Between 01:00 GMT on Wednesday, October 28 and roughly 03:00 GMT on Friday, October 30, five of the world's largest central banks announce interest rate decisions. The Reserve Bank of New Zealand opens the run, the Bank of Canada and the US Federal Reserve follow the same day, the European Central Bank decides on Thursday and the Bank of Japan closes on Friday. Only one of the five was priced to move a week ahead. The interesting part is what the other four are expected to say.

Four holds, one hike

As of October 19, markets priced a rate hike only for the RBNZ, according to a preview by the broker Admirals that cites each central bank and MPA New Zealand. Traders put the odds of the RBNZ lifting its cash rate from 2.75 percent to 3.00 percent at roughly 80 to 85 percent. Everything else was priced as a hold.

For the Fed, CME FedWatch showed an October hike chance of about 15 percent in mid-October, falling to 8 or 9 percent later in the week, according to Tiger Brokers, Schwab and Yardeni Research. Seventy of 73 economists in a Reuters poll expected the ECB to keep its deposit rate at 2.50 percent. Swaps priced under 5 percent odds of a Bank of Japan move from 1.25 percent, BBH told FXStreet.

The Bank of Canada is the unsettled one. RBC and TD expected it to hold at 2.25 percent, per MPA Canada, while Yardeni Research's weekly outlook cited market pricing of about 85 percent for a hike to 2.50 percent. Neither pricing nor economists agree, and that disagreement is the signal.

The backdrop is inflation, and oil

Inflation has turned back up. US consumer prices rose 3.7 percent in the year to September, with core at 2.6 percent, above the 3.6 and 2.5 percent forecast, according to investingLive. We covered that release when September's hot US CPI revived bets on a Fed hike. Euro-area inflation hit 3.8 percent in the flash estimate, a three-year high, according to RTTNews, and UK CPI reached 3.5 percent, with the same energy shock behind both. Canada's CPI was 3.1 percent in September and New Zealand's 4.1 percent in the second quarter.

Oil explains much of it. West Texas Intermediate traded around $101 a barrel on Thursday, per Schwab, and investors are watching the Middle East for further supply disruption, Trading Economics reported. A Yelza market calendar said that as long as tensions in the Strait of Hormuz persist, oil stays a major risk to inflation and therefore to rate policy.

The Fed: Warsh without a script

The Fed raised its target range by 25 basis points to 3.75 to 4.00 percent on September 16, according to its statement. This week's meeting is the first since Chair Kevin Warsh distanced himself from the committee's own projections at his September press conference, saying they were not his, Tiger Brokers reported. He has also dropped traditional forward guidance.

The market's view is that October is a pause and December is live. Citi said on October 14 that it expects a 25 basis point hike in December, after which the Fed would hold until cuts begin in June 2027. Futures priced about an 84 percent chance of a hike before year-end, per Schwab and Yardeni. Because Warsh offers little guidance, the press conference at 18:30 GMT may move markets more than the statement.

Why a hold is not a non-event

A "hawkish hold" leaves rates unchanged while keeping a hike on the table. In a cluster of five decisions, each can move the dollar leg of the next. A hawkish Fed on Wednesday could push USD/JPY toward 160 before the Bank of Japan even meets.

Japan is the pressure point. The BoJ raised its rate to 1.25 percent on September 18, the highest since 1995, on a 7-2 vote, and the yen weakened afterwards because Governor Ueda gave few hawkish signals, per BabyPips. The gap to the Fed's midpoint is about 262 basis points, the widest among the five banks, in Admirals' calculation. In August a joint Japan-US intervention drove the pair from near 164 to about 155, but it climbed back above 159 within days, investingLive reported. USD/JPY closed at 158.17 on October 20.

Who might blink

The ECB deposit rate is 2.50 percent after two hikes this year. In the Reuters poll, 64 of 73 economists expect another 25 basis point hike in December, and Lagarde has described the appropriate response as measured, because the energy shock has not yet reached wages, per Pound Sterling Live. The BoJ has about 80 percent odds of a hike in December in swaps. The RBNZ faces a general election on November 7 and a currency near a 15-year low on a trade-weighted basis, FXStreet reported.

Put together, three of the five banks are expected to hike in December. This week is a pause, not a peak. For anyone with a loan, a mortgage or savings in dollars, euros or yen, the practical message is that rate relief is not on the calendar.

Gold shows the pressure. It settled near $4,010 on Friday, down about 4.2 percent on the week and below $4,000 for the first time since mid-July at one point, NordFX reported, because higher oil kept December hike risk alive and real yields outweighed safe-haven demand.

What to watch

Three moments matter more than the headline numbers. The first is the Fed press conference on Wednesday evening, where Warsh either confirms or denies the December path. The second is the ECB on Thursday, where Lagarde can rule December in or out. The third is the BoJ on Friday in thin Asian trading, where any yen move runs straight into the weekend.

If all five do what markets expect, the surprise will be the lack of one. The week then ends where it started: with inflation above target in most places, oil above $100, and December as the next date that matters.
