many studies published about the US impact on the RoW:
on EMEs > on AEs, with similar channels for MP & Unconventional MP
Less is written on the impact of EA UMP (recently implemented only):
- Smaller spillovers (if any) than from the US MP: Rogers …, 2014 (2007-2013, VAR)
- Positive impact on US equities & confidence but less on 10y sovereign
Rogers …, 2014 (2007-2013, VAR) ; Fratzscher …, 2016 (2007-2012, Panel)
- Via SMP=portfolio rebalancing; OMT=confidence; APP=signal: Georgiadis 2015
Caveat: this literature relies on econometric tools that provide averaged results over
the samples, and cannot bring strong insights on what happened recently
(except when models include Time-Varying parameters)

2.1. Literature survey on MP effects on Financial Markets

11. US sovereign conundrum, although U ↘, core CPI ↗ & Fed tightening
Do EA MP spillovers play a role?
- according to Goldman Sachs, ECB QE accounts for ≈ 1/3 of the 10y rate drop,
=> higher asset prices & stronger USD since the end of 2013
- Large EA spillover on US long-term inflation expectations: Ciccarelli …, 2015
- Weaker EA prospects & easier financial conditions => downward trend in LT
US yields: Buitron …, 2015
- APP boosted global markets & $, but no effect on US bonds (Georgiadis …, 2015)
- Markets view US bond yields as ‘anchored’ by EA yields (K. Guha, Sept. 2016)
=> Diverging results may be complemented by BDF work in progress …

ECB Governing Councils’ Announcements & Daily Changes in 10Y rates
Some spillovers but no evidence that the
US yield reaction is systematically larger as
of mid 2014. If anything, there is more
upward impact (62% vs 53% before)
Jan. 2010 - May 2014: 53 GC
Jun. 2014 - Aug. 2016: 21 GC
Method: distribution of changes in the 10Y
zero coupon yield observed between the:
- Wed. cob before an ECB Gov. Council
- Thur. cob of that ECB GC (both in US time)
Nota: expected changes already discounted
In annex, for inflation expectations, the
outcome is broadly similar
On average: +0.02% after 06-2014
+0.01% before

17. 2.1. Literature on Monetary Policy effects on Financial Markets
17
Literature focuses on US MP impact on RoW. Its main results are:
- Large spillovers of US -> RoW but less on AEs (Fratzscher..., 2013 (2007-10,
Regressions) ; Bowman..., 2014 (2006-2013, Panel) ; Miranda-Aggripino and Rey, 2015 (1980-2010, Factor
Model + BVAR))
- Similar channels of MP & UMP (Dd, XR, fin. conditions, K flows)
- Dilemma vs trilemma, notably for EMEs (Rey, 2015 (1990-2012, Factor model + VAR) ;
Dedola…, 2015 (1980-2013, BVAR) vs XR regime still matters (Aizenman …, 2015 (1986-2012, regress.)
