Fungibility refers to the property of a good or asset where
individual units are interchangeable and indistinguishable. In other words, each unit of a fungible asset
is considered identical and can be exchanged or replaced with another unit of
the same asset without any loss of value or change in quality. Examples of fungible assets include money,
commodities, and certain financial instruments. In the case of money, a specific unit of
currency, such as a dollar bill or a digital currency unit, is fungible because
any unit of the same denomination is equal in value and can be used
interchangeably. Similarly, commodities
like gold or oil are often considered fungible because each unit of the same
type and grade is interchangeable with any other unit of the same type and
grade.
Fungibility is a key concept in economics and finance, as it
simplifies transactions and facilitates the liquidity and trade of assets in
markets. Non-fungible assets, on the
other hand, are unique and not interchangeable with other units. Real estate, collectibles, and certain types
of intellectual property are examples of non-fungible assets. Fungibility is lacking in the carbon markets,
even across compliance exchanges. For
the carbon market to move to next level, and be a distinct commodity to be traded
and consumed, this is a necessity. Just
like in the commodities market, for it to function, the market must have
confidence that all producers are working within the same regulatory framework,
to the same standard, such that the market can reliably value all carbon
credits of the same category to the same value, regardless of geographic
origin. There must also be enough of the
market for there to be liquidity.
The basis of the market is a carbon offset credit, or simply a
carbon credit. A carbon offset credit is
a tradable certificate representing the reduction, the removal, or the avoidance
of production, of one metric ton of carbon dioxide (CO2) or its
equivalent in other greenhouse gas emissions. It is called CO2e. The intent is to mitigate climate change by
incentivising and by financing projects that reduce or offset greenhouse gas
emissions. There are, broadly, two kinds
of markets: the voluntary and the compliance.
Voluntary carbon credits do not meet the verification and validation
requirements to be considered a financial instrument. The key to the commodification of carbon
credits is found in the compliance market.
While I may refer to carbon credits as a commodity and a financial
instrument, a financial instrument and a commodity are distinct concepts, but
there can be overlap in certain situations. A financial instrument is a broad term that
refers to various contracts or assets whose value is derived from an underlying
asset, index, rate, or instrument. It
represents a tradable asset that has monetary value. Examples of financial instruments include
stocks, bonds, derivatives such as options and futures contracts, currencies,
and various investment funds.
A commodity, on the other hand, is a raw material or primary
agricultural product that is traded on an exchange. Commodities are typically standardised and
interchangeable with other goods of the same type. Examples of commodities include gold, silver,
oil, natural gas, agricultural products, and base metals.
Financial instruments can be linked to commodities in certain
cases. For instance, financial instruments like futures and options contracts
can be based on the value of commodities. Traders and investors use these derivatives to
speculate on or hedge against price movements in commodities. Some financial instruments are specifically
designed to track the performance of a commodity or a basket of commodities. Exchange-traded funds (ETFs) and
commodity-linked notes are examples of such instruments.
A financial instrument is a broader category that encompasses
various tradable assets, while a commodity specifically refers to raw materials
or primary agricultural products. However,
financial instruments can be created based on the value of commodities,
allowing investors to gain exposure to commodity price movements or manage
related risks. In the case of carbon
credits, it can become a commodity, and because of the nature of the contracts,
and the possible derivatives, it can become a financial instrument.
At the moment, however, there are key differences between the
commodities markets and the carbon markets.
For example, commodities have defined rules on standards and regulations
that must be adhered to. The carbon
markets lack that. The standards are
evolving, and there are different levels of credibility in the different
markets. This explains why the EU ETS
alone takes up more than 90% of all the compliance carbon markets, despite
there being around 30 such markets.
Commodities are abundant enough that while changes in supply and
demand will influence price, there is still liquidity in the market. That is not the reality with carbon
credits. In fact, as we push towards a
more stringent compliance regime, to pave the way for rated carbon credits, we
will face an initial shortage oof such carbon credits because there are not
enough compliance credits to meet the expected exponential rise in demand due
to the implementation of the carbon tax globally.
While we may refer to carbon credits a commodity, commodities are generally
raw materials that may be consumed to produce finished products. The commodity itself is a physical product. That product may be tested, assessed, and
validated, which creates confidence in its fungibility. Carbon credits are smart contracts, sometimes
on a blockchain. They are intangible products
based on a physical asset, the carbon sink. It is because of this intangibility that the
market confidence for carbon credits can only be based on the stringent
compliance standards and regulatory framework.
It is this point that precludes voluntary credits from being considered
either a viable commodity or a financial instrument.
The intangibility of carbon credits is what feeds the inherent
uncertainty of the product. This is what
needs to be addressed. Analysts,
experts, and market observers have
advanced the idea that carbon credits are like bonds. This is a conceptual comparison, an analogy
used to highlight certain financial characteristics that carbon credits and
bonds may share, such as tradability, market value, and the potential for
generating returns.
Like bonds, carbon credits can be bought and sold in markets, and
their value can be influenced by supply and demand dynamics. Both financial instruments have the potential
to provide financial benefits, although the mechanisms through which they do so
differ. This leads to the debate whether
carbon credits should be treated more like bonds. This implies that market underpinnings such as
ratings, compliance standards, regulatory audits, and insurance drive pricing
and risk scoring. They differ in significant
areas. Bonds represent debt issued by
governments, municipalities, or corporations. When an investor buys a bond, they are
essentially lending money to the issuer in exchange for periodic interest
payments and the return of the principal amount at maturity.
Investors in bonds receive periodic interest payments as income,
and they are typically repaid the principal amount at maturity. Carbon credits do not generate periodic
income. Their value is associated with
their ability to offset or reduce greenhouse gas emissions. Bonds are issued by governments,
municipalities, or corporations to raise capital. The issuer has an obligation to repay the
principal amount and make interest payments according to the bond’s terms. Carbon credits are generated by projects that
reduce or offset emissions. The entities
undertaking these projects may sell the credits to generate revenue, but there
is not a direct obligation to repay a principal amount as with bonds.
In any case, whether we consider carbon credits a commodity or
financial instrument or both, a key contention is the lack of trust in the quality
of the carbon credits, and the associated reputational risk for buyers and
investors. Buyers and investors are
forced to conduct extensive amounts of due diligence prior to executing any
carbon credit transaction, which adds to cost.
Because of this variance in due diligence in the absence o framework,
there is no fungibility. There is also
the challenge for buyers to align their due diligence requirements to wider
message on net zero strategies, and Sustainable Development Goals (SDGs). In the course of this, there is a lack of
understanding, in many quarters, on the differences between reduction carbon
credits, avoidance carbon credits and removal carbon credits.
There are specific areas that need to be addressed, as we work
towards fungibility in the carbon market.
We cannot achieve fungibility for all compliance carbon offset credits,
but we can have fungibility within classes.
That means we have to class them according to type of project. These include cookstove offsets, renewables,
afforestation, reforestation, biochar, peatland, direct air capture, and green
and blue sequestration, among others. Some of these types are not
suitable for the compliance market. For
example, cookstove offset projects are responsible for millions of junk
credits.
As part of the verification and validation process, we need to
consider location, because that has a direct correlation to credibility. From location, we can consider political risk,
regulatory risk, local community engagement, benefit-sharing, relevance to
buyer’s business; geological risk such as natural disaster, corruption, and
even project viability. This is
especially important when we see this in light of the SSGs.
In summary, we need to identify the types of carbon credits for the
compliance market before we create a regulatory framework that encompasses the
points of contention to be addressed. We
need to identify, qualify and quantify the risks. We need a wide variety of strategic partners
from regulators to central banks to project owners to buyers before traction
can be achieved. From this, we need to
work towards a rating system for carbon credits, so that they can be rated, and
eventually made investment-grade. When
we have that, we can apply for carbon credits to be recognised as financial
instruments by elect central banks, and made fungible.
