Oyu Tolgoi's loan just got cheaper. Mongolia is calling it history.
The government reports the shareholder loan rate fell by 2.5-2.6 percentage points, with the review cycle shortened from seven years to three. In May the two sides halved management fees.
The June agreement is expected to slash overall project costs by $8.4 billion and increase Mongolia’s future returns by $4 billion over the mine's life.
Prime Minister Nyam-Osoryn Uchral calls the package a historic win, timed neatly to his government's first 100 days.

The shareholder loan is priced off a floating benchmark, 3-month SOFR plus a 6.5% margin and a small credit adjustment, compounding quarterly. The cut applies to the margin. With SOFR at 3.66%, the effective rate drops from roughly 10.4% to 7.9%, but the base still floats. If American rates climb, Mongolia's interest bill climbs with them. The next review lands in 2029, after the 2027 presidential race and the 2028 parliamentary election. That timing suits both sides. The government banks its win now, and nobody has to renegotiate a loan rate in the middle of a campaign.
