Key Points

  • Chase ran a tiered transfer bonus to Marriott Bonvoy in summer 2025, peaking at 65% through June 30 before stepping down to 50% through August 15.
  • At the 65% rate, 1,000 Ultimate Rewards transferred as 1,650 Bonvoy points, the most generous Chase-to-Bonvoy promotion the programs had run.
  • Chase rarely runs transfer bonuses to Marriott, so the next cycle is worth watching for, not predicting.

TL;DR

Chase offered a 65% transfer bonus from Ultimate Rewards to Marriott Bonvoy through June 30, 2025, dropping to 50% through August 15. Promotions between the two programs are uncommon, so the offer was unusual and is now closed.

What the bonus was

Chase ran a tiered transfer promotion from Ultimate Rewards to Marriott Bonvoy during summer 2025. From the launch date through June 30, 2025, members received a 65% bonus on transfers, meaning every 1,000 Ultimate Rewards points moved to Bonvoy as 1,650 Marriott points. From July 1 through August 15, 2025, the bonus stepped down to 50%, or 1,500 Bonvoy points per 1,000 Ultimate Rewards.

The mechanics matched Chase's standard transfer flow: 1,000-point minimums in 1,000-point increments, processed within roughly two business days, and irreversible once submitted. Eligibility required a Chase card that earns Ultimate Rewards, including the Sapphire Preferred, Sapphire Reserve, Ink Business Preferred, and the Ink Business Cash and Unlimited when paired with one of those cards.

The promotion ended on August 15, 2025, and Chase has not announced a replacement. Both programs have since returned to their standard 1:1 transfer ratio.

Why Chase and Marriott rarely promote together

Marriott Bonvoy is a transfer partner on most major flexible-points currencies. Both Amex Membership Rewards and Chase Ultimate Rewards ship points to Bonvoy at 1:1, but the relationship between Chase and Marriott has been unusually quiet on the bonus front.

Marriott's deeper co-brand alignment is with American Express, which issues most of the Bonvoy-branded U.S. consumer cards (the Bonvoy Brilliant, Bonvoy, and Bonvoy Business are Amex products). Chase issues the Marriott Bonvoy Boundless and Bonvoy Bold, but the network of co-brand cards is split between the two issuers under a longstanding arrangement. That split has meant Chase's points-transfer marketing tends to lean toward airline partners like United, Southwest, World of Hyatt, and Air Canada Aeroplan, where the value math is cleaner for the kind of premium-cabin redemptions Ultimate Rewards is best known for.

The 2025 bonus broke the pattern. It was the first widely promoted Chase-to-Bonvoy bonus in years, and the 65% top tier was the highest rate either program had offered to the other.

How the math actually worked

The headline rate was generous, but the underlying value comparison still favored holding Ultimate Rewards in most cases. Chase points redeem at a fixed 1.25 cents per point through the travel portal on the Sapphire Preferred and 1.5 cents per point through Points Boost categories on the Sapphire Reserve, before any transfer-partner upside. Marriott Bonvoy points, by contrast, typically deliver 0.6 to 0.8 cents per point in real redemption value, with the high end concentrated at luxury properties during peak demand.

Run the numbers on a 50,000-point transfer at the 65% rate: 50,000 Ultimate Rewards became 82,500 Bonvoy points. At a typical 0.7-cent valuation, that's about $577 in hotel value, against the roughly $625 those Chase points would have produced at 1.25 cpp through the portal. The bonus closed the gap; it didn't reverse it.

Where the transfer made sense was at the high end: a 100,000-point night at a Ritz-Carlton Reserve or a five-night award at a peak St. Regis, where the cash rate could clear $1,500 per night. In those cases, the effective per-point value crossed two cents and the transfer cleared the threshold to be worth it. The other useful case was topping off. A member 15,000 Bonvoy points short of a redemption could fill the gap with about 9,000 Ultimate Rewards at the 65% rate.

What to watch for

Chase has not signaled a return of the bonus. The pattern matters: Marriott runs a transfer-bonus calendar of its own, and bonuses from Chase historically cluster in summer months when leisure-travel demand is highest. If a future promotion runs, it will most likely surface in the May-to-August window and follow the same tiered structure, with a higher headline rate early that steps down before the offer ends.

Members who keep Bonvoy in their redemption rotation should track Marriott's transfer-bonus history page and watch for Chase email outreach to Ultimate Rewards-earning cardholders. The 65% rate set a high-water mark; the next bonus is unlikely to clear it but is worth acting on if a specific high-value redemption is already planned.

For most Ultimate Rewards balances, though, the airline-partner case remains stronger. Hyatt continues to be the standout hotel-side transfer for Chase points, and the United, Air Canada, and Air France-KLM Flying Blue partnerships consistently deliver the per-point value that justifies parking points in Ultimate Rewards in the first place.
