For a country trying to avoid the menace of deflation, South Korea is receiving timely help from unusual quarters - the country's landlord and their tenants.
Interest rates at historic lows have wrought a change in traditional rental contracts that could gradually unleash tens of billions of dollars for more productive uses like consumption and home buying.
Landlords have for decades operated the "jeonse" rental system, whereby tenants pay a deposit that can be more than half the home's value instead of having to pay a monthly rent.
There is a huge pool of funds being under utilized. Nomura estimates that there was some $400 billion tied up in jeonse deposits in 2012, equal to one-third of South Korea's annual economic output.
But the jeonse system appears to be going out of fashion, as most landlords can't make high enough returns from stashing the money in bank deposits paying just 2.5 percent - they will go down again after the central bank lowered its policy rate further last week.
Using the funds as leverage to further invest in the real estate market holds little attraction for landlords either. Prices have been flat.
Jeonse accounted for slightly more than half of rentals early this year, sharply down from nearly 70 percent in early 2011, land ministry data showed.
"The sharp drop in interest rates is the most important factor behind this phenomenon as home owners want to make up for the shrinking income as much as possible," Kim Eun-kyung, a consultant at Samsung Securities said.
"The jeonse deposit money has mostly been illiquid, but the declining jeonse contracts will turn the money more liquid, more ready to spend on consumption or paying back loans, although this will happen very gradually," Kim added.
South Korea's ageing population - the number of working-age people between 15 and 64 will begin shrinking from 2017 - also heralds lower demand for rentals, as typically demand comes from younger people.
Landlords have responded to the changing market environment by either charging a monthly rental, or asking for a substantially higher jeonse deposit, which should further reduce demand for such rentals.
Either way, the prospect of less money locked up in the jeonse system, and more becoming available for people to spend, invest, or buy their own homes should be a boon for the economy.
Young Sun Kwon, an economist at Nomura in Hong Kong and a former official with South Korea's central bank, estimated that renters have borrowed about 64 trillion won ($60 billion) to fund jeonse deposits.
The trend away from jeonse rentals comes at a good time for Finance Minister Choi Kyung-hwan, who fears Asia's fourth-largest economy could go the way of Japan and slip into deflation. The extra money coming into circulation will help his strategy to lift asset prices as a way to boost consumption.
Lee Yeon-hee, an office worker in her 20s in Seoul, had rented through a jeonse contract, with a deposit of 80 million won, until her landlord demanded an extra 15 million won increase. At the same time, with South Korea's economy slowing, her father's small-scale machine assembly business failed.
"I couldn't accept the demand for an increased jeonse," Lee said. She now pays a monthly rent of 400,000 won, and has used the returned deposit to pay off a loan and support her parents.
