If high income already maxed out cpf mah. There's a cap of 37.74k annually I think.I think bond is not a good idea because cpf is one of world safest bonds. Almost cannot scam because you cannot withdraw unless you fulfil some conditions. If you have outstanding mortgage, 1 is to repay your cpf usage for mortgage loan. You get 2.5% payout almost with little risk. Singapore savings bonds you need to put long term else they give you 0.85% per annum. I like equities a lot because in the world of inflation, what is better than to invest in the world greatest companies? Again this is high risk and you may suffer 50% paper lost so need to be able to stomach the losses
Want to put in more also cannot.
