Looking for portfolio feedback- GGUS/UGL/Senior AUD bank bonds

I'd like to ask for some feedback regarding the thesis behind this long-term strategy as an Australian investor (40% GGUS/30% UGL/20% AUD cash/senior bank bonds, 10% aussie miners/personal stock picks) with 20% bands, yearly rebalancing), where it could go wrong, and for constructive critique. The basic premise is that over the next 7-10 years, the USD is expected to depreciate relative to the AUD (mean-reversion), and a number of other considerations, like higher US inflation to be expected. This is for a number of reasons, mainly due to geopolitical risk as countries move away from US treasuries and into gold, but also due to the stated and expected policy of the US government that they want the dollar to be lower. In addition, I do not see a politically feasible way for the US in the medium term to rebalance the debt-to-GDP ratio without higher levels of inflation than normal. US spending seems relatively fixed in terms of Medicare/Social Security, and is only expected to increase over the coming decades due to a demographic squeeze, so only inflation or higher taxation are viable long-term solutions (unless the US gets rid of the above). Given the political paralysis, higher taxation is unlikely, and very unlikely for the next 3 years while Trump is in office (besides tariffs, which do not meaningfully compensate for tax cuts). GGUS is 80-100% overall AUD currency-hedged S&P500 exposure, UGL is 60%ish USD-denominated gold exposure, and the 20% cash/Australian senior bank bonds are used for rebalancing when there is a crash. There are a few possible bad scenarios I have considered, and how this portfolio would play out. \-------------------------------------------------------------------------------------------------- **1. War/Significant geopolitical event** GGUS will likely crash, UGL will likely rocket as a safe asset in times of global chaos. Enables rebalancing. I expect this will be more likely in the medium term as the effects of climate change and productive capacity in the Global South decrease (climate refugees etc.). **2. Persistent US inflation** Since I'm hedged with the AUD in GGUS this is not a major concern for me, and since economically companies price based on inflation, I'm economically long higher levels of inflation and lower interest rates (expected in the near term). Gold is also useful for this. **3. Stock market crash (bubble popping)** This would likely be due to higher interest rates reducing discount rates or a bubble popping. In the near term, stocks will fall. Gold may be mixed effects, there for rebalancing. Cash also there for rebalancing. Appears there's a long-term mean reversion between stocks and gold but generally these are uncorrelated assets which is why this is useful. **4. Deflation** I don't believe that this is likely in the macroeconomic environment we are in- central banks would be likely to decrease interest rates. However, under this scenario, the portfolio does lose considerable value. **5. Tariff death spiral** Stocks will crash, gold will likely soar as it's not dependent on government policy. Rebalance, buy the dip, TACO. **6. Bond vigilantes** This is possible in the next 5-10 years if inflation is too high and long-term bond investors are not happy with a dovish Fed's low interest rates. Cash/short-term senior Australian bank bonds allow for rebalancing, and I'm happy to hold. Gold/cash allows for rebalancing into the significantly depressed GGUS. **7. The big 4 Australian banks default on senior bank bonds** I think this is very unlikely and would probably mean I have bigger problems to worry about than my portfolio. Similar level of risk to the Australian government defaulting, slightly higher, but an additional risk I'm willing to take for the slightly higher yield on cash. **8. Gold prices decrease** This is possible- gold seems to have short upswings and long periods where it does nothing, likely because of saturation from miners. Given volatility decay losses associated with UGL, I may experience more losses as a result, but for me it's worth the insurance policy. In the long term, it's an uncorrelated asset which will appreciate in value as mining grades will decrease, and will be a useful store of value which eventually appreciates to match inflation or better than inflation. So I'm fine with this risk. \----------------------------------------------------------------------------------------------------- Are there any future likely scenarios I haven't considered? I've also backtested this portfolio and it seems to have done pretty well in the past (\~14-15%) with okay drawdowns, not a predictor of future returns, but still. Ideally, I still would've preferred a 2x or 3x VT LETF instead for the 40% portion (for broad international diversification and lower daily volatility eating into volatility decay), but that doesn't really exist in a liquid form. Perhaps the only semi-likely scenario I've thought of is that the US gets its shit together for inequality, but that's unlikely. **TL;DR:** I'm a young Australian investor looking to FIRE eventually. I'm stress testing a 40% GGUS/30% UGL/20% senior Australian bank bonds (QPON)/10% fun money portfolio (with 20% bands and yearly rebalancing) and would like some feedback/thoughts on where it could go wrong in the long term. The simplest idea is that gold and stocks are uncorrelated assets and allow for yearly rebalancing for tax purposes, and the USD will have to inflate more than normal in the longer term due to political reasons (see US debt-to-GDP), enabling higher returns in currency-hedged leveraged S&P500 and gold. If anyone does find a suitable 2.5x or 3x VT LETF I'd be very happy to switch to that instead for the 40% portion.
