Dollar stalls on Fed pause bets: how markets price rate expectations

The US dollar finished a fourth straight week of gains, according to Investing.com, but it gave some of that back on Friday. The reason, FXStreet reports, is that US data confirmed investors' expectations that the Federal Reserve would hold rates steady at its October meeting.

FXStreet says the Australian dollar gained 0.38% on Friday and 0.58% over the week, trading at 0.6983. A separate FXStreet report notes the Dollar Index, a measure of the dollar against a basket of major currencies, traded near 102.25 and has made a lower high in each session since Wednesday. Our sister site has a full wrap of the dollar's fourth weekly gain. You can follow the index on a DXY chart.

What is market-implied rate expectations?

News reports often say traders are "betting" on a Fed pause or "pricing in" a rate hike. This means something specific. Traders buy and sell contracts whose value depends on future central-bank interest rates. From those prices, analysts work out what the market as a whole expects.

The result is usually shown two ways:

• A probability for the next meeting, such as "80% chance of no change".
• A total in basis points by a later date. One basis point (bp) is 0.01 percentage point, so 25 bps equals 0.25 percentage point.

These are not forecasts from the central bank. They are the crowd's current view, and they change every day as new data arrives. Currencies often move when these expectations shift, because a higher expected rate can make a currency more attractive to hold.

A worked example

investingLive published a snapshot of market pricing after this week's events. Here are some of its figures:

Now some simple arithmetic. We assume a standard move is 25 bps.

1. Fed, next meeting. An 80% chance of no change leaves a 20% chance of a hike. 0.20 × 25 bps = 5 bps priced for that meeting. That is small, which is why reports talk of "pause bets".
2. Fed, year-end. 25 bps ÷ 25 bps = 1. The market still expects about one full hike later, just not in October.
3. BoE, year-end. 35 bps ÷ 25 bps = 1.4. The market expects one hike and sees a 40% chance of a second.

Now the currency side. At the ECB reference rates, the official daily fixings from the European Central Bank for 9 October, GBP/USD rose from 1.3207 to 1.3220. That is 1.3220 − 1.3207 = 0.0013, or 13 pips. AUD/USD rose from 0.6943 to 0.6981, which is 38 pips or 0.54%.

Why it matters for new traders

Markets react to surprises, not to news that is already priced. If traders already give an 80% chance of a Fed hold, a hold itself may barely move the dollar. A hike would be a shock.

This is why data releases matter. investingLive reports that US consumer sentiment came in at 46.3 against 47.8 expected, while one-year inflation expectations rose to 4.7% from 4.6%. Figures like these can nudge rate pricing in either direction.

The next big test is close. investingLive notes that the US CPI inflation report is due on Wednesday, with Australian employment that evening and US retail sales on Thursday. Before such releases, check what the market already expects. The surprise relative to that view is what tends to move prices. Follow the Aussie on an AUD/USD chart.

Key terms

• Basis point (bp): 0.01 percentage point. 25 bps = 0.25 percentage point.
• Pricing in: when expected news is already reflected in market prices.
• Pause bets: market positioning for a central bank to leave rates unchanged.
• Dollar Index (DXY): a measure of the dollar against a basket of major currencies.
• Reference rate (fixing): the ECB's official daily exchange rate, not a live quote.
