Korea's tiered basic pension pays 1.54 million seniors less next year than current law would

Over a full year at the maximum payment, the bottom 30% come out ahead of current law and the next 15 percentiles fall behind it ^[17][18]. A senior in the bottom 30% gets 349,700 won a month through March and 380,000 won for the nine months after, 4,469,100 won in all ^[17]. Current law, indexing the payment to 358,790 won from January, would pay 4,305,480 won ^[2][17]. The gain is 163,620 won ^[17]. A senior between the 30th and 45th percentiles gets 4,278,210 won, or 27,270 won below current law, because April only lifts that group to the rate the existing system would have paid from January ^[18][5].

Across the 5.168 million seniors in the bottom 45%, the withheld adjustment totals about 140.9 billion won ^[20]. Some 41.9 billion won of it comes from the 30th-to-45th band, the group with no offsetting increase ^[22]. The government puts the plan's added cost next year at about 600 billion won over keeping the current system ^[13]. Repaying the first quarter would take that to roughly 741 billion won, about 23% more ^[21].

The freeze does solve one design problem. Paying everyone the indexed 358,790 won in January, as current law requires, would include the 45th-to-70th percentile bracket that the plan holds flat all year ^[2][11]. That bracket would then take a 9,090 won monthly cut in April ^[23]. A top-up paid to the bottom 45% after April avoids the cut, and the government considered it before rejecting it over cost and fairness ^[7]. "If we belatedly pay the amount not reflected in the first quarter, it could create a fairness problem with the 45th to 70th percentile, whose maximum payment stays frozen even after April," a government official said ^[8].

The plan's own schedule undercuts that argument. From April the bottom 30% receive up to 380,000 won a month against 349,700 won for the 45th-to-70th bracket, a gap of 30,300 won set by design ^[25]. The disputed top-up is 9,090 won a month for three months ^[3]. "This is billed as an overhaul tilted toward the poor, yet for the poorest seniors on livelihood benefits the increase disappears through benefit cuts, and seniors in the bottom 45% will not even receive three months' worth of inflation adjustment," said Rep. Lee Dal-hee of the People Power Party, who obtained the ministry's budget documents ^[15][4].

Lawmakers amending the Basic Pension Act late this year can still fund the January-to-March adjustment ^[6]. "The government should reflect the inflation adjustment from January through March as current law requires," Lee said ^[16]. The ministry could finish its decree and systems early, though it says April is the earliest possible date ^[6]. Or the freeze stands and the roughly 141 billion won is never paid ^[20]. I think the third outcome is the default. The three-month systems lead time explains the April start. Withholding indexation before it is a separate decision ^[26], and the government rejected the retroactive fix on cost and fairness grounds ^[7]. The view would be wrong if the ministry showed that a one-off top-up after April needs system work beyond what tiering already requires.
