Rate Disparity

The dilemma of setting interest rates in modern money systems

What must be understood about raising interest rates, is that in modern floating exchange fiat systems, countries raise interest rates on themselves. The rate setting set by a nation's central bank, is what their own treasury must pay on private savings and the country's debt. For currency unions, central banks similarly manage the rate and convertibility of member countries' debts.

The practice of using interest rates to manage the price level goes back to the gold standard.

Yield Curves

Yield curves reflect two different kinds of information.

1. The anticipation of future interest rate settings
2. A premium for longer term securities

Note that even future dated securities may trade very actively, and thus be considered highly "liquid".

Yields of many assets may also reflect risk expectations, but this may be difficult to assess, or in some cases, not applicable.

For fiat in particular, if the risk of convertibility into cash eliminated, then devaluation is possible, but not default.

Temporal Exchange Rates

Interest serves as an exchange rate between money now and money later. This is not simply an expression of time preference, as a debt to pay money, can potentially circulate in markets themselves, or even be used as a payment instrument! As we describe with treasury bonds, they can almost be viewed as merely a different form of money, or nominal purchasing power in a unit of account, which is anchored to their date of maturity, rather than having a specific denomination today.

A temporal exchange rate allows for two things:

1. For traders to speculate on real rates.
2. To devalue the currency in relative terms by offering a yield.

The Most Valuable Traded Asset Likely has a Zero Discount Rate

In this sense, we are talking about the rate of discounting used for present value calculations(not the discount window rate).

The discount rate is the assumed return that is possible for investors, when adjusted for risk. The discount rate could be denominated in any unit of account, whether that is dollars, commodities like gold, silver, or food, or financial assets like bonds.

If there is a uniform discount rate possible for any size of principle, then it is highly probable that the most valuable asset will have that discounting rate. This means that describing the discount rate in terms of the most valuable asset, will be very close to zero.

With enough financial uncertainty large and relatively stable assets tend to set the rate of discounting, rather than the rate of discounting determining the valuation of those assets. In an uncertain financial environment, it is increasingly more difficult for rates and returns to be compared and compete directly.

Yields cannot be assumed to be uniform for widely variable principle amounts

The ephemeral nature of wealth and value, dictates that yields will always be highly sensitive to the amount of your principle. Indeed. the challenge of wealth management, is a storage problem: "can we anticipate and meet our future needs?"

It does not seem appropriate, to compare yields on multi-billion dollar projects, with yields on $10k being invested at a time, when the more wealth you are trying to store, the further into the future it must last. This is because both absolute and relative yields matter. An absolute yield is simply subtracting the final value of a portfolio from the value of the principle.

The need for more overhead on large projects and large portfolios, makes any direct comparison of yields unreasonable. This is also true of living organisms, larger organisms tend to grow more slowly and have a longer reproductive lifecycle period(doubling time).

Prices And Yields are Relative

Inherently, any yield is the relative devaluation of the currency or unit of account. If a bond yields 10%, that means a currency is depreciating 10%, compared to a bond.

Bond Yield Targeting

Instead of using interest rates to try to control the change in value of a currency, it makes more sense to try to control the CPI adjusted yields of treasury bonds. This is best when allowed to float within a range.

While some experimentation may be needed to determine the best yield ranges, one could start with +3%/-2%. If inflation adjusted yields of tsy bonds drop below -2%, then rates can be increased. If these yields rise above 3%, then rates can be lowered.

For more persistent inflation(over 3-4 years), the range may need to be relaxed, with a larger potential upside or downside, for example, +5%/-3%,

Why Inflation Adjusted Securities are Unstable

Inflation adjusted financial assets have the same issue as fixed exchange or pegged currencies. Instead of graceful/gradual failure like equity, it makes the system unstable.

Adjusting rates upward to delay inflation, to stretch it out over a longer time frame, is a reasonable monetarist practice, however, as discussed, targeting inflation, instead of the real yield, also creates instability.

If the policy rate is elevated, then bonds can achieve a positive real yield, even with a high rate of inflation. For example, if the policy rate is 8%, and inflation is 7%, then bonds have a real yield of 1%, which could be considered acceptable. If inflation unexpectedly falls, then the real yield could be as high as 8%, if inflation falls to 0.

Duration: Mechanical Effects of Temporally Anchored Money

When you purchase a security, you are buying a temporal monetary anchor. It pays out a specific amount of money at a specific date.

Entities that don't issue Equity

Equity is a flexible, but costly financing tool. It is flexible in the sense that its value adjusts dynamically, and cannot create insolvency. It is costly in the sense that equity holders retain all the residual value, there is an unlimited upside for equity holders. While pro-active measures can help the different participants in a business to benefit comparably from business success, the design of equity makes the shareholder profit the lowest priority in disbursing payouts in the short-term, but the highest priority in terms of decision making and future gains.

Equity benefits are paid out after all debts, which include wages and other obligations, thus in a procedural sense, equity claims have the lowest priority. But in term of governance and decision making, equity claims are treated as the highest priorities.

There are many financial entities that don't issue equity shares. For many of these, the reason is simply size and complexity.

Debt Valuation

Money without debt has no fundamental value or cost, so the price level is arbitrary.

But once you attach debt to money, then the price level determines the valuation of said debt.

What Mosler Did

Warren Mosler has provided an effective critique of conventional rate policy, and an alternative framework for analysis of the price level:

The price level is a function of prices paid 
by government when it spends, or collateral
demanded when it lends.

It may not be immediately obvious, but this statement also can be applied to interest spending. As discussed interest is an exchange rate for money, in the own unit of account, between two parties at two points in time.

As such, when a government, or any entity, sells a greater amount in the future, for a lesser amount today, they devalue the unit of accout.

The government instigating such a trade is uniquely determining, as they are the monopoly issuer, and can do so at any scale.
