The Korean Housing Market: Its Characteristics and Policy Responses

The Korean housing market has gained strength centering around the Seoul metropolitan area (SMA) since 2014, when it started to recover. Against the backdrop of low interest rates, the easing of real estate regulations has pushed up expectations of higher housing prices, which has led to greater demand for housing as an investment. Expectations of housing price rises, coupled with greater incentives for financial institutions to provide home mortgage loans, have caused household debt to grow rapidly. In order to stabilize the housing market in the SMA and contain the rapid household debt buildup, the Korean government has instituted comprehensive and tailored policy responses since the second half of 2017. The government’s sweeping responses cover many different areas, including macroprudential, housing and tax policies. The ranges and intensities of the policies differ by region, by household status (whether it owns houses or has taken out mortgage loans) and by the type of demand (speculative or residential) so as to increase their effectiveness and minimize any negative side effects. Thanks to the government’s policy responses, the rapid buildup of household debt has slowed recently, and the housing market in the SMA is gradually stabilizing.


Supply and Demand
Housing supply, which had fallen amid the post-crisis housing market slump, began to increase with the real estate deregulation in 2014, led by the NSMA. of growth in the number of households is higher in the SMA (2. 1%, 2000-2017) than the national average (1.8%), due to the faster growth in one-and two-person households there.

Structural Characteristics of the Korean Housing Market
The Korean housing market is characterized by the dominance of apartments among housing types, by considerable demand for housing for investment purposes, and by household-led supply of rental housing.

Apartments as a Dominant Form of Housing
As of 2016, apartments accounted for 60% of all housing units in Korea (Fig. 16.3a).
On the supply side, apartments came to predominate because they could be more effectively supplied and managed than other types of housing in response to the growing overpopulation of the SMA and other large cities during the past periods of industrialization and urbanization. On the demand side, the younger generations prefer apartments, as do the middleaged because of apartments' high liquidity ( Fig. 16.3b). They can cash in their property assets after retirement. The proportion of apartments is considerably higher in the SMA (63.2%) and other large cities (63.9%) than in the rest of the country (57.5%). 3

Demand for Housing as an Investment
Korean households have a strong tendency to own houses not only for residential but for investment purposes as well. Apartments in Korea are highly preferred as an investment because they yield high and stable profits, and are highly liquid 4 ( Fig. 16.4a). As a result, non-financial assets, such as homes and commercial Meanwhile, the popularity of jeonse, 5 a leasehold deposit system unique to Korea, tends to make it easy to purchase homes for investment purposes through so-called gap investment. It allows home buyers to easily finance a sizeable portion of the purchase price in the form of the deposits they receive for leasing the housing out. The amount of deposit is referred to as jeonse price. 6 Demand for housing as an investment is more concentrated in Seoul. As of 2016, housing units held by multi-home owners (households owning two or more homes) accounted for 53% of total housing units in Seoul, a proportion higher than the national average (49.9%). In reflection of this, the share of owner-occupiers in Seoul stood at 42.0%, well below the national average (56.8%) (Fig. 16.5a). Nationwide, the share rose from 55.6% in 2006 to 56.8% in 2016, while in Seoul it has been falling from 44.6% to 42.0% over the same period.

Household-Led Supply of Rental Housing
The Korean rental housing market differs from those in other major countries in that the household sector, more so than the public or corporate sectors, plays the main rental housing supplier role. Korean households supplied 78.9% of total rental housing at the end of 2015 (compared to 13.7% by the public sector, and 7.4% by the corporate sector), well above the figures in major countries such as the US (56.3%), the UK (53.1%), Germany (64.1%), and Japan (66.5%). Meanwhile, jeonse tenancies, which do not occur in other major countries, accounted for 35.9% of the total rental housing supplied by households in 2016 ( Fig. 16.5b). The share of jeonse is also much higher in Seoul (45.3%) and the SMA (42.0%, regional average) than in the NSMA (25.0%).

Recent Buoyancy in the SMA Housing Market
The buoyancy of the housing market in recent years, particularly in the SMA, has been driven by three factors-the persistently low interest rates, the easing of real estate regulations, and the stronger incentives for financial institutions to supply mortgage loans.

Persistently Low Interest Rates
With low interest rates having continued for a prolonged period of time, demand for investment in housing has increased. This demand has particularly increased in the SMA, as expectations of housing price growth have spread there. Housing purchases in the form of gap investment 7 have been on the rise (Fig. 16.6a), particularly in the SMA where rental demand is higher than in other areas due to the favorable educational and cultural conditions. Figure 16.6b shows how the investment in housing in Seoul by non-Seoul residents has also grown since 2014.
Meanwhile, as jeonse prices for homes have increased faster than their sales prices, and borrowing costs have become lower, demand from households switching from rental to ownership of housing has also grown. The proportion of jeonse tenants purchasing their own units rose from 7.4% in 2013 to 10.4% in 2016.

Easing of Real Estate Regulations
In an effort to boost the real estate market, the Korean government eased the housing market-related regulations drastically in 2014. In the SMA the LTV and DTI ratios were raised by up to 20pp (50% ! 70%) and 10pp (50% ! 60%), respectively. 8 This led to stronger expectations of housing price rises, and demand for housing purchases increased as a result. In addition, with the shortening of the years required before apartments are eligible for reconstruction, 9 and the easing of qualifications for having first priority to bid in new apartment pre-sale markets, 10 investor demand flowed into homes in Seoul scheduled for reconstruction as well as into new apartment pre-sale markets (Fig. 16.7a).

Stronger Incentives for Financial Institutions to Provide Mortgage Loans
The incentives for financial institutions to provide mortgage loans have strengthened, due largely to the low risk weights applied to household loans for BIS capital ratio purposes, 11 as well as to rising credit risks in the corporate sector in line with its ongoing restructuring. These stronger incentives for financial institutions to provide mortgage loans, combined with expectations of higher housing prices, have worked as major factors contributing to the surge in household debt (Fig. 16.7b). As the supply of new homes expanded in line with the easing of real estate regulations, the related mortgage lending has also increased, leading to a sharp rise in household debt. 12

Policy Responses
The Korean government has introduced comprehensive and tailored policy measures since the second half of 2017 in order to stabilize the housing market in the SMA and curb the sharp rise in household debt (FSC 2017a, b). The government's responses have been sweeping, and cover macroprudential, housing and tax policies related to household debt and the housing market. Further, in order to enhance policy effectiveness and minimize any negative side effects, the government has devised measures that vary in range and intensity depending on the target regions, the households concerned, and the types of housing demand.

Macroprudential Policies
In an attempt to manage total household debt and curb financing for speculative purposes, the government has been active in using macroprudential policies, including tightening of the regulations on all financial institutions and loans, while also developing comprehensive and systematic criteria for loan screening.
The government has tightened the LTV and DTI requirements greatly (from 70% to 40%) in August 2017, and has limited the number of home mortgage loans per household, for example from one loan per borrower to one loan per household in speculation-prone areas. To prevent any leakage from the home mortgage loan regulations, a debt service ratio (DSR) has been introduced to mandate comprehensive assessment of borrowers' debt servicing capacities for all financial institutions' loans, and will be effective from October 2018. In addition, to limit financial institutions' incentives for supplying excessive household loans several regulations have been introduced in January 2018, including an upward adjustment of the Basel risk weight from 35% to 70% for high-risk home mortgage loans with LTVs over 60%.

Housing Policies
The government has implemented policies to curb speculative demand for new apartments and for apartments scheduled for reconstruction, as that has been a main factor behind the rise in housing prices in the SMA. It has tightened the criteria for top-priority subscribers for new apartment purchasing rights, while limiting their resales by imposing a higher capital gains tax on them. The government has also tightened the requirements for apartment reconstruction, by for example revising the safety criteria for approving reconstruction projects.
outstrips that in income, and Korea's household debt-to-nominal GDP ratio (household credit statistics basis) has thus continued to increase, from 73.0% at end-2014 to 81.8% at end-2016 and 83.8% at end-2017.

Tax Policies
The taxation of housing investment has been strengthened, to curb demand for investment purposes and to heighten tax fairness. The government has raised the transfer income tax on owners of multiple homes, which became effective from April 2018, and imposed levies on excess earnings from reconstruction in January 2018. Discussions on revising the property holding tax on owners of multiple homes and expensive homes are also ongoing. This could be a more effective means of controlling housing demand for investment.

By Region
The target regions for the tighter regulations are sub-divided into speculative investment zones, overheated zones and adjustment-required zones, depending upon their respective degree of housing price rises and overheating. Each zone is subject to a different level of regulation. 13 The Gangnam districts in Seoul were designated as speculative investment zones, and are subject to the strongest regulations. Other parts of the SMA and the provincial cities are subject to relatively relaxed regulations.

By Household
The level of regulations applied to households varies depending upon whether they own multiple homes, or have taken out home mortgage loans. Households that own multiple homes are subject to a 10-20pp transfer tax add-on. Households owning only single housing units benefit from tax exemptions only after they have lived in their homes for two or more years. When a household with an existing home mortgage loan seeks an additional loan for a housing purchase, the applicable LTV and DTI ratios will be tightened by 10pp each. 14 By Housing Demand Housing demand is categorized into demand for speculative and for residential purposes. The government strictly regulates speculative demand, while providing active support for residential demand. Speculative demand is strictly controlled through tighter screening of the financing methods involved and checking on the owner-occupancy status of the borrower. On the other hand, LTV and DTI ratios are relaxed for low-income households purchasing homes for residential purposes, in order to alleviate their financing difficulties.

Policy Evaluation
Thanks to the government's comprehensive and tailored policy responses, the growth in household debt has slowed since the second half of 2017, and the housing market in the SMA has been gradually stabilizing in 2018. The rate of household debt growth was 8.1% (at year-end) in 2017, down significantly from the figures of around 10% in 2015 and 2016, in line with the tightening of the LTV and DTI limits and the other policy measures implemented in 2017 (Fig. 16.8a).
Despite the government's announcement of its housing market stabilization plan in August 2017, and its partial implementation thereof, housing prices in the SMA continued to rise for some time. In 2018, however, they have shown slower growth as the effects of the government's policies have begun to take hold (Fig. 16.8b).
For long-term housing market stability it should be noted, however, that demandreduction policies alone cannot stabilize the housing market in the SMA. There is a structural imbalance between the limited supply of new housing in that area, and the continually growing demand for it.
