The Fed springs a surprise on investors – are there more to come?

Last night, the US Federal Reserve sprung a surprise on markets.

It was more aggressive about inflation than anyone expected.

At this rate, it thinks we might see some interest rate rises by the end of 2023.

If you’re wondering why that was enough to give investors an unwelcome dose of reality, then read on.

Why markets have become much more sensitive to the Fed’s every motion

Before the modern money-printing era, central bank decisions used to be quite simple things to analyse.

The central bank – be it the Federal Reserve or the Bank of England – would raise interest rates, cut interest rates, or leave them where they were.

If you were looking for a bit more nuance, you might look at how many people voted in line with the decision, but even then, the level of dissent varied widely – you often got dissenters on the Bank of England, whereas almost every Fed decision was unanimous.

That was it: one big number to watch, and the occasional twitch of the eyebrow to add a wee thrill for the forecasters.

Today, analysing central bank decisions is a lot more complicated. It’s a mini-cottage industry all to itself. It involves running entire statements through a word processor to pick up on changes to the placement of commas and minor syntax shifts.

It means trying to work out what’s happening with a handful of money-printing programmes and bond-market plumbing issues.

And while interest rates themselves don’t matter as much, because they’re stuck at zero and – it’s assumed – will be for some time, what does matter is whether the central bank is thinking about raising rates at some point in the future.

This in turn means – in the case of the Fed, which like it or not, is the most important central bank – decoding “dot plots” which show exactly where each individual member thinks interest rates will be by a given year.

And it means the Fed boss – currently Jerome Powell, but his predecessors have had to learn this too – has to speak very carefully indeed at the post-match press conferences.

We’ve highlighted the absurdity of all of this before, but it really is extraordinary. The point of free markets is to allocate capital efficiently. Yet the whole edifice comes to a nail-biting pause every six weeks or so, and can abruptly shift direction based on a stray comma.

Why the increased sensitivity? A lot of it is a side-effect of zero or near-zero interest rates. When rates are at 5%, 0.25% is a small move. When rates are at 0.1%, 0.25% is a very big move indeed.

If you’re struggling to understand this, then imagine an interest-only mortgage. If the interest rate goes up from 5% to 5.25% – it doesn’t matter. Almost regardless of how recklessly you’ve borrowed, that move won’t ruin your finances. At £500 a month, your payment would rise to £525.

If you borrowed at 0.1% however (let’s imagine you’re in Denmark, where they even have negative rate home loans for some), and the interest rate goes up to 0.25%, your monthly payment will more than double. So you’d go from paying £500 to about £1,250. (This is a heavily stylised example, but you take the point.)

That’ll ruin you. And that’ll have you watching your bank manager like a hawk.

The most obvious change is in the US dollar

Anyway – so what happened yesterday is that the Fed did a few nudges and winks that turned out to be more hawkish than everyone (yours truly very much included) had expected.

The “dot plot” shows that more Fed members expect rates to have risen. As Helen Thomas of Blonde Money points out, in March just seven Fed members expected at least one rate hike in 2023. Now 13 do. And overall they expect two rate hikes, not just one.

As I said, this is technically a tiny shift. But if markets have been betting on “lower for longer” and “liquidity to the gunwales” then they’re not going to be terribly happy about hearing even a modicum of doubt introduced there.

As Thomas also points out, this rather goes against what the Fed has been trying to say publicly, which is “we don’t care about inflation just now because a) it’s transitory and b) jobs are more important”.

Now it feels to markets as though the Fed is wavering. Either they think inflation is going to be more persistent, or growth stronger.

What does this all mean in practice for you as an investor?

Hands up, as I wrote on Monday, I thought the Fed would err on the side of dovishness. It didn’t.

As a result, the US dollar has shot up. A stronger US dollar is (in this context at least) is a warning to asset markets. The world’s most important currency is getting stronger, which in effect means that global monetary policy is a little tighter.

We haven’t seen massive fallout yet. As Dominic noted yesterday, some froth has been coming off commodity markets and precious metals took a hit last night. As for wider markets – the Nasdaq slipped (it’s arguably the most interest-rate sensitive market) but the FTSE 100 is little changed (it helps that the pound has dived against the dollar, which tends to prop up the FTSE 100 as it has a lot of dollar-earning stocks).

What I’m looking for now is to see the Fed walking this back. Jerome Powell remained at pains to emphasise “outcomes” rather than forecasts, and pointed out that the dot plot is “not a plan”. He also said that they haven’t discussed reducing money printing in detail: “You can think of this meeting that we had as the ‘talking about talking about meeting’... we’re still a ways from our goal of substantial progress.”

In short, this was a shake for markets. A reminder not to bet the house on one outcome. So far it seems to me that the underlying “let’s not be too hasty” message is still intact.

But markets won’t take that for granted any more. And that could mean turbulence especially in the thinly-traded summer months.

You don’t need to make any big changes to your strategy. You might just need to be prepared for more ups and downs up ahead.
