Discussions about interest rates and the US Federal Reserve account for a disproportionate quantity of monetary information.
This is as a result of the Fed not directly influences international interest rates – and interest rates have an effect on all asset costs and currencies, and thus our funding returns.
But how, and why? The best solution to perceive is by instance.
If you place R100 right into a one-year funding (let’s name it a ‘bond’) that earns a hard and fast 25% interest each year, it’s simple to see that in a yr’s time your R100 could be value R125.
Put one other method, at this 25% interest fee, R125 of capital in a yr’s time is value R100 of as we speak’s cash.

Now say the authority that decides what the interest fee is – let’s name them central banks – modifications the interest fee (for brand spanking new bonds) to twenty% each year moments after you will have invested your R100 into the bond. Your bond nonetheless earns 25% each year because it was mounted at the earlier interest fee and not the new 20% fee.
All new bonds of R100 will nevertheless solely be value R120 in a yr’s time.
Yet your bond will nonetheless pay out R125 in a yr’s time, and is thus now extra worthwhile than it was a second in the past. Yay!
So, at 20% each year interest fee, how a lot will R125 be value in a yr’s time? Well, will probably be value the similar quantity as no matter we would want to speculate as we speak to receives a commission out R125 in a yr’s time. Simple maths can work this out, as follows: (R125 x 120)/100 = R104.17.
Let’s logic-check this: With a 20% each year interest fee, if I make investments R104.17 for a yr will probably be value R125 in a yr’s time (=R104.17 x [1+25%]).
What does this reveal about interest rates?
This instance reveals us that by altering the interest fee, the central financial institution has modified the worth of your funding.

While a fixed-rate bond is straightforward to know, companies even have anticipated future money flows. These are unsure and extra risky than fixed-rate bonds, however the future money flows (or the market’s expectation of them) is kind of actual.
Thus, altering the interest fee modifications the worth of these future money flows from companies – and since shares on international inventory markets are fractional possession in these companies, it’ll have an effect on the share costs of all firms.
Therefore, central banks have an effect on interest rates and interest rates have an effect on debt and fairness markets.
How does the Fed slot in?
Countries don’t exist in isolation and capital flows throughout (most) borders through forex.
If I’m a worldwide investor and can make investments my capital right into a ‘Country A’ to get a ten% return or ‘Country B’ to get a 15% return – all else being equal – I’ll take my capital, promote the forex of Country A (weakening it), purchase the forex of Country B (strengthening it) and make investments it in Country B to earn a 15% return.

I is perhaps a small investor, however multiply this transaction by the thousands and thousands of market contributors on the market and the huge sums of capital the international market comprises …
Thus, interest rates additionally have an effect on currencies.
More subtly, the distinction between international locations’ interest rates impacts currencies.
And if this distinction is simply too giant, then the low-interest-rate nation’s forex will weaken considerably (lifting its imported inflation fee and demanding a better interest fee) and the high-interest-rate nation’s forex will strengthen considerably (maybe even pushing its inflation into deflation, demanding interest fee cuts to stimulate the financial system).
The international reserve forex
Enter the US greenback. Following World War II and the Bretton Woods Agreement of 1944, the greenback was pegged to gold, and most different currencies had been pegged to the greenback.
While the gold peg has fallen away, the greenback continues to be the international reserve forex – used for worldwide commerce (and apparently the stuffing of presidents’ couches) and central financial institution reserves, and nearly all commodities in every single place are quoted in {dollars}.

It is on this method – with the greenback as the international reserve forex and the US central financial institution (the Fed) deciding the interest fee that {dollars} can earn – that this central financial institution not directly dictates the course, fee of change, and final degree of international interest rates.
(Assuming that different central banks in international locations whose currencies are usually not the greenback don’t need their currencies to blow out towards the greenback; taking a look at you, Turkey …).

At this level, the logical query is: what motivates the Fed to vary the interest fee?
The market spends lots of time making an attempt to work this out. Unfortunately, we’ve run out of area to handle that however it’s value studying by the Fed’s construction and objective in its personal phrases right here: Structure of the Federal Reserve System.
In closing, the Fed dictates the greenback’s interest fee, which dominates different central banks’ home interest rates that finally feed into monetary market asset costs and, thus, our investments’ returns.
As common, the actual world is extra nuanced and difficult, however this text ought to assist you higher grasp why interest rates and the Fed dominate many monetary market discussions.
