ZAR/JPY to 9.60: carry still prices a six-point gap

The South African rand/Japanese yen (ZAR/JPY) reaches 9.60 by December 18, 2026 in the base case, 9.85 in the bull case and 9.15 in the bear case. The mechanism is the still-open 600-basis-point gap between a South African Reserve Bank (SARB) policy rate of 7.25% and a Bank of Japan (BOJ) call rate of around 1.25%. On November 13, 2026 the European Central Bank (ECB) fixed euro-yen at 176.83 and euro-rand at 18.7481, so the cross is 9.4319, down from 9.7028 on September 18.

Key Levels:

• Asset: ZAR/JPY at 9.4319 — ECB references, November 13, 2026 (176.83 divided by 18.7481)
• Base case target: 9.60 by December 18, 2026 — 1.8% above the November 13 print
• Bull case target: 9.85 — a SARB hike on November 19 with the BOJ on hold
• Bear case target: 9.15 — a call rate around 1.50%, or dollar-rand through 17.40 with dollar-yen near 160
• Major support: 9.4221 — ECB-window low, October 30, 2026
• Major resistance: 9.6517 on November 5, 2026, then 9.9944 on August 26, 2026
• Invalidation level: a weekly close below 9.20 — clear of the October 30 low

How the cross is measured

ZAR/JPY here is euro-yen divided by euro-rand on the ECB euro reference grid. The window runs from August 17, 2026 to November 13, 2026. Dollar-yen and dollar-rand use that grid divided by the euro-dollar reference, and a dealing spread sits outside the implied mid. The SARB statement of September 23, 2026 sets the policy rate at 7.25% from September 25. The BOJ statement of September 18 sets the uncollateralized overnight call rate at around 1.25% from September 24, and the October 30 statement keeps it there. The horizon is December 18, 2026, the second day of the next meeting on the BOJ calendar. The SARB press conference of November 19, on the Reserve Bank webcast page, falls inside that horizon.

The rand cheapened faster than the yen

From the August 26 high of 9.9944 to 9.4319 on November 13, ZAR/JPY fell 5.6%. Dollar-yen moved from 159.07 to 160.00, up 0.6%, while dollar-rand moved from 15.9160 to 16.9635, up 6.6%.

ZAR/JPY is the yen value of one rand, and the ECB euro reference grid fixes it with two other prices. On November 13, 2026, euro-yen of 176.83 divided by euro-rand of 18.7481 equals 9.4319. Euro-dollar of 1.1052 on the same grid implies dollar-yen of 160.00 and dollar-rand of 16.9635, and 160.00 divided by 16.9635 returns the same 9.4319. From September 18 to November 13 the cross fell 2.8%, dollar-yen rose 1.3% and dollar-rand rose 4.2%, so the rand's loss against the dollar was about three times the yen's. A year-end path for the dollar-rand rate therefore dominates the next five weeks. The 9.60 base case needs dollar-rand near 16.67 if dollar-yen stays near 160, because 160 divided by 16.67 is 9.60, a partial give-back of the climb from 16.42 on November 5 to 16.96 on November 13.

"So far, our modelling indicates that prevailing policy settings are sufficient to return inflation to target after the initial shock has passed. We remain firmly focused on our mandate, and will act as needed to prevent higher inflation from becoming entrenched."

— Lesetja Kganyago, Governor, South African Reserve Bank (South African Reserve Bank, October 29, 2026).

Why 9.60 still follows from a six-point gap

The policy gap is 600 basis points. Statistics South Africa's Consumer Price Index release P0141 put September inflation at 4.5%, up from 4.4% in August. That print sits 1.5 percentage points above the 3% target and 0.5 percentage points above a tolerance of plus or minus one percentage point. The September statement records upside risks to inflation and a Quarterly Projection Model (QPM) with the policy rate broadly stable through the rest of the year. Footnote 13 puts the fourth-quarter 2026 average at 6.98%, 27 basis points under the 7.25% rate now in force. The base case is a hold, leaving the gap at 600 basis points.

On October 30 the board voted eight to one to keep the call rate at around 1.25%. Takata Hajime proposed around 1.5%, and the board defeated the proposal. December 17 and December 18 carry a dash in the Outlook Report column, and the next Outlook Report is dated January 22, 2027. September's change to 1.25% used a meeting with the same dash, so December 18 can deliver a hike or a second hold. The same pattern runs through the peso-yen carry case and the krone-yen path into a Norges Bank hold on the forex desk.

"We will adjust monetary policy as appropriate so that underlying inflation becomes anchored around 2%."

— Kazuo Ueda, Governor, Bank of Japan, as translated by Reuters from the October 30, 2026 news conference (Reuters).

Where a ratio model goes wrong

The identity is also the limit. A rise of the same proportion in dollar-yen and dollar-rand leaves ZAR/JPY unchanged, so a broad dollar move can look large in each leg and flat in the cross. The September week is the clean example: both banks tightened, and the cross dipped 0.4%, from 9.7028 on September 18 to 9.6603 on September 23. Jane Foley, senior FX strategist at Rabobank, wrote on October 6 that the bank maintained a three-month dollar-yen target of 155.00, looking for the next BOJ step in December. Put 155.00 over the November 13 dollar-rand rate of 16.9635 and the cross is 9.14, the bear case under another name. The base case treats 155 as a three-month destination from early October, running past December 18. If the yen covers that distance inside five weeks, the path to 9.60 gives way to 9.15.

"We maintain a 3-month USD/JPY target of 155.00."

What would invalidate this base case

The path to 9.60 by December 18 breaks if any one of these four prints arrives.

• A weekly close below 9.20 would sit about 2.4% under the October 30 low of 9.4221, and would mark the retracement as finished in cash.
• A BOJ call rate of around 1.50% on December 18, Takata's defeated proposal, would cut the gap from 600 basis points to 575 and hand the cross to the 9.15 bear case if dollar-yen moved towards 155.
• A SARB cut on November 19 would cheapen the rand into the Tokyo meeting, against a QPM that describes the rate as broadly stable through the rest of the year, with a fourth-quarter average of 6.98%.
• Dollar-rand above 17.40 while dollar-yen holds above 159 puts the cross at 9.14, because 159 divided by 17.40 is 9.14, the bear case through the rand leg alone.

What to watch into the December decision

The SARB webcast page names November 19, 2026 for the next Monetary Policy Committee decision. Beyond September CPI at 4.5%, the committee will have the next Statistics South Africa release. A headline still near 4.5% keeps the upside-risk language alive. A step down towards the 4% edge of the tolerance band would make the 6.98% fourth-quarter average look more like a prompt to ease. The BOJ meets on December 17 and December 18, and the 9.60 path expires on December 18, the second day. The grid levels between the meetings are 9.4221 and 9.6517. A cross still under 9.45 on the morning of November 19 would leave the repair unfinished.

TL;DR

ZAR/JPY reaches 9.60 by December 18, 2026 in the base case, 9.85 if the SARB hikes on November 19 and the BOJ holds, and 9.15 if Tokyo lifts the call rate towards 1.50% or the rand cheapens further. The ECB grid for November 13 puts the cross at 9.4319, down 2.8% from 9.7028 on September 18. The gap is still 600 basis points, and September CPI was 4.5%. A weekly close below 9.20, a BOJ move to around 1.50%, a SARB cut, or dollar-rand above 17.40 with dollar-yen still above 159 breaks the path.

FAQ

Where does the 9.60 base case for ZAR/JPY come from?

ZAR/JPY reaches 9.60 by December 18, 2026 from an ECB-implied 9.4319 on November 13. With dollar-yen near 160, the cross hits 9.60 when dollar-rand is about 16.67. The path assumes a SARB hold at 7.25% on November 19 and a BOJ hold near 1.25% on December 18. A SARB hike maps to the 9.85 bull case, and a BOJ move towards 1.50%, or dollar-rand through 17.40, maps to the 9.15 bear case.

How wide is the policy gap between South Africa and Japan?

The gap is 600 basis points. The SARB raised the policy rate by 25 basis points to 7.25% on September 23, 2026, effective September 25, and the vote was unanimous. The BOJ guideline is an uncollateralized overnight call rate of around 1.25%, set on September 18 by a seven-to-two vote and held on October 30 by eight to one.

When does the Bank of Japan next decide on rates?

The Bank of Japan calendar lists the next meeting as December 17 and December 18, 2026, and the date used here is December 18, the second day. That row carries a dash where an Outlook Report would sit, and the next Outlook Report date on the page is January 22, 2027. September's change to a 1.25% call rate used a meeting with the same dash, so a December hike and a second hold are both open. The base case uses the hold.

What level would invalidate the ZAR/JPY base case?

A weekly close below 9.20 invalidates the path to 9.60. The ECB-window low is 9.4221 on October 30, and the November 13 print of 9.4319 sits just above it, so 9.20 is about 2.4% under that shelf. Three further events do the same work: a BOJ call rate of around 1.50% on December 18, a SARB cut on November 19, or dollar-rand above 17.40 while dollar-yen holds above 159. Any one of the four is enough on its own.
