I think that the Public Gold Investment Account is one of the the easiest way to get exposure to the gold market. The difference between the buying and selling prices is about 4%, which is lower compared to Maybank (7%). However this is still high, because for comparison, in Singapore banks the difference is only 0.3%! Unfortunately, last I read only sg citizens and permanent residents are eligible.
Alternatively, there's a Gold ETF listed in the Singapore stock exchange, (Street Tracks Gold, SGX Ticker: GLD 10US$). Last I checked its price was $88.84. You can buy that ETF through your stock broker just like any other stock.
However do note that one of the reasons people buy gold is because of safety. In that sense, owning physical gold (like Kijang Emas) is the best bet. By 'buying' from banks it's not real gold but 'unallocated gold'. This means that your ownership of gold is a liability to the bank, like a normal cash savings deposit. It's just a trust/agreement that they will pay you when you demand for it.
Just like a savings account, there is a risk of a 'run in the bank' where everyone withdraws their money during a banking crisis. Since some of the money has been lent out already, there isn't enough cash reserves to give to the 'latecomers'. Bank Negara guarantees the deposit to a certain amount (probably RM100k?), so that amount of cash is safe. However, bank negara doesn't guarantee the gold. If the bank goes bankrupt you don't get your gold.
Take this risk into consideration! The huge inflation caused by the federal reserve is finally showing it's ugly signs, especially when the money they print has now gone to commodity/food speculation. Rising prices causes governments to ration and suppliers to hoard, causing shortages. Shortage of food makes people hungry and all havoc breaks loose. We are living in uncertain times, although I think Malaysia as an agricultural country may not feel it that badly.
My guess is that gold will go higher as inflation gets worse. The current correction looks like a good buying opportunity. For house owners, it will be good to refinance all your BLR-pegged loans to a fixed rate (now at historic lows of ~5.7%), as I think that the BLR will be rising in the near future due to inflation.
This is just my opinion, so do your own research. At times like this we probably need to think with our guts as well
