The PBoC, the ECB, the Riksbank and the Fed are all looking into
digital currencies. We look at the status and the potential repercussions.
Could we enter a period of speculation in the CNY ahead of the launch of the
digital renminbi?
CBDC (central bank digital currencies) is one of the most exciting
and important topics at the moment. Through the last decade the transition from
physical fiat money to digital payments has formed our society more than ever.
With the evolution (or even revolution) in digital payments services, a
possible cashless society doesn’t seem that far away in several countries. New
services as MobilePay in Denmark, Swish in Sweden, Venmo in the US etc. have
given the end-users a new and more flexible solution when transferring money privately.
Furthermore, increasing focus on money laundering, terror financing and KYC
combined with the before-mentioned flexibility has lowered the cash share as a
payment instrument.
These are obvious reasons for a central bank to investigate a
digital currency setup, but likely not the only drivers. Could it be that a
digital currency allows for a more direct type of QE as a policy instrument?
Our main takeaways
We expect China to launch the digital renminbi at the Winter
Olympics in 2022 and wouldn’t rule out that markets speculate in a positive
repricing of the renminbi ahead of the launch.
We expect all major central banks to launch digital currencies over
time, which opens the door for actual “people’s QE” compared to the current
“asset QE”.
We wouldn’t rule out that a launch of a digital currency would make
it easier for central banks to go even deeper into negative territory on the
policy rate, but this is clearly not a story for the next few years. We
ultimately rather expect digital currencies to lead to higher interest rates.
China is leading the race, but Sweden is the forerunner of Western
economies in the CBDC development
A CBDC is a currency issued by the central bank as a digital
version of their physical currency. This currency will be placed in a digital
wallet either on a phone or in a “node”. Each and every person (and potentially
company) is likely to get such a digital wallet directly in the central bank
over time. The difference between a CBDC and the money placed in your bank
account today is that in the case your bank goes into bankruptcy, your money
(minus an insured sum) will be lost. A CBDC on the other hand is secured by the
central bank, meaning it cannot be lost but only lose value due to inflation; 1
digital dollar will always be equal to 1 dollar.
The big question is whether these wallets will carry interest rates
or not. In principle the wallet should carry an interest rate alongside the
deposit rate of the central bank, which in the case of the ECB, the Riksbank
and the Danish central bank would be a negative carry. Will central bankers opt
to free digital wallets from a negative interest rate? In such case they would
clearly need to limit the size of the wallets. Fabio Penetta from the ECB has
already multiple times mentioned a potential limit at EUR 3.000 for the Euro
wallet to prevent this potential problem.
The
current first mover in the CDBC developing process is the Peoples
Bank of China (PBOC) with their Digital Currency Electronic Payment (DCEP).
They are currently testing their CBDC in a large-scale pilot project and hope
for a full implementation by the Winter Olympics 2022. Most countries are not
near as far in the development of digital currencies, in addition multiple
emerging and frontier markets don’t have the required know-how and money to
develop the infrastructure even though some of these countries would be the
potential biggest gainers by having a CBDC because their commercial banking
infrastructure is very unstable. This leaves a decent space for a Chinese
attempt to “reservenize” the Renmbinbi via opening the CNY DCEP to other
countries or via selling the infrastructure to other countries.
If
China gives other countries direct access to their DCEP, then the buying
pressure in the DCEP would give the PBOC an incentive to issue more DCEP
“nodes”. This could lead to a new dollarization or more correctly a
“yuanization”, and clearly be a risk for the USD reserve status over time
should the Chinese digital currency project succeed. We have noted how the
USD/CNY has clearly traded lower during the pilot test periods of the digital
renminbi. Maybe an early signal of what to expect when we get closer to an
actual launch?
The
latest test ran from 10 to 23 April including 500,000 persons, which is 10 times more than the
first test in October 2020. However, we are still far away from a “real” world
scenario so it will perhaps be a small-scale launch by the Winter Olympics.
Sweden
is currently a clear frontrunner in the CBDC development in the Western
countries. In contrast to China, they are using a blockchain-based technology
as their digital krona is based on the DLT technology. It is Accenture which
has been hired for the job at a contract running from 2019 until 2026, if all
options for extensions are exercised. In April this year they published the results and conclusions of the first
pilot project. One of the current focus areas that needs to be
tested is if the DLT technology can handle retail payments (China said it could
not). Another important topic is the way that the e-krona will be stored, where
they mention three different options, each with advantages and disadvantages.
The
user stores a private key and CBDC locally for example on their phone, in
an app or on a card:
Most
cash look-a-like, if you lose your storage (eg phone), your money will be lost
precisely as when you lose your cash in a wallet.
The
user stores a private key locally but the CBDC is stored in the network in a
“node”:
With
the money stored in a node, you will not lose your money in the case of losing
your key.
The
user stores a private key and the CBDC in the network in a node
Nearly
identical to our current bank accounts and associated payment services, only
difference is that it will be a liability against the central bank instead of
your commercial bank.
The
ECB and the Fed are not as far as China and Sweden in their digital Euro and
Dollar projects. In the same interview where the ECB’s Fabio Penetta mentioned
a possible limit at EUR 3,000 of the wallet, he also mentioned 2026 as the
earliest launching date.
The
research about a digital dollar is run by the digital
dollar project, which is a non-profit partnership between Accenture
and the Digital Dollar Foundation, and a partnership between Boston Fed and MIT. These projects are
supposed to run as complements and therefore both contribute with insightful
research to the CBDC environment. Even though the digital dollar project is
about to launch five pilot projects, the US is still far behind China and
Sweden. However, after a message
from Powell an escalation of the digital dollar could be on the
cards.
What are the repercussions for central banks,
interest rates and FX developments?
As we
mentioned in the beginning, central banks are likely inclined to look into
digital currencies for several reasons. First, it is easy to monitor
transactions. Second, they may help protect simple savers from negative
interest rates. Third, it fits hand in glove to the de-cashing trend of the
most recent decades.
We also find that a digital currency may increase the size of the tool-box of
the monetary policy. Currently, central banks buy assets (mostly bonds) from
financial counterparts in return for fresh digital reserves (an asset swap),
but these reserves are parked in the commercial banking system and hence rely
on the usual transmission mechanism before reaching the real economy. If a
digital currency is in place, then the central bank may just as well decide to
transform the asset swap QE into a form of People’s QE.
Instead
of buying 120bn worth of US Treasury bonds a month, the next step may simply be
that each and every person’s digital wallet is revalued by 120bn divided by the
population size every month. This would also fit hand in glove with the new
woke style of many central banks.
This is by the way almost what is already happening in practice, since the Fed
is buying the bonds which are issued to pay each American adult 300$s via
direct transfers a week currently. We wouldn’t rule out that such an
infrastructure hypothetically opens the door for negative interest to an even
larger extent, but a People’s QE programme would on the other hand prove much
more efficient than asset QE in terms of creating inflation. We hence rather
bet on higher, than lower interest rates as a result of a potential series of
launches of digital central bank currencies.
A
potential early adoption of the digital renminbi by frontier and emerging
markets may also open the door for a de-dollarization and a yuanization (Global: Bitcoin, the Chinese and the dollar)
of the global economy.
As
China’s GDP and role in world trade continue to grow, it seems natural to
expect that countries, especially its neighbouring countries, will to a larger
and larger extent start to use China’s currency as both invoicing and financing
currency. And if demand for China’s currency increases, the appetite for
dollars will decrease, which – keeping everything else equal – will lead to a
continued de-dollarization in global FX reserves. A process that is currently
already slowly in the making.
For all that, the dollar is likely to remain the world’s most important reserve
currency for many years, perhaps even decades ... But the Chinese first-mover
advantage on the CBDC agenda may prove to be an important milestone for FX
markets and we certainly wouldn’t rule out a continued clear strengthening of
the CNY ahead of the launch of the digital renminbi in 2022.
